I'm going to do the "right to vote" folks a favor since they are too lazy to do their homework.
In the original constitution, the word "vote" appears 16 times. None speak to your "right to vote". There are additional references to vote in the amendments. The only mention of right to vote in the amendments are conditions on which you can not be considered ineligible to vote, but do not enumerate an explicit "right to vote".
To make it even easier, I have attempted to highlight in red each time the word vote or a variation of the word occurs.
Knock yourself out providing the "right" in the Constitution.

Section 3
The Senate of the United States shall be composed of two Senators from each State, chosen by the Legislature thereof for six Years; and each Senator shall have one

Votes for each; which List they shall sign and certify, and transmit sealed to the Seat of the Government of the United States, directed to the President of the Senate. The President of the Senate shall, in the Presence of the Senate and House of Representatives, open all the Certificates, and the
Votes shall then be counted. The Person having the greatest Number of
Votes shall be the President, if such Number be a Majority of the whole Number of Electors appointed; and if there be more than one who have such Majority, and have an equal Number of
Votes, then the House of Representatives shall immediately chuse by Ballot one of them for President; and if no Person have a Majority, then from the five highest on the List the said House shall in like Manner chuse the President. But in chusing the President, the
Votes shall be taken by States, the Representation from each State having one
Vote; A quorum for this purpose shall consist of a Member or Members from two thirds of the States, and a Majority of all the States shall be necessary to a Choice. In every Case, after the Choice of the President, the Person having the greatest Number of
Votes of the Electors shall be the Vice President. But if there should remain two or more who have equal
Votes, the Senate shall chuse from them by Ballot the Vice President.
The Congress may determine the Time of chusing the Electors, and the Day on which they shall give their
Votes; which Day shall be the same throughout the United States.
