[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] The utility model provides Figure 1-5 A double-limit single-axis robot shown in the figure includes a base 1, a motor base 2 is fixedly installed at the front end of the base 1, a tail stock 3 is fixedly installed at the rear end of the base 1, a support bar 7 is arranged between the motor base 2 and the tail stock 3, and is located below the bottom of the base 1, and limit switches 8 are respectively arranged at both ends of the support bar 7. The limit switches 8 are arranged at both ends of the support bar 7, so that the robot has higher control accuracy and safety during movement. At the same time, the limit switches 8 correspond to the through grooves 9 on the base 1, which is convenient for adjusting and controlling the movement range of the robot; a through groove 9 is opened at the transverse center line of the base 1, and two limit switches 8 correspond to the through grooves 9 on the base 1 respectively. A threaded seat 6 is arranged above the base 1, and the bottom of the threaded seat 6 contacts with the contacts of the limit switch 8. This design makes it easy to replace the contacts of the limit switch 8 after wear, without affecting the normal operation of the robot, and protrusions 62 are arranged on both sides of the threaded seat 6.
[0022] Furthermore, in the above technical scheme, limit strips 4 are fixedly installed on both sides of the upper part of the base 1, and guide grooves 41 are opened on the inner sides of the two limit strips 4. The protrusions 62 on both sides of the threaded seat 6 are adapted to and slidably connected with the guide grooves 41 on the inner sides of the two limit strips 4, and the limit strips 4 can protect the screw rod 5 and prevent the threaded seat 6 from being bumped during operation. The guide grooves 41 on the inner side of the limit strips 4 increase the stability of the threaded seat 6 during movement.
[0023] Furthermore, in the above technical solution, dustproof sheets 61 are fixedly installed on both sides of the threaded seat 6 and above the raised portion 62. The two dustproof sheets 61 are respectively located above the tops of the two limit strips 4, which can prevent dust and other debris from entering the contact surface between the limit switch 8 and the threaded seat 6, thereby improving the reliability of the contact.
[0024] Furthermore, in the above technical solution, a screw rod 5 is rotatably installed between the motor base 2 and the tail base 3 and above the base 1 , and a threaded seat 6 is threadedly sleeved on the screw rod 5 , and the screw rod 5 corresponds to the position of the through slot 9 of the base 1 .
[0025] Furthermore, in the above technical solution, a socket 31 is opened at the lower front side of the tailstock 3, one end of the support bar 7 is inserted into the socket 31, and one end of the support bar 7 is fixedly connected to one side of the motor seat 2, which facilitates the installation and disassembly of the support bar 7 and the limit switch 8.
[0026] The double-limit single-axis robot provided by the utility model has the following working process when in use: first, place the base 1 on a stable ground, and then fix the motor base 2 and the tail base 3 on the base 1. Next, install the support bar 7, and ensure that limit switches 8 are respectively provided at both ends. According to the actual application requirements, adjust the position of the limit switch 8 so that it corresponds to the through slot 9 on the base 1, and the bottom of the threaded seat 6 contacts the contact of the limit switch 8 to ensure accurate limit. At the same time, the design of the through slot 9 on the base 1, when foreign particles enter the base 1 during the operation of the robot, they can fall out through the through slot 9, avoiding the foreign matter from adhering to the screw rod 5.
[0027] Start the motor seat 2 to rotate the screw rod 5, and then the threaded seat 6 moves back and forth following the forward and reverse movement of the screw rod 5. The bottom of the threaded seat 6 contacts the contact points of the limit switch 8 at both ends of the support bar 7 to achieve precise control. When the threaded seat 6 moves to the limit position, the robot stops moving. During long-term use, if the contact points of the limit switch 8 are worn, the limit switch 8 can be replaced without affecting the normal operation of the robot.
[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
