[0025] The utility model provides a joint nut drilling fixture, including a fixed plate 101, two slides 102, a workbench 103 and a transmission mechanism, wherein the transmission mechanism includes two first screw rods 111, a belt body 112, a protective cover 113 and a motor 114. The above-mentioned scheme solves the technical problem that the guide rod in the above-mentioned structure can only play a guiding role but cannot effectively support the fixed plate 101, so that when the load is too large, the friction between the fixed plate 101 and the guide rod will increase, thereby making the motor 114 prone to overload operation.

[0026] According to this specific embodiment, the fixed plate 101 has a convex groove 104, and two convex blocks 105 and a bidirectional screw 106 are arranged in the convex groove 104. A moving block 107 is arranged on the convex block 105, and an insert block 108 is inserted in the moving block 107. An arc-shaped clamping plate 109 is arranged at one end of the insert block 108 away from the moving block 107. Threaded blocks 110 are arranged at both ends of the fixed plate 101. The fixed plate 101 is slidably connected with the corresponding slide seat 102 and is located between the two slide seats 102, and the threaded block 110 is located in the slide seat 102. The two slides 102 are respectively fixedly connected to the workbench 103 and are located above the workbench 103. The two convex blocks 105 are respectively threadedly connected to the bidirectional screw 106 and are sleeved on the bidirectional screw 106. By placing the workpiece between the two arc-shaped clamping plates 109 and then rotating the bidirectional screw 106, the two convex blocks 105 are moved in a direction approaching each other under the action of the bidirectional screw 106, thereby clamping and fixing the workpiece. In addition, the arrangement of the insert block 108 can facilitate the replacement of the arc-shaped clamping plates 109 required for different models.

[0027] Among them, a pulley 115 is provided on the first screw rod 111, and a polygonal sleeve 116 is provided at one end of one of the first screw rods 111, and a polygonal rod 117 is provided at the output end of the motor 114, and the two first screw rods 111 are respectively rotatably connected with the corresponding slide seat 102 through bearings, and are located in the slide seat 102 and extend to the bottom of the workbench 103, and the two first screw rods 111 are also respectively threadedly connected with the corresponding thread block 110 and are located in the thread block 110, the belt body 112 is respectively connected with the pulley 115 in transmission and is covered on the outside of the two pulleys 115, and the protective cover 113 is fixedly connected with the workbench 103 and is located on the workbench 1 03, and the belt body 112 and the two pulleys 115 are both located in the protective cover 113, the motor 114 is fixedly connected to the protective cover 113 and is located below the protective cover 113, the polygonal rod 117 is plugged with the polygonal sleeve 116 and is located in the polygonal sleeve 116, and the polygonal sleeve 116 passes through the protective cover 113, and the first screw rods 111 are arranged at both ends of the slide 102, and the pulleys 115 and the belt body 112 are arranged, so that the two first screw rods 111 can support the fixed plate 101 at the same time, thereby effectively avoiding the problem that the fixed plate 101 is supported on only one side, which causes the motor 114 to be easily overloaded.

[0028] Secondly, the inner wall of the belt body 112 is provided with a plurality of latch teeth 118, the outer side of the pulley 115 has a plurality of latch grooves 119, and the latch teeth 118 are adapted to each other. The arrangement of the latch teeth 118 and the latch grooves 119 can ensure that the two first screws 111 can rotate simultaneously, so that slipping will not occur.

[0029] Again, a buffer pad 120 is provided in the arc-shaped clamping plate 109 , and the buffer pad 120 can be used to protect the surface of the workpiece and improve the anti-slip property.

[0030] When the height of the fixed plate 101 is adjusted by using the utility model, the motor 114 is started so that the motor 114 transmits one of the first screw rods 111 under the action of the polygonal rod 117 and the polygonal sleeve 116, and the other first screw rod 111 rotates synchronously under the action of the pulley 115 and the belt body 112, and the fixed plate 101 moves upward under the action of the two threaded blocks 110, thereby completing the height adjustment. In this way, the problem that the guide rod in the above structure can only play a guiding role but cannot effectively support the fixed plate 101 is solved, so that when the load is too large, the friction between the fixed plate 101 and the guide rod will increase, and the motor 114 will be prone to overload operation is solved.

The setting of the second screw rod 202 can facilitate the subsequent replacement of the damaged anti-slip pad 201.

[0036] Secondly, the pulling handle 204 is fixedly connected to the fastening rod 206 and is located at one end of the fastening rod 206. The spring 205 is welded to the pulling handle 204 and is located below the pulling handle 204. The spring 205 is also welded to the moving block 107 and is located above the moving block 107. The spring 205 is sleeved on the fastening rod 206. The fastening rod 206 is plugged into the moving block 107 and is located inside the moving block 107. It also passes through the plug block 107. 08, by pulling the handle, the handle will pull the fastening rod 206 out of the plug block 108, then the arc splint 109 can be replaced, and then the plug block 108 on the appropriate arc splint 109 is inserted into the moving block 107, and finally the pulling handle 204 is loosened, and the fastening rod 206 is automatically inserted into the moving block 107 under the action of the spring 205, and passes through the plug block 108, thereby fixing the arc splint 109.
