[0031] Example

[0032] See also Figure 1 , 12 The present invention provides a technical solution: it includes an inspection base plate 1, the top of the inspection base plate 1 is fixedly connected with a front fork frame 2, a cross fork frame 3 and a positioning frame 4, the cross fork frame 3 is provided with two positioning columns 5 and a center column 6 fixedly installed in the positioning frame 4, and the center column 6 is slidably connected with a front pressure plate 7 outside.

[0033] Insert the wrist body 34 to be tested on the positioning frame 4 according to the positions of the positioning plug column 5 and the central plug column 6, and at the same time, the protruding cylinder at the front end is placed on the front fork frame 2, and the cylinders on both sides are placed on the cross fork frame 3, and then insert the positioning plug column 5, and put the front pressure plate 7 outside the central plug column 6 and press the front end surface of the wrist body 34 on the positioning frame 4 to fix the wrist body 34 on the inspection base plate 1, and then use a detection ruler or other tools to detect the flushness and standard height ( Fig.12 Only two measuring surfaces are marked in the figure), the wrist body 34 can be detected whether it is qualified, the inspection is relatively simple, and multiple surfaces and specific positions can be inspected at one time on the inspection base plate 1, which is more efficient, saves time and improves efficiency, and the fixed inspection is more accurate. The frame structure is simple, the additional cost is small, it is more flexible, easy to put into use, and convenient to unify the measurement standards, avoid the subjective influence of different people's measurements, and provide a good foundation for the subsequent production and assembly of subsequent robot components, avoid the circulation of defective parts causing rework or assembly abnormal noise, speed up efficiency, and help improve the overall quality.

[0034] The positioning pin 5 and the center pin 6 are threadedly connected to the positioning frame 4, and the front end of the positioning pin 5 is truncated cone-shaped, which has a guiding function and facilitates the positioning and insertion of the wrist body 34.

[0035] Example

[0036] See also Figure 1-12Among them, the front end of the central plug column 6 is fixedly connected to the guide square column 8, the front pressure plate 7 is slidably connected to the outside of the guide square column 8, and the two ends of the front pressure plate 7 are provided with inner sliding windows 9. The inner sliding windows 9 are slidably connected to the extension pressure plate 10. The extension pressure plate 10 is flush with the front and rear side surfaces of the front pressure plate 7. The flush surface can have a larger contact surface when fixing the wrist body 34, which is more stable and not easy to tilt.

[0037] Among them, the guide square column 8 is provided with an upper slide groove 11 and a lower slide groove 12, between which is an intermediate strip 13, and on both sides of the intermediate strip 13 are side racks 14, and on both sides of the middle of the front pressing plate 7 are provided with mounting grooves 15, in which an extension gear 16 is rotatably connected, and an extension rack 17 is fixedly connected to the inner side of the extension pressing plate 10, and the extension racks 17 of the extension pressing plates 10 on both sides are staggered up and down and extend into the upper slide groove 11 and the lower slide groove 12 one by one to slide and cooperate with them, and the extension gear 16 and the extension rack 17 on the same side are meshed. The coordination of the gear and rack enables the front pressing plate 7 to push out the extension pressing plate 10 as quickly and as much as possible when moving, thereby playing the role of front end positioning in time.

[0038] Among them, a mounting bar 18 is fixedly connected to the front side of the front pressure plate 7, and the mounting bar 18 is located on both sides of the guide square column 8. An inner clamping frame 19 and an outer clamping frame 20 are slidably connected inside the mounting bar 18. The inner clamping frame 19 and the outer clamping frame 20 are arranged front and back and the outer ends are fixedly connected with a pressure plate 21 and the inner ends are plugged into the side rack 14. A positioning spring 22 is provided between the pressure plate 21 and the mounting bar 18.

[0039] The wrist body 34 to be tested is placed on the inspection base plate 1 in the same manner as in Example 1. The difference is that the center of the wrist body 34 can directly pass through the front pressure plate 7. After being placed, the inner side clamping frame 19 and the inner side of the outer clamping frame 20 can be driven to move away from each other and leave the side rack 14 by manually squeezing the training pressure plate 21 inward, so that the front pressure plate 7 can move relative to the guide square column 8. At this time, the front pressure plate 7 is pushed inward to press the wrist body 34 onto the positioning frame 4. In this process, the front pressure plate 7 moves inward, and the extension gear 16 also moves together. With the cooperation of the side rack 14, the extension gear 16 rotates, thereby driving the extension rack 17 meshing with it to move outward, thereby pushing the extension pressure plate 10 outward, and then the extension pressure plate 10 presses the front end surface of the wrist body 34, so that the wrist body 34 is easy to put into place and fix simply and conveniently; through the cooperation of the extension gear 16 and the extension rack 17, the extension pressure plate 10 can respond and extend in time, which is relatively fast. At the same time, the front pressure plate 7 moves while the extension pressure plate 10 extends, which saves time and does not require separate adjustment.

[0040] After adjusting the position of the front pressure plate 7, release the pressure plate 21, and under the action of the positioning spring 22, push the inner clamp frame 19 and the outer clamp frame 20 outward to return to their original positions, so that the inner sides of the two are clamped on the side rack 14 and plugged into the side rack 14, so that the front clamp plate 7 cannot move, and the positioning of the front clamp plate 7 is achieved, which is relatively simple and quick.

[0041] Among them, mounting plates 23 are fixedly connected on both sides of the cross fork frame 3, and the mounting plates 23 on the opposite sides of the cross fork frame 3 are jointly rotatably connected with a synchronization rod 24, and both ends of the synchronization rod 24 are fixedly connected with a pressure rod 25; the pressure rod 25 at both ends connected by the synchronization rod 24 can simultaneously assist in fixing the two ends of the wrist body 34, thereby reducing the number of operating steps.

[0042] Among them, an open groove 26 is opened in the middle of the pressure rod 25, and inner sliding grooves 27 are opened on both sides of the open groove 26 in the middle of the pressure rod 25 at both ends of the synchronization rod 24 on one side, and a moving shaft 28 is slidably connected in the inner sliding groove 27, and a round-headed long-hole rod 29 is slidably sleeved outside the moving shaft 28, and clamping plates 30 are slidably connected on both sides of the round-headed long-hole rod 29.

[0043] Among them, a solid plate 31 is fixedly connected to the middle part of the clamping plate 30, a fixing bolt 32 is installed in the middle of the round-headed long-hole rod 29, and a double-headed cam 33 is fixedly connected to the outer side of the fixing bolt 32. The double-headed cam 33 is located between the solid plates 31 and contacts the inner side of the solid plates 31. The fixing bolt 32 is used to open the clamping plate 30 outward to tighten and fix the round-headed long-hole rod 29 in the open groove 26 of the pressure rods 25 on both sides.

[0044] After the wrist body 34 is placed, in order to make the wrist body 34 more stable during measurement, the pressure rod 25 is rotated inward at the same time to make it rest on the cylinders on both sides of the wrist body 34 in an eight-shaped shape, and the internal round-headed long-hole rod 29 automatically slides out and falls into the open groove 26 of the pressure rod 25 on the other side. At this time, the round-headed long-hole rod 29 rests on the top surface of the cylinders on both sides of the wrist body 34, and then the fixing bolt 32 is rotated. When it rotates, the double-headed cam 33 rotates so that its protrusion pushes the solid plate 31 outward, and then pushes the clamping sheet 30 outward, thereby tightening it. The pressure rods 25 on both sides are in the open grooves 26, thereby fixing the round-headed long-hole rods 29. At the same time, the pressure rods 25 on both sides cannot move relative to the round-headed long-hole rods 29, thereby fixing the pressure rods 25, so that the pressure rods 25 and the round-headed long-hole rods 29 form a semi-enclosed structure to press the cylinders on both sides onto the cross fork frame 3, thereby further fixing the wrist body 34, which is convenient for more accurate detection. At the same time, the fixing process is relatively simple and reliable. This fixing method is more flexible to use and can be fixed at any position. It is suitable for auxiliary fixation of wrist bodies 34 of different sizes.
