Description

Technical Field

[0001] This utility model relates to the field of tap testing technology, and more specifically to a tap testing device. Background Technology

[0002] The tap blank is a cylindrical guide rod. The cylindrical guide rod is first rough-machined by turning and a certain rough grinding allowance is retained. Then it is fine-ground to ensure the diameter and appearance of the cylindrical guide rod. Finally, it is clamped on a gear milling machine to hob the tooth groove and chip groove, thus completing the machining of the tap.

[0003] After the taps are produced, they need to be inspected to ensure that the outer diameter or tooth shape of the taps are within the acceptable range. Currently, the inspection is usually carried out by manually holding the tap to observe whether there are defects in the cutting edge of the tap. Since the cutting edge is evenly distributed in a straight line on the tap and there are many of them, if the taps are produced in large quantities, manual inspection is prone to oversights, which will affect the quality of the taps leaving the factory.

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, a tap testing device includes:

[0031] Support plate 1, on which a conveying unit 2 is provided;

[0032] Clamping member 4 is disposed on conveying unit 2. Clamping member 4 includes clamping block 42 and clamping rod 44 rotatably disposed on clamping block 42. One end of clamping rod 44 is provided with adjusting wheel 43.

[0033] The detection unit 3 is disposed on the support plate 1, and the detection unit 3 includes a support frame 31 and a detection camera 32 disposed on the support frame 31. The camera opening of the detection camera 32 faces the clamping block 42, and the support frame 31 is fixed on the support plate 1.

[0034] The support frame 31 is equipped with a rack 33 that meshes with the adjusting wheel 43.

[0035] Specifically, the conveying unit 2 is provided with two sets of components fixed to the inner side of the support plate 1. The two conveying units 2 operate synchronously via the rotating rod 23. When the tap needs to be inspected, the taps are assembled one by one onto the clamping block 42 and engaged with the clamping rod 44. Then, the conveying unit 2 controls the clamping block 42 to move within the conveying range until it is positioned directly below the inspection camera 32. After the first set of inspection cameras 32 has completed its inspection, the clamping block 42 continues to move. At this time, the rack 33 meshes with the adjusting wheel 43 to control the clamping rod 44 and the tap to rotate synchronously on the clamping block 42, thereby adjusting the inspection angle of the tap. Multiple inspection cameras 32 perform inspections step by step, thereby improving the inspection effect of the tap.

[0036] As a further embodiment of this utility model, a conveying section is provided between the two support plates 1. A loading and unloading area 12 is provided on one side of the conveying section, and a detection unit 3 is provided on the other side. The upper part of the loading and unloading area 12 is for tap feeding, and the lower part is for tap unloading. After the tap is fed, it moves within the conveying section through the conveying unit 2. When it moves to the end, the detection camera 32 in the detection unit 3 will detect the cutting edge of the tap to detect the integrity of the cutting edge of the tap.

[0037] As a further embodiment provided by this utility model, the detection unit 3 is provided with at least four sets. When the rack 33 meshes with the adjusting wheel 43, one rack 33 can drive the adjusting wheel 43 to rotate one-quarter of the circumference. Similarly, the detection unit 3 is provided with four sets, which can effectively detect the four cutting edges arranged on the tap, thereby improving the detection effect of the tap.

[0038] As a further embodiment of this utility model, a semi-circular groove 41 is provided on the clamping block 42, and a clamping rod 44 is fixed to one end of the semi-circular groove 41. An arc-shaped portion 441 facing the semi-circular groove 41 is provided on the clamping rod 44. During the feeding process, the tap will be inserted into the arc-shaped portion 441 along the semi-circular groove 41. Since the arc-shaped portion 441 is made of rubber, the fixing effect of the tap is improved. At the same time, the clamping rod 44 and the tap can rotate synchronously on the clamping block 42. Furthermore, a second bearing 442 is provided at the connection between the clamping rod 44 and the clamping block 42 to improve the rotation effect of the clamping rod 44.

[0039] As a further embodiment of this utility model, the clamping block 42 is provided with a first bracket 45 and a second bracket 46 respectively. The second bracket 46 cooperates with the conveying unit 2. The support plate 1 is provided with a guide frame 11. The first bracket 45 is slidably connected to the guide frame 11. The first bracket 45 and the second bracket 46 are both support members. The first bracket 45 can slide on the guide frame 11, while the second bracket 46 is fixed to the chain 21. The first bracket 45 and the second bracket 46 are used to ensure that the clamping block 42 moves smoothly within the conveying range.

[0040] As a further embodiment of this utility model, a side plate 35 is provided on the support frame 31, and a sliding groove 351 is provided on the side plate 35. A slide 34 that engages with the detection camera 32 is provided in the sliding groove 351. The side plate 35 serves to support the slide 34. The slide 34 can slide in the sliding groove 351, thereby adjusting the position of the detection camera 32, so that the detection device can adapt to taps of different specifications.

[0041] As a further embodiment of this utility model, the slide 34 is provided with an aperture 38 that cooperates with the detection camera 32. In order to improve the detection accuracy of the detection camera 32, the aperture 38 is installed on the slide 34. The distance between the aperture 38 and the detection camera 32 is adjustable, so as to reduce the error during the operation of the detection camera 32 and improve the detection accuracy of the tap.

[0042] As a further embodiment of this utility model, a fixing block 36 is provided on the support frame 31, and a spring 37 is provided inside the fixing block 36 to push the rack 33. The elastic force of the spring 37 is used to push the rack 33 to always slide downward on the fixing block 36, so as to ensure that the adjusting wheel 43 in the clamping member 4 can accurately contact the rack 33 during the conveying process, so that the clamping rod 44 can rotate smoothly to adjust the angle of the tap during operation.

[0043] As a further embodiment of this utility model, the conveying unit 2 includes a motor 25, a transmission wheel 22, and a chain 21 disposed on the transmission wheel 22. The output end of the motor 25 is provided with a rotating rod 23, which engages with the transmission wheel 22. The motor 25 is fixed to one side of the support plate 1. The model of the motor 25 is MHMF042L1U4-1116. The rotating rod 23 is rotated by the motor 25. At this time, the transmission wheel 22 rotates synchronously under the drive of the rotating rod 23. Then, the chain 21 drives the clamping block 42 to gradually approach the detection camera 32. The detection camera 32 takes pictures of the tap from various angles to ensure that the cutting edge of the tap remains intact.

[0044] As a further embodiment of this utility model, a first bearing 24 that cooperates with the rotating rod 23 is provided on the support plate 1. At least two sets of the first bearing 24 are provided and installed on the support plate 1 to support and assist the rotation of the rotating rod 23, thereby improving the rotational stability of the rotating rod 23.

[0045] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
