Description

Technical Field

[0001] This invention relates to the field of tensioner production equipment technology, and more specifically, to a tensioner assembly device and assembly method. Background Technology

[0002] In existing technology, the tensioning wheel includes a rotatable plastic wheel, which needs to be bolted to an extension plate of the tensioning wheel body. Before fixing the plastic wheel to the extension plate, the mounting surface of the extension plate where the plastic wheel is mounted needs to be flat to ensure that the plastic wheel will not rub against the mounting surface after installation. The existing flatness measurement method uses a detection head that can move up and down. The detection head needs to descend to contact the mounting surface. The detection head has at least three flatness measurement terminals to measure the flatness of a plane. The display error value is used to determine whether the plane is qualified. However, during the test, the main body of the tensioning wheel needs to be placed in a tooling fixture. If there is an offset between the main body of the tensioning wheel and the tooling fixture, it will cause an angular offset between the mounting surface and the detection head, resulting in a large and inaccurate flatness measurement error. Therefore, a technical solution is needed to solve the above problems. Summary of the Invention

[0020] 1. This invention enables the measuring end face to be close to the measuring component. The lower end face of the first mounting plate is set parallel to the upper end face of the support plate, so that when the support plate drives the tension wheel to approach the measuring component, the measuring end face detection error is smaller. The first side plate and the second side plate are designed separately. When the support plate drives the movable seat to move, a gap is generated between the lower end face of the tension wheel body and the placement plane of the tension wheel on the movable seat. This can eliminate the error caused by the contact between the lower end face of the tension wheel body and the movable seat, reduce the impact on the measuring end face detection, and make the measuring result more accurate.

Detailed Implementation

[0033] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1 , Figure 2 As shown, this embodiment discloses a tensioning wheel assembly device for detecting a tensioning wheel 4. The tensioning wheel 4 includes a main body 41 and an extension plate 42. The extension plate 42 includes a flat end face 421, which is the position for installing a plastic wheel. The device includes a flatness measuring device 1, a screw-driving device 2, a receiving component 3, and a frame 5. The flatness measuring device 1, screw-driving device 2, and receiving component 3 are installed on the upper end face of the frame 5. The flatness measuring device 1, screw-driving device 2, and receiving component 3 are arranged horizontally, with the receiving component 3 located between the flatness measuring device 1 and the screw-driving device 2. Between them, the leveling device 1 is set at an angle, and the receiving component 3 includes a third mounting plate 31. The third mounting plate 31 is provided with a first receiving groove 32 and a second receiving groove 33. The first receiving groove 32 and the second receiving groove 33 are arranged vertically. A part of the first receiving groove 32 and the second receiving groove 33 extends into the range of the leveling device 1 and is consistent with the tilt angle of the leveling device 1, which makes it more convenient to receive the tensioning roller 4 sent out by the leveling device 1. The first receiving groove 32 can receive qualified tensioning rollers 4, and the second receiving groove 33 can receive unqualified tensioning rollers 4.

[0035] like Figure 3 As shown, the leveling device 1 includes a back plate 11, a front plate 12, a lifting device 13, a leveling assembly 14, and a movable seat 15. The back plate 11 is fixedly mounted on the frame 5 by mounting columns, and the front plate 12 is fixedly mounted on the back plate 11. The back plate 11 and the front plate 12 are spaced apart. The upper ends of both the back plate 11 and the front plate 12 are inclined towards the receiving assembly 3 to facilitate the detachment of the leveling device 1 by the weight of the tensioning wheel 4 during the subsequent sorting process. The front plate 12 is provided with a sliding groove 121. The lifting device 13 includes a support plate 131 and a driving device 132. The driving device 132 can drive the support plate 131. 1. Slide along the sliding groove 121. The driving device 132 is an electric telescopic device. The front plate 12 is provided with a first mounting plate 122 and a second mounting plate 124. The first mounting plate 122 is located on the front end face of the front plate 12, and the second mounting plate 124 is located on the rear end face of the front plate 12. The driving device 132 is fixedly installed on the second mounting plate 124. The lower end of the telescopic rod of the driving device 132 is connected to the support plate 131. The lower end face of the first mounting plate 122 is parallel to the upper end face of the support plate 131, so that when the support plate 131 drives the tension wheel 4 to approach the leveling component 14, the detection error of the leveling end face 421 can be smaller.

[0036] like Figure 4 , Figure 5 As shown, the leveling component 14 is mounted on the first mounting plate 122. The leveling component 14 is located at the upper end of the sliding groove 121. The leveling component 14 includes three leveling terminals 141 and a mounting base 142. The mounting base 142 has three second mounting holes 1421. The mounting base 142 mounts three movable members 143. At least a portion of the movable members 143 extends out of the lower end face of the mounting base 142, and at least a portion of the movable members 143 is located within the second mounting holes 1421. A first spring 144 is installed within the second mounting holes 1421. One leveling terminal 141 is installed at the upper end of each second mounting hole 1421. The movable member 143 can move up and down along the second mounting hole 1421. The lower end of the measuring terminal 141 is provided with a detection end 1411. The upper end of the movable member 143 can approach or move away from the detection end 1411. When the measuring end face 421 contacts the lower end of the movable member 143, the movable member 143 is pushed upward by the measuring end face 421 until the upper end of the movable member 143 contacts the detection end 1411 of the measuring terminal 141. The control system connected to the measuring terminal 141 can receive the signal and process it to obtain the time difference between the contact between the three measuring terminals 141 and the movable member 143, thereby determining whether the measured end face 421 being tested is qualified.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the front plate 12 is provided with a slide rail 123, which is located on the side of the sliding groove 121 near the receiving component 3. The movable seat 15 is slidably installed on the slide rail 123. The support plate 131 is provided with a first side plate 133, and the movable seat 15 is provided with a second side plate 151. At least a part of the first side plate 133 is located below the second side plate 151. The first side plate 133 can drive the second side plate 151 to move. The support plate 131 can drive the movable seat 15 to move. When the support plate 131 moves closer to the leveling component 14, the first side plate 133 abuts against the second side plate 151, thereby driving the movable seat 15 to move upward. When the support plate 131 moves away from the leveling component 14, the movable seat 15 moves downward under the influence of gravity. The movable seat 15 can hold the tensioning wheel 4. The leveling end face 421 is located within the range of the extension plate 42. The support plate 131 is used to support the extension plate 42.

[0038] like Figure 4 , Figure 6As shown, the lifting device 13 includes a limiting member 18, which is mounted on a support plate 131. The support plate 131 has a first through hole 134 and a first mounting hole 135. The limiting member 18 includes a mounting tube 181 and a limiting post 182. The mounting tube 181 passes through the first through hole 134, and the limiting post 182 passes through the first mounting hole 135. A third spring 1822 is installed in the first mounting hole 135. The limiting post 182 has a ring plate 1821 located in the first mounting hole 135. The upper end of the third spring 1822 abuts against the lower end face of the ring plate 1821. The extension plate 42 has a second through hole 422, and the first through hole 134 is aligned with the second through hole 422. When the support plate 131 is in the first position, at least a part of the mounting tube 181... The mounting tube 181 is located inside the second through hole 422. When the support plate 131 is in the second position, the mounting tube 181 leaves the second through hole 422. When the tension wheel 4 is placed on the movable seat 15, the lower end face of the extension plate 42 does not contact the upper end face of the support plate 131. The mounting tube 181 passes through the second through hole 422 to position the extension plate 42. When the drive device 132 drives the support plate 131 to move upward, when the first side plate 133 abuts against the second side plate 151, a gap is generated between the lower end face of the body 41 of the tension wheel 4 and the placement plane of the movable seat 15 where the tension wheel 4 is placed. This can eliminate the error caused by the contact between the lower end face of the body 41 of the tension wheel 4 and the movable seat 15, reduce the impact on the detection of the flat end face 421, and make the flatness measurement result more accurate.

[0039] More preferably, the movable seat 15 is provided with a stop block 152, which is located on the side of the movable seat 15 near the support plate 131. The stop block 152 is provided with a stop surface 153, which is arc-shaped and abuts against the outer wall of the main body 41. The stop surface 153 of the movable seat 15 supports the main body 41 and plays the role of positioning and limiting the tension wheel 4.

[0040] like Figure 4 , Figure 5 , Figure 6 As shown, a second spring 1811 is installed inside the mounting tube 181, and a ball bearing 1812 is installed in the mounting tube 181. The upper end of the second spring 1811 abuts against the ball bearing 1812. At least a portion of the ball bearing 1812 is located inside the mounting tube 181. The ball bearing 1812 can move up and down along the mounting tube 181. When the measuring end face 421 abuts against the movable part 143 and contacts the measuring assembly 14 to perform measuring calculation, the limiting post 182 abuts against the lower end face of the first mounting plate 122, and the mounting tube 181 leaves the second through hole 422. Since the entire measuring device 1 is in an inclined state, the ball bearing 1812 located in the second through hole 422 can play a certain limiting role on the extension plate 42, and can cooperate with the elastic pressure of the movable part 143 to clamp it, preventing the tensioning wheel 4 from accidentally dislodging during measuring.

[0041] like Figure 7 , Figure 8 , Figure 9 As shown, the support plate 131 includes a first position, a second position, and a third position. When the support plate 131 is in the first position, the tensioning wheel 4 can be placed on the movable seat 15 and the support plate 131. At this time, the support plate 131 is in its initial position, and the tensioning wheel 4 is positioned on the movable seat 15 and the support plate 131. The driving device 132 drives the support plate 131 to move to the second position. When the support plate 131 is in the second position, the flat end face 421 contacts the movable part 143. The movable part 143 is pressed upward to contact the detection end 1411 of the flat end 141. At this time, the movable part... The seat 15 is aligned with the first receiving slot 32. The front plate 12 is equipped with a cylinder 16, and the cylinder 16 is equipped with a push plate 161. When the support plate 131 is in the second position, the push plate 161 can push the extension plate 42 out of the support plate 131. When the control system determines that the flat end face 421 is qualified, the cylinder 16 controls the push plate 161 to extend. The push plate 161 pushes the extension plate 42 toward the movable seat 15, so that the extension plate 42 leaves the support plate 131. The qualified tensioning wheel 4 falls into the first receiving slot 32 of the receiving component 3 under the action of gravity.

[0042] The front plate 12 is mounted on the base plate 17, which is located at the lower end of the slide rail 123. The upper end of the base plate 17 is provided with a top rod 171. When the support plate 131 is in the first and third positions, the upper end of the top rod 171 abuts against the lower end of the movable seat 15. When the control system determines that the flat end face 421 is unqualified, the drive device 132 drives the support plate 131 to move from the second position to the third position. During this process, the top rod 171 abuts against the movable seat 15, and the first side plate 133 separates from the second side plate 151. At this time, the second mounting tube 181 leaves the second through hole 422, and the tension wheel 4 slides towards the second receiving groove 33 of the receiving component 3 under the action of gravity. The main body 41 leaves the movable seat 15, and the unqualified tension wheel 4 can enter the second receiving groove 33, forming a classification function after the tension wheel 4 is detected.

[0043] like Figure 1 , Figure 2 , Figure 10As shown, the screw-driving device 2 includes a screw-driving assembly 21 and a clamp 22. The clamp 22 is located below the screw-driving assembly 21 and can fix the tension wheel 4. The screw-driving assembly 21 includes a screwdriver 211 that can move up and down. The tip of the screwdriver 211 is concentrically set with the second through hole 422. The clamp 22 includes a placement seat 221 and a connecting plate 222. The placement seat 221 is fixedly installed on the connecting plate 222, and the connecting plate 222 is fixedly installed on the frame 5. The placement seat 221 includes a limiting plate 2211 and a limiting arc surface 2212. The inner wall of 1 can abut against the side wall of the extension plate 42, the limiting arc surface 2212 abuts against the side wall of the main body 41, the limiting plate 2211 positions the end of the extension plate 42, the limiting arc surface 2212 positions the main body 41, the connecting plate 222 is equipped with a clamping block 223, the clamping block 223 can approach or move away from the placement seat 221, the connecting plate 222 is provided with a spring, the spring can apply a continuous clamping force to the clamping block 223 on the tensioning wheel 4, the clamping block 223 can abut against the side wall of the main body 41, and can fix the tensioning wheel 4 placed on the clamp 22.

[0044] This embodiment also discloses a tensioning wheel assembly method, which uses the above-mentioned tensioning wheel assembly device and includes the following steps:

[0045] S1. Loading: Place the tensioning wheel 4 in the leveling device 1, place the main body 41 of the tensioning wheel 4 on the movable seat 15, and place the extension plate 42 of the tensioning wheel 4 on the support plate 131, so that the mounting tube 181 on the support plate 131 passes through the second through hole 422 of the extension plate 42.

[0046] S2, Leveling: Start the drive device 132. The drive device 132 drives the support plate 131 to approach the leveling component 14. The support plate 131 drives the movable seat 15 to move at the same time. The leveling end face 421 of the extension plate 42 contacts the leveling terminal 141 of the leveling component 14 for detection. The control system connected to the leveling terminal 141 judges whether the error of the leveling end face 421 is within the standard range.

[0047] S3. Sorting: When the control system determines that the flat end face 421 is qualified, the cylinder 16 controls the push plate 161 to extend. The push plate 161 pushes the extension plate 42 towards the movable seat 15, causing the extension plate 42 to leave the support plate 131. The tension wheel 4 falls into the first receiving groove 32 of the receiving component 3 under the action of gravity. The drive device 132 drives the support plate 131 back to the initial position, and the movable seat 15 and the support plate 131 reset simultaneously. When the control system determines that the flat end face 421 is unqualified, the drive device 132 drives the support plate... As the support plate 131 moves away from the leveling device 1, the movable seat 15 moves away from the leveling device 1 and is held in place by the top rod 171. The first side plate 133 and the second side plate 151 separate. The support plate 131 continues to move away from the leveling device 1. The second mounting tube 181 leaves the second through hole 422. The main body 41 leaves the movable seat 15. The tension wheel 4 slides into the second receiving groove 33 of the receiving component 3 under the action of gravity. The driving device 132 drives the support plate 131 back to the initial position. The movable seat 15 and the support plate 131 reset simultaneously.

[0048] S4. Assembly and rework: Take the qualified tensioning wheel 4 in the first receiving slot 32 into the clamp 22 of the screw-driving device 2, assemble the nut, plastic wheel, bolt and tensioning wheel 4, lower the screwdriver 211 of the screw-driving assembly 21 to tighten the bolt, and install the plastic wheel on the extension plate 42; collect the unqualified tensioning wheel 4 in the second receiving slot 33 and send it for rework and repair.
