Description

TECHNICAL FIELD

[0001] The application relates to the field of part detection, in particular to a bending precision detection equipment for a high-tooth plate. BACKGROUND

[0002] The high-tooth plate is one of the core components in a high-tooth module of an automobile seat, and can realize the adjustment of the height of the automobile seat, meet the comfort requirements of passengers of different heights and body shapes on the seat, and improve the applicability and user experience of the automobile seat.

[0003] In the production process of the high-tooth plate, there is a bending process, which aims to realize the cooperation with other parts. However, in order to ensure the precision after bending, the angle of bending needs to be detected, so as to improve the product qualification rate of the tooth plate.

[0004] The traditional bending angle detection method is to directly measure the distance between the two opposite sides of the bending part by using a vernier caliper, so as to observe whether the distance size is within the range. Although the detection accuracy of this detection method is high, the efficiency is low, and it is not suitable for large-scale detection, which has obvious defects. CONTENT OF THE INVENTION

[0005] In order to improve the detection efficiency, the application provides a bending precision detection equipment for a high-tooth plate.

[0006] The bending precision detection equipment for a high-tooth plate provided by the application adopts the following technical scheme:

[0007] The bending precision detection equipment for a high-tooth plate comprises a detection base and a go-no-go gauge. The top of the detection base is arranged with a detection surface with a height lower than the top surface. The high-tooth plate is placed at the highest position of the detection base, and the bending part of the high-tooth plate is located above the detection surface and has a distance therebetween.

[0008] By adopting the above technical scheme, the worker manually places the high-tooth plate to be detected on the detection base, and then holds the go-no-go gauge, so that the go gauge end and the stop gauge end pass through the distance between the bending part and the detection surface in turn. If the go gauge end passes and the stop gauge end cannot pass, the product is qualified; if both the go gauge end and the stop gauge end pass or cannot pass, the product is unqualified. By adopting the above method, whether the bending angle of the bending part of the high-tooth plate is accurate is manually detected, which is convenient to operate, improves the detection efficiency, and is suitable for large-scale detection.

[0009] Optionally, the top of the detection base is arranged with a plurality of positioning columns for abutting against the side edges of the high-tooth plate.

[0010] By adopting the above technical scheme, the plurality of positioning columns cooperate to position the placement position of the high-tooth plate, and ensure the commonality of the bending angle detection of different high-tooth plates.

[0011] Optionally, the detection base is arranged with a motor and a start-stop button connected to the control system, a sleeve ring is rotatably sleeved on the output shaft of the motor, and a turning gauge and a turning stop gauge are arranged on the circumferential outer wall of the sleeve ring.

[0012] By adopting the above technical scheme, when the high-tooth plate is placed on the detection base, the worker manually presses the start-stop button, the control system realizes power-on of the motor, the output shaft of the motor drives the sleeve ring to rotate through friction, and the sleeve ring drives the turning gauge and the turning stop gauge to rotate, so as to observe whether the turning gauge and the turning stop gauge can pass between the bending part of the high-tooth plate and the detection surface. The electric mode is adopted to replace the manual switching of the detection end by the worker, thereby improving the operation convenience and enhancing the detection efficiency.

[0013] Optionally, the detection base is arranged with a fixing pin, and an elastic pull belt is connected between the fixing pin and the circumferential outer wall of the sleeve ring.

[0014] By adopting the above technical scheme, when the output shaft of the motor drives the sleeve ring to rotate, the sleeve ring first stretches the elastic pull belt to the maximum stretching limit, and then the output shaft of the motor is idled and the sleeve ring is kept stationary. After the motor is powered off, the elastic pull belt restores the deformation, so as to drive the output shaft of the motor to rotate reversely and reset, so that the turning gauge and the turning stop gauge are away from the high-tooth plate, thereby facilitating the taking and placing of the high-tooth plate and improving the operation convenience.

[0015] Optionally, the detection base is arranged with a fixing pin, and an elastic pull belt is connected between the fixing pin and the circumferential outer wall of the sleeve ring.

[0016] By adopting the above technical scheme, when the motor is damaged, the worker can disassemble the mounting block, so as to facilitate the manual detection of the worker by using the turning gauge and the turning stop gauge.

[0017] Optionally, the mounting block is bolted to the detection base.

[0018] By adopting the above technical scheme, the bolted connection is relatively convenient to disassemble and assemble.

[0019] Optionally, a mounting groove is vertically formed at the edge of the detection base, the mounting groove is open at the top and closed at the bottom, the mounting block extends into the mounting groove and is in sliding fit with the mounting groove, and the cross sections of the mounting block and the mounting groove in the sliding fit are dovetail-shaped.

[0020] By adopting the above technical scheme, the mounting block and the mounting groove are in plug-in fit, which is convenient to disassemble and assemble.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. The worker manually places the high pitch gear plate to be detected on the detection base, and then holds the go-no-go gauge, so that the go gauge end and the no-go gauge end pass through the space between the bending part and the detection surface in turn. If the go gauge end passes and the no-go gauge end cannot pass, the product is qualified; if both the go gauge end and the no-go gauge end pass or cannot pass, the product is unqualified. In the above manner, the bending angle of the bending part of the high pitch gear plate is manually detected to determine whether it is accurate, which is convenient to operate, improves the detection efficiency, and is suitable for large batch detection;

[0023] 2. When the high pitch gear plate is placed on the detection base, the worker manually presses the start-stop button, the control system controls the motor to be powered on, the output shaft of the motor drives the sleeve ring to rotate through friction, and the sleeve ring drives the rotating go gauge and the rotating no-go gauge to rotate, so as to observe whether the rotating go gauge and the rotating no-go gauge can pass through the space between the bending part of the high pitch gear plate and the detection surface. The electrically driven manner is used to replace the manual switching of the detection end by the worker, which improves the operation convenience and enhances the detection efficiency;

[0024] 3. When the output shaft of the motor drives the sleeve ring to rotate, the sleeve first stretches the elastic pull belt, and when the stretching reaches the maximum limit, the output shaft of the motor idles and the sleeve ring remains stationary. After the motor is powered off, the elastic pull belt restores the deformation, so as to drive the output shaft of the motor to rotate in the opposite direction through the sleeve ring to reset, so that the rotating go gauge and the rotating no-go gauge move away from the high pitch gear plate, which facilitates the taking and placing of the high pitch gear plate and improves the operation convenience.

[0029] The following will be described in detail with reference to the accompanying drawings Figures 1-3 The present application will be further described in detail.

[0030] Embodiments of the present application disclose a bending precision detection device for a high pitch gear plate.

[0031] Embodiment 1

[0032] Reference Figure 1The application discloses a bending precision detection device for high-pitch toothed plate.

[0033] When the worker places the high-pitch toothed plate on the highest position of the detection base 1, the bending position of the high-pitch toothed plate is above the detection surface 101 and has a spacing therebetween.

[0034] With reference to Figure 1 The go-no-go gauge 2 directly adopts a special detection gauge in the automobile field in the prior art, and comprises a go gauge end and a no-go gauge end, both of which are in a cylindrical shape, and the diameter of the go gauge end is smaller than that of the no-go gauge end.

[0035] With reference to Figure 1 After the worker places the high-pitch toothed plate on the detection base 1, the worker holds the go-no-go gauge 2 and sequentially passes the go gauge end and the no-go gauge end of the go-no-go gauge 2 through the spacing between the bending position of the high-pitch toothed plate and the detection surface 101.

[0036] If the go gauge end passes through but the no-go gauge end cannot pass through, the product is qualified;

[0037] If both the go gauge end and the no-go gauge end pass through or both cannot pass through, the product is unqualified.

[0038] With reference to Figure 1 The top of the detection base 1 is inserted and matched with a plurality of vertical positioning columns 3, the positioning columns 3 are used for abutting the side edges of the high-pitch toothed plate, so that the placement position of the high-pitch toothed plate on the detection base 1 is positioned, and the commonality of the detection of the bending angle of different high-pitch toothed plates in the same batch is improved.

[0039] The implementation principle of the embodiment 1 is that after the worker places the high-pitch toothed plate on the detection base 1, the worker holds the go-no-go gauge 2 and sequentially passes the go gauge end and the no-go gauge end of the go-no-go gauge 2 through the spacing between the bending position of the high-pitch toothed plate and the detection surface 101. If the go gauge end passes through but the no-go gauge end cannot pass through, the product is qualified; if both the go gauge end and the no-go gauge end pass through or both cannot pass through, the product is unqualified.

[0040] Embodiment 2

[0041] With reference to Figure 2 The difference between the embodiment and the embodiment 1 is that a mounting block 11 is detachably connected beside the detection base 1, the top surface of the mounting block 11 is level with the detection surface 101. A motor (not shown in the figure) and a start-stop button (not shown in the figure) electrically connected to a control system are bolted on the mounting block 11, and the start-stop button is used for controlling the start and stop of the motor.

[0042] With reference to Figure 2 The detection base 1 is further inserted and matched with a vertical fixing pin 9, and an elastic pull belt 10 is arranged between the fixing pin 9 and the circumferential outer wall of the sleeve ring 6.

[0043] The output shaft of the motor is sleeved with a collar 6, and a perimeter transit gauge 7 and a perimeter stop gauge 8 are mounted on the circumferential outer wall of the collar 6, and the perimeter transit gauge 7 and the perimeter stop gauge 8 are of the same height.

[0044] Referring to Figure 2 When the worker places the high-toothed plate on the detection base 1, the start-stop button is pressed to energize the motor, and the output shaft of the motor drives the collar 6 to rotate.

[0045] On the one hand, the collar 6 drives the perimeter transit gauge 7 and the perimeter stop gauge 8 to rotate, and the worker directly observes with the naked eye whether the perimeter transit gauge 7 and the perimeter stop gauge 8 can pass between the high-toothed plate bending part and the detection surface 101.

[0046] On the other hand, the collar 6 will first stretch the elastic pull belt 10, and if the perimeter stop gauge 8 cannot pass, the elastic pull belt 10 will stop stretching after the perimeter stop gauge 8 abuts against the high-toothed plate; if the perimeter stop gauge 8 passes, the elastic pull belt 10 will stop stretching after being stretched to the maximum extent.

[0047] Referring to Figure 2 , the worker manually releases the start-stop button, the motor is de-energized and its output shaft is stopped, the elastic pull belt 10 restores the deformation and drives the collar 6 to reverse, and the perimeter transit gauge 7 and the perimeter stop gauge 8 are reversed to reset, so that the perimeter transit gauge 7 and the perimeter stop gauge 8 are away from the high-toothed plate, thereby facilitating the worker to manually take and place the high-toothed plate.

[0048] Referring to Figure 2 When the motor is damaged and has not been repaired, in order not to affect the smooth progress of detection, the worker will disassemble the mounting block 11, so that the transit-stop gauge 2 in Embodiment 1 is used to continue to detect the high-toothed plate. Therefore, the mounting block 11 and the detection base 1 can adopt two connection forms.

[0049] Referring to Figure 2 and Figure 3 , the first is that the mounting block 11 is bolted with the detection base 1, which is simple to disassemble and assemble; the second is that a vertical assembly groove 102 is opened at the edge of the detection, the top of the assembly groove 102 is open and the bottom is closed, the mounting block 11 extends into the assembly groove 102 and is in sliding fit with the assembly groove 102, and the cross sections of the sliding fit part of the mounting block 11 and the assembly groove 102 are dovetail-shaped, which is also simple to disassemble and assemble.

[0050] The implementation principle of the embodiment 2 is that when the worker places the high pitch tooth plate on the detection base 1, the start-stop button is pressed to realize the power-on of the motor, and the output shaft of the motor drives the sleeve ring 6 to rotate. The sleeve ring 6 drives the rotation of the cycle gauge 7 and the cycle stop gauge 8, and the worker directly observes whether the cycle gauge 7 and the cycle stop gauge 8 can pass between the high pitch tooth plate bending part and the detection surface 101 by naked eyes. At the same time, the sleeve ring 6 will first stretch the elastic pull belt 10, if the cycle stop gauge 8 cannot pass, the elastic pull belt 10 will stop stretching after the cycle stop gauge 8 abuts against the high pitch tooth plate, if the cycle stop gauge 8 passes, the elastic pull belt 10 will stop stretching after being stretched to the maximum. When the worker manually releases the start-stop button, the motor is powered off and its output shaft is stopped, the elastic pull belt 10 restores the deformation, and drives the sleeve ring 6 to reverse, and the cycle gauge 7 and the cycle stop gauge 8 reverse to reset.

[0051] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
