Description

Technical Field

[0001] The utility model relates to the technical field of cam divider detection equipment, in particular to the general assembly of a cam divider precision detection bench. Background Technique

[0002] The cam divider is also called cam indexing device and intermittent divider in engineering. It is a high-precision rotary device. The cam divider inputs power through the input end and outputs through the output end after a certain transmission ratio. In production and processing, after the output end outputs intermittently, the parts can be moved to the next process. The accuracy of the output angle of the output end is particularly important. When the angle accuracy of the output end is insufficient, the yield of processing decreases. Therefore, it is necessary to detect the accuracy of the cam sensor to ensure the accuracy of the cam sensor during the production process and thus ensure the yield. In the prior art, the accuracy of the product is mostly observed by visual inspection, resulting in inaccurate accuracy detection. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an on-line automatic detection device applicable to the anti-misassembly of engine parts, which can detect multiple parts at one time and effectively reduce the occupied space.

[0004] To solve the above technical problem, the utility model includes a frame, and its structural feature is that: a workbench is arranged on the frame, a cam divider is installed on the workbench, the cam divider includes an output end and an input end, a driving device for driving the rotation of the input end of the cam divider is installed on the frame, a positioning device for fixing the cam divider is arranged on the workbench, a detection device capable of adjusting the height and position is installed on the workbench, and the detection device can detect the rotation angle of the output end of the cam divider.

[0005] After adopting the above structure, the cam divider is installed on the workbench, and then the position of the cam divider is fixed by the positioning device to ensure the stability of the cam divider during operation. After the cam divider is fixed, the height and position of the detection device are adjusted according to the model of different cam dividers, so that the detection device is aligned with the output end of the cam divider. The input end of the cam divider is driven to rotate by the driving device to drive the cam divider to operate. Compared with manual driving, it saves human resources. The rotation angle of the output end of the cam divider is detected by the detection device, and then the accuracy of the angle rotated by the cam divider each time is detected. The detection device can adjust the position according to the cam divider and is applicable to various models of cam dividers, thus increasing the applicability of the device.

[0006] The positioning device includes a plurality of intermediate pads arranged horizontally. A positioning gap is provided between adjacent intermediate pads. The cross-section of the positioning gap is an inverted T shape. A T-shaped nut capable of entering the positioning gap is provided at the lower end of the cam divider. Baffles for restricting the left and right positions of the cam divider are provided on the left and right sides of the cam divider. The intermediate pads are arranged horizontally, and the positioning gaps between adjacent intermediate pads are arranged horizontally. The T-shaped nut enters the inverted T-shaped positioning gap, and the up-and-down and front-and-back movements of the cam divider are restricted by the positioning gap. Baffles are installed at the left and right positions of the cam divider, and the left and right positions of the cam divider are restricted by the contact of the baffles, thereby ensuring the stability of the cam divider during operation.

[0007] The detection device includes a detection head and an adjustment device capable of adjusting the left, right, up, and down positions of the detection head. The detection head includes an encoder mounting plate installed on the adjustment device. An encoder is installed on the encoder mounting plate. A through hole is provided on the encoder mounting plate. A connecting shaft is sleeved in the through hole. A clamping flange for clamping the output end of the cam divider is provided at the lower end of the connecting shaft. The connecting shaft and the clamping flange are connected by a coupling. The upper end of the connecting shaft extends into the encoder through the through hole of the encoder mounting plate. The encoder is connected to a signal conversion device. The output end of the cam divider is clamped by the clamping flange. When the output end of the cam divider rotates, the clamping flange is driven to rotate together. The coupling on the clamping flange drives the upper connecting shaft to rotate coaxially and at the same speed. The rotation angle and speed of the connecting shaft are detected by the encoder, and then the rotation accuracy of the output shaft of the cam divider is detected to ensure the stability of the detection. The encoder signal is converted into a readable signal by the signal conversion device. When the models of the cam dividers are different, the output ends of the cam dividers are different. After adopting this structure, the stability of the detection can be ensured under different models, and the applicability of the device is improved.

[0008] A display screen is installed on the frame. The display screen is connected to the signal conversion device of the encoder. The detected data is directly displayed on the display screen, which is convenient for subsequent adjustment and screening, and improves work efficiency.

A longitudinal axis arranged in the front-back direction is installed on the column. The column and the longitudinal axis are installed and fastened through a longitudinal axis connecting block. The longitudinal axis connecting block can clamp / loosen the column and the longitudinal axis respectively. The detection head is installed at the front end of the transverse axis. After the longitudinal axis connecting block loosens the column, the relative position and angle between the longitudinal axis connecting block and the column can be adjusted, and then the height and angle of the longitudinal axis can be adjusted. When the longitudinal axis connecting block loosens the longitudinal axis, the front-back position between the longitudinal axis and the longitudinal axis connecting block can be adjusted, and then the front-back position and height of the detection head can be adjusted to make the detection head adapt to different models of cam dividers, ensuring applicability.

[0010] A horizontal axis is provided at the front end of the vertical axis. The vertical axis and the horizontal axis are tightly installed through a horizontal axis connecting block. The horizontal axis connecting block can clamp / loosen the horizontal axis and the vertical axis respectively. An encoder connecting block is installed on the horizontal axis, and the detection head is installed on the encoder connecting block. Through the setting of the horizontal axis, the vertical axis is avoided, and then the adjustment in the front-back direction can be carried out, increasing the adjustment accuracy of the adjustment device while ensuring the installation space of the detection head, adjusting the center of gravity of the detection device, and ensuring stability.

[0011] The driving device is a servo motor, which can accurately ensure the input efficiency and input stability, saving human resources.

[0012] A feeding device is installed on the frame. The feeding device can push the cam divider to be installed in the intermediate backing plate, reducing the labor cost and improving the efficiency.

[0021] As Figures 1-5As shown in the figure, the utility model includes a frame 1, a workbench 2 is arranged on the frame 1, a cam divider 3 is installed on the workbench 2, and a detection device is installed at the front end of the cam divider 3. A positioning device for fixing the cam divider 3 is arranged on the workbench 2, feeding and discharging devices 92 are arranged on the left and right sides of the cam divider 3, and a driving device 4 for driving the cam divider 3 to rotate is arranged at the rear end of the cam divider 3. For the convenience of description, assume Figure 1 the left side is the left, and the right side is the right, Figure 1 inward between the vertical directions is the front, and outward perpendicular to the paper surface is the rear. The feeding and discharging device 92 is used to complete the feeding of the cam divider 3. After the feeding is completed, the cam divider 3 is fixed on the workbench 2, the position of the detection device is adjusted, and the detection device is installed on the output end of the cam divider 3. Subsequently, the driving device 4 is used to drive the cam divider 3 to operate. After the operation, the operation angle of the cam divider 3 is detected by the detection device. The output ratio of the input end and the output end of the cam divider 3 is used to determine the angle that the cam divider 3 should output. By comparing the should-output angle with the operation angle, the accuracy of the cam divider 3 is determined.

[0022] As Figures 1-3 shown, the positioning device includes a plurality of intermediate pads 51 arranged horizontally left and right on the workbench 2. An inverted T-shaped groove is arranged between adjacent intermediate pads 51, and the inverted T-shaped groove is arranged in the left and right directions. The width of the upper part of the inverted T-shaped groove in the front and rear directions is smaller than the width of the lower part in the front and rear directions. A T-shaped nut is installed at the bottom of the cam divider 3. By inserting the T-shaped nut into the inverted T-shaped groove, the position of the T-shaped nut in the front and rear directions is restricted by the inverted T-shaped groove, and thus the position of the cam divider 3 in the front and rear directions is restricted. A limiting device for restricting the left and right movement of the cam sensor is installed on the intermediate pad 51. In this embodiment, the limiting device is a baffle 54, and the baffle 54 includes a left baffle 54 and a right baffle 54. The left baffle 54 is located on the left side of the cam divider 3, and the left baffle 54 is in contact with the left section of the cam divider 3. The right baffle 54 is located on the right side of the cam divider 3, and the right baffle 54 is in contact with the right end face of the cam divider 3. Through holes are arranged on the left baffle 54 and the right baffle 54. T-shaped nuts are arranged on the lower sides of the left baffle 54 and the right baffle 54. The T-shaped nuts are inserted into the inverted T-shaped groove, and bolts corresponding to the T-shaped nuts are installed in the through holes of the left baffle 54 and the right baffle 54. The positions of the left baffle 54 and the right baffle 54 are fixed by the bolts, and thus the position of the cam divider 3 is fixed.

[0023] As Figures 1-7As shown in the figure, the detection device includes a detection head 6 and an adjustment device 8 capable of adjusting the left-right, up-down positions of the detection head 6. The adjustment device 8 includes a column base fixed on the workbench 2, and the column base is fixed on the workbench 2 by bolts. A vertically arranged column 81 is installed inside the base, and a longitudinally moving connection block 83 capable of moving up and down is provided on the column 81. The longitudinally moving connection block 83 is sleeved on the column 81, and a longitudinally arranged longitudinal axis 82 is sleeved on the longitudinally moving connection block 83. One end of the longitudinal axis 82 is installed with a transverse connection block 85, and through the transverse connection block 85, a horizontally arranged transverse axis 84 is installed at the rear end of the longitudinal axis 82, and an encoder connection block 86 is installed on the transverse axis 84. The detection head 6 includes an encoder 64 base installed on the encoder connection block 86. There is a through hole in the encoder 64 base. An encoder 64 is installed at the upper end of the encoder 64 base, and a connecting shaft is installed in the encoder 64. The connecting shaft extends downward through the through hole at the lower end of the encoder 64 base. A clamping flange 65 capable of clamping the output end of the cam divider 3 is provided at the lower end. A connecting rod is provided on the clamping flange 65, and the connecting rod of the clamping flange 65 is connected to the connecting shaft through a coupling 66. When the input end of the cam divider 3 is driven by the driving device 4, the output end rotates. The clamping flange 65 rotates with the rotation of the output end, and then drives the connecting shaft to rotate through the coupling 66. The encoder 64 detects the rotation angle of the connecting shaft, and then transmits the encoded signal to the sensor, and then determines the output accuracy of the output end of the cam sensor.

[0024] As Figures 5-7 shown in the figure, in the adjustment device 8, a vertically arranged through hole is provided on the longitudinally moving connection block 83, and the cross-sectional shape of the through hole is the same as the cross-sectional shape of the column 81. That is, the longitudinally moving connection block 83 is sleeved on the column 81 through the vertically arranged through hole. The longitudinally moving connection block 83 is provided with a gap from the through side to the through hole, and a screw capable of tightening to reduce the gap is installed on the longitudinally moving connection block 83. When the gap is reduced, the vertically arranged through hole is deformed to a certain extent, the clamping force of the through hole on the column 81 increases, and the friction force increases, thereby clamping and fixing the position of the longitudinally moving connection block 83. When the screw is screwed outwards, the gap is restored. At this time, the position of the longitudinally moving connection block 83 can be adjusted, and then the height of the longitudinal axis 82 can be adjusted. Then, the height or angle of the clamping flange 65 and the encoder 64 can be adjusted according to the model of the cam divider 3, so as to adapt to the output end of the cam divider 3 and improve the applicability of the detection device. At the same time, the longitudinally moving connection block 83 is sleeved on the column 81 and can rotate along the axis of the column 81. Then, the angle of the clamping flange 65 and the encoder 64 can be adjusted by rotation, and then the position of the detection device can be adjusted according to the position of the cam divider 3 installed on the workbench 2. By using this method, the front-back direction of the detection head 6 can be adjusted.

[0025] As Figures 5-7As shown in the figure, a through hole in the front-back direction is provided on the vertical axis connecting block 83. The cross-section of the through hole in the front-back direction is the same as the cross-section of the vertical axis 82. At the same time, a gap communicating with the through hole in the front-back direction is also provided. By adjusting the gap, the clamping / relaxing of the vertical axis 82 can be realized, and then the front-back position of the vertical axis 82 can be adjusted. Furthermore, the front-back position of the clamping flange 65 can be adjusted. When different models of cam splitters 3 are installed on the workbench 2, by adjusting the front-back position of the vertical axis 82, the position of the clamping flange 65 can be adjusted, which is convenient for the clamping flange 65 to clamp the output ends of cam splitters 3 at different positions. The applicability of the device is improved. Furthermore, the adjustment in the front-back direction can be carried out, which increases the adjustment accuracy of the adjustment device 8 while ensuring the installation space of the detection head 6, adjusts the center of gravity of the detection device, and ensures stability.

[0026] As Figures 5-7 shown, in this embodiment, a horizontal axis 84 arranged in the left-right direction is provided at the front end of the vertical axis 82. The vertical axis 82 and the horizontal axis 84 are fixedly installed through a horizontal axis connecting block 85. The horizontal axis connecting block 85 is also provided with a through hole, and a gap is provided on one side of the through hole. By adjusting the gap, the horizontal axis 84 and the vertical axis 82 can be clamped / loosened respectively. An encoder connecting block 86 is installed on the horizontal axis 84, and the detection head 6 is installed on the encoder connecting block 86. Through the setting of the horizontal axis 84, the position of the detection head 6 avoids the vertical axis 82. Furthermore, the adjustment in the front-back direction can be carried out, which increases the adjustment accuracy of the adjustment device 8 while ensuring the installation space of the detection head 6, adjusts the center of gravity of the detection device, and ensures stability.

[0027] As Figure 1 、 2 As shown in FIGS. 3 and 4, a display is installed beside the frame 1. The data detected by the encoder 64 is converted into a signal through a signal conversion device sensor and displayed on the display, and the detection result is digitally displayed for easy reading.

[0028] As Figure 1 、 2 As shown in FIGS. 3 and 4, a middle plate is provided on the frame 1, a placing plate is placed on the middle plate, and parts required for a plurality of different models of clamping flanges 65 and detection devices are placed on the placing plate. It is convenient to replace relevant parts when detecting different models of cam splitters 3. The installation efficiency is improved.

[0029] As Figure 1As shown, the input end of the cam divider 3 is provided with a driving device 4. In this embodiment, the driving device drives the machine frame. A driving base capable of moving back and forth is installed on the machine frame, and a servo motor is installed on the driving base. The driving base and the machine frame are driven by a threaded screw. The screw is arranged front and back. When the screw rotates, the driving base moves back and forth. The operation of the cam divider is started by driving the servo motor. The servo motor can control the rotation speed and the number of rotation turns of the input end, accurately compare the output ratio of the input end and the output end, and then accurately monitor. At the same time, the servo motor can move back and forth to adapt to the position of the cam sensor, improving adaptability. Compared with manual rotation by the operator, the detection accuracy and efficiency are improved.

[0030] As Figure 1 , 4 As shown, in this embodiment, a feeding device 91 is provided on the right side of the machine frame 1. The feeding device 91 includes a feeding frame capable of moving up and down. A feeding cylinder is installed on the feeding frame. A feeding rod capable of telescoping is arranged in the feeding cylinder. A feeding plate is installed at the front end of the feeding rod. The front and back movement of the feeding rod drives the front and back movement of the discharging plate. When the discharging plate abuts against the cam divider, the feeding rod is telescoped to push the cam divider to the corresponding position, and then fixed in position for detecting the cam divider. After the detection of the cam divider is completed, the positioning device is removed, and the feeding cylinder continues to push to the left to push the cam divider to the left side of the workbench for discharging. The feeding cylinder is installed on the feeding frame, and the height of the feeding frame can be adjusted. When a group of cam dividers are detected, the cylinder arranged on the feeding frame drives the feeding frame to move down. Guide columns are provided on the machine frame, and the feeding frame moves up and down along the guide columns to avoid the next cam divider and prevent interference between the feeding cylinder and the cam divider. Using the feeding device 91 for feeding and discharging reduces the labor cost and improves the efficiency.
