Abstract
Description
Technical Field
[0001] This utility model relates to a workpiece grinding fixture, which can automatically flip the workpiece to achieve grinding on different surfaces of the workpiece. Background Technology
[0002] With the development of automation technology, the processing requirements for the surfaces of many workpieces are becoming increasingly stringent, necessitating grinding to ensure quality. When only one side of a workpiece needs grinding, the device for positioning the workpiece is relatively simple. However, if multiple sides of a workpiece need grinding, manual flipping is often required to achieve grinding on different sides, resulting in extremely low grinding efficiency and poor grinding quality. Summary of the Invention
[0003] The problem to be solved by this utility model is to provide a positioning device for grinding workpieces with multiple surfaces. It first clamps the workpiece with a clamping component, and then automatically flips the workpiece with a flipping component to achieve grinding of multiple surfaces of the workpiece. That is, it realizes grinding of multiple surfaces with one clamping, without the need for manual flipping, which greatly improves grinding efficiency and ensures the grinding effect.
[0004] This utility model discloses a positioning device for grinding workpieces with multiple surfaces. It includes a base, a flipping assembly, and a workpiece clamping assembly. The flipping assembly includes a brake motor, a fixed base, a coupling, a left connecting shaft, a right connecting shaft, and two bearing-equipped fixed seats. The brake motor is fixed on the base, and the two bearing-equipped fixed seats are respectively fixed on the left and right vertical supports of the base. The fixed base is positioned between the two bearing-equipped fixed seats. The two ends of the left connecting shaft are connected to the bearing in the left bearing-equipped fixed seat and the left connecting plate of the fixed base, respectively. The left end of the right connecting shaft is connected to the right connecting plate of the fixed base, the middle section is engaged with the bearing in the right bearing-equipped fixed seat, and the right end is connected to the drive shaft of the brake motor through the coupling. The workpiece clamping assembly is fixed on top of the fixed base.
[0005] Furthermore, the workpiece clamping assembly includes two linear optical axes, four optical axis fixing seats, at least two workpiece clamping units, and a rotary valve connector. Each workpiece clamping unit includes two workpiece clamping blocks, two cylinders, and four linear bearings. The four optical axis fixing seats are respectively fixed at the four corners of the base plate. The two ends of each linear optical axis are respectively connected to the bearings in the left and right optical axis fixing seats. Each workpiece clamping block is provided with two linear bearings, one in front and one in back, which are respectively fitted onto the front and rear linear optical axes. The cylinders are fixed on the base plate of the base, and their telescopic rods are connected to the workpiece clamping blocks. A rotary valve connector is provided at the outer end of the left bearing fixing seat.
[0006] Furthermore, the positioning device for grinding also includes a photoelectric detection component, which includes a photoelectric switch, a light-transmitting plate, and a photoelectric detection plate. The photoelectric switch is fixedly connected to the base, and the photoelectric detection plate is fixedly connected to the bearing-mounted seat on the right. The light-transmitting plate is sleeved on the output shaft of the brake motor and located between the photoelectric switch and the photoelectric detection plate. The light-transmitting plate is provided with multiple light-transmitting holes.
[0007] Furthermore, the number of light-transmitting holes on the polished plate is the same as the number of polished surfaces of the workpiece, and the angle between each light-transmitting hole is related to the position between the multiple polished surfaces of the workpiece.
[0008] The advantages of this positioning device for grinding are: it first clamps the workpiece with a clamping component, and then automatically flips the workpiece with a flipping component to grind multiple sides of the workpiece. This achieves multi-sided grinding with one clamping, eliminating the need for manual flipping, greatly improving grinding efficiency and ensuring the grinding effect. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] Example 1
[0020] from Figure 1 , Figure 2 , Figure 3 As can be seen, this utility model discloses a positioning device for grinding workpieces with multiple surfaces. It includes a base 16, a flipping assembly, and a workpiece clamping assembly. The flipping assembly includes a brake motor 1, a fixed base 11, a coupling 15, a left connecting shaft 13, a right connecting shaft 9, and two bearing-mounted fixed seats 5. The brake motor 1 is fixed on the base 16, and the two bearing-mounted fixed seats 5 are respectively fixed on the left and right vertical supports of the base 16. The fixed base 11 is located between the two bearing-mounted fixed seats 5. The two ends of the left connecting shaft 13 are respectively connected to the bearing in the left bearing-mounted fixed seat 5 and the left connecting plate of the fixed base 11. The left end of the right connecting shaft 9 is connected to the right connecting plate of the fixed base 11, the middle section is engaged with the bearing in the right bearing-mounted fixed seat 5, and the right end is connected to the drive shaft of the brake motor 1 through the coupling 15. The workpiece clamping assembly is fixed on the fixed base 11.
[0021] The connecting plates at both ends of the fixed base 11 rotate around the two bearing-bearing fixed seats 5 via the left connecting shaft 13 and the right connecting shaft 9. When the brake motor 1 is working, its transmission shaft drives the right connecting shaft 9 to rotate via the coupling 15, thereby rotating the fixed base 11, causing the workpiece clamping assembly to rotate, and positioning each grinding surface of the workpiece 17 in the grinding position. The grinding device 18 then performs grinding on the workpiece 17. The base 16 here can be part of an automatic grinding machine.
[0022] Example 2
[0023] from Figure 1 , Figure 2 , Figure 3 As can be seen, the positioning device for grinding of this utility model includes a workpiece clamping assembly comprising two linear optical axes 6, four optical axis fixing seats 14, at least two workpiece clamping units, and a rotary valve connector 12. Each workpiece clamping unit includes two workpiece clamping blocks 10, two cylinders 7, and four linear bearings 8. The four optical axis fixing seats 14 are respectively fixed at the four corners of the base plate of the fixed base 11. The two ends of each linear optical axis 6 are respectively connected to the bearings in the left and right optical axis fixing seats 14. Each workpiece clamping block 10 is provided with two front and rear linear bearings 8 below it. The front and rear linear bearings 8 are respectively sleeved on the front and rear linear optical axes 6. The cylinders 7 are fixed on the base plate of the fixed base 11, and their telescopic rods are connected to the workpiece clamping blocks 10. The outer end of the left bearing fixing seat 5 is provided with a rotary valve connector 12.
[0024] When cylinder 7 operates, it pulls or pushes the workpiece clamping block 10, causing it to move left and right along the linear optical axis 6 via the lower linear bearing 8. Two workpiece clamping blocks 10 in the same workpiece clamping unit move towards or away from each other to clamp or release the workpiece 17. When the workpiece 17 is clamped, it rotates with the fixed base 11 and is ground by the grinding device 18. When the workpiece 17 is released, the ground workpiece 17 is removed. Note that when the brake motor 1 drives the fixed base 11 to rotate, the rotary valve connector 12 does not drive the air pipe to rotate.
[0025] Example 3
[0026] from Figure 1 , Figure 2 , Figure 3 It can be seen that the positioning device for grinding of this utility model also includes a photoelectric detection component, which includes a photoelectric switch 2, a light-transmitting plate 3, and a photoelectric detection plate 4. The photoelectric switch 2 is fixedly connected to the base 16, and the photoelectric detection plate 4 is fixedly connected to the bearing-supported fixing seat 5 on the right side. The light-transmitting plate 3 is sleeved on the output shaft of the brake motor 1 and is located between the photoelectric switch 2 and the photoelectric detection plate 4. The light-transmitting plate 3 is provided with multiple light-transmitting holes.
[0027] After one side of workpiece 17 is polished, step on the foot switch to rotate the brake motor 1. The light-transmitting plate 3 rotates with the brake motor 1, while the photoelectric switch 2 and photoelectric detection plate 4 remain stationary. When the light from the photoelectric switch 2 cannot pass through the hole in the light-transmitting plate 3 and is detected by the photoelectric detection plate 4, the output of the photoelectric switch 2 closes, and the brake motor 1 continues to rotate. When the light from the photoelectric switch 2 passes through the hole in the light-transmitting plate 3 again and is detected by the photoelectric detection plate 4, the output of the photoelectric switch 2 disconnects, and the brake motor 1 stops rotating. At this time, the stop surface of workpiece 17 facing the polishing device 18 is the next surface to be polished. This process is repeated until all surfaces of workpiece 17 are polished and then removed.
[0028] Example 4
[0029] from Figure 4 It can be seen that in the positioning device for grinding of this utility model, the number of light-transmitting holes on the light-transmitting plate 3 is the same as the number of grinding surfaces of the workpiece 17, and the angle between each light-transmitting hole is related to the position between the multiple grinding surfaces of the workpiece 17.
[0030] The number and angle of the light-transmitting holes on the light-transmitting plate 3 must be set to ensure that all the necessary grinding surfaces on the workpiece 17 are ground accurately: In this application, the workpiece 17 has four grinding surfaces, so the light-transmitting plate 3 has four light-transmitting holes.
[0031] The working principle of the positioning device for grinding of this utility model is as follows: First, two workpieces 17 (the number of workpieces is the same as the number of clamping units) are placed on the workpiece clamping block 10. Then, the workpiece clamping block 10 moves along the linear optical axis 6 under the action of the bottom cylinder 7 to clamp the workpieces 17. Then, the grinding device 18 is started, so that the grinding wheel moves left, right and back and forth to grind the workpieces 17. After one side of the workpiece 17 is ground, the foot switch 15 is pressed, and the brake motor 1 is activated by the self-locking of the energized relay. The foot switch 15 is released, and the light-transmitting plate 3 rotates with the motor spindle. Since the photoelectric switch 2 is fixed, the light of the photoelectric switch 2 cannot pass through the hole of the light-transmitting plate and be detected by the photoelectric detection plate 4. The output of the photoelectric switch 2 is closed, and the motor will continue to rotate. When the light of the photoelectric switch 2 passes through the hole of the light-transmitting plate 3 again and is detected by the detection plate 4, the photoelectric switch is disconnected and the output is disconnected. The motor stops rotating. At this time, the stopping surface of the workpiece 17 is exactly the next surface to be ground. After repeating this process several times, after all surfaces of the workpiece 17 are ground, the ground workpiece 17 is removed and replaced with other workpieces. The workpiece 17 in this invention has four grinding surfaces, thus providing four grinding positions, such as... Figure 5 , 6 As shown in 7, 8, and 9.
[0032] The advantages of this positioning device for grinding are: it first clamps the workpiece with a clamping component, and then automatically flips the workpiece with a flipping component to grind multiple sides of the workpiece. This achieves multi-sided grinding with one clamping, eliminating the need for manual flipping, greatly improving grinding efficiency and ensuring the grinding effect.
