Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically a multi-station grinding workstation. Background Technology

[0002] In industries such as metal parts processing, automobile manufacturing, and machinery manufacturing, polishing is an indispensable process. It can not only improve the surface quality of products, but also enhance their aesthetics and durability.

[0003] Current grinding equipment has a single station for fixing workpieces. Therefore, when fixing workpieces on the fixture, one workpiece must be ground and then removed from the fixture before another workpiece can be fixed. It is not possible to fix another workpiece in advance while one workpiece is being ground, which makes the whole operation process too cumbersome and greatly reduces the grinding efficiency of the grinding equipment.

[0004] Chinese patent discloses a multi-station casting steel grinding device (authorization announcement number CN217143474U). This patented technology, through the cooperation of a rotating disc, a clamping part, a foot pedal, and a plug-in part, allows the grinding of one casting steel part to be completed in advance by removing the grinding of the right side of the casting steel part in advance, and then fixing the other casting steel part to be ground onto the clamping part on the right side. This cycle can be repeated to complete the grinding of casting steel parts more efficiently. In addition, the device can fix the other casting steel part in advance while grinding one casting steel part, making the whole operation process simpler and greatly improving the grinding efficiency of the device.

[0005] However, it has certain drawbacks: vibrations are constantly generated during the grinding process, and these vibrations are transmitted to the clamping screw, causing it to rotate unnecessarily. This results in the two clamping plates shifting away from the workpiece, which in turn affects the fixation of the workpiece. This not only affects the precision and quality of the grinding, but may also cause the workpiece to fall off during the grinding process, causing damage or safety hazards. Utility Model Content

[0006] The purpose of this invention is to provide a multi-station grinding workstation to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-station grinding workstation includes a grinding table, a grinding mechanism is provided on the upper surface of the grinding table, and a support base is fixedly connected to the upper surface of the grinding table in front of the grinding mechanism. A second motor is fixedly connected to the lower surface of the support base, and a turntable is fixedly connected to the output end of the second motor. Multiple clamping seats are fixedly connected to the outer edge of the upper surface of the turntable. An adjusting rod is movably connected through the side surface of the clamping seat away from the center of the turntable. Two adjusting plates are threaded to the external surface of the adjusting rod, and a clamping plate is fixedly connected to the upper end of the adjusting plate.

[0009] A ratchet is fixed to the outer surface of the adjusting rod and outside the clamping seat. A positioning mechanism is provided on the side surface of the clamping seat away from the center of the turntable and above the adjusting rod.

[0010] As a further embodiment of this utility model: the grinding mechanism includes a support frame, a telescopic cylinder is fixedly connected to the upper surface of the support frame, a support plate is fixedly connected to the telescopic end of the telescopic cylinder, a first motor is fixedly connected to the upper surface of the support plate, and a grinding disc is fixedly connected to the output end of the first motor.

[0011] As a further embodiment of this utility model: the positioning mechanism includes a pawl, a rotating rod is rotatably connected to the end of the pawl away from the ratchet, and a spring is fixedly connected to the surface of the pawl away from the ratchet, and a positioning block is fixedly connected to one end of the spring.

[0012] As a further embodiment of this utility model: one end of the adjusting rod is rotatably connected to the inner side surface of the clamping seat, the adjusting plate moves through the upper surface of the clamping seat, and the clamping plate is slidably connected to the upper surface of the clamping seat.

[0013] As a further embodiment of this utility model: the lower end of the support frame is fixed to the upper surface of the grinding table, and the grinding disc is directly opposite the rear clamping seat.

[0014] As a further embodiment of this utility model: the pawl is attached to the ratchet, and the rotating rod and the positioning block are both fixed to the side surface of the clamping seat away from the center of the turntable.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model has multiple clamping seats evenly arranged on the turntable, which can fix multiple workpieces at the same time. This allows the operator to remove the already-polished workpiece from another clamping seat while the grinding mechanism is grinding the workpiece on one clamping seat, thereby realizing continuous grinding processing and improving work efficiency.

[0017] 2. This utility model has a positioning mechanism in which the pawl engages with the ratchet, preventing the adjusting rod from rotating counterclockwise when it is not needed. This avoids the adjusting rod from rotating due to vibration during grinding, and thus prevents the clamping plate from loosening its grip on the workpiece. Attached Figure Description

Detailed Implementation

[0023] Please see Figures 1 to 3 In this embodiment of the present invention, a multi-station grinding workstation includes a grinding table 1. A grinding mechanism 2 is provided on the upper surface of the grinding table 1. The grinding mechanism 2 includes a support frame 3. The lower end of the support frame 3 is fixedly connected to the upper surface of the grinding table 1. A telescopic cylinder 4 is fixedly connected to the upper surface of the support frame 3. A support plate 5 is fixedly connected to the telescopic end of the telescopic cylinder 4. A first motor 6 is fixedly connected to the upper surface of the support plate 5. A grinding disc 7 is fixedly connected to the output end of the first motor 6. A support seat 8 is fixedly connected to the upper surface of the grinding table 1 in front of the grinding mechanism 2. A second motor 9 is fixedly connected to the lower surface of the support seat 8. The output end of the second motor 9 is fixedly connected to a turntable 10. Multiple clamping seats 11 are fixedly connected to the outer edge of the upper surface of the turntable 10. The grinding disc 7 is directly opposite the rear clamping seat 11. An adjusting rod 12 is movably connected through the side surface of the clamping seat 11 away from the center of the turntable 10. One end of the adjusting rod 12 is rotatably connected to the inner side surface of the clamping seat 11. Two adjusting plates 13 are threadedly connected to the outside of the adjusting rod 12. The adjusting plates 13 movably pass through the upper surface of the clamping seat 11. A clamping plate 14 is fixedly connected to the upper end of the adjusting plate 13. The clamping plate 14 is slidably connected to the upper surface of the clamping seat 11.

[0024] The telescopic cylinder 4 is preferably an electric cylinder or a pneumatic cylinder;

[0025] The first motor 6 is used to drive the grinding disc 7 to rotate, thereby performing the grinding work;

[0026] The threads of the two adjusting plates 13 are opposite. That is, when the adjusting rod 12 is rotated clockwise, the two adjusting plates 13 move towards the middle at the same time. When the adjusting rod 12 is rotated counterclockwise, the two adjusting plates 13 move to the sides respectively.

[0027] Two clamping plates 14 are used to hold the workpiece for easy grinding;

[0028] The second motor 9 is preferably a servo motor or a stepper motor. It rotates at a fixed angle each time it starts, so that different clamping seats 11 are directly opposite the grinding disc 7. Therefore, when the grinding disc 7 grinds the workpiece on a clamping seat 11, the operator can disassemble the already ground workpiece on the clamping seat 11 and install a new workpiece, which improves processing efficiency.

[0029] exist Figure 1 , Figure 3 and Figure 4 In the middle: a ratchet 15 is fixedly connected to the outer surface of the adjusting rod 12 and to the outside of the clamping seat 11. A positioning mechanism 16 is provided on the side surface of the clamping seat 11 away from the center of the turntable 10 and above the adjusting rod 12. The positioning mechanism 16 includes a pawl 17, which is attached to the ratchet 15. A rotating rod 18 is rotatably connected to the end of the pawl 17 away from the ratchet 15. A spring 19 is fixedly connected to the side surface of the pawl 17 away from the ratchet 15. A positioning block 20 is fixedly connected to one end of the spring 19. The rotating rod 18 and the positioning block 20 are both fixedly connected to the side surface of the clamping seat 11 away from the center of the turntable 10.

[0030] Pawl 17 engages with ratchet 15, allowing ratchet 15 to rotate clockwise but not counterclockwise, thus preventing adjustment rod 12 from rotating counterclockwise and consequently preventing the two adjustment plates 13 from moving to the sides, ensuring clamping stability.

[0031] After pulling the pawl 17 away from the ratchet 15, the adjusting lever 12 can be rotated counterclockwise.

[0032] The working principle of this utility model is as follows: When in use, the operator places the workpiece on the clamping seat 11 and between the two clamping plates 14, and rotates the adjusting rod 12 clockwise so that the two clamping plates 14 move towards the middle at the same time until the workpiece is clamped. The workpieces are fixed on all the clamping seats 11 in the above manner. Then, the first motor 6 drives the grinding disc 7 to rotate, and the telescopic cylinder 4 drives the grinding disc 7 to descend to grind the workpiece. After grinding, the telescopic cylinder 4 returns to its original position, and the second motor 9 drives the turntable 10 to rotate at a certain angle so that another workpiece is facing the grinding disc 7. The second motor 9 stops, and the telescopic cylinder 4 extends to drive the grinding disc 7 to grind. During this process, the operator pulls the pawl 17 away from the ratchet 15, and then rotates the adjusting rod 12 counterclockwise to separate the two clamping plates 14, removes the ground workpiece, and installs a new workpiece. This cycle is repeated continuously for grinding.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
