One end of the traction rope is connected to the connecting rod, and the other end passes around the guide wheel and is connected to the weight.

[0008] When the grinding disc is subjected to downward pressure by the clamp, and the pressure is greater than the weight of the weight, the weight exerts an upward force on the connecting rod through the traction rope, causing the grinding disc to abut against the clamp holding the workpiece.

The core has a through hole, and the through hole contains a plurality of core petals that can slide relative to the through hole and can open and close. The plurality of core petals form a clamping space for clamping a workpiece. The end of the through hole away from the core petals has a limiting member that can slide relative to the through hole. The limiting member is fixedly connected to the core petals by a connecting block. The end of the through hole near the core petals has a step. The bottom of the limiting member, the step, and the sidewalls of each core petal form an elastic member that can press against the limiting member and open the plurality of core petals to unlock the workpiece. The two ends of the elastic member are fixedly connected to the limiting member and the step, respectively. The lower end of each core petal corresponds to the grinding disc.

[0014] Preferably, it further includes a clamp base and a rotating body arranged vertically on the clamp base. The rotating body is ball-jointed to the clamp.

The second fixed seat is provided with a plurality of third through holes for the rotating body to be placed. The first fixed seat is divided into a first space for the second fixed seat to be placed and a second space for the fixture to be placed by a partition plate. The partition plate is provided with a fourth through hole for connecting the first space and the second space. The bottom of the rotating body passes through the fourth through hole and is connected to the fixture.

[0017] Preferably, it also includes a cooling water nozzle corresponding to the grinding disc, and the cooling water nozzle is connected to a water source.

[0018] By adopting the aforementioned design scheme, the beneficial effects of this utility model are as follows: the drive mechanism moves the workpiece on the fixture, and the grinding disc grinds the workpiece. When the grinding disc is subjected to downward pressure from the fixture, and this pressure is greater than the weight of the weight, the weight exerts an upward force on the connecting rod through the traction rope, causing the grinding disc to press against the fixture holding the workpiece. The entire process requires no manual resetting of the grinding disc; this utility model can automatically reset it, saving manpower and improving work efficiency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 5

[0027] A novel grinding machine includes a frame 10, a worktable 20 mounted on the frame 10, a slide plate 21 mounted on the worktable 20, several clamps 30 mounted on the frame 10 for holding workpieces 90 to be processed, grinding discs 40 corresponding to the clamps 30, a drive device for driving the clamps 30 to move, and a grinding disc resetting drive mechanism corresponding to the grinding discs 40. The drive device includes a first drive mechanism 51 for driving the slide plate 21 to slide on the worktable 20, a second drive mechanism 52 for driving the clamps 30 to move longitudinally, and a third drive mechanism 53 for driving the grinding discs 40 to rotate. In this embodiment, both the worktable 20 and the slide plate 21 are arranged horizontally. The grinding machine of this invention can be used to process columnar optical crystals, processing a hemispherical surface at one end of the columnar optical crystal. In this embodiment, the clamps 30 are detachably mounted on the slide plate 21, and the grinding discs 40 are rotatably mounted on the worktable 20. The grinding discs 40 are provided with hemispherical grinding grooves 401. During processing, the workpiece 90 contacts the grinding grooves 401 for grinding. The present invention provides multiple clamps 30, each clamp 30 corresponding to a grinding disc 40. It is worth noting that in this embodiment, at least one slide plate 21 can be mounted on the worktable 20, and the first drive mechanism 51 drives each slide plate 21 to move horizontally. Specifically, as shown... Figure 1 A first drive mechanism 51 drives four slide plates 21 to move back and forth on the worktable 20. That is, the four slide plates 21 are connected to the instrument in pairs. Of course, multiple first drive mechanisms 51 can also be set, as long as they can enable each slide plate 21 to move back and forth in the horizontal direction. Other methods are not detailed here. In addition, in this embodiment, at least one clamp 30 and at least one grinding disc 40 can be set on the slide plate 21 (one clamp 30 and one grinding disc 40 are defined as a group of workstations). The number of clamps 30 and grinding discs 40 is the same, and they are set one-to-one. A second drive mechanism 52 drives each clamp 30 to move in the vertical direction. Specifically, as shown... Figure 1 and Figure 2 A second drive mechanism 52 drives five clamps 30 to move back and forth on the slide plate 21. By mounting the five clamps 30 together on the clamp base 36 (which will be described in detail below), the second drive mechanism 52 drives the clamp base 36 to move the five clamps 30 back and forth in the vertical direction.

[0028] For easier understanding, this embodiment only provides a skateboard 21 and five workstations to describe the present invention in detail. For details, please refer to [link / reference needed]. Figure 3 and Figure 4 Other feasible methods are not detailed here.

[0029] Furthermore, the worktable 20 is provided with a first slide rail 22. In this embodiment, the first slide rail 22 is a single rail, but it can also be provided with double rails or multiple rails, depending on the actual situation. The first slide rail 22 is horizontally arranged on the worktable 20.

[0030] Furthermore, the first drive mechanism 51 includes a first motor 511 fixedly mounted on the worktable 20, a rotating block 512 connected to the output shaft of the first motor 511, and a drive link 513 hinged to the rotating block 512 and eccentrically positioned relative to the rotating block 512. The other end of the drive link 513 is connected to the slide plate 21, and the drive link 513 is positioned horizontally. The clamp base 36 is mounted on the slide plate 21 to drive the slide plate 21, clamp base 36, and each clamp 30 to reciprocate along the length of the first slide rail 22 via the first motor 511. In this embodiment, the first drive mechanism 51 is not limited to the structure of the rotating block 512 and the drive link 513; other drive mechanisms capable of driving the slide plate 21 to move back and forth within a predetermined range can also be used, which will not be described in detail here.

[0031] Furthermore, the second drive mechanism 52 includes a second base 521 mounted on the slide plate 21, a cylinder 522 fixedly mounted on the second base 521, and a telescopic rod 523 telescopically mounted inside the cylinder 522. The end of the telescopic rod 523 is connected to a clamp base 36 so that the clamp base 36 and the clamp 30 can be moved up and down on the second base 521 by the telescopic rod 523 of the cylinder 522.

[0032] A first base 41 and a grinding disc base 42, which are mounted on the first base 41 and can slide up and down along the first base 41, are fixedly mounted on the worktable 20. Specifically, several parallel second slide rails 411 are erected on the side wall of the first base 41. The number of second slide rails 411 is the same as the number of grinding disc bases 42, grinding discs 40, and fixtures 30. By separating each set of workstations independently, different states of each workpiece 90 can be accommodated. The grinding disc base 42 is mounted on the second slide rails 411 and can be moved up and down via a grinding disc slider 421. The grinding disc base 42 and the grinding disc slider 421 are fixed together by threads.

[0033] A connecting rod 422 extends from the bottom of the grinding disc slider 421 along the direction close to the first base 41. The first base 41 is provided with a plurality of first through holes 412, and the grinding disc reset drive mechanism is provided in the corresponding first through hole 412.

[0034] The grinding disc reset drive mechanism includes a traction rope 431, a weight 432, and a guide wheel 433 disposed in the first through hole 412 and guiding the extension direction of the traction rope 431. One end of the traction rope 431 is connected to the connecting rod 422, and the other end passes around the guide wheel 433 and is connected to the weight 432. Specifically, the weight 432 is disposed on one side of the connecting rod 422 and is connected only by the traction rope 431. In this embodiment, the weight 432 can be increased according to actual conditions. When the grinding disc 40 is subjected to downward pressure on the clamp 30 by the second drive mechanism 52, and the pressure is greater than the weight of the weight 432, the weight 432 exerts an upward force on the connecting rod 422 through the traction rope 431, so that the grinding disc 40 abuts against the clamp 30 holding the workpiece 90. The relative distance between the grinding disc 40 and the clamp 30 can be adjusted by the grinding disc reset drive mechanism. The weight 432 applies an upward force to the connecting rod 422 through the traction rope 431, ensuring that the grinding disc 40 presses against the workpiece 90 with appropriate pressure during the grinding process, while the connecting rod 422 does not interfere with the normal rotation of the support beam 44 (which will be described in detail below).

[0035] A second through hole 423 is provided on the grinding disc base 42. A support beam 44 for supporting the grinding disc 40 is provided in the second through hole 423. The support beam 44 is arranged vertically and is located in the second through hole 423 via bearings 45. The bottom of the support beam 44 is provided with a connecting part for transmission connection with the third drive mechanism 53. Preferably, the connecting part is a groove 441 provided at the bottom end of the support beam 44. The third drive mechanism 53 is transmission connected to the connecting part of the support beam 44. The bearings 45 are respectively provided at the upper and lower ends of the second through hole 423. The support beam 44 is installed in the second through hole 423 in a manner that prevents axial movement relative to the second through hole 423 but allows rotation relative to the second through hole 423. The grinding disc 40 is located at the upper end of the support beam 44. When the support beam 44 rotates, the grinding disc 40 and the support beam 44 rotate synchronously. In this embodiment, the fixture base 36 is provided with a corresponding third through hole 363, which can hold multiple fixtures 30. Each fixture 30 is placed in the corresponding third through hole 363, and a grinding disc 40 is provided on the worktable 20 corresponding to each fixture 30.

[0036] Preferably, the fixture also includes a clamp base 36, which includes a first fixed seat 361 and a second fixed seat 362 connected by threads. The second fixed seat 362 is provided with a plurality of third through holes 363, and a rotating body 37 is provided in the third through holes 363 in the vertical direction. The first fixed seat 361 is divided into a first space for the second fixed seat 362 and a second space for the clamp 30 by a partition plate 364. The partition plate 364 is provided with a fourth through hole 365 for connecting the first space and the second space. The bottom of the rotating body 37 passes through the fourth through hole 365 and is connected to the clamp 30.

[0037] Furthermore, the fixture 30 includes a core 31 and a sleeve 32 fitted over the core 31. The core 31 is rod-shaped, and the sleeve 32 is cylindrical. A through hole 311 is provided inside the core 31. Multiple core petals 33 are provided inside the through hole 311, which can slide relative to the through hole 311 and can open and close. The multiple core petals 33 form a clamping space for clamping the workpiece 90. There are 3 to 4 core petals 33. The other end of the through hole 311 of the core 31 away from the core petals 33 is provided with A limiting member 34 that can slide relative to the through hole 311 is fixedly connected to the core lobe 33 by a connecting block. A step 312 is provided at one end of the through hole 311 near the core lobe 33. An elastic member 35 is formed between the bottom of the limiting member 34, the step 312 and the sidewalls of each core lobe 33, which can press against the limiting member 34 and open the multiple core lobe 33 to unlock the workpiece 90. The two ends of the elastic member 35 are fixedly connected to the limiting member 34 and the step 312 respectively. In use, by applying a downward force to the rotating body 37, the rotating body 37 moves downward to press against the limiting member 34, causing the limiting member 34 and each core lobe 33 to move downward along the through hole 311, thereby opening the core lobe 33. After the workpiece 90 to be processed is placed in, the force applied to the rotating body 37 is removed, and the elastic member 35 restores its elasticity, pressing the limiting member 34 upward, causing the core lobe 33 to move upward along the through hole 311, causing the core lobe 33 to close and clamp the workpiece 90. The lower end of the core body 31 is positioned corresponding to the grinding disc 40, and the workpiece 90 extends into the grinding disc 40 for grinding. The fixture 30 in this embodiment has the advantages of simple structure and convenient assembly and disassembly of the workpiece 90. In addition to being used in the grinding machine described above, it can also be used in grinding machines with other structures.

[0038] Furthermore, the rotating body 37 and the clamping sleeve 32 are connected by a ball joint. The bottom of the rotating body 37 is provided with a ball joint connecting rod 371, and the upper end of the clamping sleeve 32 is provided with a ball joint seat 321. The ball joint connecting rod 371 is fitted into the ball joint seat 321 with a gap between them. Through the first drive mechanism 51, the second drive mechanism 52, and the third drive mechanism 53, the ball joint connection enables the clamping fixture 30 to drive the workpiece 90 to rotate in multiple directions in the second space, thereby performing multi-directional grinding with the contact surface of the grinding groove 401.

[0039] Preferably, the core 31 has an outer conical surface at one end of the core lobe 33 corresponding to the through hole 311, and the core 31 has an inner conical surface. Through the cooperation of the inner and outer conical surfaces, the axial movement of the core 31 is converted into the force on the circumferential surface of the core 31, thereby realizing the closing and opening of the core lobe 33.

[0040] Furthermore, cooling water nozzles (not shown in the figure) are installed on the frame 10 corresponding to the grinding disc 40. The cooling water nozzles are connected to a water source, and multiple cooling water nozzles are provided on the cooling water distribution plate. The cooling water cools the workpiece 90 and the grinding disc 40 on one hand, and washes away the powder in the grinding disc 40 on the other hand.

[0041] Furthermore, the third drive mechanism 53 includes a second motor 531 mounted on the frame 10 and a drive shaft 532 rotatably mounted on the frame 10. The output shaft of the second motor 531 is connected to the drive shaft 532 via a first transmission belt (not shown in the figure), and the drive shaft 532 is connected to the groove 441 of the connecting part via a second transmission belt (not shown in the figure).

[0042] In use, each workpiece 90 to be ground is clamped on the core lobe 33 of the fixture 30. The second drive mechanism 52 moves it downwards to press the workpiece 90 onto the grinding groove 401 of the grinding disc 40 with a spherical R-degree surface under a certain pressure. The first drive mechanism 51 drives the fixture 30 to move horizontally, and the third drive mechanism 53 drives the grinding disc 40 to rotate at a certain speed. The workpiece 90 swings at a certain angle around the center of the spherical R-degree surface of the grinding disc. During the grinding process, cutting fluid or water is required for lubrication and cooling. This embodiment also has an automatic sensing device. When one side of the workpiece 90 is ground into a qualified spherical surface within a specified time, the program will automatically stop to avoid over-grinding and affecting the yield.

[0043] By adopting the aforementioned design scheme, the beneficial effects of this utility model are as follows: the first driving mechanism 51 and the second driving mechanism 52 drive the workpiece 90 on the clamp 30 to move, and the third driving mechanism 53 drives the grinding disc 40 to rotate and grind the workpiece 90. When the grinding disc 40 is subjected to downward pressure by the clamp 30, and the pressure is greater than the weight of the weight 432, the weight 432 applies an upward force to the connecting rod 433 through the traction rope 431, so that the grinding disc 40 abuts against the clamp 30 holding the workpiece 90. The entire process does not require manual reset of the grinding disc; this utility model can automatically reset, saving manpower and improving work efficiency.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
