Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to a cup body polishing fixture. Background Art

[0002] Polishing is an essential process in the production process of tapered cups. The existing polishing operation process is to clamp and rotate the cup with a fixture, and then use a polishing tool to perform the polishing operation.

[0003] The existing clamp generally includes a fixed clamping end and a movable clamping end. The movable clamping end moves back and forth toward the fixed clamping end so that the fixed clamping end and the movable clamping end respectively abut against the bottom and the mouth of the cup body. The cup body is clamped and held by the clamping force of the fixed clamping end and the movable clamping end, and then the fixed clamping end drives the cup body and the movable clamping end to rotate together. However, in the actual production process, the cup body is always in a high-speed rotation state, and the polishing equipment also needs to give the cup body a certain extrusion pressure, which causes the cup body to slip or rub slightly during the polishing process, affecting the polishing quality. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing clamping stability is not high, which easily causes slight slippage or friction of the cup body and affects the polishing quality.

[0005] In order to solve the above technical problems, the utility model provides a technical solution: a cup body polishing fixture, comprising a base, a cup mouth clamping end and a cup bottom clamping end arranged on the base, wherein the cup mouth clamping end and the cup bottom clamping end are both slidably arranged on the base through a slide rail, and the two clamping ends are driven to reciprocate simultaneously by a clamping driving mechanism arranged between the two slide rails;

[0006] When the two clamping ends clamp the cup, at least one of the two clamping ends drives the cup and the other clamping end to rotate together under the action of the rotary drive mechanism;

[0007] Both clamping ends are provided with ejection mechanisms capable of ejecting the cup when the cup is released from clamping, and the cup bottom clamping end is provided with a vacuum generator interface for vacuum adsorbing the cup bottom.

[0008] Furthermore, the clamping drive mechanism includes a rack, a gear and a clamping drive cylinder, the two racks are arranged on opposite sides of the groove of the base, the gear is arranged between the two racks and meshes with them, one end of one rack is fixedly connected to the clamping end of the cup mouth, and the other end of the other rack is fixedly connected to the clamping end of the cup bottom, one end of the clamping drive cylinder is hinged to the base, and the other end is connected to the clamping end of the cup mouth.

[0009] Furthermore, a sliding block is provided on the base of the cup mouth clamping end, and a buffer is provided on the sliding block.

[0010] Furthermore, the cup mouth clamping end includes a cup mouth fixing plate, a cup mouth rotating shaft, a cup mouth end face fixing seat and a cup mouth tapered top head, one end of the cup mouth rotating shaft is connected to a rotating drive mechanism arranged on the cup mouth fixing plate, and the other end is connected to the cup mouth end face fixing seat after passing through the cup mouth fixing plate through a bearing, the cup mouth tapered top head cover is arranged at the end of the cup mouth end face fixing seat and forms a cavity for placing the pop-up mechanism, one end of the pop-up mechanism is connected to the cup mouth end face fixing seat, and the other end is connected to the cup mouth tapered top head.

[0011] Furthermore, a dust ring is arranged in the sliding gap between the cup mouth taper head and the cup mouth end surface fixing seat.

[0012] Furthermore, the cup bottom clamping end includes a cup bottom fixing plate, a cup bottom rotating shaft, a cup bottom end face guide seat and a suction cup. The cup bottom rotating shaft is a hollow shaft, one end of which is connected to the vacuum generator interface, and the other end of which passes through the cup bottom fixing plate through a bearing and is connected to the cup bottom end face guide seat. The suction cup is slidably embedded in the end of the cup bottom end face guide seat and forms a chamber for placing the pop-up mechanism. One end of the pop-up mechanism is connected to the cup bottom end face guide seat, and the other end is connected to the suction cup.

[0013] Furthermore, a sealing ring is provided in the sliding gap between the suction cup and the cup bottom end surface guide seat.

[0014] Furthermore, the pop-up mechanism includes a spring, a sliding sleeve and a sliding pin, the spring sleeve is arranged at one end of the sliding pin, and the sliding sleeve is sleeved on the other end of the sliding pin and connected to the cup mouth end surface fixing seat and the cup bottom end surface guide seat, and one end of the sliding pin and the spring end are restricted in the sliding sleeve.

[0015] Furthermore, the rotary drive mechanism includes a rotary drive motor, a right-angle star reducer, a driving wheel, a driven wheel and a synchronous belt. The power shaft of the rotary drive motor is connected to the input shaft of the right-angle star reducer and is arranged at the bottom of the cup mouth fixing plate. The driving wheel is connected to the output shaft of the right-angle star reducer. The driven wheel is connected to one end of the cup mouth rotating shaft through a retracted nut. The driven wheel and the driving wheel are linked by a synchronous belt that passes through the groove on the base.

[0016] The beneficial effects of the utility model are:

[0017] 1. This application realizes that both clamping ends can move on the base through the action of the cup mouth clamping end, the cup bottom clamping end, the clamping drive mechanism and the rotation drive mechanism to ensure the stability of clamping. At the same time, the vacuum formed by the cup bottom clamping end adsorbs the bottom of the cup body to ensure the connection stability, thereby solving the problem of cup body sliding during polishing and improving product quality.

[0018] 2. In the present application, the two clamping ends move back and forth simultaneously under the action of the clamping drive mechanism, that is, move toward and away from each other, to achieve rapid clamping and releasing operations, and both clamping ends exert active clamping force to increase clamping stability. At the same time, since both clamping ends are provided with a pop-up mechanism, the cup body can be automatically popped out, which is convenient for taking and reduces collision with the clamping ends.

[0019] 3. In the present application, two racks clamp and mesh with the gears. Since the opposite ends of the two racks are respectively connected to the cup mouth clamping end and the cup bottom clamping end, when the clamping drive cylinder pushes the cup mouth clamping end to move, the cup mouth clamping end drives one rack to move and drives the gear to rotate, and the gear drives the other rack to move, thereby realizing the synchronous movement of the cup bottom clamping end. This structure has high stability and precision. At the same time, the movement shortens the stroke of the clamping drive cylinder and shortens the clamping and release time.

[0020] 4. In this application, the sliding block blocks the track so that the cup mouth clamping end is always kept between the sliding block and the clamping drive cylinder to prevent the cup mouth clamping end from accidentally falling off. The use of the buffer turns the hard contact into flexible contact, reducing the chance of collision damage.

[0021] 5. In the present application, the cup mouth fixing plate is fixedly set on the slide rail to realize reciprocating movement. The cup mouth rotating shaft can drive the cup mouth end face fixing seat and the cup mouth tapered head to rotate together under the action of the rotating drive mechanism. Since the cup mouth tapered head has a taper and a diameter smaller than the cup mouth end face fixing seat, a stop platform is formed. The cup mouth tapered head can extend into the cup mouth. After the cup mouth tapered head retracts and compresses the spring, it cooperates with the stop platform to limit the cup body to ensure the stability of the cup body clamping. When the clamping operation is released, the spring resets, thereby pushing the cup mouth tapered head to move outward and reset, and the cup body is automatically ejected; at the same time, since the cup mouth tapered head and the cup mouth end face fixing seat are slidably connected, the dustproof ring is set between them to increase the sealing performance to prevent external debris from entering and affecting the performance of the spring.

[0022] 6. In the present application, the cup bottom fixing plate is fixedly arranged on the slide rail to realize reciprocating movement. The cup bottom rotating shaft can drive the cup bottom end face guide seat and the suction cup to rotate together under the action of the cup body. The end of the cup bottom end face guide seat is trumpet-shaped, which is convenient for the cup bottom to be embedded. Since the cup bottom rotating shaft is a hollow shaft and it is connected to the vacuum generator interface, the suction cup can be fixedly adsorbed on the cup bottom, the stability of the cup body clamping is increased, and the displacement during polishing affects the polishing quality. At the same time, due to the existence of the pop-up mechanism, it plays the role of an adsorption switch. After the cup body compresses the suction cup press-in spring, the vacuum generator interface is connected to the suction cup for adsorption operation. When the cup body is released from the clamping operation, the spring resets to pop the cup body out and block the vacuum generator interface. Since the suction cup and the cup bottom end face guide seat are slidably connected, the sealing ring is set between them to increase the sealing, prevent external debris from entering and affecting the performance of the spring, and also prevent air leakage from affecting the suction force of the suction cup.

[0023] 7. In the present application, one end of the sliding pin is embedded in the spring, and the sliding sleeve is sleeved on the other end of the sliding pin. After the sliding sleeve is connected to the cup mouth end surface fixing seat and the cup bottom end surface guide seat, the sliding pin and the spring end are restricted in the sliding sleeve, and the end of the sliding pin is connected to the cup mouth tapered top and the suction cup, so that the reciprocating movement of the cup mouth tapered top and the suction cup is realized under the action of the spring, and when the spring in the cup bottom clamping end is in an extended state, the end of the sliding pin blocks the hollow of the cup bottom rotating shaft, and the suction cup has no suction force. When the sliding pin moves and compresses the spring, the end of the sliding pin releases the sealing of the hollow of the cup bottom rotating shaft, so that the suction cup has suction force.

[0024] 8. In the present application, the rotary drive mechanism is arranged on the cup mouth fixing plate and is located on the lower side of the base, and can move with the cup mouth clamping end. The synchronous belt passes through the groove on the base and does not interfere with each other during movement. The structure is simple and easy to use.

[0038] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0039] The names of the messages or information exchanged between multiple devices in the implementation manner of the present utility model are only used for illustrative purposes, and are not used to limit the scope of these messages or information. Example 1

[0040] like Figure 1-4 As shown, a cup body polishing fixture comprises a base 1, a cup mouth clamping end 2 and a cup bottom clamping end 3 arranged on the base 1, the cup mouth clamping end 2 and the cup bottom clamping end 3 are both slidably arranged on the base 1 through a slide rail 4, and the two clamping ends are driven to reciprocate simultaneously by a clamping driving mechanism 5 arranged between the two slide rails 4;

[0041] The clamping drive mechanism 5 includes a rack 51, a gear 52 and a clamping drive cylinder 53. The two racks 51 are arranged on opposite sides of the groove 6 of the base 1. The gear 52 is arranged between the two racks 51 and meshes with them. One end of one rack 51 is fixedly connected to the cup mouth clamping end 2, and the other end of the other rack 51 is fixedly connected to the cup bottom clamping end 3. One end of the clamping drive cylinder 53 is hinged to the base 1, and the other end is connected to the cup mouth clamping end 2. The two racks 51 are connected to the gear 52. The two racks 51 are clamped and meshed. Since the opposite ends of the two racks 51 are respectively connected to the cup mouth clamping end 2 and the cup bottom clamping end 3, when the clamping drive cylinder 53 pushes the cup mouth clamping end 2 to move, the cup mouth clamping end 2 drives one rack 51 to move and drives the gear 52 to rotate, and the gear 52 drives the other rack 51 to move, thereby realizing the synchronous movement of the cup bottom clamping end 3. This structure has high stability and precision. At the same time, the movement shortens the stroke of the clamping drive cylinder 53 and shortens the clamping and releasing time.

[0042] The cup mouth clamping end 2 includes a cup mouth fixing plate 21, a cup mouth rotating shaft 22, a cup mouth end surface fixing seat 23 and a cup mouth taper head 24. One end of the cup mouth rotating shaft 22 is connected to the rotation drive mechanism 8 arranged on the cup mouth fixing plate 21, and the other end passes through the cup mouth fixing plate 21 through the bearing 7 and is connected to the cup mouth end surface fixing seat 23. The cup mouth taper head 24 is covered at the end of the cup mouth end surface fixing seat 23 and forms a chamber for placing the ejection mechanism 9. One end of the ejection mechanism 9 is connected to the cup mouth end surface fixing seat 23, and the other end is connected to the cup mouth taper head 24. The cup mouth fixing plate 21 is fixedly arranged on the slide rail 4. On, thereby realizing reciprocating movement, the cup mouth rotating shaft 22 can drive the cup mouth end face fixing seat 23 and the cup mouth tapered head 24 to rotate together under the action of the rotating drive mechanism 8. Since the cup mouth tapered head 24 has a taper and a diameter smaller than the cup mouth end face fixing seat 23, a stop platform is formed, and the cup mouth tapered head 24 can extend into the cup mouth. After the cup mouth tapered head 24 retracts and compresses the spring 91, it cooperates with the stop platform to limit the cup body to ensure the stability of the cup body clamping. When the clamping operation is released, the spring 91 is reset, thereby pushing the cup mouth tapered head 24 to move outward and reset, and the cup body is automatically ejected.

[0043] Among them, the cup bottom clamping end 3 includes a cup bottom fixing plate 31, a cup bottom rotating shaft 32, a cup bottom end face guide seat 33 and a suction cup 34. The cup bottom rotating shaft 32 is a hollow shaft, one end of which is connected to the vacuum generator interface 35, and the other end of which passes through the cup bottom fixing plate 31 through a bearing 7 and is connected to the cup bottom end face guide seat 33. The suction cup 34 is slidably embedded in the end of the cup bottom end face guide seat 33 and forms a chamber for placing the pop-up mechanism 9. One end of the pop-up mechanism 9 is connected to the cup bottom end face guide seat 33, and the other end is connected to the suction cup 34; the cup bottom fixing plate 31 is fixedly set on the slide rail 4 to realize reciprocating movement, and the cup bottom rotating shaft 32 can drive the cup bottom end face guide seat 33 under the action of the cup body. The guide seat 33 and the suction cup 34 rotate together, and the end of the cup bottom end face guide seat 33 is trumpet-shaped, which is convenient for the cup bottom to be embedded. Since the cup bottom rotating shaft 32 is a hollow shaft and it is connected to the vacuum generator interface 35, the suction cup 34 can be fixedly adsorbed to the cup bottom, thereby increasing the stability of the cup body clamping and preventing displacement during polishing that affects the polishing quality. At the same time, due to the existence of the pop-up mechanism 9, it plays the role of an adsorption switch. After the cup body compresses the suction cup 34 press-in spring 91, the vacuum generator interface 35 is connected to the suction cup 34 to perform the adsorption operation. When the cup body is released from the clamping operation, the spring 91 resets to pop the cup body out and blocks the vacuum generator interface 35.

[0044] When the two clamping ends clamp the cup, at least one of the two clamping ends drives the cup and the other clamping end to rotate together under the action of the rotating drive mechanism 8; wherein the rotating drive mechanism 8 includes a rotating drive motor 81, a right-angle star reducer 82, a driving wheel 83, a driven wheel 84 and a synchronous belt, the power shaft of the rotating drive motor 81 is connected to the input shaft of the right-angle star reducer 82, and is arranged at the bottom of the cup mouth fixing plate 21, the driving wheel 83 is connected to the output shaft of the right-angle star reducer 82, the driven wheel 84 is connected to one end of the cup mouth rotating shaft 22 through the retracting nut 36, and the driven wheel 84 and the driving wheel 83 are linked by a synchronous belt that passes through the groove 6 on the base; the rotating drive mechanism 8 is arranged on the cup mouth fixing plate 21, and is on the lower side of the base 1, and can move with the cup mouth clamping end 2, the synchronous belt passes through the groove 6 on the base 1, and does not interfere with each other when moving, the structure is simple, and it is easy to use.

[0045] Among them, both clamping ends are provided with an ejection mechanism 9 that can eject the cup when the cup is released, and the cup bottom clamping end 3 is provided with a vacuum generator interface 35 for vacuum adsorption of the cup bottom; the ejection mechanism 9 includes a spring 91, a sliding sleeve 93 and a sliding pin 92, the spring 91 is sleeved on one end of the sliding pin 92, the sliding sleeve 93 is sleeved on the other end of the sliding pin 92 and connected to the cup mouth end surface fixing seat 23 and the cup bottom end surface guide seat 33, and one end of the sliding pin 92 and the spring 91 end are restricted in the sliding sleeve 93; one end of the sliding pin 92 is embedded in the spring 91, and the sliding sleeve 93 is sleeved on the other end of the sliding pin 92. After the sleeve 93 is connected to the cup mouth end surface fixing seat 23 and the cup bottom end surface guide seat 33, the sliding pin 92 and the end of the spring 91 are restricted in the sliding sleeve 93, and the end of the sliding pin 92 is connected to the cup mouth tapered top 24 and the suction cup 34, so that the reciprocating movement of the cup mouth tapered top 24 and the suction cup 34 is realized under the action of the spring 91, and when the spring 91 in the cup bottom clamping end 3 is in an extended state, the end of the sliding pin 92 blocks the hollow of the cup bottom rotating shaft 32, and the suction cup 34 has no suction force. When the sliding pin 92 moves to compress the spring 91, the end of the sliding pin 92 releases the hollow of the cup bottom rotating shaft 32 for blocking, so that the suction cup 34 has suction force. Example 2

[0046] like Figure 1-4 As shown, this embodiment is obtained by adding technical features such as a sliding stopper 10 on the basis of the first embodiment. The remaining technical features are the same as those of the first embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the first embodiment is that a sliding stopper 10 is provided on the base 1 of the cup mouth clamping end 2, and a buffer 11 is provided on the sliding stopper 10.

[0047] In this embodiment, the sliding block 10 blocks the track so that the cup mouth clamping end 2 is always maintained between the sliding block 10 and the clamping drive cylinder 53 to prevent the cup mouth clamping end 2 from accidentally falling off. The use of the buffer 11 changes the hard contact into flexible contact, reducing the chance of collision damage. Example 3

[0048] like Figure 2 As shown, this embodiment is obtained by adding technical features such as a dust ring 25 on the basis of the second embodiment. The remaining technical features are the same as those of the second embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the second embodiment is that a dust ring 25 is arranged in the sliding gap between the cup mouth taper head 24 and the cup mouth end face fixing seat 23.

[0049] In this embodiment, since the cup mouth taper head 24 and the cup mouth end surface fixing seat 23 are slidably connected, the dust ring 25 is provided between them to increase the sealing performance and prevent foreign matter from entering and affecting the performance of the spring 91. Example 4

The remaining technical features are the same as those of the third embodiment, and the similarities are not repeated here. Among them, the difference between this embodiment and the third embodiment is that a sealing ring 36 is provided in the sliding gap between the suction cup 34 and the cup bottom end face guide seat 33.

[0051] In this embodiment, since the suction cup 34 and the cup bottom end face guide seat 33 are slidably connected, the setting of the sealing ring 36 between them increases the sealing performance, prevents foreign matter from entering and affecting the performance of the spring 91, and also prevents air leakage from affecting the suction force of the suction cup 34.

It is connected to the suction cup 34, the cup mouth of the cup body is against the cup mouth end surface fixing seat 23, and the cup bottom of the cup body is adsorbed on the suction cup 34. The rotation drive mechanism 8 drives the cup mouth rotating shaft 22, the cup bottom rotating shaft 32 and the cup body to rotate together, and then the polishing operation is performed. After that, the clamping drive cylinder 53 is reset, the cup mouth clamping end 2 and the cup bottom clamping end 3 move away from each other to release the clamping of the cup body, and the spring 91 in the pop-up mechanism 9 is reset, and drives the cup mouth taper head 24 and the suction cup 34 to reset, and the cup body is ejected.
