[0001] This utility model relates to the field of auxiliary equipment for mechanical processing, and specifically to an abrasive flow fixture for tubular parts that is easy to disassemble. Background Technology

[0002] In the machining of tubular parts, abrasive flow machining technology is widely used for polishing, deburring, and precision dimensional finishing of the inner wall of tubular parts. In abrasive flow machining, the fixture plays a crucial role. It needs to firmly fix the tubular parts to ensure that the abrasive flow can act evenly and effectively on the inner wall of the parts.

[0003] Traditional abrasive flow fixtures for tubular parts have many problems: on the one hand, the structural design of the fixture is not reasonable enough, and the operation of installing and disassembling tubular parts is cumbersome, which consumes a lot of time and manpower; on the other hand, the existing fixtures have poor versatility and can often only clamp and fix tubular parts of specific sizes and specifications, which makes it difficult to meet the diverse processing needs of tubular parts. Summary of the Invention

[0004] The purpose of this invention is to provide an easily disassembled abrasive flow fixture for tubular parts, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A detachable abrasive flow fixture for tubular parts includes a base, a transmission chamber on the inner side of the base, two sets of clamps slidably connected to the top of the base, a drive mechanism on the inner side of the transmission chamber to facilitate the reverse movement of the two sets of clamps, a clamping block connected to one side of each set of clamps via a snap-fit ​​mechanism for easy disassembly and assembly, a groove adapted to the tubular part on one side of the clamping block, a placement groove at the center of the top of the base, and a guide tube for facilitating the flow of abrasive particles connected to the bottom of the placement groove.

[0007] Using the above technical solution, the two sets of clamps can be driven to move in opposite directions by the drive mechanism, so as to realize the clamping and quick disassembly of tubular parts. Through the set snap-fit ​​mechanism, the quick disassembly and replacement of clamps of different specifications can be realized.

[0008] A further improvement of this utility model is that: the driving mechanism includes an electric push rod; the inner side of the transmission chamber is provided with two sets of support rods and slidably connected with two sets of movable seats; one side of each set of movable seats is provided with a rack plate; both sets of rack plates mesh with a spur gear; the spur gear is sleeved on the outer ring of the fixed cylinder; the fixed cylinder is located inside the transmission chamber and sleeved on the outer ring of the guide cylinder; the top ends of the two sets of movable seats are respectively connected to the bottom of the corresponding clamps; the bottom of one set of movable seats is provided with a connecting block; one side of the connecting block is connected to one end of the electric push rod installed inside the transmission chamber.

[0009] Using the above technical solution, the telescopic movement of the electric push rod can realize the opposite movement of the two sets of clamps on the top of the base, so as to facilitate the quick clamping and disassembly of tubular parts.

[0010] A further improvement of this utility model is that: one side of each of the two sets of movable seats is provided with a through groove to facilitate the movement of the rack plate.

[0011] Using the above technical solution, the through groove can reserve sufficient space for the rack plate to move.

[0012] A further improvement of this utility model is that: the locking mechanism includes a locking ball and a locking groove; a sleeve is passed through both ends of the clamping block; one end of the sleeve is provided with a plug-in cylinder; the other end of the sleeve has a movable cavity; a slide rod is slidably connected to the inner side of the movable cavity; one end of the slide rod is connected to a button slidably connected to the inner side of the movable cavity; the button is connected to the movable cavity through a spring sleeved on the outer ring of the slide rod; the other end of the slide rod is connected to an abutment seat passing through the inner side of the plug-in cylinder; two sets of storage slots are symmetrically opened on the inner wall of the plug-in cylinder, and the locking ball that abuts against the abutment seat is placed therein; two sets of locking grooves are correspondingly opened on one side of the clamping seat, each adapted to one of the two sets of plug-in cylinders.

[0013] The above technical solution, through this snap-fit ​​mechanism design, facilitates the quick replacement of clamping blocks of different specifications, making it suitable for clamping tubular parts of different specifications.

[0019] The above technical solution allows for convenient installation and fixation of the base through mounting holes.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] 1. This utility model provides an easily disassembled abrasive flow clamp for tubular parts. By activating the electric push rod, its extension or retraction can drive the connecting block and the connected moving seat to move. By observing the position of the clamping seats, the two sets of clamping seats are adjusted to a position where the distance between them is greater than the diameter of the tubular part to be processed, so as to place the part later. After the tubular part is placed stably, the electric push rod is activated again, so that its movement direction is opposite to the previous step, thereby driving the two sets of moving seats to move towards each other. The two sets of clamping seats move with the moving seats until the groove on the clamping block is tightly attached to the outer wall of the tubular part, thus firmly clamping the tubular part. By reversing the operation, the tubular part can be quickly released. Thus, the design greatly improves the convenience of disassembling and assembling tubular parts.

[0022] 2. This utility model provides an easily disassembled abrasive flow fixture for tubular parts. Through the set snap-fit ​​mechanism, the corresponding specification of the clamping block can be quickly replaced according to the tubular parts of different diameters, thereby greatly improving the applicability of the fixture.

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1

[0033] As shown in Figures 1-6, this utility model provides a tubular part abrasive flow fixture that is easy to disassemble, including a base 1, a transmission chamber 3 is provided on the inner side of the base 1, two sets of clamping seats 6 are slidably connected to the top of the base 1, a drive mechanism is provided on the inner side of the transmission chamber 3 to facilitate the reverse movement of the two sets of clamping seats 6, a clamping block 7 is connected to one side of each of the two sets of clamping seats 6 through a snap-fit ​​mechanism that is easy to disassemble and assemble, a groove 8 adapted to the tubular part is provided on one side of the clamping block 7, a placement groove 26 is provided at the center of the top of the base 1, and a guide tube 27 that facilitates the flow of abrasive particles is connected to the bottom of the placement groove 26.

[0034] In this embodiment, the base 1 serves as the foundation of the entire fixture, providing an installation and support platform for other components. Through the provided drive mechanism, the two sets of clamping seats 6 can move in opposite directions, facilitating the quick clamping and disassembly of tubular parts. Through the provided snap-fit ​​mechanism, the clamping blocks 7 of the corresponding specifications can be quickly replaced according to tubular parts of different diameters. Thus, through the above structure, the ease of disassembling and assembling tubular parts is improved, while the applicability of the fixture is enhanced, meeting the processing needs of diverse tubular parts.

[0035] As shown in Figures 1-6, preferably, the drive mechanism includes an electric push rod 13. Two sets of support rods 4 are provided inside the transmission chamber 3, and two sets of movable seats 5 are slidably connected to them. Each set of movable seats 5 has a rack plate 9 on one side, and both rack plates 9 mesh with a spur gear 10. The spur gear 10 is sleeved on the outer ring of a fixed cylinder 11. The fixed cylinder 11 is located inside the transmission chamber 3 and sleeved on the outer ring of the guide cylinder 27. The top ends of the two sets of movable seats 5 are respectively connected to the bottom of corresponding clamps 6. One set of movable seats 5 has a connecting block 12 at its bottom, and one side of the connecting block 12 is connected to one end of the electric push rod 13 installed inside the transmission chamber 3. The electric push rod 13 is activated... When it extends or shortens, it can drive the connecting block 12 and the connected moving seat 5 to move. By observing the position of the clamping seat 6, the two sets of clamping seats 6 are adjusted to a position where the distance between them is greater than the diameter of the tubular part to be processed, so that the part can be placed later. After the tubular part is placed stably, the electric push rod 13 is started again, so that its movement direction is opposite to the previous step, thereby driving the two sets of moving seats 5 to move towards each other. The two sets of clamping seats 6 move with the moving seats 5 until the groove 8 on the clamping block 7 is tightly attached to the outer wall of the tubular part, so that the tubular part can be firmly clamped. By reversing the operation, the tubular part can be quickly released. Thus, by setting it up, the ease of disassembly and assembly of the tubular part is greatly improved.

[0036] As shown in Figures 1-6, preferably, each of the two sets of movable seats 5 has a corresponding through groove 14 on one side to facilitate the movement of the rack plate 9. The through groove 14 can reserve enough space for the rack plate 9 to move.

[0037] As shown in Figures 1-6, preferably, the locking mechanism includes a locking ball 23 and a locking groove 24. Sleeves 15 penetrate the clamping block 7 near both ends. One end of the sleeve 15 has a connector 16, and the other end has a movable cavity 17. A sliding rod 18 is slidably connected to the inner side of the movable cavity 17. One end of the sliding rod 18 is connected to a button 19 slidably connected to the inner side of the movable cavity 17. The button 19 is connected to the movable cavity 17 via a spring 20 sleeved on the outer ring of the sliding rod 18. The other end of the sliding rod 18 is connected to an abutment seat 21 penetrating the inner side of the connector 16. Two sets of receiving slots 22 are symmetrically formed on the inner wall of the connector 16, each containing a locking ball 23 that abuts against the abutment seat 21. Two sets of locking grooves 24, each adapted to one set of connectors 16, are correspondingly formed on one side of the clamping seat 6. By pressing the button 19, the button 19 can drive the sliding rod 18 to one side. While sliding to the side, button 19 can compress spring 20. As slide rod 18 slides, it can drive contact seat 21 to move to one side. After contact seat 21 moves, the two sets of retaining balls 23 can lose their contact and be stored inside the storage groove 22. Then, insert the connector 16 into the slot 24. Then, by releasing button 19, under the reaction force of spring 20, button 19 can drive slide rod 18 and contact seat 21 to move in the opposite direction. Contact seat 21 can squeeze the two sets of retaining balls 23 outward from the storage groove 22, so that the two sets of retaining balls 23 can engage with slot 24, thereby completing the installation and fixing of clamp 7. By reversing the operation, clamp 7 can be disassembled. Furthermore, by setting, clamp 7 of the corresponding specification can be quickly replaced according to tubular parts of different diameters, greatly improving the applicability of the fixture.

[0038] As shown in Figures 1-6, preferably, both ends of the clamping block 7 are provided with slots 25, which facilitate the disassembly and assembly of the clamping block 7.

[0039] As shown in Figures 1-6, preferably, the surface of the groove 8 is provided with an anti-slip pad. The anti-slip pad can increase the friction between the clamping block 7 and the tubular part, prevent the part from sliding during processing, and avoid scratching the surface of the part.

[0040] As shown in Figures 1-6, preferably, two sets of mounting holes 2 are provided at both ends of the base 1. The mounting holes 2 facilitate the installation and fixation of the base 1.

[0041] The working principle of this fixture will be explained in detail below.

[0042] As shown in Figures 1-6, firstly, by activating the electric push rod 13, when it extends or retracts, it can drive the connecting block 12 and the connected moving seat 5 to move. The two sets of clamps 6 and clamping blocks 7 can move accordingly. By observing the position of the clamps 6, the two sets of clamps 6 are adjusted to a position where the distance between them is greater than the diameter of the tubular part to be processed, so that the part can be placed later. After the tubular part is placed stably, the electric push rod 13 is activated again, so that its direction of action is opposite to the previous step, thereby driving the two sets of moving seats 5 to move towards each other. The two sets of clamps 6 move with the moving seats 5 until the groove 8 on the clamping block 7 tightly fits the outer wall of the tubular part, thus firmly clamping the tubular part. By reversing the operation, the tubular part can be quickly released.

[0043] When it is necessary to disassemble or assemble the clamping block 7, by pressing button 19, button 19 can drive slide rod 18 to one side. At the same time, button 19 can compress spring 20. As slide rod 18 slides, it can drive contact seat 21 to one side. After contact seat 21 moves, the two sets of locking balls 23 can lose their abutting effect and be placed inside the storage slot 22. Then, insert the connector 16 into the slot 24. Then, by releasing button 19, under the reaction force of spring 20, button 19 can drive slide rod 18 and contact seat 21 to move in the opposite direction. Contact seat 21 can squeeze the two sets of locking balls 23 outward from the storage slot 22, so that the two sets of locking balls 23 can engage with slot 24, thereby completing the installation and fixing of clamping block 7. By reversing the operation, clamping block 7 can be disassembled, thus completing the entire operation process.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
