TECHNICAL FIELD
[0001] The utility model relates to the technical field of fixture, specifically, relates to a fixed clamp for end cover drilling. BACKGROUND
[0002] In the field of mechanical processing, the drilling operation of the end cover is a common process link. In the traditional end cover drilling process, the end cover is usually fixed by manual holding. However, it is difficult to ensure the stability of the drilling process by manually holding the end cover, which can easily lead to the deviation of the drilling position or the damage of the end cover.
[0003] In order to solve the above problems, people designed a fixed clamp, and then the structure of such clamp is complex, the operation is cumbersome, and it is not convenient for operators to operate. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a fixed clamp for end cover drilling, which pushes the clamping seat through the design of the push-pull assembly, so that the clamping seat is close to the placement table and clamps the end cover, ensuring that the end cover can remain stable during drilling, and the structure is simple and easy to operate.
[0005] A fixed clamp for end cover drilling, comprising a base, a placement table for placing an end cover is fixedly installed on the base, clamping seats are arranged on both sides of the placement table, the clamping seats slide on the base along the direction close to or away from the placement table through a push-pull assembly, the clamping seat comprises a bearing block, a groove is arranged on the side of the bearing block close to the placement table, and the groove wall of the groove is matched with the outer circumferential surface of the end cover when the two clamping seats are close to the placement table and closed.
[0006] In the above technical solution, the placement table is arranged on the base to facilitate the operator to quickly position the placement position of the end cover. The clamping seat is arranged on both sides of the placement table and slides on the base through the push-pull assembly. The clamping seat comprises a bearing block, and a groove is arranged on the side of the bearing block close to the placement table. When the two clamping seats are close to the placement table and closed through the push-pull assembly, the groove wall of the groove is matched with the outer circumferential surface of the end cover to clamp the end cover. After clamping the end cover, the operator can perform the drilling operation. Due to the cooperation of the clamping seat and the placement table, the end cover can remain stable during the drilling process and will not move or deform due to vibration or improper operation. After completing the drilling operation, the operator slides the clamping seat along the base away from the placement table through the operation of the push-pull assembly, so as to release the clamped end cover. The fixed clamp for end cover drilling provided by the utility model pushes the clamping seat through the design of the push-pull assembly, so that the clamping seat is close to the placement table and clamps the end cover, ensuring that the end cover can remain stable during drilling, and the structure is simple and easy to operate.
[0007] Further, the clamp base further comprises a positioning plate, the positioning plate is located above the abutting block, at least part of the positioning plate is opposite to the groove, and the part of the positioning plate opposite to the groove is provided with at least one positioning hole.
[0008] In the above technical solution, the positioning plate and the positioning hole thereon provide additional guiding and positioning functions for the end cover. When the clamp base is close to the placement table and is closed, the positioning hole is opposite to the end cover, and an operator can determine the drilling position of the end cover through the positioning hole, thereby reducing drilling errors caused by position deviation.
[0009] Further, the clamp base further comprises a positioning plate, the positioning plate is located above the abutting block, at least part of the positioning plate is opposite to the groove, and the part of the positioning plate opposite to the groove is provided with at least one positioning hole.
[0010] In the above technical solution, the design of the guiding piece enables the drill bit to drill along a predetermined path, thereby avoiding drilling errors caused by position deviation. This helps to improve drilling precision and product quality.
[0011] Further, the positioning plate is detachably connected to the abutting block through a plurality of fasteners.
[0012] In the above technical solution, the detachable connection between the positioning plate and the abutting block makes the clamp more flexible and easy to maintain. When it is necessary to replace the positioning plate or perform other maintenance operations, the positioning plate can be easily detached and reinstalled.
[0013] Further, a clamping block is arranged between the positioning plate and the abutting block, the clamping block cooperates with the abutting block to form a V-shaped groove, and at least part of the end cover extends into the V-shaped groove.
[0014] In the above technical solution, the design of the V-shaped groove enables the clamping block and the abutting block to jointly clamp the end cover, thereby providing stronger clamping force. This helps to prevent the end cover from shaking or deforming during drilling, thereby improving drilling precision and stability.
[0015] Further, the positioning plate is provided with a plurality of first flow guide grooves, and the first flow guide grooves are uniformly arranged on a side surface of the positioning plate away from the clamping block.
[0016] In the above technical solution, a large amount of heat is generated between the drill bit and the end cover during drilling. In order to maintain normal operation of the drill bit and prolong its service life, it is usually necessary to use a cooling liquid for cooling. When the cooling liquid is used, a part of the cooling liquid will inevitably remain on the positioning plate, and the first flow guide groove can guide the remaining cooling liquid to flow out of the positioning plate.
[0017] Further, a plurality of flow guide openings are arranged at a position of the base close to the placement table.
[0018] In the technical scheme, the cooling liquid used in the drilling process is used not only for cooling the drill bit and the end cover, but also for flushing the drilling area to take away the generated heat and cuttings. The flow guide hole can guide the cooling liquid to flow from the inside of the clamp to the outside, ensuring that the cooling liquid can fully cover the drilling area and improve the cooling effect.
[0019] Further, the base is provided with a sliding groove, and the clamping block is provided with a sliding block on the side facing the base, and the sliding block extends into the sliding groove.
[0020] In the technical scheme, the close cooperation between the sliding groove and the sliding block ensures the stable sliding of the clamping seat on the base, so that the clamping block can accurately clamp the end cover, avoiding the drilling error caused by the shaking or deviation of the end cover.
[0021] Further, the base is provided with a sliding groove, and the clamping block is provided with a sliding block on the side facing the base, and the sliding block extends into the sliding groove.
[0022] In the technical scheme, the communication design of the second flow guide groove and the flow guide hole enables the cooling liquid to flow out of the clamp more smoothly, avoiding the problem of reduced drilling efficiency caused by the accumulation of cooling liquid.
[0023] Further, the second flow guide groove is inclined along the length direction of the base.
[0024] In the technical scheme, the inclined second flow guide groove can ensure that the cooling liquid flows out of the base more smoothly, avoiding the problems of accumulation and blockage.
[0025] Further, the push-pull assembly comprises a push-pull rod and a hand-held part, one end of the push-pull rod is connected with the clamping seat, the other end is connected with the hand-held part, and the push-pull rod cooperates with the hand-held part to drive the clamping seat to approach or move away from the placement table.
[0026] In the technical scheme, when the end cover needs to be clamped, the operator holds the hand-held part and pushes forward to elongate the push-pull rod. The elongation of the push-pull rod will drive the clamping seat to approach the placement table until the clamping mechanism on the clamping seat firmly clamps the end cover on the placement table. When the end cover needs to be released, the operator holds the hand-held part and pulls it back to shorten the push-pull rod. The shortening of the push-pull rod will drive the clamping seat to move away from the placement table, thereby releasing the clamped end cover.
[0027] Compared with the prior art, the end cap drilling fixing clamp has the advantages that: the placing table is arranged on the base, so that the operator can quickly position the placing position of the end cap. The clamping seats are arranged on the two sides of the placing table and slide on the base through the push-pull assembly. The clamping seat comprises the abutting block, and a groove is arranged on the side of the abutting block close to the placing table. When the two clamping seats are close to the placing table and abutted through the push-pull assembly, the groove wall of the groove is matched with the outer circumferential surface of the end cap to abut, so that the end cap is clamped. After the end cap is clamped, the operator can perform the drilling operation. Due to the cooperation of the clamping seat and the placing table, the end cap can keep a stable position during the drilling process and will not move or deform due to vibration or improper operation. After the drilling operation is completed, the operator can slide the clamping seat along the base away from the placing table through the operation of the push-pull assembly, so that the clamped end cap is released. The overall structure is simple and easy to operate. BRIEF DESCRIPTION OF DRAWINGS

[0040] The end cover drilling fixing clamp of the present application will be further described in detail below in conjunction with specific embodiments and drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein.
[0041] Please refer to Figures 1 to 6 In a preferred embodiment, the end cover drilling fixing clamp of the present application comprises a base 1, the base 1 is fixedly installed with a placement table 2 for placing an end cover 5, both sides of the placement table 2 are provided with clamping seats 3, the clamping seats 3 slide on the base 1 in the direction of approaching or moving away from the placement table 2 through a push-pull assembly 4, the clamping seat 3 comprises a bearing block 301, the side of the bearing block 301 close to the placement table 2 is provided with a groove 3011, when the two clamping seats 3 approach the placement table 2 and are closed, the groove wall of the groove 3011 is matched with the outer circumferential surface of the end cover to abut.
[0042] In the present embodiment, the placement table 2 is a protrusion provided on the base 1, a central part higher than the outer ring inclined surface is provided between the protrusion and the base 1, which provides guidance for the cooling liquid injected into the end cover 5, so that the cooling liquid flows smoothly to the flow guide opening 102 and then flows out of the base 1.
[0043] As can be seen from the above technical solution, the placement table 2 is arranged on the base 1, which facilitates the operator to quickly position the placement position of the end cover. The clamping seat 3 is arranged on both sides of the placement table 2 and slides on the base 1 through the push-pull assembly 4. The clamping seat 3 comprises a bearing block 301, the side of the bearing block 301 close to the placement table 2 is provided with a groove 3011, when the two clamping seats 3 approach the placement table 2 and are closed through the push-pull assembly 4, the groove wall of the groove 3011 is matched with the outer circumferential surface of the end cover 5 to abut, thereby clamping the end cover 5. After clamping the end cover 5, the operator can perform drilling operation. Due to the cooperation of the clamping seat 3 and the placement table 2, the end cover 5 can maintain a stable position during drilling and will not move or deform due to vibration or improper operation. After completing the drilling operation, the operator operates the push-pull assembly 4 to make the clamping seat 3 slide away from the placement table 2 along the base 1, thereby releasing the clamped end cover 5. The end cover drilling fixing clamp provided by the present application pushes the clamping seat 3 through the design of the push-pull assembly 4, so that the clamping seat 3 approaches the placement table 2 and clamps the end cover 5, which ensures that the end cover 5 can maintain stability during drilling, and the structure is simple and easy to operate.
[0044] Specifically, the end cover 5 to be drilled is placed on the placement table 2, ensuring that the end cover 5 is stable and in the correct position. The clamping seat 3 is driven by the push-pull assembly 4 to slide towards the placement table 2 until the groove wall of the recess 3011 of the abutting block 301 abuts the outer circumferential surface of the end cover 5. Continue to adjust the push-pull assembly 4 to make the clamping seat 3 apply sufficient clamping force to the end cover 5, ensuring that the end cover 5 does not shake or deform during drilling. Then, the drilling operation is performed, and after drilling is completed, the clamping seat 3 is driven by the push-pull assembly 4 to slide away from the placement table 2, thereby releasing the end cover. Finally, the operator takes out the drilled end cover 5 for the next operation or inspection.
[0045] For reference Figure 2 In this embodiment, the clamping seat 3 also includes a positioning plate 302 located above the abutting block 301, and at least a portion of the positioning plate 302 is opposite the recess 3011. The portion of the positioning plate 302 opposite the recess 3011 is provided with at least one positioning hole 3021. The positioning plate 302 and the positioning hole 3021 thereon provide additional guiding and positioning functions for the end cover 5. When the clamping seat 3 is close to the placement table 2 and is closed, the positioning hole 3021 is opposite the end cover 5, and the operator can determine the drilling position of the end cover 5 through the positioning hole 3021, reducing drilling errors caused by position deviation. When the clamping seat 3 clamps the end cover 5, the positioning hole 3021 is opposite the pre-drilling position on the end cover 5, and the drill bit drills the end cover through the positioning hole 3021.
[0046] Specifically, it also includes a guide 6, which is a hollow structure, and the guide 6 is provided in the positioning hole 3021. During drilling, the hollow structure of the guide 6 can guide the drill bit to drill along a predetermined path, helping to ensure the accuracy and consistency of the drilling position and improving the drilling precision. The hollow structure of the guide 6 can also serve as a channel for the flow of cooling liquid. The cooling liquid flows into the drilling area through the hollow structure of the guide 6, which can remove heat and reduce temperature, thereby protecting the drill bit and the end cover from heat damage.
[0047] It should be noted that the positioning plate 302 is detachably connected with the abutting block 301 through a plurality of fasteners 7. The detachable connection between the positioning plate 302 and the abutting block 301 makes the clamp more flexible and easy to maintain. When it is necessary to replace the positioning plate 302 or perform other maintenance operations, the positioning plate 302 can be easily detached and reinstalled. Specifically, the positioning plate 302 is connected with the abutting block 301 using fasteners 7 (such as bolts, screws, etc.). Typically, these fasteners 7 will pass through the holes on the positioning plate 302 and be screwed into the threaded holes or nuts in the abutting block 301. Tighten the fasteners 7 to ensure a tight and stable connection between the positioning plate 302 and the abutting block 301. When it is necessary to replace the positioning plate 302 or perform maintenance, use a tool (such as a wrench, screwdriver, etc.) to loosen the fasteners and remove the positioning plate 302 from the abutting block 301 for replacement or maintenance. After the replacement or maintenance is completed, reinstall the new positioning plate 302 or the repaired positioning plate 302 on the abutting block 301 according to the above connection process.
[0048] Please refer to Figure 2 and Figure 4 , a clamping block 303 is provided between the positioning plate 302 and the abutting block 301, and the clamping block 303 cooperates with the abutting block 301 to form a V-shaped groove 3012, at least part of the end cover 5 extends into the V-shaped groove 3012. The design of the V-shaped groove 3012 enables the clamping block 303 and the abutting block 301 to jointly clamp the end cover 5, providing stronger clamping force. This helps to prevent the end cover 5 from shaking or deforming during drilling, improving the accuracy and stability of drilling. Specifically, place the end cover 5 on the placement table 2, and drive the clamping seat 3 to slide towards the placement table 2 by the push-pull assembly 4 until the abutting block 301 clamps the end cover 5. At this time, the two side walls of the V-shaped groove 3012 cooperate with the outer circumferential surface of the end cover to provide stable clamping force.
[0049] Further, please refer to Figure 2 , the positioning plate 302 is provided with a plurality of first flow guide grooves 3022, which are uniformly arranged on the side surface of the positioning plate 302 away from the clamping block 303. During drilling, a large amount of heat will be generated between the drill bit and the end cover 5. In order to maintain the normal operation of the drill bit and prolong its service life, it is usually necessary to use cooling liquid for cooling. When using cooling liquid, a part of it will inevitably remain on the positioning plate 302, and the first flow guide grooves 3022 can guide the remaining cooling liquid to flow out of the positioning plate 302. At the same time, during drilling, the drill bit contacts the end cover 5 and generates cutting chips. If these cutting chips are not promptly discharged, they may accumulate inside the clamp, resulting in a decrease in drilling accuracy or damage to the drill bit. The design of the first flow guide grooves 3022 enables the cutting chips to be smoothly discharged from the clamp along the first flow guide grooves 3022, avoiding the problem of cutting chip accumulation.
[0050] Further, please refer toFigures 2 to 5 The base 1 is provided with a sliding groove 101, and the clamping block 301 is provided with a sliding block 304 on the side facing the base 1, and the sliding block 304 extends into the sliding groove 101. The close cooperation between the sliding groove 101 and the sliding block 304 ensures the stable sliding of the clamping block 301 on the base 1, so that the clamping block 301 can accurately clamp the end cover 5, avoiding the drilling error caused by the shaking or deviation of the end cover. Specifically, the operator drives the push-pull rod 401 to extend or retract by operating the hand-held part 401 of the push-pull assembly, thereby driving the clamping block 301 to slide along the sliding groove 101.
[0051] In this embodiment, the base 1 is provided with a plurality of flow guide openings 102 near the placement table 2, and one of the flow guide openings 102 is in communication with a second flow guide groove 103 provided in the sliding groove 101. The communication design of the second flow guide groove 103 and the flow guide opening 102 enables the cooling liquid to flow out of the clamp more smoothly, avoiding the problem of reduced drilling efficiency caused by the accumulation of cooling liquid. This design also makes it more convenient to clean and maintain the clamp. The operator can easily clean the chips and residues in the second flow guide groove 103 and the flow guide opening 102, keeping the clamp clean and tidy.
[0052] It should be noted that the second flow guide groove 103 is inclined along the length direction of the base 1. The inclined second flow guide groove 103 can ensure that the chips and cooling liquid flow out of the base 1 more smoothly, avoiding the problems of accumulation and blockage. Since the chips and cooling liquid can flow out of the clamp more smoothly, the damage and cleaning cost of the clamp caused by the accumulation of chips and cooling liquid is reduced. This helps to reduce maintenance cost and improve the service life of the clamp.
[0053] Please refer to Figure 1 The push-pull assembly 4 includes a push-pull rod 401 and a hand-held part 402, one end of the push-pull rod 401 is connected with the clamping seat 3, the other end is connected with the hand-held part 402, and the push-pull rod 401 cooperates with the hand-held part 402 to drive the clamping seat 3 to approach or move away from the placement table 2. When it is necessary to clamp the end cover 5, the operator holds the hand-held part 402 and pushes forward, causing the push-pull rod 401 to elongate. The elongation of the push-pull rod 401 will drive the clamping seat 3 to approach the placement table 2, until the clamping mechanism on the clamping seat 3 firmly clamps the end cover 5 on the placement table 2. When it is necessary to release the end cover 5, the operator holds the hand-held part 402 and pulls backward, causing the push-pull rod 401 to shorten. The shortening of the push-pull rod 401 will drive the clamping seat 3 to move away from the placement table 2, thereby releasing the clamped end cover 5.
