Description

Technical Field

[0001] This utility model relates to the field of fixture technology for boring machine processing, specifically a fixture for boring casting products. Background Technology

[0002] The boring machine fixture is specifically designed to improve workpiece positioning accuracy and machining stability. The main structure is made of high-strength alloy material, possessing high rigidity and deformation resistance, and can withstand the cutting forces during boring.

[0003] In the field of machining, fixtures are key equipment for ensuring workpiece positioning accuracy and machining stability. Currently, most fixtures use a bolt and washer clamping method, which has significant limitations. On the one hand, the manual tightening of bolts and nuts relies on the operator's experience, making it difficult to ensure uniform clamping force at all points, which can easily lead to workpiece deformation and affect machining accuracy. On the other hand, repeated bolt installation and removal can wear down the threads, shortening the fixture's lifespan, and each clamping and removal requires a significant amount of time, severely restricting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for boring of casting products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixture for boring of casting products, comprising a base plate, a mounting plate fixedly connected to the top of the base plate, a clamping mechanism mounted on the top of the mounting plate, and an adjustment mechanism mounted inside the clamping mechanism; The clamping mechanism includes a mounting base, which is fixedly connected to the top of the mounting plate. A rotating sleeve is fixedly connected to the middle of the outer side of the mounting base. A movable rod is rotatably connected inside the rotating sleeve. A wrench is fixedly connected to one end of the outer side of the movable rod. A height wheel is fixedly connected to one end of the inner side of the movable rod. A fixed seat is fixedly connected to the base of the mounting plate inside the height wheel. A rotating rod is hinged to the middle of the outer side of the fixed seat. An adjustment mechanism is inserted into the middle of the rotating rod.

[0006] Preferably, a stabilizing block is fixedly connected to the inner side of the mounting base, and the stabilizing block has a rotation hole corresponding to the movable rod.

[0007] Preferably, the top inner side of the mounting base has a movable opening, which is configured to correspond to the adjustment mechanism.

[0008] Preferably, the mounting base has an installation opening in the middle of its outer side, and an adjustment mechanism is installed in the installation opening.

[0009] Preferably, the mounting bases are distributed on the top of the mounting plate near the outer ring, and there are three mounting bases arranged in a circle on the top of the mounting plate.

[0010] Preferably, the top thickness of the high and low wheels is greater than the bottom thickness, and the height difference of the stabilizing blocks is smooth.

[0011] Preferably, the adjusting mechanism includes a movable block, which is inserted into the middle of the rotating rod. A threaded sleeve is fixedly connected to the top middle of the movable block. A threaded rod is threadedly connected to the inner thread of the threaded sleeve. A clamping block is threadedly connected to the threaded rod near the top. A stabilizing bar is fixedly connected to the bottom of the clamping block.

[0012] Preferably, an extension block is provided on the top inner side of the clamping block, and the extension block and the clamping block are combined to form a hook shape.

[0013] Preferably, two stabilizing bars are provided, which are distributed on the outer and inner sides of the bottom of the clamping block. The movable block has a sliding groove corresponding to the two stabilizing bars, and the bottom of the stabilizing bar is slidably connected to the sliding groove.

[0014] Preferably, the clamping block and the movable block are provided with threaded holes on the corresponding threaded rods, the stabilizing bar on the inner side of the clamping block is provided with a scale, and the inner side of the movable block is provided with a triangular indicator mark corresponding to the scale.

[0015] Compared with the prior art, this utility model provides a fixture for boring of casting products, which has the following advantages: 1. This fixture for boring castings achieves uniform clamping through a three-position clamping mechanism with a linked design. When the wrench is turned, the movable rod drives the high and low rollers to rotate. Utilizing the thickness difference between the top and bottom of the high and low rollers (the top thickness is greater than the bottom), the rotating rod on the fixed seat swings synchronously. The rotating rod drives the clamping block through the movable block in the adjustment mechanism. The symmetrical structure of the three mounting seats in a circle ensures that the clamping force is applied synchronously on all three sides. For example, when the high and low rollers rotate, their smooth height difference evenly transmits the thrust to the rotating rod, causing the clamping block to hook the edge of the casting with the same force, avoiding the uneven force caused by human error when manually tightening bolts.

[0016] 2. This fixture for boring castings uses a wrench-driven mechanical quick-clamping structure, replacing the repeated disassembly and assembly of traditional bolts. The operator only needs to rotate the wrench 1-2 turns to complete the clamping through the linkage of the high and low pulleys and the rotating rod. The threaded rod and threaded sleeve in the adjustment mechanism, combined with the stabilizing bar and sliding groove guide at the bottom of the clamping block, allow for precise control of the clamping force via scale and triangular indicator marks, preventing thread wear. Furthermore, when changing the casting specifications, simply rotate the threaded rod to adjust the height of the clamping block; the stabilizing bar's limiting effect within the sliding groove prevents the clamping block from shifting, eliminating the need to disassemble the entire mechanism.

[0019] 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.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] This utility model provides the following technical solution: Example

[0022] Please see Figure 1-3 A fixture for boring of casting products includes a base plate 1, a mounting plate 4 fixedly connected to the top of the base plate 1, a clamping mechanism 2 mounted on the top of the mounting plate 4, and an adjustment mechanism 3 mounted inside the clamping mechanism 2. The clamping mechanism 2 includes a mounting base 23, which is fixedly connected to the top of the mounting plate 4. A rotating sleeve 22 is fixedly connected to the middle of the outer side of the mounting base 23. A movable rod 28 is rotatably connected inside the rotating sleeve 22. A wrench 21 is fixedly connected to one end of the outer side of the movable rod 28. A high-low wheel 25 is fixedly connected to one end of the inner side of the movable rod 28. A fixed seat 26 is fixedly connected to the floor of the mounting plate 4 inside the high-low wheel 25. A rotating rod 27 is hinged to the middle of the outer side of the fixed seat 26. An adjustment mechanism 3 is inserted into the middle of the rotating rod 27.

[0023] Uniform clamping is achieved through the linkage design of the three-position clamping mechanism 2. When the wrench 21 is turned, the movable rod 28 drives the high and low rollers 25 to rotate. Utilizing the thickness difference between the top and bottom of the high and low rollers 25 (the top thickness is greater than the bottom), the rotating rod 27 on the fixed seat 26 swings synchronously. The rotating rod 27 drives the clamping block 32 to move through the movable block 34 in the adjusting mechanism 3. The symmetrical structure of the three mounting seats 23 forming a circle ensures that the clamping force on the three sides is applied synchronously. For example, when the high and low rollers 25 rotate, their smooth height difference will uniformly transmit the thrust to the rotating rod 27, causing the clamping block 32 to hook the edge of the casting with the same force, avoiding the uneven force caused by human operation differences when manually tightening bolts in the traditional way.

[0024] A stabilizing block 24 is fixedly connected to the inner side of the mounting base 23, and the stabilizing block 24 has a rotation hole corresponding to the movable rod 28.

[0025] The mounting base 23 has an opening 231 on the top inner side, and the opening 231 is set to correspond to the adjustment mechanism 3.

[0026] An installation port 261 is provided in the middle of the outer side of the fixed base 26, and an adjustment mechanism 3 is installed in the installation port 261.

[0027] Mounting bases 23 are distributed on the top of the mounting plate 4 near the outer ring, and there are three mounting bases 23 arranged in a circle on the top of the mounting plate 4.

[0028] The top thickness of the high and low wheel 25 is greater than the bottom thickness, and the height difference of the stabilizing block 24 is in a smooth state. Example

[0029] Please see Figure 1-5 Furthermore, based on Embodiment 1, the adjustment mechanism 3 further includes a movable block 34, which is inserted into the middle of the rotating rod 27. A threaded sleeve 37 is fixedly connected to the top middle of the movable block 34. A threaded rod 31 is threadedly connected to the inner thread of the threaded sleeve 37. A clamping block 32 is threadedly connected to the top of the threaded rod 31. A stabilizing bar 33 is fixedly connected to the bottom of the clamping block 32.

[0030] The mechanical quick-clamping structure driven by the wrench 21 replaces the repeated disassembly and assembly of traditional bolts. The operator only needs to rotate the wrench 21 1-2 turns to complete the clamping through the linkage of the high-low wheel 25 and the rotating rod 27. The threaded rod 31 and threaded sleeve 37 in the adjusting mechanism 3 cooperate, and with the stabilizing bar 33 at the bottom of the clamping block 32 and the guide of the sliding groove 35, the clamping force can be precisely controlled through the scale 36 and the triangular indicator, avoiding thread wear. Furthermore, when it is necessary to change the casting specifications, only the threaded rod 31 needs to be rotated to adjust the height of the clamping block 32. The limiting effect of the stabilizing bar 33 within the sliding groove 35 prevents the clamping block 32 from shifting, without disassembling the entire mechanism.

[0031] An extension block is provided on the top inner side of the clamping block 32, and the extension block and the clamping block 32 are combined to form a hook shape.

[0032] Two stabilizing bars 33 are provided, which are distributed on the outer and inner sides of the bottom of the clamping block 32. The movable block 34 has a sliding groove 35 corresponding to the two stabilizing bars 33, and the bottom of the stabilizing bar 33 is slidably connected in the sliding groove 35.

[0033] Both the clamping block 32 and the movable block 34 have threaded holes 38 on the threaded rod 31. The stabilizing bar 33 on the inner side of the clamping block 32 has a scale 36, and the inner side of the movable block 34 has a triangular indicator mark corresponding to the scale 36.

[0034] In actual operation, when this device is used, the linkage design of the three-position clamping mechanism 2 achieves uniform clamping. When the wrench 21 is turned, the movable rod 28 drives the high and low rollers 25 to rotate. Utilizing the thickness difference between the top and bottom of the high and low rollers 25 (the top thickness is greater than the bottom), the rotating rod 27 on the fixed seat 26 swings synchronously. The rotating rod 27 drives the clamping block 32 to move through the movable block 34 in the adjusting mechanism 3. The symmetrical structure of the three mounting seats 23 forming a circle ensures that the clamping force on the three sides is applied synchronously. For example, when the high and low rollers 25 rotate, their smooth height difference change will evenly transmit the thrust to the rotating rod 27, causing the clamping block 32 to hook the edge of the casting with the same force, avoiding the uneven force caused by human operation differences when manually tightening bolts in the traditional way.

[0035] The mechanical quick-clamping structure driven by wrench 21 replaces the repeated disassembly and assembly of traditional bolts. The operator only needs to rotate wrench 21 1-2 turns to complete the clamping through the linkage of the high / low wheel 25 and the rotating rod 27. The threaded rod 31 and threaded sleeve 37 in the adjusting mechanism 3 cooperate, and with the stabilizing bar 33 at the bottom of the clamping block 32 and the guide of the sliding groove 35, the clamping force can be precisely controlled through the scale 36 and the triangular indicator, avoiding thread wear. Furthermore, when it is necessary to change the size of the casting, only the height of the clamping block 32 needs to be adjusted by rotating the threaded rod 31. The limiting effect of the stabilizing bar 33 within the sliding groove 35 prevents the clamping block 32 from shifting, without disassembling the entire mechanism.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
