Description

Technical Field

[0001] This utility model relates to the field of parts clamping tools, and more specifically, to a special-shaped parts clamping platform. Background Technology

[0002] In the fields of aerospace, precision instruments, and high-end equipment manufacturing, special irregular-shaped parts (such as the product in this application with curved thick surface, mounting shaft and mounting shaft hole at both ends, and positioning groove and positioning pin hole on the plate surface) are widely used. Due to their special structure, these parts have much higher requirements for clamping accuracy, stability and adaptability than conventional parts.

[0003] Existing part clamping tools for this type of irregularly shaped special parts mostly use general-purpose fixtures to fix the shaft end of the part, without designing an adaptation scheme for the irregular structure of "one end is a mounting shaft and the other end is a mounting shaft hole". If the mounting shaft and mounting shaft hole are directly fixed, the mounting shaft hole end is prone to gaps due to poor fit between the hole diameter and the fixture, causing the part to swing circumferentially during the locking process; even if it is barely fixed, it is impossible to avoid the part being tilted after clamping, making it difficult to guarantee the vertical positioning requirements of the product plate, and subsequent processing (such as drilling, grinding, assembly) is prone to dimensional deviations.

[0004] Furthermore, when clamping irregularly shaped special parts, manual placement makes it difficult to ensure that the lateral position (along the shaft hole axis) of the part is completely consistent each time, resulting in fluctuations in the lateral position of the positioning groove and positioning pin hole on the part's plate surface. Moreover, the positioning structure of existing clamping tools is mostly a fixed design, which cannot be adjusted in real time according to the actual placement position of the part. In addition, due to the installation accuracy of the clamping equipment itself (such as the assembly gap between the slide rail and the load-bearing frame, and the assembly error of the hole gap between each bolt and screw hole) and the slight deformation of the part itself, existing clamping tools lack an effective positioning fine-tuning mechanism. Summary of the Invention

[0005] The purpose of this application is to provide a clamping pusher for irregularly shaped special parts, which solves the technical problem of stable clamping and positioning of irregularly shaped special parts and ensures the positioning accuracy during clamping.

[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows: A special-shaped parts clamping platform includes a support frame for clamping special products. The special product includes a product plate with mounting shafts and mounting shaft holes at both ends. A positioning groove and a positioning pin hole are formed on the surface of the product plate, with the direction of the positioning pin hole perpendicular to the side surface of the positioning groove. A retaining shaft is fixedly fitted into the mounting shaft hole at one end of the special product, with a transition fit between the two.

[0013] Preferably, the bearing seat is fixed on the load-bearing frame, and a bearing cover is provided on the top of the bearing seat. The end of the bearing cover located on one side of the shaft hole is hinged to the bearing seat, and a bolt is vertically inserted at the end of the bearing cover located on the other side of the shaft hole. A screw hole is vertically inserted on the bearing seat at the position corresponding to the vertical position of the bolt.

[0014] Preferably, the side of the bearing seat and the bearing cover share a common shaft hole, and the diameter of the shaft hole matches the clearance between the mounting shaft and the retaining shaft.

[0015] Preferably, the lateral displacement structure includes a slide rail.

[0016] Preferably, the slide rail is located on the top of the load-bearing frame, and at least one slider is slidably mounted on the slide rail. A mounting plate is fixed on the slider, and a retaining plate is provided on the mounting plate.

[0017] Preferably, limit blocks are respectively provided at both ends of the slide rail, and the limit blocks are fixed on the load-bearing frame.

[0018] Preferably, the retaining plate is further provided with a fixing slot, which is aligned and matched with the screw hole provided on the mounting plate. A bolt is slidably disposed in the fixing slot, and the sliding direction is consistent with the groove depth direction of the positioning slot.

[0019] Preferably, the positioning fine-tuning structure includes a clamping block.

[0020] Preferably, the lower part of the clamping block is slidably sleeved on the guide rail, and the sliding direction is consistent with the length direction of the guide rail.

[0021] Preferably, the top of the clamping block is provided with a slot, and the bottom surface of the mounting plate is provided with a protrusion, which is located in the slot and does not contact the slot surface.

[0022] Preferably, the clamping block has a transverse through-hole, the direction of which is perpendicular to the length direction of the guide rail. Push block one and push block two are slidably disposed in the through-hole, and a screw is rotatably disposed on the clamping block, with the screw threaded through push block one and push block two respectively.

[0023] Preferably, the channel extends laterally through the slot at the top of the clamping block, and the push block one and push block two are respectively arranged on the lateral sides of the slot.

[0024] Preferably, an angle adjustment structure is further provided between the mounting plate and the retaining plate, the angle adjustment structure including a fixing plate.

[0025] Preferably, one end of the fixing plate is hinged to the surface of the mounting plate, and the fixing plate swings in the direction of the length of the guide rail through the hinge point.

[0026] Preferably, a wedge is slidably disposed on the mounting plate, the sliding direction of the wedge is consistent with the length direction of the guide rail, the wedge is located between the lower surface of the fixed plate and the upper surface of the mounting plate, and the lower surface of the fixed plate slides against the inclined surface of the wedge.

[0027] Preferably, the fixing plate is provided with screw holes, which correspond to and match the fixing slots on the retaining plate.

[0028] Preferably, the end of the wedge block away from the inclined plane abuts against a threaded post, the threaded post being threaded through the mounting base in the same direction as the length of the guide rail, and the mounting base being fixed on the mounting plate.

[0029] The wedge has a vertical clearance groove on its inclined surface, and the position of the clearance groove corresponds vertically to the screw hole of the fixing plate.

[0030] Preferably, locking casters are fixedly installed at the bottom of the load-bearing frame.

[0031] The technical solution of this application has at least the following advantages and beneficial effects: This utility model achieves a ring-locking effect by fixing a retaining shaft inside the mounting shaft hole of a special product (the two are fitted together to avoid relative rotation), so that both ends of the part form regular shaft ends (mounting shaft end + retaining shaft end). Combined with the shaft end fixing structure, it achieves a ring-locking effect on both ends of the part. Furthermore, by matching the insertion of the retaining plate and the positioning groove of the part in the vertical retaining structure, it provides synchronous support for both sides of the product plate. At the same time, the positioning pin hole two on the retaining plate and the positioning pin hole one on the part are positioned by a pin shaft, thereby effectively counteracting the plate surface tilting tendency that may occur during the shaft end fixing process, ensuring that the product plate is always in a vertical state and maintaining clamping accuracy. This utility model uses lateral displacement structures symmetrically arranged on both sides of the shaft end fixing structure to drive the vertical holding structure to slide along the lateral extension direction of the product plate, and can adjust the position of the holding plate in real time according to the actual lateral position of the manually placed parts. This utility model achieves precise fine-tuning without affecting lateral displacement adjustment by setting up a positioning fine-tuning structure. The gap design between the protrusion on the bottom surface of the mounting plate and the slot of the clamping block serves as a fine-tuning space. When the screw is rotated, push block one and push block two slide synchronously along the direction perpendicular to the length of the guide rail, applying a lateral thrust to the protrusion of the mounting plate, which drives the position of the fine-tuning positioning pin hole of the holding plate, thereby compensating for the pin hole misalignment caused by the installation error of the clamping equipment and the deformation of the parts. The pin shaft can be quickly inserted without disassembling or modifying the equipment, improving clamping accuracy and efficiency. This invention features a fixed plate that swings around a hinge point and a rotating threaded column that pushes a wedge block to slide along a guide rail. The wedge block's inclined surface presses against the lower surface of the fixed plate to achieve fine-tuning of the angle. This structure allows it to adapt to different types of irregularly shaped parts with different positioning grooves and positioning pin holes without the need to replace the fixture, improving versatility and reducing the cost of customized fixtures.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] Example 1 Please refer to Figure 1This utility model provides a special-shaped parts clamping platform for precisely clamping and fixing special products 5. It includes a load-bearing frame 1, on which related fixing structures for fixing special products 5 are installed. Locking casters 2 are fixedly installed at the bottom of the load-bearing frame 1. When the special product 5 is fixed on the load-bearing frame 1, the special product 5 can be quickly transported to the designated processing or working position through the casters. The locking casters 2 are set as manually lockable casters, which are convenient for temporary stopping at the designated position after transport.

[0047] For further details, please refer to... Figure 2 In this embodiment, the special product 5 includes a product plate 51, a mounting shaft 52, a mounting shaft hole 53, a positioning groove 54, and a positioning pin hole 55.

[0048] Specifically, the thickness surface of the product plate 51 is curved, and the two ends of the product plate 51 are respectively provided with mounting shaft 52 and mounting shaft hole 53. The plate surface of the product plate 51 is provided with positioning groove 54 and positioning pin hole 55. The channel direction of the positioning pin hole is perpendicular to the side groove surface of the positioning groove 54.

[0049] Furthermore, in order to clamp and fix the mounting shaft 52 and mounting shaft hole 53 of the aforementioned special product 5, please refer to... Figure 3 , Figure 4 , Figure 9 and Figure 11 In this embodiment, a shaft end fixing structure 4 is installed on the load-bearing frame 1.

[0050] Among them, a retaining shaft 3 is fixedly sleeved in the mounting shaft hole 53 at one end of the special product 5. The two are fitted together so that they will not rotate relative to each other, so that both ends of the special product 5 become shaft ends (i.e., the mounting shaft 52 end and the mounting shaft hole 53 end with retaining shaft 3), which facilitates installation and fixation through the shaft end fixing structure 4.

[0051] The load-bearing frame 1 is provided with at least two shaft end fixing structures 4, which are respectively matched and fixed to both ends of the special product 5. The shaft end fixing structure 4 includes a shaft seat 41, a shaft cover 42, and a bolt 43.

[0052] Specifically, the bearing seat 41 is fixed on the load-bearing frame 1, and the top of the bearing seat 41 is provided with a bearing cover 42. Both have a shaft hole through them on their sides. The end of the bearing cover 42 located on the axial side of the shaft hole is hinged to the bearing seat 41, so that the bearing cover 42 can be opened and closed relative to the bearing seat 41, making it easy to put the shaft end of the mounting shaft 52 or the clamping shaft 3 into the shaft hole for matching. The end of the bearing cover 42 located on the other side of the shaft hole is provided with a bolt 43 vertically. The bearing seat 41 has a threaded hole vertically through it at the position corresponding to the bolt 43. When the bearing cover 42 and the bearing seat 41 are in contact, the mounting shaft 52 and the clamping shaft 3 can be locked and fixed by the threaded bolt 43 through the bearing seat 41 and the bearing cover 42, thereby locking and fixing both ends of the special product 5.

[0053] Furthermore, although the shaft end and shaft hole end of the special product 5 are locked and fixed by the shaft end fixing structure 4, the special product 5 can swing circumferentially relative to the shaft hole in the shaft end fixing structure 4 during the threaded locking process. This makes it easy for the special product 5 to remain in an inclined state after the shaft end is fixed, resulting in low clamping accuracy. Therefore, for the above situation, please refer to... Figures 4-7 In this embodiment, a vertical holding structure 6 is also provided on the load-bearing frame 1 to maintain the vertical state of the special product 5 after it is clamped. The vertical holding structure 6 is also provided on the horizontal displacement structure 7 to adjust the horizontal position of the vertical holding structure 6 so that it can always match and align with the positioning groove 54 and positioning pin hole 55 on the special product 5.

[0054] Among them, two lateral displacement structures 7 are symmetrically arranged on both sides of the shaft end fixing structure 4 of the special product 5 mounting shaft 52 and mounting shaft hole 53. Each lateral displacement structure 7 is equipped with a vertical holding structure 6. The two vertical holding structures 6 simultaneously position and fix the two sides of the product plate 51, further improving the vertical holding accuracy.

[0055] The vertical retaining structure 6 includes a retaining plate 61, a fixing slot 62, and a positioning pin hole 63.

[0056] The lateral displacement structure 7 includes a slide rail 71, a slider 72, a mounting plate 73, and a limiting block 74.

[0057] Specifically, the slide rail 71 is threadedly fastened to the top of the load-bearing frame 1. At least one slider 72 is laterally slidably mounted on the slide rail 71. A mounting plate 73 is fixed on the slider 72, and a retaining plate 61 is mounted on the mounting plate 73. This allows the retaining plate 61 to move laterally through the slider 72, thereby enabling the retaining plate 61 to be positioned and matched with the special product 5 that is clamped and fixed each time. This allows one end of the retaining plate 61 to be inserted and matched with the positioning groove 54, providing support for the special product 5. It also allows the positioning pin hole 55 through one end of the retaining plate 61 to be aligned and matched with the positioning pin hole 63 (the two pin holes are aligned together by a pin). The special product 5, positioned by the pin shaft, remains in a vertical state.

[0058] Since the shaft end fixing structure 4 is used to fix the special product 5, but the special product 5 is placed manually each time, the lateral position (i.e., the axial position along the shaft hole) of the special product 5 placed on the shaft end fixing structure 4 is easily inconsistent each time, which makes the lateral position of the positioning groove 54 and the positioning pin hole 55 different. Therefore, a guide rail and a slider 72 are provided to facilitate the real-time adjustment of the lateral position of the retaining plate 61 to match it.

[0059] Limiting blocks 74 are provided at both ends of the slide rail 71. The limiting blocks 74 are fixed on the load-bearing frame 1. On the one hand, they limit the position of the slide rail 71 and maintain the installation accuracy (the slide rail 71 is fastened to the load-bearing frame 1 by threads, which has low accuracy). On the other hand, they restrict the slider 72 from sliding out from both ends of the slide rail 71.

[0060] Since the retaining plate 61 needs to be inserted into the positioning groove 54 of the product plate 51 after lateral displacement adjustment, it must also be able to move towards the depth of the positioning groove 54 to avoid displacement interference. Therefore, the retaining plate 61 is also provided with a fixing slot 62, and the mounting plate 73 is provided with a screw hole that aligns with the fixing slot 62. A bolt is slidably installed in the fixing slot 62, with the sliding direction along the depth of the positioning groove 54. Under normal circumstances, the bolt in the fixing slot 62 is threadedly fixed to the screw hole on the mounting plate 73. When the retaining plate 61 is moved to the alignment and matching position with the positioning groove 54 by the lateral displacement structure 7, the bolt is loosened, allowing the retaining plate 61 to move relative to the mounting plate 73. The retaining plate 61 is then inserted into the positioning groove 54 on the product plate 51 to provide positioning support for the product plate 51. Finally, the bolt is tightened to fix the retaining plate 61 to the mounting plate 73.

[0061] Furthermore, during the actual clamping process of special product 5, positioning errors often occur due to the installation errors of the clamping equipment itself. Therefore, when setting the pin hole and pin shaft positioning, the pin shaft may not be able to be aligned and inserted into the pin hole due to the installation accuracy.

[0062] For the above issues, please refer to... Figures 5-8 In this embodiment, a positioning fine-tuning structure 8 is also provided between the guide rail and the mounting plate 73, which is used to adjust the positioning accuracy of the mounting plate 73 and the retaining plate 61 thereon without affecting the lateral displacement adjustment.

[0063] The positioning fine-tuning structure 8 includes a clamping block 81, a push block one 82, a push block two 83, and a screw 84.

[0064] Specifically, the lower part of the clamping block 81 is slidably sleeved on the guide rail and can slide along the length of the guide rail, making it easy to move together with the mounting plate 73 on the slider 72. The top of the clamping block 81 is provided with a slot, and the bottom surface of the mounting plate 73 is provided with a protrusion. The protrusion is located in the slot but does not contact the slot surface (there is a gap). The clamping block 81 has a transverse through-hole, and the direction of the through-hole is perpendicular to the length direction of the guide rail. Push block 1 82 and push block 2 83 are slidably arranged in the through-hole (both push blocks are engaged with the inside of the through-hole through a slot, thereby restricting its rotation and making it only slide). A screw 84 is rotatably arranged on the clamping block 81. The screw 84 is threaded through push block 1 82 and push block 2 83 respectively. When the screw 84 rotates, it can drive push block 1 82 and push block 2 83 to slide laterally synchronously.

[0065] Preferably, the channel also extends laterally through the slot at the top of the clamping block 81. Push block 1 82 and push block 2 83 are respectively arranged on the lateral sides of the slot. When push block 1 82 and push block 2 83 are displaced by screw 84, they can slide into the slot and abut against the protruding position of the mounting plate 73, thereby applying a lateral thrust to the mounting plate 73.

[0066] Preferably, when fine-tuning the positioning of the second positioning pin hole 63 on the retaining plate 61 and the first positioning pin hole 55 on the product plate 51, first loosen the screws connecting the mounting plate 73 and the slider 72 (both are threaded), then rotate the screw 84, using the screw 84 thread to drive the two push blocks to move in the same direction (located on the same thread), thereby pushing the protrusion in the slot, driving the retaining plate 61 on the mounting plate 73 to make fine-tuning of the displacement, so that the two positioning pin holes are aligned, making it easy to insert the pin for positioning. After the fine-tuning is completed, tighten the screws of the mounting plate 73 and the slider 72.

[0067] Example 2 In actual product manufacturing, the overall shape of the special product 5 (i.e., product plate 51) remains unchanged. However, the surface structure of the product plate 51 is adjusted accordingly to accommodate the assembly equipment. For example, when the special product 5 is assembled onto different equipment, the positions of the positioning grooves 54 and positioning pin holes 55 on the plate surface are changed to accommodate the distribution of various structures within the equipment, thus avoiding interference with other internal structures. Therefore, during the actual clamping process of the special product 5, the distribution of the positioning grooves 54 and positioning pin holes 55 on the plate surface of the special product 5 used to assemble different equipment may be inconsistent. This makes it difficult to adapt the special product 5 for different equipment during the actual clamping process (generally, to facilitate the manufacture of molds for product production, the center points of the positioning grooves 54 and positioning pin holes on the plate surface are not changed; only their position angles are changed to avoid interference with structures on different equipment).

[0068] For the above situation, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 10 In this embodiment, an angle adjustment structure 9 is also provided between the mounting plate 73 and the retaining plate 61 to adjust the angle of the retaining plate 61 and match it with the positioning groove 54 and positioning pin hole 55 on different special products 5.

[0069] The angle adjustment structure 9 includes a fixing plate 91, a wedge block 92, a mounting bracket, a threaded post 94, and a clearance groove 95.

[0070] Specifically, one end of the fixing plate 91 is hinged to the upper surface of the mounting plate 73, allowing the fixing plate 91 to swing along the length of the guide rail. A wedge 92 is also slidably disposed on the mounting plate 73 (the two are slidably engaged through a slot). The sliding direction is along the length of the guide rail. The wedge 92 is located between the lower surface of the fixing plate 91 and the upper surface of the mounting plate 73. When the wedge 92 moves closer to the fixing plate 91, the unhinged end of the fixing plate 91 will slide on the inclined surface of the wedge 92, thereby causing the fixing plate 91 to swing and change the angle of the fixing plate 91.

[0071] In this embodiment, the fixing plate 91 is provided with screw holes, which correspond to and match the fixing slots 62 on the retaining plate 61, so that the retaining plate 61 is fixed on the fixing plate 91 and swings with the fixing plate 91 to realize the angle adjustment, thereby making the retaining plate 61 aligned with the positioning slots 54 at different positions and angles on the product plate 51.

[0072] In order to accurately adjust the swing angle of the fixed plate 91, a threaded post 94 is abutted at the end of the wedge 92 away from the inclined surface. The threaded post 94 is threaded through the mounting base 93, and the threading direction is consistent with the length direction of the guide rail. The mounting base 93 is fixed on the mounting plate 73. When it is necessary to adjust the angle of the retaining plate 61, the threaded post 94 is manually rotated, so that the threaded post 94 moves towards the fixed plate 91 through the mounting base 93, thereby abutting against the inclined surface of the wedge 92 and pressing the lower plate surface of the fixed plate 91, changing the angle of the retaining plate 61 on the fixed plate 91. (When it is necessary to reduce the angle between the fixed plate 91 and the mounting plate 73, it is only necessary to rotate the threaded post 94 away from the fixed plate 91, and then manually push the wedge 92 away from the fixed plate 91.)

[0073] When the bolt located in the fixing slot 62 of the retaining plate 61 is threaded to the screw hole on the fixing plate 91, the bolt will protrude from the fixing plate 91. The lower plate surface of the fixing plate 91 abuts against the inclined surface of the wedge block 92. At this time, the protruding bolt is likely to come into contact with the wedge block 92, thus affecting the angle adjustment. Therefore, a clearance groove 95 is also vertically opened on the inclined surface of the wedge block 92. The position of the clearance groove 95 corresponds vertically to the screw hole of the fixing plate 91, so as to avoid the bolt.

[0074] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
