Description
Technical Field
[0001] This utility model relates to the field of parts processing technology, and in particular to modular mechanical parts processing fixtures. Background Technology
[0002] Modular machining fixtures are process equipment based on the modular design concept, composed of multiple standardized modules with specific functions. They are used to position, clamp, guide, or support workpieces during the machining process. By flexibly combining different modules, they can quickly adapt to the machining needs of various parts, improve machining efficiency and accuracy, and reduce production costs.
[0003] For parts with complex structures and irregular shapes, standardized modules cannot perfectly fit the workpiece contour, requiring the design of non-standard modules or auxiliary support structures, which reduces the flexibility of modularization. Existing technologies use pneumatic or hydraulically driven multi-degree-of-freedom positioning pins and elastic support blocks, and use sensors to detect the workpiece contour in real time and automatically adjust the positioning point position. However, in actual use, when the multi-degree-of-freedom positioning pins and elastic support blocks need maintenance, too many parts need to be removed, resulting in reduced disassembly efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a modular mechanical parts processing fixture, which aims to improve the problem in the prior art that when multi-degree-of-freedom positioning pins and elastic support blocks need maintenance, too many parts need to be removed, resulting in reduced disassembly efficiency.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a modular mechanical parts processing fixture, including a processing table, a groove on the top of the processing table, a slide rail fixedly connected to the bottom inner side of the groove, a fixing block fixedly connected to the top of the slide rail, telescopic rods fixedly connected to the left and right sides of the fixing block, sliders fixedly connected to the output ends of the two telescopic rods, the bottoms of the two sliders slidably connected to the top of the slide rail, fixing plates fixedly connected to the tops of the two sliders, connecting rods fixedly connected between adjacent fixing plates, clamps fixedly connected between adjacent connecting rods, mounting plates fixedly connected between adjacent clamps, multiple bolts penetrating between adjacent mounting plates, the ends of the multiple bolts penetrating the mounting plate and the clamps, rubber pads fixedly connected between adjacent mounting plates, and a mounting mechanism provided on the top of the fixing block.
[0006] As a further description of the above technical solution:
[0007] The installation mechanism includes a shelf, with locking blocks penetrating the top front and rear sides of the shelf. The top front and rear sides of the processing table are provided with locking grooves, and the front and rear sides of the processing table are provided with insertion grooves. Fixing strips are slidably connected inside the two insertion grooves, and two bolts are threadedly connected to the opposite sides of the two fixing strips.
[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:
[0011] An operating table is fixedly connected to the top of the support plate, and multiple buttons are fixedly connected to the top of the operating table.
[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, when the clamp approaches the object, the inner mounting plate moves with the clamp until the rubber pad contacts the surface of the object. Its elastic deformation conforms to the outline of the object and generates a uniform clamping force, realizing adaptive fixing of objects of different shapes. When replacing the worn rubber pad, there is no need to disassemble the entire clamp. Simply loosen the bolts and remove the mounting plate for quick replacement, thereby improving work efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a modular mechanical parts processing fixture, including a processing table 1. A groove 3 is formed on the top of the processing table 1. A slide rail 4 is fixedly connected to the bottom inner side of the groove 3, providing a sliding track. A fixing block 5 is fixedly connected to the top of the slide rail 4. Telescopic rods 6 are fixedly connected to the left and right sides of the fixing block 5. Slider 7 is fixedly connected to the output ends of both telescopic rods 6. The telescopic rods 6 push the sliders 7 to slide left and right on the slide rail 4. The bottoms of both sliders 7 are slidably connected to the top of the slide rail 4. A fixing plate 8 is fixedly connected to the top of both sliders 7. Connecting rods 9 are fixedly connected between adjacent fixing plates 8. Clamps 10 are fixedly connected between adjacent connecting rods 9. The sliders 7 drive the fixing plates 8 to move. The clamp 10 can also move to clamp objects. Mounting plates 11 are fixedly connected between adjacent clamps 10. Multiple bolts 12 pass through adjacent mounting plates 11. The ends of the bolts 12 pass through the mounting plates 11 and the clamps 10. The mounting plates 11 are fixed between adjacent clamps 10 by bolts 12, which facilitates the installation and removal of mounting plates 11. Rubber pads 13 are fixedly connected between adjacent mounting plates 11. When the clamps 10 clamp inward, the rubber pads 13 can conform to the clamped objects, thus adapting to objects of different shapes. When the rubber pads 13 lose their elasticity, the rubber pads 13 can be quickly replaced by removing the mounting plates 11. The top of the fixing block 5 is provided with a mounting mechanism 2.
[0032] Specifically, the top of the processing table 1 has a groove 3, and the slide rail 4 fixedly connected to the bottom of the inner side of the groove 3 provides a stable sliding track for the overall structure. The fixed block 5 at the top of the slide rail 4 serves as a support base. When the telescopic rods 6 symmetrically installed on its left and right sides are activated, the output end can accurately push the slider 7 to slide left and right along the slide rail 4. The fit design between the bottom of the slider 7 and the top surface of the slide rail 4 ensures low friction and high stability during the translation process. The fixed plate 8 connected to the top of the two sliders 7 forms a horizontal bearing platform. The adjacent sides are rigidly connected by the connecting rod 9, so that the two sides of the structure maintain synchronicity when moving. When the slider 7 is driven to move by the telescopic rod 6, the fixed plate 8 drives the clamp 10 to move closer or further away synchronously through the connecting rod 9, thereby clamping or releasing the object placed between the two. The mounting plate 11 is detachably connected to the inner side by bolts 12. Multiple bolts 12 pass through the pre-set screw holes of the mounting plate 11 and the clamp 10 in sequence, forming a reliable mechanical connection. This allows the mounting plate 11 to be disassembled and assembled in a short time, greatly improving maintenance efficiency. A rubber pad 13 is fixedly connected to the side of the mounting plate 11 facing the object. Its flexible material properties can adaptively conform to the surface of objects of different shapes during clamping. This can avoid damage to the object surface caused by rigid contact and fill the gaps of irregular contours through deformation, significantly improving clamping adaptability. When the rubber pad 13 loses elasticity due to long-term use, simply loosen the bolts 12 and remove the mounting plate 11 to quickly replace the rubber pad 13 without disassembling the entire clamp 10 structure, greatly shortening downtime for maintenance.
[0033] Reference Figure 2 and Figure 5 The installation mechanism 2 includes a shelf 201. A locking block 202 passes through the top and front sides of the shelf 201. A slot 203 is provided on the top and front sides of the processing table 1. The locking block 202 passes through the shelf 201 and inserts into the slot 203. An insertion slot 204 is provided on the front and back sides of the processing table 1. A fixing strip 205 is slidably connected inside each insertion slot 204. The fixing strip 205 is inserted into the insertion slot 204 and passes through the locking block 202 for fixation. Two bolts 206 are threaded onto the opposite sides of the two fixing strips 205. The fixing strips 205 are installed on the front and back sides of the processing table 1 via the bolts 206, facilitating the installation of the shelf 201 and the placement of objects.
[0034] Specifically, the top front and rear sides of the shelf 201 are respectively provided with locking blocks 202, and the top front and rear sides of the processing table 1 are provided with locking grooves 203. During installation, the locking blocks 202 penetrate vertically through the shelf 201 and are inserted into the locking grooves 203 to form a preliminary positioning structure. For further fixation, the front and rear sides of the processing table 1 are also provided with insertion grooves 204, and fixing strips 205 are slidably connected inside. When the fixing strips 205 are pushed in along the insertion grooves 204, their ends will penetrate the pre-set through holes of the locking blocks 202, thus fixing the shelf 201. The locking block 202 is locked to the processing table 1. The outer ends of the fixing strip 205 are provided with threaded holes. The bolts 206 are tightened and fixed to the threaded holes on the side of the processing table 1, forming a double locking mechanism. This enables the quick installation and removal of the shelf 201. When it is necessary to replace or adjust the position of the shelf 201, simply unscrew the bolts 206 and pull out the fixing strip 205 to remove the locking block 202 from the slot 203. This provides flexible workstation reconfiguration capabilities and improves the responsiveness of the production line.
[0035] Reference Figure 1 and Figure 3 A support plate 14 is fixedly connected to the upper front side of the processing table 1. Two diagonal braces 15 are fixedly connected to the bottom of the support plate 14 to support the operating table 16. The operating table 16 is fixedly connected to the top of the support plate 14. Multiple buttons 17 are fixedly connected to the top of the operating table 16 for controlling the device. Support columns 18 are fixedly connected to the four corners of the bottom of the processing table 1. Anti-slip sleeves 19 are fixedly connected to the bottom of the multiple support columns 18 to prevent the device from moving.
[0036] Specifically, a support plate 14 is fixedly connected to the upper front side of the processing table 1. Its bottom is supported by two diagonal braces 15, forming a triangular support structure with the processing table 1, which enhances the load-bearing stability of the operating table 16. The operating table 16 on the top of the support plate 14 integrates multiple control buttons 17 for centralized control of the device's operating parameters. Support columns 18 are fixed at the four corners of the bottom of the processing table 1, and anti-slip sleeves 19 are fitted at the bottom to effectively suppress the device from sliding on the ground.
[0037] Reference Figure 1 and Figure 4 The top of each of the two fixed plates 8 is fixedly connected to a lamp holder 20, and the top of each of the two lamp holders 20 is rotatably connected to a lighting lamp 21 to increase the brightness of the working area. The outer walls of multiple bolts 12 are all perforated with washers 22, and the outer walls of multiple washers 22 are all designed with rounded edges to prevent the bolts 12 from being tightened. The bottoms of the two sliders 7 are equidistantly slidably connected to the top left and right sides of the slide rail 4. The opposite sides of the two connecting rods 9 are equidistantly fixedly connected between the adjacent two fixed plates 8.
[0038] Specifically, the lamp holders 20 are symmetrically arranged on the top of the two fixed plates 8, and their tops are connected to the lighting lamps 21 through a pivot to meet the lighting needs of different work positions and effectively improve the visibility of the work area. The bolts 12 are fixed with washers 22 on the outside to prevent sharp edges from scratching the operators or damaging the surface of the mounting plate 11, and to prevent the bolts from being tightened too much and causing the threads to strip. The two sliders 7 slide at equal distances on the top of the slide rail 4 to ensure that the translation process is smooth and stable. The connecting rods 9 are fixedly connected at equal distances between the adjacent two fixed plates 8.
[0039] Working principle: When the control system triggers the telescopic rod 6, its output end generates a horizontal thrust, pushing the left and right sliders 7 to slide inward or outward along the slide rail 4. The high-precision fit between the slide rail 4 and the bottom surface of the slider 7 ensures the straightness of the translation trajectory. The fixed block 5 serves as the support base of the telescopic rod 6 and is fixed to the processing table 1 by bolts, stably transmitting the driving force to the slider 7. The fixed plate 8 on the top of the slider 7 moves synchronously with it, driving the two clamps 10 to move towards or away from each other through the connecting rod 9. The rigid structure of the connecting rod 9 ensures the synchronous movement of the two clamps 10, avoiding the tilting of the object due to uneven force. When the clamps 10 approach When the object is being handled, the inner mounting plate 11 moves synchronously with the clamp 10 until the rubber pad 13 contacts the object surface. The elastic deformation capability of the rubber pad 13 makes it conform to the outline of the object, while generating a uniform clamping force, thus achieving adaptive fixation for objects of different shapes. When the worn rubber pad 13 needs to be replaced, there is no need to disassemble the entire clamp 10. Simply loosen the bolt 12 and remove the mounting plate 11 to quickly replace the rubber pad 13, ensuring easy disassembly. After maintenance, reinstall the mounting plate 11 and tighten the bolt 12. The telescopic rod 6 then drives the clamp 10 to reset, balancing processing efficiency and ease of equipment maintenance.
[0040] Furthermore, when installing the shelf 201, align the locking blocks 202 on its top front and rear sides with the slots 203 on the top of the processing table 1, and press the shelf 201 vertically downwards to fully insert the locking blocks 202 into the slots 203, ensuring that the shelf 201 is initially positioned horizontally while restricting its vertical displacement. After the initial positioning is completed, push the fixing strip 205 to slide inwards along the insertion slots 204 on the front and rear sides of the processing table 1. The fixing strip 205 inserts into the through hole of the locking block 202, forming a guide and achieving horizontal locking. The outer side of the fixing strip 205 is connected to the screw hole on the side of the processing table 1 through the bolt 206, forming a secondary vertical lock. When it is necessary to adjust the position of the shelf 201 or replace parts, first loosen the bolt 206 to disengage it from the processing table 1; then pull the fixing strip 205 outwards to release the horizontal locking state; finally, lift the shelf 201 upwards and pull the locking blocks 202 out of the slots 203 to complete the disassembly.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
