Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a fully automatic fixture for processing connecting rods. Background Technology

[0002] With the continuous improvement of economic level, automobiles have become one of the essential tools for people's travel. For automobiles, the main power comes from their engines. The engine, together with the connecting rod, piston, crankshaft, cylinder and other components, constitutes the engine's connecting rod mechanism. It needs to work well with these components to realize the engine's intake, compression, power and exhaust cycles.

[0003] However, with the significant increase in automobile production and the stringent requirements for product quality, fixtures are often used to assist in production in order to ensure processing accuracy, improve production efficiency, and reduce costs, thereby reducing quality problems in the production process.

[0004] Chinese Utility Model Patent Publication No. CN222405368U discloses a fixture for machining connecting rods. This fixture, by rotating an adjusting component, drives an adjusting screw to rotate. The clamping blocks are restricted from rotating by guide blocks. When the adjusting screw rotates, the clamping blocks move along the direction of the guide groove. Simultaneously, by controlling the two clamping blocks to move closer to each other, the connecting rod can be clamped. Through its unique structural design, multiple machining processes for connecting rods can be completed on a single fixture, effectively improving machining efficiency. However, this fixture is not convenient for fixing multiple connecting rods, which can easily lead to low work efficiency during use. Furthermore, it is not convenient for positioning connecting rod bodies of different sizes, resulting in poor versatility and hindering its widespread use. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a fully automatic fixture for processing connecting rods, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a fully automatic fixture for processing connecting rods, including a base, a connecting rod body placed on the base, and a limiting and fixing plate fixedly installed on one side of the base. The base has a slot on the side near the connecting rod body, and a protrusion is fixedly installed on the side of the base near the slot. A positioning seat with an interference fit is installed on the base through the slot and the protrusion. A positioning block adapted to the connecting rod body is fixedly installed on the other end of the positioning seat away from the protrusion. A limiting seat is provided on the other end of the base away from the fixing plate. The side of the limiting seat that contacts the connecting rod body adopts a "V" shape design.

[0007] Preferably, positioning holes are provided at the four corners of the base away from the connecting rod body. The cross-section of the base is in a "U" shape structure, and a reinforcing frame is fixedly installed at the other end of the base away from the connecting rod body.

[0008] Through the above technical solution, the base can be fixed on the workbench of the processing equipment by using bolts or other connecting parts through the positioning holes, ensuring the stable position of the base during the processing. And when the base is subjected to external forces such as vibration and impact during the processing, through the design of the bottom reinforcing frame, these forces can be effectively dispersed and borne, reducing the deformation of the base.

[0009] Preferably, a cylinder is fixedly installed at the other end of the fixing plate away from the base. A through groove is provided at the center line of the fixing plate. The output shaft of the cylinder penetrates through the through groove and extends to the other end of the fixing plate. A fixing block is fixedly installed on the output shaft of the cylinder, and a sliding plate is fixedly installed at the other end of the fixing block away from the cylinder.

[0010] Through the above technical solution, during use, start the cylinder, and the output shaft of the cylinder will perform a linear reciprocating motion along the through groove. When the output shaft of the cylinder extends, it will drive the fixing block and the connected sliding plate to move towards the direction close to the connecting rod body. When the connecting rod contacts the positioning block on the base, its automatic fixing can be realized.

[0011] Preferably, a slide rail is fixedly installed on the base and located at the center line. A slider slidably connected to the slide rail is fixedly installed at one end of the sliding plate close to the base. A limiting block with the same structure as the limiting seat is fixedly installed at the other end of the sliding plate away from the fixing plate. A positioning bolt two is threadedly connected to one side of the fixing block close to the cylinder and penetrates through the fixing block and extends into the interior of the sliding plate.

[0012] Through the above technical solution, due to the limiting block having the same structure as the limiting seat, when the sliding plate moves, the limiting block can cooperate with the limiting seat to limit and clamp the connecting rod body from the front and rear ends, adapting to the positioning of connecting rod bodies of different sizes. And by adjusting the position of the sliding plate and using the cooperation between the limiting block and the limiting seat, the positioning and clamping of the connecting rod body can be realized, avoiding the displacement of the connecting rod body during the processing.

[0013] Preferably, there are two identical sets of the convex blocks, positioning blocks, limiting seats and limiting blocks. Each set of the convex blocks, positioning blocks, limiting seats and limiting blocks has two identical ones. The two sets of the convex blocks, positioning blocks, limiting seats and limiting blocks are symmetrically distributed about the center line of the base.

[0014] Through the above technical solution, through the design of the two sets of the convex blocks, positioning blocks, limiting seats and limiting blocks, multiple connecting rod bodies can be fixed, improving the processing efficiency. When performing processing operations such as drilling and milling, the practicability of the overall fixture can be improved.

[0015] Preferably, the other end of the limiting seat away from the base is threadedly connected to a positioning bolt that passes through the limiting seat and extends into the interior of the base, and one limiting seat is provided with two identical positioning bolts.

[0016] With the above technical solution, when installing the limit seat, after placing the limit seat on the corresponding position on the base, the first positioning bolt is rotated to gradually screw it into the base, thereby firmly fixing the limit seat on the base. Setting two positioning bolts can further enhance the stability of the connection between the limit seat and the base, and prevent the limit seat from shifting during the processing.

[0017] Preferably, the protrusion and the positioning seat are adapted to each other, the positioning block and the positioning seat correspond one-to-one, and the base has multiple reserved slots distributed at equal intervals on the side away from the positioning hole.

[0018] The above technical solution utilizes the design of protrusions and positioning seats to achieve rapid positioning and installation. Subsequently, the positioning block corresponds to the groove of the connecting rod body, which can play a pre-positioning role. Then, with the help of a cylinder, secondary fixing can be achieved. Furthermore, when processing connecting rod bodies with special shapes or special processing requirements, corresponding auxiliary components can be installed in the reserved slots as needed to provide additional support for the connecting rod body, thereby improving the versatility and adaptability of the fixture.

[0020] 1. This fully automatic fixture for machining connecting rods, through the design of two sets of protrusions, positioning blocks, limiting seats and limiting blocks, can fix multiple connecting rod bodies, which can improve its machining efficiency.

Furthermore, by adjusting the position of the slide, the positioning and clamping of the connecting rod bodies can be achieved by utilizing the cooperation of the limiting blocks and limiting seats.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides a fully automatic fixture for processing connecting rods, including a base 1, a connecting rod body 18 placed on the base 1, and a limiting and fixing plate 10 fixedly installed on one side of the base 1. A slot 3 is provided on the side of the base 1 near the connecting rod body 18, and a protrusion 4 is fixedly installed on the side of the base 1 near the slot 3. A positioning seat 5 with an interference fit is installed on the base 1 through the slot 3 and the protrusion 4.

A limiting seat 8 is provided on the other end of the base 1 away from the fixing plate 10. The side of the limiting seat 8 that contacts the connecting rod body 18 adopts a "V" shape design.

[0031] Specifically, positioning holes 2 are provided at the four corners of the base 1 away from the connecting rod body 18. The cross-section of the base 1 is in a "U" shape. A reinforcing frame 19 is fixedly installed at the other end of the base 1 away from the connecting rod body 18. The advantage is that the base 1 can be fixed to the workbench of the processing equipment through the positioning holes 2 using connecting parts such as bolts, ensuring the stable position of the base 1 during the processing. And when external forces such as vibration and impact forces act during the processing, through the design of the bottom reinforcing frame 19, these forces can be effectively dispersed and borne, reducing the deformation of the base 1.

[0032] Specifically, a cylinder 15 is fixedly installed at the other end of the fixing plate 10 away from the base 1. A through groove 11 is provided at the center line of the fixing plate 10. The output shaft of the cylinder 15 penetrates through the through groove 11 and extends to the other end of the fixing plate 10. A fixing block 16 is fixedly installed on the output shaft of the cylinder 15. A sliding plate 12 is fixedly installed at the other end of the fixing block 16 away from the cylinder 15. The advantage is that during use, when the cylinder 15 is started, the output shaft of the cylinder 15 will perform a linear reciprocating motion along the through groove 11. When the output shaft of the cylinder 15 extends, it带动 the fixing block 16 and the connected sliding plate 12 to move in the direction靠近 the connecting rod body 18. When the connecting rod contacts the positioning block 6 on the base 1 and completes, its automatic fixing can be achieved.

[0033] Specifically, a slide rail 7 is fixedly installed on the base 1 and位于 the center line. A slider 13 slidably connected to the slide rail 7 is fixedly installed at one end of the sliding plate 12靠近 the base 1. A limiting block 14 having the same structure as the limiting seat 8 is fixedly installed at the other end of the sliding plate 12 away from the fixing plate 10. A positioning bolt two 17 penetrating through the fixing block 16 and extending into the interior of the sliding plate 12 is threadedly connected to one side of the fixing block 16靠近 the cylinder 15. The advantage is that due to the same structure of the limiting block 14 and the limiting seat 8, when the sliding plate 12 moves, the limiting block 14 can cooperate with the limiting seat 8 to limit and clamp the connecting rod body 18 from the front and rear ends, adapting to the positioning of connecting rod bodies 18 of different sizes. And by adjusting the position of the sliding plate 12 and using the cooperation of the limiting block 14 and the limiting seat 8, the positioning and clamping of the connecting rod body 18 are achieved, avoiding the displacement of the connecting rod body 18 during the processing.

[0034] Embodiment Two: As Figure 2-6 shown, as an improvement over the previous embodiment.

[0035] Specifically, there are two identical sets of bumps 4, positioning blocks 6, limiting seats 8, and limiting blocks 14. Each set of bumps 4, positioning blocks 6, limiting seats 8, and limiting blocks 14 has two identical ones. The two sets of bumps 4, positioning blocks 6, limiting seats 8, and limiting blocks 14 are symmetrically distributed about the center line of the base 1. The advantage is that through the design of the two sets of bumps 4, positioning blocks 6, limiting seats 8, and limiting blocks 14, its processing efficiency can be improved. When performing processing operations such as drilling and milling, the practicality of the overall fixture can be improved.

[0036] Specifically, the other end of the limiting seat 8 away from the base 1 is threaded with a positioning bolt 9 that passes through the limiting seat 8 and extends into the interior of the base 1. One limiting seat 8 is provided with two identical positioning bolts 9. The advantage is that when installing the limiting seat 8, after placing the limiting seat 8 in the corresponding position on the base 1, the positioning bolt 9 is rotated to gradually screw it into the interior of the base 1, thereby firmly fixing the limiting seat 8 to the base 1. Providing two positioning bolts 9 can further enhance the stability of the connection between the limiting seat 8 and the base 1, and prevent the limiting seat 8 from shifting during the processing.

[0037] Specifically, the protrusion 4 and the positioning seat 5 are adapted to each other, and the positioning block 6 corresponds one-to-one with the positioning seat 5. The base 1 has multiple reserved slots 20 distributed at equal intervals on the side away from the positioning hole 2. The advantage is that the design of the protrusion 4 and the positioning seat 5 can realize quick positioning and installation. Then, the positioning block 6 corresponds to the groove of the connecting rod body 18, which can play a pre-positioning role. Then, with the cylinder 15, secondary fixation can be achieved. Furthermore, when processing some special shapes or connecting rod bodies 18 with special processing requirements, corresponding auxiliary components can be installed in the reserved slots 20 as needed to provide additional support for the connecting rod body 18, thereby improving the versatility and adaptability of the fixture.

[0038] Working Principle: When in use, the cylinder 15 is activated, and its output shaft reciprocates linearly along the through groove 11. When the output shaft extends, it drives the fixed block 16 and the connected slide plate 12 to move closer to the connecting rod body 18. After the connecting rod contacts the positioning block 6 on the base 1, it is automatically fixed. The limiting block 14, with the same structure as the limiting seat 8, allows the limiting block 14 to cooperate with the limiting seat 8 when the slide plate 12 moves, limiting and clamping the connecting rod body 18 from both ends. This accommodates the positioning of connecting rod bodies 18 of different sizes. By adjusting the position of the slide plate 12, bolts or other connecting parts can be used through the positioning hole 2 to fix the base 1 to the worktable of the processing equipment, ensuring the stability of the base 1 during processing. Furthermore, when subjected to external forces such as vibration and impact during processing, the bottom reinforcing frame 19 effectively disperses and bears these forces, reducing deformation of the base 1. The cooperation between the limiting block 14 and the limiting seat 8 achieves positioning and clamping of the connecting rod body 18, preventing… During the machining process, the connecting rod body 18 is displaced. The design of two sets of protrusions 4, positioning blocks 6, limit seats 8, and limit blocks 14 can improve its machining efficiency. When performing drilling, milling, and other machining operations, the overall practicality of the fixture can be improved. When installing the limit seat 8, after placing the limit seat 8 in the corresponding position on the base 1, the positioning bolt 9 is rotated to gradually screw it into the base 1, thereby firmly fixing the limit seat 8 on the base 1. The two positioning bolts 9 can further enhance the stability of the connection between the limit seat 8 and the base 1. During the machining process, the limit seat 8 is displaced. The design of protrusions 4 and positioning seats 5 can achieve quick positioning and installation. Then, the positioning block 6 and the groove of the connecting rod body 18 can play a pre-positioning role. Then, with the help of the cylinder 15, secondary fixing can be achieved. Furthermore, when machining some special-shaped connecting rod bodies 18 or those with special machining requirements, corresponding auxiliary components can be installed in the reserved slot 20 as needed to provide additional support for the connecting rod body 18, improving the versatility and adaptability of the fixture.
