Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically an adaptive clamping tooling for irregularly shaped automotive parts. Background Technology

[0002] Automotive irregular parts refer to automotive components with complex, irregular, and non-standard geometric shapes. These are typically difficult to manufacture efficiently using traditional machining methods such as turning, milling, and planing, and often require processes like casting, forging, stamping, injection molding, or advanced additive manufacturing (3D printing) to form. These parts are crucial for achieving specific functions, optimizing spatial layout, improving structural strength, meeting aerodynamic requirements, or achieving lightweight goals. Common examples include complex engine mounts, uniquely shaped exhaust manifolds, ergonomic interior trim, streamlined exterior panels, and multifunctional brackets and housings.

[0003] Application number CN202321452800.8 relates to a rotary clamping fixture for automotive parts. Its technical solution includes a housing, an adaptive mechanism, and a cleaning mechanism. This utility model allows the operator to manually rotate a rotating disc, which in turn moves a screw sleeve horizontally. The horizontally moving screw sleeve, via a moving base, pushes a part placed on top of the housing towards the adaptive mechanism. The part experiences pressure through a contact head, which is transmitted to a return spring via a support rod. The high compressibility of the return spring causes the support rod to retract to the fixed base. Multiple sets of support rods working in conjunction with the return spring facilitate the formation of corresponding clamping shapes for irregularly shaped automotive parts, thus achieving the function of clamping irregularly shaped automotive parts.

[0004] In practical applications, the lack of a lubrication structure between the screw and the sleeve results in dry friction on the metal surfaces when they mate. Dry friction can easily damage the surfaces of the screw and sleeve, significantly shortening their service life. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] An adaptive clamping fixture for irregularly shaped automotive parts includes a clamping mechanism and a lubrication mechanism. The clamping mechanism includes a base, two supports slidably mounted inside the base, a flexible clamp detachably mounted on the top of the supports, a threaded rod rotatably passing through one end of the base and connected between the two supports, and a motor connected to one end of the threaded rod. The lubrication mechanism includes a hollow box movably sleeved on the outer end of the threaded rod, a curved tube connected to the top of the hollow box, a T-shaped empty box sleeved on the outer end of the curved tube, a partition installed inside the T-shaped empty box, two air pipes passing through the top of the T-shaped empty box and one side of the partition, respectively, a one-way valve installed on the air pipes, a piston plate slidably mounted inside the T-shaped empty box, a push-pull rod connected between a flexible clamp and the piston plate, and multiple through holes opened on the threaded rod, one of which is located inside the hollow box.

[0008] By adopting the above technical solution, when the two flexible clamps clamp the irregularly shaped parts, the push-pull rod drives the piston plate to move. The piston plate compresses the gas on the right side of the partition, forcing the gas to be discharged through the gas pipe on the partition. At the same time, the movement of the piston plate pushes the lubricating oil on the left side of the partition, causing it to enter the hollow box through the curved pipe. The lubricating oil then flows into the threaded rod and finally seeps out from the through hole, entering the gap between the threaded rod and the support. This process transforms the original dry friction into wet friction, effectively reducing the probability of damage to both parts and thus ensuring their service life.

[0009] In a preferred embodiment, the present invention can be further configured such that the support member is composed of a slider, bolts, a thin plate and crossbars, and the slider has side grooves on both the front and rear sides.

[0010] In a preferred embodiment, the present invention can be further configured such that: four bolts are provided and arranged in a matrix, and the bolts penetrate the top of the slider.

[0011] In a preferred embodiment, the present invention can be further configured as follows: two thin plates are provided, which are respectively fixed to the front and rear sides of the slider; multiple horizontal bars are provided, which are respectively fixed to the top and bottom of the two thin plates; and the thin plates are slidably connected to the base through the horizontal bars.

[0012] In a preferred embodiment, the present invention can be further configured such that the external thread of the threaded rod is set in two segments with opposite directions of rotation.

[0013] In a preferred embodiment, the present invention can be further configured such that: a sleeve is movably sleeved on the outer side of the threaded rod, the sleeve is fixedly connected to one end of the base, and the hollow box is disposed inside the sleeve.

[0014] In a preferred embodiment, this utility model can be further configured such that: multiple corner brackets are connected between the T-shaped empty box and the box sleeve, and the multiple corner brackets are equally spaced and arranged in a row.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] In this invention, when the two flexible clamps clamp the irregularly shaped parts, the push-pull rod drives the piston plate to move. The piston plate compresses the gas on the right side of the partition, forcing the gas to be discharged through the gas pipe on the partition. At the same time, the movement of the piston plate pushes the lubricating oil on the left side of the partition, causing it to enter the hollow box through the curved pipe. The lubricating oil then flows into the threaded rod and finally seeps out from the through hole, entering the gap between the threaded rod and the support. This process transforms the original dry friction into wet friction, effectively reducing the probability of damage to both parts and thus ensuring their service life. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an adaptive clamping fixture for irregularly shaped automotive parts.

[0030] Example 1:

[0031] Combination Figure 1-6 As shown, the present invention provides an adaptive clamping fixture for irregularly shaped automotive parts, including a clamping mechanism 100 and a lubrication mechanism 200. The clamping mechanism 100 includes a base 110, two support members 120 slidably installed inside the base 110, a flexible clamp 130 detachably installed on the top of the support member 120, a threaded rod 140 rotatably passing through one end of the base 110 and connected between the two support members 120, and a motor 150 connected to one end of the threaded rod 140.

[0032] The lubrication mechanism 200 includes a hollow box 210 movably sleeved on the outer end of the threaded rod 140, a curved tube 220 connected to the top of the hollow box 210, a T-shaped empty box 230 sleeved on the outer end of the curved tube 220, a partition 240 installed inside the T-shaped empty box 230, two air pipes 250 passing through the top of the T-shaped empty box 230 and one side of the partition 240 respectively, a one-way valve 260 installed on the air pipes 250, a piston plate 270 slidably installed inside the T-shaped empty box 230, a push-pull rod 280 connected between a flexible clamp 130 and the piston plate 270, and multiple through holes 290 opened on the threaded rod 140, one of which is located inside the hollow box 210.

[0033] Furthermore, the support member 120 is composed of a slider 121, a bolt 123, a thin plate 124 and a crossbar 125. The slider 121 has side grooves 122 on both the front and rear sides. The structural design of the support member 120 ensures that it will not deviate when it moves along the base 110.

[0034] Furthermore, four bolts 123 are provided and arranged in a matrix. The bolts 123 penetrate the top of the slider 121. The number of bolts 123 can improve the connection between the flexible clamp 130 and the support member 120.

[0035] Furthermore, two thin plates 124 are provided, and the two thin plates 124 are respectively fixed to the front and rear sides of the slider 121. Multiple horizontal bars 125 are provided, and the multiple horizontal bars 125 are respectively fixed to the top and bottom of the two thin plates 124. The thin plates 124 are slidably connected to the base 110 through the horizontal bars 125. The thin plates 124 and the horizontal bars 125 cooperate to guide the slider 121 together, making the movement of the slider 121 more stable.

[0036] Furthermore, the external thread of the threaded rod 140 is set in two segments with opposite directions of rotation. The structural design of the threaded rod 140 ensures that the two flexible clamps 130 can approach each other, providing conditions for clamping irregularly shaped parts.

[0037] Example 2:

[0038] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, a sleeve 300 is movably sleeved on the outer side of the threaded rod 140. The sleeve 300 is fixedly connected to one end of the base 110. The hollow box 210 is located inside the sleeve 300. The sleeve 300 can position the hollow box 210 and ensure that the lubricating oil in the hollow box 210 can be smoothly injected into the threaded rod 140.

[0039] Example 3:

[0040] Combination Figure 1 and Figure 4 As shown, in the above embodiment, multiple corner brackets connect the T-shaped empty box 230 and the box sleeve 300. The multiple corner brackets are evenly spaced and arranged in a row. Setting corner brackets can improve the connection between the T-shaped empty box 230 and the box sleeve 300.

[0041] The working principle and usage process of this utility model are as follows: In the initial state, the T-shaped empty box 230 is filled with lubricating oil, and the lubricating oil is located on the left side of the partition 240. At this time, the air pipe 250 at the top of the T-shaped empty box 230 can only exhaust air, while the air pipe 250 on the partition 240 can only intake air. When the device is put into actual use, the motor 150 drives the threaded rod 140 to move, causing the two flexible clamps 130 to move closer to each other to clamp the irregular parts. During this process, the push-pull rod 280 drives the piston plate 270 to move, and as the piston plate 270 moves towards the lubricating oil... As the piston moves closer, it compresses the gas on the right side of the partition 240, forcing the gas to be discharged through the gas pipe 250 on the partition 240. At the same time, the movement of the piston plate 270 pushes the lubricating oil on the left side of the partition 240, causing it to enter the hollow box 210 through the curved pipe 220. The lubricating oil then flows into the threaded rod 140 and finally seeps out from the through hole 290, entering the gap between the threaded rod 140 and the support member 120. This process transforms the original dry friction into wet friction, effectively reducing the probability of damage to both and thus ensuring their service life.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
