Abstract
Description
Technical Field
[0001] This utility model belongs to the field of workpiece clamping technology, specifically a workpiece processing clamping device. Background Technology
[0002] Stamping of automotive parts refers to the process of using equipment such as punch presses to cut, punch, and bend metal sheets or wires according to drawings to manufacture the metal parts required for automobiles. Connecting rods are automotive components used to connect pistons and crankshafts, and to transmit the force on the piston to the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft.
[0003] A patent with publication number CN118513463A discloses an anti-deviation device for stamping automotive parts, relating to the field of automotive parts processing technology. The device includes a base plate with uprights fixedly connected to its top corners. During stamping of automotive parts, the workpiece passes between a drive roller and a driven roller on one side, then through a sliding frame and the inside of a slot. A starter motor drives the drive roller to rotate, and the workpiece is clamped and supported by the sliding frames on both sides. The sliding frames adapt to the width of the workpiece for positioning. The rebound force of a third spring applies downward pressure to a stabilizing plate, thereby clamping and fixing the workpiece from above.
[0004] In current technologies, when boring on a horizontal machining center, the connecting rod workpiece is not well fixed when placed in the fixed fixture assembly of the horizontal machining center, which easily leads to poor machining accuracy. This results in the need for multiple round trips for machining. Furthermore, the positions and angles of the connecting rod small end, connecting rod shaft, and connecting rod shaft connection are different for different models of connecting rod workpieces. This requires the installation and removal of different fixed fixture assemblies for different models of connecting rod workpieces, resulting in extremely poor adaptability and seriously affecting production efficiency.
[0005] Therefore, a workpiece clamping device is proposed to address the above problems. Utility Model Content
[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a workpiece processing clamping device is proposed.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The workpiece processing clamping device of this utility model includes a clamping table and a protective sleeve fixedly installed on the two sides of the top of the clamping table. An automotive part is movably sleeved on the outer surface of one end of the protective sleeve. A soft pad ring is provided at the middle position of the bottom of the clamping table and movably overlaps the outer surface of the bottom of the automotive part. A limiting rod is fixedly connected to the inner wall of the protective sleeve. An elastic wire is fixedly connected to the inner wall of the protective sleeve and at one side edge of the limiting rod. A slider is fixedly connected to one end of the elastic wire and movably sleeved on the outer surface of the limiting rod. A support rod is fixedly connected to the inner wall of the slider. A swing arm is movably sleeved on the outer surface of the support rod.
[0008] Preferably, an overlap pad is provided on the other end of the swing arm, and a support plate is fixedly connected to the top surface of the swing arm and at one edge of the overlap pad.
[0009] Preferably, the top inner wall of the overlapping pad is movably overlapped with the arc-shaped soft plate, and a limiting rod two is fixedly connected to the back of the arc-shaped soft plate and movably sleeved on the outer surface of the swing arm.
[0010] Preferably, one end of the second limiting rod is movably overlapped on the outer surface of the support plate, and a pushing claw is fixedly connected to the outer surface of the second limiting rod and at one edge of the overlapping pad.
[0011] Preferably, an elastic wire 2 disposed on the outer surface of the support plate is movably sleeved on the outer surface of the limiting rod 2.
[0012] Preferably, an anti-slip soft block that is movably attached to the outer surface of the arc-shaped soft plate is fixedly connected to the outer surface of the automotive parts.
[0013] Preferably, one end of the protective sleeve is provided with a raised opening, and the inner wall of the raised opening is movably connected to the outer surface of the swing arm.
[0014] Preferably, a circular groove is provided at the top center of the clamping platform, and a hydraulic push pump is provided on the bottom surface of the clamping platform at the bottom center of the circular groove. The output end of the hydraulic push pump is fixedly connected to the bottom surface of the soft pad ring.
[0015] The beneficial effects of this utility model are:
[0016] This utility model provides a workpiece processing clamping device. When clamping automotive parts, the bottom surface of the automotive parts is overlapped on the top surface of the overlap pad. At this time, the weight of the automotive parts is used to generate a downward pushing force on one end of the swing arm, and the one end of the swing arm swings on the surface of the support rod. The sliders on both ends of the support rod slide towards the inner wall of the protective sleeve, and the bottom surface of the automotive parts overlaps on the top surface of the soft pad ring. At the same time, the elastic wires on the inner wall of the protective sleeve push the sliders horizontally in the opposite direction, so that the slider on the outer surface of the limiting rod extends towards the middle position of the clamping table, thereby achieving a tight clamping effect on the surface of the automotive parts.
[0017] This utility model provides a workpiece processing clamping device. When one end of the swing arm is tightly attached to the surface of the automotive part, the arc-shaped soft plate on the inner wall of the overlapping pad is attached to the surface of the automotive part, thereby increasing the adhesion between the arc-shaped soft plate and the surface of the automotive part. At the same time, the anti-slip soft block on the outer surface of the arc-shaped soft plate effectively compresses the surfaces of automotive parts of different shapes and sizes. When the automotive part is being processed, if the surface of the automotive part shakes, the arc-shaped soft plate pushes it in all directions, and the pushing claw on the outer surface of the limiting rod II compresses the elastic wire II with elastic force. The reverse pushing force of the elastic wire II causes the limiting rod II to extend and retract on the surface of the support plate, thereby buffering the slight shaking of the automotive part.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Specific implementation examples are given below.
[0028] Please see Figure 1 - Figure 6 This utility model provides a workpiece processing clamping device, including a clamping table 11 and a protective sleeve 12 fixedly installed on the top two sides of the clamping table 11. An automotive part 13 is movably sleeved on the outer surface of one end of the protective sleeve 12. A soft pad ring 113 is provided at the bottom middle position of the clamping table 11 and movably overlaps the bottom outer surface of the automotive part 13. A limit rod 122 is fixedly connected to the inner wall of the protective sleeve 12. An elastic wire 125 is fixedly connected to the inner wall of the protective sleeve 12 and at one side edge of the limit rod 122. A slider 123 is fixedly connected to one end of the elastic wire 125 and movably sleeved on the outer surface of the limit rod 122. A support rod 124 is fixedly connected to the inner wall of the slider 123. A swing arm 126 is movably sleeved on the outer surface of the support rod 124.
[0029] During operation, when clamping the car part 13, the bottom surface of the car part 13 is placed on the top surface of the overlapping pad a1. At this time, the weight of the car part 13 itself generates a downward pushing force on one end of the swing arm 126, causing one end of the swing arm 126 to swing on the surface of the support rod 124. The sliders 123 on both ends of the support rod 124 slide towards the inner wall of the protective sleeve 12, and the bottom surface of the car part 13 is placed on the top surface of the soft pad ring 113. At the same time, the elastic wire 125 on the inner wall of the protective sleeve 12 pushes the slider 123 horizontally in the opposite direction, causing the slider 123 on the outer surface of the limiting rod 122 to extend towards the middle position of the clamping platform 11, thereby achieving a tight clamping effect on the surface of the car part 13. At the same time, the gap generated when the slider 123 slides from the surface of the limiting rod 122 into the protective sleeve 12 can effectively clamp car parts 13 of different sizes.
[0030] Furthermore, such as Figures 1 to 6 As shown, an overlapping pad a1 is provided on the other end of the swing arm 126. A support plate a2 is fixedly connected to the top surface of the swing arm 126 and to one side edge of the overlapping pad a1. The inner top wall of the overlapping pad a1 is movably overlapping the arc-shaped flexible plate a6. A limiting rod a2 is fixedly connected to the back of the arc-shaped flexible plate a6 and is movably sleeved on the outer surface of the swing arm 126. One end of the limiting rod a3 is movably overlapping the outer surface of the support plate a2. A pushing claw a4 is fixedly connected to the outer surface of the limiting rod a3 and to one side edge of the overlapping pad a1. An elastic wire a5 is provided on the outer surface of the support plate a2. An anti-slip soft block a7 is fixedly connected to the outer surface of the arc-shaped soft plate a6 and is movably attached to the outer surface of the car part 13. A curved opening 121 is provided on one end of the protective cover 12. The inner wall of the curved opening 121 is movably connected to the outer surface of the swing arm 126. A circular groove 111 is provided at the top center of the clamping platform 11. A hydraulic push pump 112 is provided on the bottom surface of the clamping platform 11 and at the bottom center of the circular groove 111. The output end of the hydraulic push pump 112 is fixedly connected to the bottom surface of the soft pad ring 113.
[0031] During operation, when one end of the swing arm 126 is tightly pressed against the surface of the automotive part 13, the arc-shaped soft plate a6 on the inner wall of the overlapping pad a1 is pressed against the surface of the automotive part 13, thereby increasing the adhesion between the arc-shaped soft plate a6 and the surface of the automotive part 13. At the same time, the anti-slip soft block a7 on the outer surface of the arc-shaped soft plate a6 effectively compresses the surface of the automotive part 13 with different shapes and sizes. Furthermore, if the surface of the automotive part 13 shakes during processing, the arc-shaped soft plate a6 pushes it outwards, and the pushing claw a4 on the outer surface of the limiting rod a3 springs the elastic wire a5. The force of the compression, combined with the reverse pushing force of the elastic wire a5, causes the limiting rod a3 to extend and retract on the surface of the support plate a2, thereby buffering the slight shaking of the car part 13. Later, when peeling off the car part 13, the hydraulic push pump 112 pushes the soft pad ring 113 to lift the car part 13 upward. When the swing arm 126 is lifted upward, the elastic wire 125 pushes the slider 123, causing the slider 123 to slide on the surface of the limiting rod 122. As the swing arm 126 is continuously lifted, the car part 13 is peeled out from the inside of the overlapping pad a1.
[0032] Working principle: When clamping the car part 13, the bottom surface of the car part 13 is placed on the top surface of the overlapping pad a1. At this time, the weight of the car part 13 itself generates a downward pushing force on one end of the swing arm 126, and causes one end of the swing arm 126 to swing on the surface of the support rod 124. The sliders 123 on both ends of the support rod 124 slide towards the inner wall of the protective sleeve 12, and the bottom surface of the car part 13 is placed on the top surface of the soft pad ring 113. At the same time, the elastic wire 125 on the inner wall of the protective sleeve 12 pushes the slider 123 horizontally in the opposite direction, so that the slider 123 on the outer surface of the limiting rod 122 extends towards the middle position of the clamping platform 11, thereby achieving a tight clamping effect on the surface of the car part 13.
[0033] When one end of the swing arm 126 is tightly attached to the surface of the automotive part 13, the arc-shaped soft plate a6 on the inner wall of the overlapping pad a1 is attached to the surface of the automotive part 13, thereby increasing the adhesion between the arc-shaped soft plate a6 and the surface of the automotive part 13. At the same time, the anti-slip soft block a7 on the outer surface of the arc-shaped soft plate a6 effectively compresses the surface of the automotive part 13 with different shapes and sizes. When the automotive part 13 is being processed, if the surface of the automotive part 13 shakes, the arc-shaped soft plate a6 pushes it in all directions, and the pushing claw a4 on the outer surface of the limiting rod a3 compresses the elastic wire a5. The reverse pushing force of the elastic wire a5 causes the limiting rod a3 to extend and retract on the surface of the support plate a2, thereby buffering the slight shaking of the automotive part 13.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
