Description

Technical Field

[0001] This utility model relates to the field of automotive gas spring parts manufacturing technology, and in particular to a support and clamping device for opening square forks in automotive gas springs. Background Technology

[0002] A gas spring is an industrial component that can provide support, cushioning, braking, height adjustment, and angle adjustment. Gas springs are widely used in automobiles, serving as a support and cushioning mechanism.

[0003] To facilitate installation, gas springs in automobiles require connecting parts at their telescopic ends. Among these, the square fork is a common connecting part. During the production of the square fork, mounting holes need to be machined, usually using drilling equipment. During machining, the square fork needs to be fixed. However, existing fixing clamps lack internal and bottom supports. Furthermore, the downward pressure of the cutting tool during machining can cause some deformation of the square fork, resulting in the tilting of the machining holes, affecting roundness and concentricity. The chips produced after machining are also not effectively disposed of. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a support and clamping device for opening holes in the square fork of an automotive gas spring.

[0005] This utility model is achieved through the following technical solution:

[0006] A support and clamping device for opening holes in a square fork of an automotive gas spring includes a base, a cylinder frame, a first cylinder, a insert rod, a vertical plate, a clamping mechanism, a support mechanism, a square fork body, and an exhaust hole. The cylinder frame and the vertical plate are fixedly mounted on the upper surface of the base. The first cylinder is mounted on the back of the cylinder frame. The insert rod is fixedly mounted on the telescopic end of the first cylinder. The clamping mechanism is fixedly mounted on the inner side of the vertical plate. The support mechanism is located on the outer side of the bottom of the clamping mechanism. The square fork body is sleeved on the end of the insert rod. The exhaust hole is opened on the surface of the vertical plate. The clamping mechanism includes a locking block, a limiting plate, and a top rod. The limiting plate is fixedly mounted on both sides of the locking block, and the top rod is fixedly mounted on one end of the locking block.

[0007] In a preferred embodiment of the present invention, the support mechanism includes a support frame, a second hydraulic cylinder, a support cover, and a shield. The second hydraulic cylinder is installed on the inner side of the top of the support frame, the support cover is fixedly disposed on the telescopic end of the second hydraulic cylinder, and the shield is fixed to the outer side of one end of the support frame.

[0008] The support mechanism is mainly used to support and limit the opening at the end of the stacked fork body, and controls the square fork to reach the depth of the clamping mechanism through the top rod, thereby controlling the clamping position of the square fork body.

[0009] In a preferred embodiment of this utility model, the thickness of the locking block is consistent with the height of the opening at one end of the square fork body, the top and bottom of one end of the locking block are inclined, and the surface of the locking block is vertically provided with a knife-removing hole.

[0010] The thickness of the locking block matches the height of the opening at the end of the square fork body, ensuring the supporting effect of the locking block inside the opening at one end of the square fork body. The inclined surface at the top facilitates the locking block being engaged with the opening inside the square fork body.

[0011] In a preferred embodiment of the present invention, the support cover has a funnel-shaped structure, with a chip discharge hole on its outer side, and a slot that mates with the support cover is provided on the top of the support frame.

[0012] The support cover effectively supports the bottom of the fork body and has a clamping effect, while the chip removal hole facilitates the discharge of chips generated by the opening.

[0013] In a preferred embodiment of the present invention, an air inlet cover is installed on the outside of the exhaust hole located on the outside of the upright plate, a chip removal groove is provided on the top of the support frame, a slot for cooperating with the shield is provided on the top of one end of the support frame, and waist-shaped holes for easy installation are provided on both sides of the shield.

[0014] High-pressure airflow enters through the air inlet hood outside the exhaust vent, discharging debris from the debris discharge trough. Under the protection of the shield, the debris is easily collected.

[0015] In a preferred embodiment of this utility model, the distance between the limiting plates is matched with the width of the square fork body.

[0016] The beneficial effects of this utility model are:

[0017] This automotive gas spring square fork opening support clamping device effectively clamps the square fork. It effectively limits the position through side limit and internal support, effectively supports the inside of the square fork opening, and clamps the bottom support, thereby ensuring the roundness and concentricity of the opening of the mounting hole. The chips generated during processing can also be effectively handled to avoid waste accumulation. Attached Figure Description

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-4 The illustrated support and clamping device for opening a square fork in an automotive gas spring includes a base 1, a cylinder frame 2, a first cylinder 3, a rod 4, a vertical plate 5, a clamping mechanism 6, a support mechanism 7, a square fork body 8, and an exhaust hole 9. The cylinder frame 2 and the vertical plate 5 are fixedly mounted on the upper surface of the base 1. The first cylinder 3 is mounted on the back of the cylinder frame 2. The rod 4 is fixedly mounted on the telescopic end of the first cylinder 3. The clamping mechanism 6 is fixedly mounted on the inner side of the vertical plate 5. The support mechanism 7 is located on the outer side of the bottom of the clamping mechanism 6. The square fork body 8 is sleeved on the end of the rod 4. The exhaust hole 9 is opened on the surface of the vertical plate 5. The clamping mechanism 6 includes a locking block 61, a limiting plate 62, and a push rod 63. The limiting plate 62 is fixedly mounted on both sides of the locking block 61, and the push rod 63 is fixedly mounted on one end of the locking block 61.

[0025] Specifically, the support mechanism 7 includes a support frame 71, a second hydraulic cylinder 72, a support cover 73, and a shield 74. The second hydraulic cylinder 72 is installed on the inner side of the top of the support frame 71. The support cover 73 is fixedly installed on the telescopic end of the second hydraulic cylinder 72. The shield 74 is fixed to the outer side of one end of the support frame 71. The thickness of the locking block 61 is consistent with the opening height of one end of the square fork body 8. The top and bottom of one end of the locking block 61 are inclined. The surface of the locking block 61 has a vertically opened knife-removing hole. The support cover 73 has a funnel-shaped structure and a chip removal hole is opened on its outer side. The top of the support frame 71 has a slot that cooperates with the support cover 73. An air inlet cover is installed on the outer side of the exhaust hole 9 located on the outer side of the upright plate 5. The top of the support frame 71 has a chip removal groove. The top of one end of the support frame 71 has a slot that cooperates with the shield 74. The shield 74 has waist-shaped holes on both sides for easy installation. The distance between the limiting plates 62 is matched with the width of the square fork body 8.

[0026] In this embodiment, the square fork body 8 is first clamped. One end of the square fork body 8 is provided with a socket, and the other end is open. After the socket is inserted into the outside of the insert rod 4, the opening at one end of the square fork body 8 is adjusted to be horizontal. Then, the first hydraulic cylinder 3 is extended. At this time, the opening at the end of the square fork body 8 will be inserted into the outside of the locking block 61. The two sides of the square fork body 8 will be blocked and limited by the limiting plate 62 until the end of the top rod 63 contacts the bottom end of the opening at one end of the square fork body 8, thus completing the fixation of the square fork body 8. Then, the second hydraulic cylinder 72 extends, driving the support cover 73 to move upward. The support cover 73 squeezes the bottom of the square fork body 8, thereby preventing the bottom of the square fork body 8 from being squeezed by the tool and causing deformation, and also playing an auxiliary role in clamping the square fork body 8.

[0027] Furthermore, the drilling device operates, drilling from the top of the square fork body 8. After passing through the upper surface of the square fork body 8, it passes through the tool hole on the surface of the clamping block 61 and acts on the bottom of the square fork body 8 until the drill bit reaches the inner side of the top of the support cover 73, completing the drilling work. The waste chips generated during drilling will fall into the support cover 73. At this time, the air inlet cover installed on the outside of the exhaust hole 9 connects to the external air source. After the high-pressure airflow enters, it is discharged through the chip discharge hole on the surface of the support cover 73 and through the chip discharge groove on the surface of the support frame 71. After being guided by the shield 74, they are collected uniformly, completing the inner support, bottom support, effective positioning and clamping of the square fork body 8, and realizing the chip collection work after rapid processing.

[0028] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
