Description

Technical Field

[0001] The utility model belongs to the technical field of clamp equipment, in particular to a composite pressing clamp with elastic buffer. Background Art

[0002] Multilayer composite bearings are made up of multiple parts assembled and pressed together. Composite roller bearings are made up of two axial and radial roller bearings, which can reduce the volume of the bearings and simplify the installation structure, thereby reducing the manufacturing cost. When pressing the multilayer composite bearings, a composite pressing fixture is needed to clamp and fix them.

[0003] However, when the existing composite pressing fixture clamps the multi-layer composite bearing, they mostly use one-time hard contact and extrusion clamping, which is not conducive to buffering protection and step-by-step extrusion of the multi-layer composite bearing, and is easy to cause damage to parts and reduce product quality. Utility Model Content

[0012] Compared with the prior art, the composite pressing fixture with elastic buffer provided by the utility model supports the multi-layer composite bearing through the fixture unit, and the support sliding assembly presses the multi-layer composite bearing. After the multi-layer composite bearing is assembled, the multi-layer composite bearing is placed inside the storage slot on the carrier plate, and the hydraulic rod on the lower surface of the support frame in the support sliding assembly drives the pressing plate to press down longitudinally.

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figures 1 to 3As shown, it is a schematic diagram of the structure of the composite pressing fixture with elastic buffer provided by the utility model. The composite pressing fixture with elastic buffer includes a base unit 10, a clamp unit 20 arranged on the base unit 10 and used to be placed on the workpiece 1, a supporting sliding component 30 arranged between the base unit 10 and the clamp unit 20, and an auxiliary guide unit 40 arranged between the base unit 10 and the clamp unit 20. The composite pressing fixture with elastic buffer also includes some other functional modules, such as assembly components, etc., which should be technologies well known to those skilled in the art and will not be described in detail one by one here.

[0018] The base unit 10 includes a base 11, a plurality of guide rods 12 disposed on the base 11, and a plurality of first springs 13 disposed on the guide rods 12. The guide rods 12 and the first springs 13 are both used to guide the sliding support assembly 30 to slide, so the guide rods 12 and the first springs 13 will be described in conjunction with the sliding support assembly 30.

[0019] The base 11 includes a base body 111, a plurality of guide grooves 112 disposed on the base body 111, and two limit blocks 113 disposed on the base body 111. The guide grooves 112 cooperate with the auxiliary guide units 40 described below, and the limit blocks 113 limit the position of the carrier 22 described below.

[0020] The clamp unit 20 includes a telescopic rod 21 disposed on the base 11 , a carrier plate 22 disposed on one end of the telescopic rod 21 , a second spring 23 disposed on the telescopic rod 21 , and a storage slot 24 disposed on the carrier plate 22 .

[0021] The carrier plate 22 is arranged parallel to the upper part of the base 11. The carrier plate 22 is connected to the telescopic rod 21. The telescopic rod 21 can be extended. The second spring 23 is sleeved on the telescopic rod 21. The two ends of the second spring 23 are respectively abutted between the carrier plate 22 and the base 11. The second spring 23 keeps the telescopic rod 21 in an extended state through its own elastic force. The storage slot 24 is used to accommodate the composite bearing. The storage slot 24 is a prior art

[0022] After the multi-layer composite bearing is assembled, the multi-layer composite bearing is placed inside the storage groove 24 on the carrier plate 22, and the pressure plate 33 is driven to press down longitudinally by the hydraulic rod 32 on the lower surface of the support frame 31 in the supporting sliding assembly 30. After the pressure plate 33 contacts the upper surface of the multi-layer composite bearing, the multi-layer composite bearing will press down longitudinally on the carrier plate 22, and the telescopic rod 21 at the bottom of the carrier plate 22 is shortened. The second spring 23 undergoes elastic deformation within the elastic limit, the shaft rod 9 rotates, and the guide block 8 slides along the guide groove 101 on the upper surface of the base 1. After the multi-layer composite bearing is subjected to pressure, the carrier plate 2 is pressed down relative to the base 1 until the bottom of the carrier plate 22 fits with the end face of the limit seat 13. The multi-layer composite shaft and the carrier plate 22 are in flexible contact, which has a good buffering and protection effect, and is step-by-step extrusion to improve product quality.

[0023] The support sliding assembly 30 includes a support frame 31 fixedly disposed on the base 11 , a hydraulic rod 32 disposed on the support frame, and a pressure plate 33 disposed on the hydraulic rod 32 .

[0024] The support frame 31 is used to support the hydraulic rod 32 and the pressure plate 33, so that the hydraulic rod 32 and the pressure plate 33 are arranged on the top of the carrier plate 22. The hydraulic rod 32 drives the pressure plate 33 to approach the carrier plate 22, so as to realize the composite bearing processing between the pressure plate 33 and the carrier plate 22. In addition, the outer contour of the support frame 31 is L-shaped, and a reinforcing rod 34 is arranged at the bending part of the support frame 31 to improve the strength of the support frame 31.

[0025] The pressing plate 33 is movably connected to the guide rod 12, and the pressing plate 33 abuts against the first spring 13, and the pressing plate 33 is assisted to reset under the elastic force of the first spring 13. The pressing plate 32 corresponds to the carrier plate 22, and during the processing, the pressing plate 32 and the carrier plate 22 are pressed together to realize the processing.

[0026] The pressing plate 33 includes a pressing plate body 331 and a plurality of guide holes 332 disposed on the pressing plate body 331. The guide rods 12 are inserted into the guide holes 332 to improve the stability of the pressing plate 33 during the lifting and sliding process.

[0027] The auxiliary guide unit 40 includes a plurality of rotating shafts 41 rotatably connected to one side of the carrier 22, and a plurality of sliders 42 respectively arranged at the free ends of the rotating shafts 41. Each of the rotating shafts 41 is tilted, and the sliders 42 are always accommodated in the guide grooves 112. During the processing of the clamp unit 20 and the supporting sliding assembly 30, the telescopic rod 21 at the bottom of the carrier 22 is shortened, and the sliders 42 slide along the guide grooves 112 on the upper surface of the base 11, thereby improving the sliding stability of the carrier 22. After the multi-layer composite bearing is subjected to pressure, the carrier 22 is pressed downward relative to the base 11 until the bottom of the carrier 22 fits with the end surface of the limit block 113, thereby limiting the processing position of the carrier 22.

[0028] Compared with the prior art, the composite pressing fixture with elastic buffer provided by the utility model supports the multi-layer composite bearing through the fixture unit 20, and the support sliding assembly 30 presses the multi-layer composite bearing. After the multi-layer composite bearing is assembled, the multi-layer composite bearing is placed inside the storage slot 24 on the carrier 22, and the hydraulic rod 32 on the lower surface of the support frame 31 in the support sliding assembly 30 drives the pressing plate 33 to press down longitudinally. After the pressing plate 33 contacts the upper surface of the multi-layer composite bearing, the multi-layer composite bearing will press the carrier 22 longitudinally, the telescopic rod 21 at the bottom of the carrier 22 is shortened, and the second spring 23 undergoes elastic deformation within the elastic limit. The multi-layer composite shaft and the carrier 22 are in flexible contact during the processing process, which has a good buffering and protection effect, and is extruded step by step to improve product quality.
