Description

Technical Field

[0001] The utility model relates to an equipment clamp, in particular to a valve body clamp of an electromagnetic reversing valve. Background Art

[0002] The solenoid reversing valve is a component used to control the flow direction of oil in the hydraulic system. There are certain technical requirements in the assembly process. During assembly, the valve body needs to be placed on the operating table first, and then the screw plugs are tightened and other components are installed. At present, there is no fixed fixture during assembly of the solenoid reversing valve, which will cause the valve body to move during assembly, making it difficult to position and affecting assembly efficiency. Every time a valve body is assembled, the workpiece must be moved, which wastes time, and the valve body may fall during the movement process, causing product loss and affecting personnel safety. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an electromagnetic reversing valve body clamp which can improve the assembly efficiency of the electromagnetic reversing valve body, has good positioning effect during the assembly process and is safe in operation.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: an electromagnetic reversing valve body clamp, comprising a bottom plate and at least two fixed clamping plates, at least two of the fixed clamping plates are vertically and parallel to each other in the front-to-back direction and fixed on the bottom plate, a two-way clamping piece is arranged in the middle of two adjacent fixed clamping plates, the bottom of the two-way clamping piece is fixedly connected to the bottom plate, the upper part of the two-way clamping piece is sequentially provided with a first push block, a driving locking block and a second push block from front to back, the driving locking block is used to simultaneously drive the first push block and the second push block to move in the opposite direction along the front-to-back direction, a first clamping groove is formed between the first push block and an adjacent fixed clamping plate, and a second clamping groove is formed between the second push block and an adjacent fixed clamping plate, when the two valve bodies are respectively clamped in the first clamping groove and the second clamping groove, the driving locking block maintains a locking state; a supporting block is arranged at the bottom of the two-way clamping piece, the The top of the support block is recessed and provided with a driving countersunk hole, and the bottom of the driving countersunk hole is downwardly opened with a locking screw hole, and the rear side of the first push block is provided with a first dovetail groove which is gradually inclined backward from top to bottom, and the front side of the driving locking block is integrally provided with a first trapezoidal sliding block which cooperates with the first dovetail groove, and the first trapezoidal sliding block is slidably arranged in the first dovetail groove, and the front side of the second push block is provided with a second dovetail groove which is gradually inclined forward from top to bottom, and the rear side of the driving locking block is provided with a second trapezoidal sliding block which cooperates with the second dovetail groove, and the second trapezoidal sliding block is slidably arranged in the second dovetail groove, and the bottom of the first push block is slidably arranged on the upper end surface of the front side hole wall of the driving countersunk hole, and the bottom of the second push block is slidably arranged on the upper end surface of the rear side hole wall of the driving countersunk hole, and the driving locking block is arranged above the middle part of the support block through a vertical displacement adjustment locking mechanism and moves in the driving countersunk hole in an up and down direction. When the driving locking block is moved downward by the vertical displacement adjustment locking mechanism, the first trapezoidal slider and the second trapezoidal slider on both sides of the driving locking block slide downward in the corresponding dovetail grooves respectively, thereby pushing the first push block and the second push block outward along the upper end surface of the hole wall of the driving countersunk hole.

[0005] Compared with the prior art, the advantage of the utility model lies in that the two clamping plates and the two-way clamping pieces cooperate with each other and can clamp two valve bodies at the same time for assembly. When in use, the two valve bodies are respectively placed in the first clamping groove and the second clamping groove, and the locking mechanism is adjusted by vertical displacement to drive the locking block to move downward, while driving the first push block and the second push block to move outward along the upper end surface of the hole wall of the driving countersunk hole, thereby cooperating with the fixed clamping plate to clamp the two valve bodies at the same time. After clamping, the locking position of the driving locking block is fixed by the locking position of the vertical displacement adjusting locking mechanism, thereby ensuring the clamping effect. The clamp has a simple structure and is easy to use. It can clamp at least two valve bodies at the same time for assembly, and the number of fixed clamping plates and two-way clamping pieces can be further increased as needed, thereby greatly improving the assembly efficiency.

[0006] The vertical displacement adjustment locking mechanism is a locking screw, and a clamping hole and an adjustment hole are sequentially provided in the middle of the driving locking block from top to bottom. The aperture of the clamping hole is larger than the aperture of the adjustment hole. The locking screw passes through the clamping hole and the adjustment hole sequentially from top to bottom and is screwed into the locking screw hole. The upper end head of the locking screw is crimped to the upper end surface of the step formed between the clamping hole and the adjustment hole. The bottom surface of the first dovetail groove is recessed outward to provide a first reset groove. The second The bottom surface of the dovetail groove is recessed outwardly to provide a second reset groove, and both sides of the lower part of the drive locking block are respectively provided with a first limit block and a second limit block protruding outward and fixed thereon, the first limit block extends into the first reset groove, and a first reset spring is elastically compressed between the lower part of the first limit block and the lower bottom of the first reset groove, the second limit block extends into the second reset groove, and a second reset spring is elastically compressed between the lower part of the second limit block and the lower bottom of the second reset groove. When the locking screw is rotated to move it downward along the locking screw hole, the upper end head of the locking screw presses downward to drive the locking block, which drives the first push block and the second push block to move outward to both sides. When the first push block and the second push block respectively cooperate with the corresponding fixed clamping plates to clamp the valve body, the locking screw is locked in the locking screw hole to keep the position of the driving locking block unchanged; when the valve body needs to be loosened, the locking screw is rotated upward. At this time, the driving locking block moves upward under the action of the reset spring, thereby driving the first push block and the second push block to shrink inward synchronously to loosen the clamping of the valve body. The clamping and loosening operations are very convenient; the locking screw usually uses a hexagon socket screw, which is convenient to rotate with the corresponding tool to ensure the locking effect, and it is also convenient to loosen.

[0007] The bottom of the front and rear sides of the fixed clamping plate are respectively fixed with external positioning blocks, and the bottom of the front and rear sides of the support block are respectively fixed with internal positioning blocks, and a limiting groove for limiting the forward and backward movement of the valve body is formed between the external positioning block and the adjacent internal positioning block. The bottom of the valve body is further limited to prevent movement during assembly to affect the assembly accuracy.

[0008] Four fixing clamps are arranged parallel to each other and vertically fixed on the bottom plate in the front-to-back direction. The whole fixture can hold six valve bodies at the same time and perform assembly operations at the same time, which greatly improves assembly efficiency.

[0009] The left and right sides of the fixed clamping plate are respectively raised in the front-rear direction to form clamping convex ribs, which improve the clamping force on the valve body, make the valve body more stable during the assembly process, and thus improve the assembly accuracy of the valve body parts.
