Description

Technical Field

[0001] The present application relates to the technical field of tool fixing, and more specifically, to a bottom plate spring pressing and fixing tool for metal sheet parts. Background Art

[0002] In the current field of mechanical processing, fixtures are indispensable auxiliary tools in the machining process. Their design rationality and practicality are directly related to machining efficiency, product positioning accuracy, and operator safety. Traditional fixtures, especially those that rely on manual clamping with vises, have exposed many shortcomings in practical applications.

[0003] From the perspective of machining efficiency, manual clamping with a vise often means that only one workpiece can be processed at a time. This one-by-one machining mode greatly limits production efficiency, especially in large-scale, batch production environments. This inefficient machining method has become a key factor restricting production capacity.

[0004] In terms of product positioning stability, manual vise clamping cannot guarantee absolute workpiece stability during machining. Due to the human factor in manually controlling the force and position of the clamp, the workpiece is prone to shifting or shaking, which not only affects machining accuracy but also may cause unnecessary wear on machining equipment and even lead to safety accidents.

[0005] Safety is another major issue that needs to be addressed with traditional fixtures. The manual clamping method using vises requires the operator to directly participate in the clamping process, which increases the risk during operation. Improper operation or accidental detachment of the workpiece can cause harm to the operator, seriously threatening safety on the production site. Existing fixtures have significant deficiencies in processing efficiency, product positioning stability, and safety. A new type of fixture is urgently needed to overcome these technical bottlenecks, improve processing efficiency, ensure stable product positioning, and protect the safety of operators. Utility Model Content

[0006] Based on the above problems, this application proposes an environmentally friendly dust removal and air separation screening machine to solve the technical problems of functional limitations, low integration, increased costs and low production efficiency of traditional environmentally friendly dust removal and air separation machines.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A bottom plate spring pressing and fixing tool for metal sheet parts, comprising a bottom plate, a support plate installed on the bottom plate, a sliding connection between the support plate and the bottom plate, a workbench fixedly installed on the support plate, a positioning block for positioning the workpiece installed on the workbench, a pull rod passing through the workbench, at least one pull rod is provided, a sliding connection between the pull rod and the workbench, a bearing plate provided between the workbench and the bottom plate, a fixed connection between the bearing plate and one end of the pull rod, a fixed baffle provided on the other end of each of the pull rods, a spring sleeved on the outer side of the pull rod, and a hydraulic cylinder for up and down displacement of the bearing plate provided between the workbench and the bearing plate.

[0009] In a specific possible implementation scheme, a slide groove is provided on the bottom plate, and the slide groove is T-shaped. A sliding block adapted to the slide groove is provided at the connection between the support plate and the slide groove.

[0010] In a specific possible implementation scheme, the diameter of the end of the pull rod close to the supporting plate is larger than that of the end close to the workbench, the spring is mounted on the end of the pull rod with a smaller diameter, one end of the spring is abutted against the bottom surface of the workbench, a section is formed at the junction of the section with a larger diameter of the pull rod and the section with a smaller diameter, and the other end of the spring is abutted against the section.

[0011] In a specific possible implementation scheme, the fixed baffle is mounted on the end of the pull rod exposed to the workbench by means of bolts.

[0012] In a specific feasible implementation scheme, the positioning block includes an edge positioning block, a middle positioning block and a corner positioning block. The edge positioning block is provided with two positioning recesses, the middle positioning block is provided with four positioning recesses, and the four positioning recesses are respectively provided at the four corners of the middle positioning block, and the corner positioning block is provided with one positioning recess.

[0013] In a specific feasible implementation scheme, at least one of the edge positioning block, the middle positioning block and the corner positioning block is provided, the corner positioning blocks are respectively installed at the four corners of the workbench, the edge positioning blocks are installed at the four edges of the workbench, and the middle positioning block is installed in the middle of the workbench in an array.

[0014] In a specific possible implementation manner, the recesses on each of the edge positioning blocks and each of the corner positioning blocks face the inner side of the workbench, and the recesses provided at the four corners of each of the middle positioning blocks face the four sides of the workbench respectively.

[0015] In a specific feasible implementation scheme, the bottom end of the hydraulic cylinder is fixedly connected to the bottom surface of the workbench, the end head of the hydraulic cylinder is fixedly connected to the upper surface of the supporting plate, the pull rods are arranged in rows, and the hydraulic cylinder is located between the pull rods in each row.

[0016] Positive effects of this utility model:

[0017] Traditional fixtures rely on vise-style hand clamping, which can only hold one workpiece at a time. However, the base plate spring pressing fixture of this application, through the design of a combined structure of a load plate, pull rod, and spring, can simultaneously clamp multiple workpieces, significantly improving processing efficiency and making it particularly suitable for large-scale, batch production environments.

[0018] Traditional fixtures are prone to workpiece shifting or shaking due to human factors such as manual clamping force and position control. This fixture uses a hydraulic cylinder to drive the load plate up and down, combined with the elastic support of tie rods and springs, to ensure absolute stability of the workpiece during machining, improve machining accuracy, reduce equipment wear, and prevent safety accidents.

[0019] Traditional fixtures require the operator to directly participate in the clamping process, increasing operational risks. This fixture, through its automated design, reduces operator involvement and operational risks. Furthermore, the spring and pull rod design provides a buffering effect, effectively minimizing harm to the operator even if the workpiece accidentally falls off. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example

[0029] like Figure 1-4 As shown, a base plate 1 spring 8 pressing tool comprises a base plate 1, a support plate 2 mounted on the base plate 1, the support plate 2 being slidably connected to the base plate 1, a workbench 3 fixedly mounted on the support plate 2, and a positioning block mounted on the workbench 3 for positioning the workpiece. The positioning block ensures the precise positioning and fixation of the workpiece. The positioning blocks include edge positioning blocks 13, middle positioning blocks 15, and corner positioning blocks 14. Positioning blocks of different shapes and positions can meet the needs of fixing the workpiece and provide comprehensive positioning support. The edge positioning block 13 is provided with two positioning recesses 12, the middle positioning block 15 is provided with four positioning recesses 12, and the four positioning recesses 12 are respectively arranged at the four corners of the middle positioning block 15. The corner positioning block 14 is provided with a positioning recess 12. The base plate 1 is provided with a T-shaped slide 10. The connection between the support plate 2 and the slide 10 is provided with a slider 11 that is compatible with the slide 10.

[0030] At least one edge positioning block 13, middle positioning block 15 and corner positioning block 14 is provided. The corner positioning blocks 14 are respectively installed at the four corners of the workbench 3, the edge positioning block 13 is installed at the four edges of the workbench 3, and the middle positioning block 15 is installed in the middle of the workbench 3 in an array.

[0031] The concave platforms on each edge positioning block 13 and each corner positioning block 14 face the inner side of the workbench 3 , and the concave platforms provided at the four corners of each middle positioning block 15 face the four sides of the workbench 3 respectively.

[0032] A tie rod 5 extends through the workbench 3, and a spring 8 is sheathed around the outside of the tie rod 5. The combination of the tie rod 5 and the spring 8 provides an effective pressing and cushioning mechanism, maintaining the stability of the workbench 3 and the workpiece during the pressing process. At least one tie rod 5 is provided, with the end of the tie rod 5 near the support plate 6 having a larger diameter than the end near the workbench 3. The spring 8 is sheathed around the smaller end of the tie rod 5. One end of the spring 8 abuts against the bottom surface of the workbench 3, and the junction of the larger and smaller diameter ends of the tie rod 5 forms a cross section, with the other end of the spring 8 abutting against the cross section.

[0033] A pull rod 5 is slidably connected to the workbench 3. A support plate 6 is disposed between the workbench 3 and the base plate 1. A hydraulic cylinder 9 is provided between the workbench 3 and the support plate 6 for vertical displacement of the support plate 6. The hydraulic cylinder 9 provides a reliable power source, precisely controlling the vertical displacement of the support plate 6. This allows for precise compression and release of the workbench 3 and the workpiece, improving work accuracy and efficiency.

[0034] The bottom end of the hydraulic cylinder 9 is fixedly connected to the bottom surface of the workbench 3 , and the end of the hydraulic cylinder 9 is fixedly connected to the upper surface of the bearing plate 6 . The pull rods 5 are arranged in rows, and the hydraulic cylinder 9 is located between the rows of pull rods 5 .

[0035] The supporting plate 6 is fixedly connected to one end of the pull rod 5 , and the other end of each pull rod 5 is provided with a fixed baffle 7 , which is installed on the end of the pull rod 5 exposed from the workbench 3 by bolts.

[0036] How it works

[0037] The workpiece is placed on the workbench 3 and accurately positioned and fixed by the edge positioning block 13 , the middle positioning block 15 and the corner positioning block 14 .

[0038] The hydraulic cylinder 9 is activated to push the carrying plate 6 downward. In this process, the spring 8 on the pull rod 5 is stretched, providing a buffer and pressing force to ensure that the workpiece remains stable during the pressing process.

[0039] When the workbench 3 and the workpiece reach the predetermined pressing position, the hydraulic cylinder 9 stops working. At this time, the spring 8 still maintains a certain tension state, providing a continuous pressing force for the workpiece.

[0040] When the workpiece needs to be released, the hydraulic cylinder 9 works in the reverse direction, pulling the carrying plate 6 upward. The spring 8 gradually returns to its original state, releasing the pressing force on the workpiece. At this time, the workpiece can be easily removed.

[0041] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
