Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, in particular to a multi-station pressure plate drilling and milling fixture. Background Art

[0002] A fixture, also known as a jig, is a device used to secure a workpiece during the manufacturing process, ensuring it occupies the correct position for construction or testing. Broadly speaking, any device used to quickly, conveniently, and safely mount a workpiece at any stage in the manufacturing process can be called a fixture. A fixture typically consists of a positioning element (to determine the correct position of the workpiece within the fixture), a clamping device, a tool guide (to determine the relative position of the tool and workpiece or guide the tool's direction), an indexing device (which enables the workpiece to be processed at multiple locations in a single setup and can be either rotary or linear), connecting elements, and a fixture base.

[0003] At present, the existing clamps need to use a large number of bolts, nuts and other parts to position and install the pressure plate. After the pressure plate is drilled and milled, a large number of bolts, nuts and other parts need to be removed to remove the drilled and milled pressure plate.

[0004] In the above solution, the entire process requires manual operation by the staff, the operation steps are relatively cumbersome, and it takes up a lot of the staff's time, resulting in low drilling and milling efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a multi-station pressure plate drilling and milling fixture. By providing a pressure plate fixture, the pressure plate can be automatically positioned and installed, solving the problem of complicated operating steps in the existing technology, thereby saving time and improving the drilling and milling efficiency of the pressure plate.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A multi-station pressure plate drilling and milling fixture includes a base, an upper end of the base is fixed with a mounting shell, the upper end of the mounting shell is provided with multiple groups of pressure plate fixtures, the multiple groups of pressure plate fixtures are symmetrically arranged into two groups, the pressure plate fixture includes a fixture body fixed to the upper end of the mounting shell, the upper end of the fixture body is formed with a positioning groove that cooperates with the pressure plate, an extrusion mechanism is provided in the fixture body, and the extrusion mechanism includes an extrusion assembly, a linkage assembly and a drive assembly.

[0008] When the pressure plate needs to be positioned and installed, place the pressure plate in the positioning groove so that the pressure plate can be positioned, then start the driving component, and under the action of the linkage component, drive the extrusion component to extrude the pressure plate so that the pressure plate is fixed in the required position, so that the pressure plate can be automatically positioned and installed. After the drilling and milling of the pressure plate is completed, start the driving component, and under the action of the linkage component, the extrusion component is reset so that the pressure plate can be removed.

[0009] By providing a pressing plate fixture, the pressing plate can be automatically positioned and installed, solving the problem of complicated operation steps in the prior art, thereby saving time and improving the drilling and milling efficiency of the pressing plate.

[0011] Through the above technical solution, when the pressure plate needs to be extruded, the driving component is started to drive one of the extrusion plates to move, and under the action of the linkage component, the two extrusion plates are driven to move inward or outward at the same time, so that the inner wall of the extrusion groove can fit tightly on the side wall of the pressure plate, thereby allowing the pressure plate to be extruded.

[0012] The utility model is further configured as follows: the linkage assembly includes a gear rotatably connected to the bottom of the clamp body, and the lower end of the extrusion plate is fixed with a rack that meshes with the gear.

[0013] Through the above technical solution, when it is necessary to drive the two extrusion plates to move inward or outward at the same time, the driving assembly is started to drive one of the extrusion plates to move, and the movement of one of the extrusion plates drives one of the racks to move, and the movement of one of the racks drives the gear to rotate, and the rotation of the gear drives the other rack to move, so that the other extrusion plate moves together, thereby driving the two extrusion plates to move inward or outward at the same time.

[0014] The utility model is further configured as follows: the driving assembly includes a cylinder fixed to the upper end of the base, a driving block is fixed on the protruding end of the cylinder passing through the mounting shell, an inclined sliding block is formed on the side wall of the driving block, and an inclined sliding groove is formed on the side wall of one of the extrusion plates to cooperate with the inclined sliding block.

[0015] Through the above technical solution, when it is necessary to drive one of the extrusion plates to move, the cylinder is started to drive the driving block to move. At the same time, under the action of the inclined slider and the inclined slide groove, the driving block can drive one of the extrusion plates to move left and right when it moves up and down.

DETAILED DESCRIPTION

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] The following references Figures 1 to 4 The present utility model will be described.

[0028] A multi-station pressure plate drilling and milling fixture includes a base 1, an installation shell 2 is fixed to the upper end of the base 1, and multiple groups of pressure plate fixtures are provided on the upper end of the installation shell 2. The multiple groups of pressure plate fixtures are symmetrically arranged into two groups. The pressure plate fixture includes a fixture body 3 fixed to the upper end of the installation shell 2, and the upper end of the fixture body 3 is formed with a positioning groove 301 that cooperates with the pressure plate. An extrusion mechanism is provided in the fixture body 3, and the extrusion mechanism includes an extrusion component, a linkage component and a drive component.

[0029] When the pressure plate needs to be positioned and installed, the pressure plate is placed in the positioning groove 301 so that the pressure plate can be positioned. Then the driving component is started, and under the action of the linkage component, the extrusion component is driven to extrude the pressure plate so that the pressure plate is fixed in the required position. The pressure plate can be automatically positioned and installed. After the drilling and milling of the pressure plate is completed, the driving component is started, and under the action of the linkage component, the extrusion component is reset so that the pressure plate can be removed.

[0030] By providing a pressing plate fixture, the pressing plate can be automatically positioned and installed, solving the problem of complicated operation steps in the prior art, thereby saving time and improving the drilling and milling efficiency of the pressing plate.

[0031] The extrusion assembly includes two extrusion plates 4 symmetrically inserted into the clamp body 3, and a guide groove 401 is formed on both sides of the extrusion plate 4. A guide block 5 that cooperates with the guide groove 401 is formed on the inner wall of the clamp body 3, and an extrusion groove 402 that cooperates with the pressure plate is formed on the upper end of the extrusion plate 4.

[0032] When the pressure plate needs to be extruded, the driving component is started to drive one of the extrusion plates 4 to move, and under the action of the linkage component, the two extrusion plates 4 are driven to move inward or outward at the same time, so that the inner wall of the extrusion groove 402 can fit tightly on the side wall of the pressure plate, thereby squeezing the pressure plate.

[0033] The linkage assembly includes a gear 6 rotatably connected to the bottom of the clamp body 3 , and a rack 7 meshing with the gear 6 is fixed to the lower end of the extrusion plate 4 .

[0034] When it is necessary to drive the two extrusion plates 4 to move inward or outward at the same time, the driving assembly is started to drive one of the extrusion plates 4 to move. The movement of one of the extrusion plates 4 drives one of the racks 7 to move. The movement of one of the racks 7 drives the gear 6 to rotate. The rotation of the gear 6 drives the other rack 7 to move, so that the other extrusion plate 4 moves together, thereby driving the two extrusion plates 4 to move inward or outward at the same time.

[0035] The driving assembly includes a cylinder 8 fixed to the upper end of the base 1, and a driving block 9 is fixed on the protruding end of the cylinder 8 passing through the mounting shell 2. An inclined slider 10 is formed on the side wall of the driving block 9, and an inclined groove 403 that cooperates with the inclined slider 10 is formed on the side wall of one of the extrusion plates 4.

[0036] When it is necessary to move one of the extrusion plates 4, the cylinder 8 is started to drive the driving block 9 to move. At the same time, under the action of the inclined slider 10 and the inclined slide groove 403, the driving block 9 can drive one of the extrusion plates 4 to move left and right when it moves up and down.

[0037] A dovetail block 901 is formed on the side wall of the driving block 9 , a connecting block 11 is fixed to the upper end of the mounting housing 2 , and a dovetail groove 1101 that cooperates with the dovetail block 901 is formed on the side wall of the connecting block 11 .

[0038] Ensure that the driving block 9 does not deflect or vibrate when moving.

[0039] Working principle:

[0040] When the pressure plate needs to be positioned and installed, the pressure plate is placed in the positioning groove 301 so that the pressure plate can be positioned, and then the cylinder 8 is started to drive the driving block 9 to move. At the same time, under the action of the inclined slider 10 and the inclined slide groove 403, the driving block 9 can drive one of the extrusion plates 4 to move when it moves. The movement of one of the extrusion plates 4 drives one of the racks 7 to move, and the movement of one of the racks 7 drives the gear 6 to rotate. The rotation of the gear 6 drives the other rack 7 to move, so that the other extrusion plate 4 moves together, so that the inner wall of the extrusion groove 402 can fit tightly on the side wall of the pressure plate, so that the pressure plate can be fixed in the desired position. After the drilling and milling of the pressure plate is completed, the driving assembly is started, and under the action of the linkage assembly, the extrusion assembly is reset, so that the pressure plate can be taken out.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
