Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, in particular to a machining clamping and fixing device for an automobile EDM controller. Background Art

[0002] The external data storage device is EDM, and its outer shell is usually made of metal or plastic and prepared by casting. The semi-finished product after casting needs to be aligned for further processing to remove residual impurities on the shell.

[0003] The EDM controller shell is usually an irregular rectangular strip-shaped shell. When processing it after pouring, it is usually handled by personnel or fixed by a positioning device before processing. However, due to the irregular shape of the EDM controller shell, traditional positioning devices such as the processing positioning tool disclosed in Chinese patent document CN201611132054.9, in which the clamping head is driven to abut against the shell to achieve positioning by rotating the adjusting bolt, but each time the controller shell is placed, the placement position is different, which makes it easy to push the shell to move during subsequent positioning, resulting in poor positioning accuracy, which is not conducive to subsequent automated processing operations. To this end, we propose a clamping and fixing device for processing automotive EDM controllers. Utility Model Content

[0004] The utility model aims to provide a clamping and fixing device for machining an automobile EDM controller, so as to solve the problem that when the existing positioning device positions the housing, the housing is prone to deviation.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, a rubber pad is fixed on the pad, and the design of the rubber pad ensures that the EDM controller will not be damaged due to excessive squeezing after being clamped and positioned.

[0009] Preferably, a positioning column is installed on the positioning plate corresponding to the outer side of the EDM controller, and the designed positioning column can position the EDM controller to facilitate its precise placement.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figure 1-Figure 4 As shown, a clamping and fixing device for processing an automobile EDM controller in the figure includes a machine table 1, with rotating disks 2 installed at both ends of the machine table 1, a positioning plate 3 for placing the EDM controller fixed between the two rotating disks 2, and two groups of positioning components 4, each group of positioning components 4 is provided with six, four of which are distributed in pairs at both ends of the EDM controller, and the other two positioning components 4 are distributed on both sides of the EDM controller; and four pads 5 fixed on the positioning plate 3, the four pads 5 are distributed at both ends of the two EDM controllers, and cooperate with the positioning components 4 to clamp the two ends of the EDM controller;

[0024] In order to assist in placing the EDM controller housing, a positioning column 10 is installed on the positioning plate 3 corresponding to the outer side of the EDM controller.

[0025] Specifically, when positioning the EDM controller before processing, the personnel first place the EDM controller on the positioning plate 3, and limit the position through the positioning column 10, and place the two ends of the EDM controller on two pads 5 respectively, and then clamp the EDM controller through multiple positioning components 4 to achieve clamping and fixing, which is convenient for subsequent processing;

[0026] It should also be noted that the two rotating disks 2 can be rotated by the existing driving device, driving the positioning plate 3 to rotate at a specified angle, so as to facilitate the subsequent processing of the EDM controller housing clamped and fixed on the positioning plate 3.

[0027] The two groups of positioning components 4 can position two EDM controllers on the positioning plate 3 at one time, so that the two EDM controllers can be processed at one time.

[0028] For further reference, Figure 5 and Figure 6 The positioning assembly 4 includes an electric push rod 6, a clamping plate 7 and a support plate 8. The electric push rods 6 at both ends of the EDM controller are fixed to the bottom of the positioning plate 3. The output ends of the electric push rods 6 slide through the positioning plate 3. The support plates 8 at both ends of the EDM controller are fixed on the positioning plate 3. The electric push rods 6 at both sides of the EDM controller are fixed on the surface of the positioning plate 3. The support plates 8 at both sides of the EDM controller are fixed on the outer shell of the electric push rod 6. The output end of the electric push rod 6 is fixed to one end of the clamping plate 7 through a rotating shaft. Two connecting plates 9 are rotatably installed on the support plate 8 through the rotating shaft. The other ends of the two connecting plates 9 are rotatably connected to both sides of the clamping plate 7 through the rotating shaft.

[0029] The principle of the positioning component 4 to clamp the EDM controller is: the personnel first places the EDM controller housing on the positioning plate 3, and then extends the output ends of the electric push rods 6 in the multiple positioning components 4 to lift one end of the clamping plate 7 so that the other end is against the outside of the EDM controller housing, and presses down to clamp to complete the clamping positioning. When the processed EDM controller housing needs to be disassembled later, the output end of the electric push rod 6 moves downward, driving one end of the clamping plate 7 to move downward, thereby opening the end clamped by the EDM controller, and then the personnel can take out the EDM controller housing.

[0030] In this solution, in order to avoid damage caused by excessive pressure from the clamping plate 7, which would result in a large squeezing force between the EDM controller and the pad 5, a rubber pad is fixed on the pad 5 to provide cushioning to avoid damage caused by rigid contact between the pad 5 and the EDM controller.

[0031] like Figure 4 As shown, this is an embodiment for optimizing the placement of the EDM controller. In this embodiment, a positioning protrusion 11 is installed on the pad 5 through a bolt, and the positioning protrusion 11 is connected to the hole on the EDM controller housing;

[0032] It should be noted that through holes are provided on both ends of the EDM controller, and the two sides of the controller can be limited by the positioning column 10. In order to better limit the two ends of the EDM controller through the pad 5, positioning protrusions 11 that are compatible with the through holes on the controller are installed on the pad 5 by bolts, so that after the personnel place the EDM controller, the two ends and the two sides are respectively limited by the positioning protrusions 11 and the positioning columns 10. When the clamping plate 7 is pressed down for clamping, the EDM controller is not easy to deviate, thereby improving the accuracy of clamping and positioning.

[0033] like Figure 4 As shown, this is an embodiment for optimizing the placement of the EDM controller. In this embodiment, the positioning protrusion 11 and the positioning column 10 are both cylindrical structures with a thin top and a thick bottom. The design of this structure makes it easier for personnel to place the EDM controller, and the through hole and the positioning protrusion 11 on the EDM controller are also easier to insert.

[0034] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
