Technical Field

[0001] The utility model relates to the technical field of clamping equipment, in particular to a clamping and fixing device for machining a cover plate of 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 shell of an EDM controller is usually composed of a shell and a cover plate. The shell of the controller is an irregular shell in the shape of a rectangular strip. The cover plate is usually prepared by casting. After preparation, the shape of the cover plate needs to be processed to change it to meet production needs. The cover plate needs to be positioned during the processing. 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 the outer edge of the cover plate is relatively thin. When abutting, the contact surface is small, which can easily cause damage to the contact part. To this end, we propose a clamping and fixing device for processing the cover plate of an automotive EDM controller. Utility Model Content

[0021] 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.

[0022] like Figure 1-Figure 3 As shown, a clamping and fixing device for processing an automobile EDM controller cover plate in the figure comprises a processing table 1, and also comprises a plurality of abutting units 2 fixed on the surface of the processing table 1, wherein the plurality of abutting units 2 are distributed in a linear array in the middle area of ​​the processing table 1, and the processing table 1 is used to place two EDM controller cover plates on both sides of the plurality of abutting units 2; and two rows of clamping units 3 installed on both sides of the processing table 1, and the two rows of clamping units 3 are used to clamp the outer edges of the two EDM controller cover plates against each other, and pads 4 are fixed on the surface of the processing table 1 corresponding to the positions of the clamping units 3 and the abutting units 2; and a plurality of supporting columns 5 fixed on the processing table 1, wherein the plurality of supporting columns 5 are distributed on both sides of the plurality of abutting units 2, and are used to support the bottom of the EDM controller cover plate;

[0023] Among them, in order to improve the supporting stability of the support column 5 on the EDM controller cover, the number of support columns 5 is preferably six, two of which are in contact with the inner walls at both ends of the EDM controller cover, and the other support columns 5 are in contact with the inner walls on both sides of the EDM controller cover.

[0024] Specifically, before processing the EDM controller cover, the personnel first place the cover on the six support columns 5, and use the support of the support columns 5 to support the cover and fit the inner wall to support and position the cover. Then, through the joint action of the abutment unit 2 and the clamping unit 3, the outer edges of the two EDM controller cover plates are clamped and abutted to achieve positioning, which is convenient for subsequent processing.

[0025] It should also be noted that the support columns 5 are all in the shape of a cylindrical structure that is thin at the top and thick at the bottom. This structural design makes it easy for personnel to place the EDM controller cover on multiple support columns 5.

[0026] For further reference, Figure 2 The clamping unit 3 includes an electric push rod 6 and a clamping plate 7. The electric push rod 6 is fixed on the processing table 1. The output end of the electric push rod 6 is connected to one end of the clamping plate 7 through a rotating shaft. A support plate 8 is fixed on the processing table 1. Two connecting plates 9 are rotatably installed on the support plate 8 through a rotating shaft. The outer ends of the two connecting plates 9 are rotatably connected to the clamping plate 7 through a rotating shaft.

[0027] The clamping unit 3 realizes the principle of clamping the outer edge of one side of the EDM controller cover: by lifting the electric push rod 6, one end of the clamping plate 7 is correspondingly lifted, so that the other end of the clamping plate 7 is pressed against the outer edge of the EDM controller cover to complete the clamping action. When canceling the clamping, only the electric push rod 6 needs to be retracted to rotate the clamping plate 7 from the horizontal clamping state to the inclined open state, which is convenient for personnel to place and remove the EDM controller cover.

[0028] For further reference, Figure 4 and Figure 5 The abutment unit 2 includes an electric push rod 12 fixed on the processing table 1, a push rod 13 is rotatably installed at the output end of the electric push rod 12, an adjustment plate 14 is fixed on the processing table 1, the push rod 13 slides through the adjustment plate 14, an abutment plate 15 abutting against the outer edges of the two EDM controller cover plates is fixed on the top of the push rod 13, an arc groove 16 is opened on the inner side of the adjustment plate 14, and a slider 17 adapted to the arc groove 16 is fixed on the outer side of the push rod 13;

[0029] The principle of the abutting unit 2 to clamp the outer edges of the two EMD controller covers is as follows: the electric push rod 12 moves downward, driving the push rod 13 to move downward, and the slider 17 on the outer side of the push rod 13 moves downward along the arc groove 16, and driving the abutting plate 15 to rotate and move downward. When it moves downward to abut against the outer edge of the EDM controller cover, the two ends of the abutting plate 15 are just abutted against the outer sides of the two EDM controller covers, completing the action of clamping the outer edges of the two EMD controller covers;

[0030] Similarly, by lifting the electric push rod 12, the push rod 13 moves up, and under the action of the slider 17, the push rod 13 completes the movement of moving up and rotating, so that the abutting plate 15 abutting against the outer edges of the two EDM controllers rotates and moves up, and stops after rotating 90°. At this time, it is easy for personnel to disassemble or place the EMD controller cover.

[0031] In this solution, in order to avoid damage caused by excessive downward pressure of the clamping plate 7 and the abutting plate 15, which would result in a large squeezing force between the outer edge of the EDM controller cover and the pad 4, a rubber layer is installed on the bottom of the clamping plate 7 and the abutting plate 15 and the surface of the pad 4.

[0032] like Figure 2 As shown, this is an embodiment of optimizing the positioning of the EDM controller cover. In this embodiment, two positioning platforms 10 are installed on the processing table 1 at both ends of the EDM controller cover, and through holes 11 are provided at both ends of the EDM controller cover. Positioning protrusions 18 plugged into the through holes 11 are installed on the positioning platform 10;

[0033] It should be noted that the through hole 11 on the outer edge of the EDM controller cover is plugged in through the positioning protrusion 18 threadedly plugged in on the positioning platform 10, so that the placement of the EDM controller cover is more stable and the position is more accurate after subsequent clamping.

[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.
