[0033] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0034] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0035] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0036] The embodiment of the present utility model provides a horizontal double-station fixture for a shell, such as Figure 2 and Figure 3 As shown, it includes a base 100, a first clamping device and a second clamping device. The base 100 includes a first workbench 110 and a second workbench 120 located below the first workbench 110. The first clamping device and the second clamping device are respectively arranged on the first workbench 110 and the second workbench 120. The first clamping device and the second clamping device can respectively clamp a shell 10 to form a double workstation. The first workbench 110 and the second workbench 120 are separated by a preset distance in the vertical direction, and the distance is determined by those skilled in the art based on actual conditions. Since the machine tool processes both ends of the shell 10 in the longitudinal direction, the first workbench 110 does not interfere with the processing of the shell 10 on the second workbench 120.

[0037] Since the first clamping device and the second clamping device both clamp the same housing 10, the first clamping device and the second clamping device can adopt the same structure. Figure 3 The structure of the first workbench 110 and the first clamping device is shown in FIG. The structure of the second workbench 120 and the second clamping device can be the same as Figure 3 The structures shown are identical. Both the first and second clamping devices include a pressing assembly 200 for pressing down and fixing the housing, a limiting assembly 300 for limiting movement of the housing along its width, a snap assembly 400 for snapping onto the ridge of the housing, a pressing assembly 500 for lifting the housing, a clamping assembly 600 for clamping the housing, and a positioning assembly 700 for positioning the lugs on the housing.

[0038] The first clamping device and the second clamping device of this embodiment can each clamp a shell 10, forming a double-station. The machine tool can process two shells 10 at the same time, meeting the processing requirements of multiple stations and improving production efficiency. At the same time, due to the relatively complex structure of the shell 10 of this embodiment, a single reinforcement method cannot stably clamp the shell 10. This embodiment can stably clamp the shell 10 through the coordinated cooperation of the pressing assembly 200, the limiting assembly 300, the snap assembly 400, the top pressing assembly 500, the clamping assembly 600, and the positioning assembly 700, ensuring the accuracy of subsequent processing. This is suitable for the complex structure of the shell of this embodiment.

[0039] In some embodiments, as Figure 3 and Figure 4 As shown, the pressing assembly 200 includes a pressing rod 210, a pressing rod driving mechanism 220, and a support rod 230. The pressing rod driving mechanism 220 is connected to one end of the pressing rod 210. The other end of the pressing rod 210 is a downward pressing end, which is used to press on the housing. The support rod 230 can be arranged vertically, with the top end of the support rod 230 positioned below the downward pressing end of the pressing rod 210. The pressing rod driving mechanism 220 is used to drive the downward pressing end of the pressing rod 210 to press the housing tightly against the support rod 230, thereby stabilizing the pressing and fixing of the housing.

[0040] The pressure rod drive mechanism 220 may include a pressure rod driver and a connecting rod mechanism, and the pressure rod driver may include an oil cylinder. Since the structure of the shell is relatively complex and its surface does not have a large flat surface, the pressure rod 210 and the support rod 230 can stably clamp the shell and adapt to the structure of the shell surface.

[0041] In some embodiments, as Figure 3 and Figure 5 As shown, the limiting assembly 300 includes two limiting plates 310 located on both sides of the shell, and a part of the shell is inserted between the two limiting plates 310. The two limiting plates 310 limit the movement of the shell along its width direction from both sides to play a limiting role.

[0042] Furthermore, the tops of the inner sides of the two limiting plates 310 that are close to each other form a guiding slope 320. In the downward extending direction, the spacing between the guiding slopes 320 of the two limiting plates 310 gradually decreases, so that the opening at the top between the two limiting plates 310 forms a gradually shrinking opening structure, which can guide the shell to be inserted between the two limiting plates 310, making it easier for the shell to be quickly installed on the clamp device.

[0043] In some embodiments, as Figure 3 and Figure 6As shown, the snap assembly 400 includes a snap seat 410, an elastic pin 420 and a snap member 430. The lower end of the snap member 430 is rotatably connected to the snap seat 410. A protruding snap block 440 is provided on the front side of the upper end of the snap member 430. The elastic pin 420 is fixed on the snap seat 410 and abuts against the rear side surface of the upper end of the snap member 430. The elastic pin 420 can apply an elastic force to the snap member 430. The snap block 440 is used to snap onto the convex edge of the shell.

[0044] When the shell is placed downward, the convex edge of the shell will abut against the snap block 440, causing the snap member 430 to rotate rearward and the elastic pin 420 to retract toward its rear side. When the convex edge of the shell moves to the bottom of the snap block 440, the elastic pin 420 is reset, the snap member 430 rotates forward, and the snap block 440 can be snapped onto the convex edge of the shell.

[0045] The buckle seat 410 is provided with a limiting mechanism for limiting the forward rotation angle of the buckle member 430, thereby preventing the upper end of the buckle member 430 from falling below the lower portion of the buckle seat 410. For example, a limiting groove 450 may be provided on the front side of the buckle seat 410, and the lower end of the buckle member 430 may be disposed in the limiting groove 450 and rotatably connected to the buckle seat 410. When the lower end of the buckle member 430 abuts the inner wall of the limiting groove 450, the forward rotation angle of the buckle member 430 may be limited. Therefore, by controlling the length of the lower end of the buckle member 430, the forward rotation angle of the buckle member 430 can be limited.

[0046] In some embodiments, as Figure 3 As shown, the push assembly 500 includes a push rod and a push rod driving mechanism connected to the push rod. The push rod driving mechanism is used to drive the push rod to push the shell upward. The push rod driving mechanism can specifically include an oil cylinder.

[0047] In some embodiments, as Figure 3 and Figure 7 As shown, the clamping assembly 600 includes two clamping rods 610 and two clamping rod driving mechanisms 620 respectively connected to the two clamping rods 610. The two clamping rods 610 are respectively arranged on both sides of the housing in the width direction. The two clamping rod driving mechanisms 620 are respectively used to drive the two clamping rods 610 towards each other or away from each other. When the two clamping rods 610 approach each other, they can clamp the housing. When the two clamping rods 610 move away from each other, the clamping of the housing is released. The clamping rod driving mechanisms 620 may include a cylinder.

[0048] In some embodiments, as Figure 3 and Figure 7 As shown, the positioning assembly 700 includes a positioning seat 710 , and the positioning seat 710 is provided with a positioning groove 720 extending in a vertical direction. The lug of the shell is used to be inserted into the positioning groove 720 to position the lug of the shell.
