Description

Technical Field

[0001] This utility model belongs to the field of motor housing processing technology, specifically relating to a servo motor housing processing fixture. Background Technology

[0002] Servo motor housing machining refers to a series of mechanical processing operations performed on the servo motor housing, including cutting, grinding, polishing, and welding, to achieve the required dimensions, shape, and surface quality. Servo motor housings are typically made of metal materials, such as aluminum alloy or stainless steel, to meet strength and corrosion resistance requirements. To prevent positional shifts during machining, fixtures are usually used to fix the motor housing in place, improving machining accuracy.

[0003] Patent CN213135925U discloses "an internal support fixture for machining motor housings, comprising a machining table and a base. The base is provided on the machining table, and a first gear is installed below the base. This internal support fixture for machining motor housings has a base on the worktable, and the first gear is installed at the bottom of the base. The position of the base can be adjusted under the action of a drive device to achieve all-round machining of the motor housing above the base. It is also equipped with a control handle, and the support block can support the motor housing according to different inner diameters of the motor housing, making it easy to operate."

[0004] Although the limiting groove in the prior art can limit the movement of components such as support blocks, metal shavings generated during the machining of the motor housing can easily enter the interior of the base through the opening of the limiting groove. The shavings entering the base may affect the operation of components such as gears, and the shavings entering the base are inconvenient to clean later. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a servo motor housing machining fixture in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A servo motor housing machining fixture includes a worktable and an inner support fixing mechanism mounted on the top of the worktable. The inner support fixing mechanism includes two sets of limiting frames fixedly mounted on the top of the worktable, two sets of inner support rods slidably mounted in the two sets of limiting frames, a frustum block that abuts against the two sets of inner support rods, and a connecting rod fixedly mounted on the bottom of the frustum block with its bottom end penetrating and extending into the interior of the worktable. The worktable is provided with a drive mechanism for driving the connecting rod to rise and fall. One end of the inner support rod is adapted to the outer inclined surface of the frustum block, and a spring is fixedly mounted on one side of the limiting frame for pushing the inner support rod toward the frustum block.

[0008] As a further optimization of this utility model, the driving mechanism includes a first electric push rod fixedly disposed between the bottom end of the connecting rod and the inner side of the worktable.

[0009] As a further optimization of this utility model, a connecting block is fixedly provided between the bottom of the inner support rod and one end of the spring, and a buffer pad is fixedly provided at the end of the inner support rod away from the frustum block.

[0010] As a further optimization of this utility model, baffles are fixedly provided on both sides of the top of the workbench, and a slag collection box is provided at one end of the workbench.

[0011] As a further optimization of this utility model, the top of the slag collection box is fixedly provided with a baffle that abuts against one side of the baffle, the top of the workbench is provided with a number of hooks that rotate and are attached to the top of the slag collection box.

[0012] As a further optimization of this utility model, a U-shaped base is rotatably provided at the bottom of one end of the workbench, and a plurality of inclined second electric push rods are rotatably provided between the bottom of the other end of the workbench and the inner side of the U-shaped base.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the drive mechanism and connected by the connecting rod, the frustum block can be moved up and down. After the frustum block is moved, it is guided by the outer inclined surface and, with the help of the spring force, will push the two sets of inner support rods to both sides. This allows the two sets of inner support rods to press and fix the outer casing from inside the motor casing. Since the top of the worktable does not have an opening, the debris generated during the processing of the motor casing will stay on the top of the worktable for later cleaning.

[0015] 2. By connecting the U-shaped base to one end of the worktable and using the extension and retraction of the second electric push rod, the worktable can be tilted by lifting or lowering one end. The debris on the top of the tilted worktable is easily collected in the slag collection box under its own weight and the guidance of the baffle, thus enabling quick cleaning of the debris on the top of the worktable. The slag collection box can be removed from one side of the worktable for centralized removal of debris, which is convenient and practical. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1-4 As shown, a servo motor housing processing fixture includes a worktable 1 and an inner support fixing mechanism. The inner support fixing mechanism is installed on the top of the worktable 1. In use, the servo motor housing is placed on the top of the worktable 1 so that the inner support fixing mechanism can enter the interior of the servo motor housing.

[0024] like Figure 1-3 As shown, the internal support fixing mechanism includes two sets of limiting frames 2 fixedly installed on the top of the workbench 1, two sets of internal support rods 21 slidably installed in the two sets of limiting frames 2, a frustum block 22 that abuts against the two sets of internal support rods 21, and a connecting rod 23 fixedly installed at the bottom of the frustum block 22 with its bottom end penetrating and extending into the interior of the workbench 1. The workbench 1 is provided with a drive mechanism for driving the connecting rod 23 to rise and fall. One end of the internal support rod 21 is adapted to the outer inclined surface of the frustum block 22. The drive mechanism includes a first electric push rod 24 fixedly installed between the bottom end of the connecting rod 23 and the inner side of the workbench 1. The connecting rod 23 can connect the first electric push rod 24 to the frustum block 22.

[0025] After the first electric push rod 24 extends and retracts, it will work with the connecting rod 23 to drive the frustum block 22 to move vertically. After moving, the frustum block 22 will push the two sets of inner support rods 21 to both sides under the guidance of its own outer inclined surface, so that the two sets of inner support rods 21 can press and fix the inner wall of the motor housing from inside the housing, thereby enabling the housing to be internally supported and fixed from inside the motor housing, so as to facilitate subsequent processing such as grinding of the outer wall of the motor housing.

[0026] like Figure 1-3As shown, a spring 25 is fixedly provided on one side of the limiting frame 2 to push the inner support rod 21 toward the frustum block 22. A connecting block 26 is fixedly provided between the bottom of the inner support rod 21 and one end of the spring 25. A buffer pad 27 is fixedly provided at the end of the inner support rod 21 away from the frustum block 22. The connecting block 26 can connect the inner support rod 21 and the spring 25. Under the elastic force of the spring 25, one end of the inner support rod 21 will always be in contact with the outer inclined surface of the frustum block 22, which is convenient for the frustum block 22 to press the inner support rod 21 laterally after vertical lifting and lowering. The buffer pad 27 can buffer and softly protect the inner wall of the motor housing when the inner support rod 21 presses against it, avoiding hard contact between the inner support rod 21 and the buffer pad 27, which may easily scratch the inner wall of the motor housing during the pressing process. The buffer pad 27 can be made of rubber or other materials with buffering effect.

[0027] like Figure 1-2 As shown, baffles 11 are fixed on both sides of the top of the workbench 1, and a slag collection box 3 is provided at one end of the workbench 1. The baffles 11 can block the top sides of the workbench 1, so that the debris on the top of the workbench 1 is not easy to fall from the baffles 11 to the ground.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the top of the slag collection box 3 is fixedly provided with a baffle 31 that abuts against one side of the baffle 11. The top of the workbench 1 is provided with several hooks 32 that rotate, and the top of the slag collection box 3 is provided with several hooks 33 that rotate and attach to the hooks 32. The baffle 31 is U-shaped and can partially cover the top of the slag collection box 3, so that when the workbench 1 is tilted, the debris on the top can easily fall into the slag collection box 3 under the protection and guidance of the baffle 11 and the baffle 31. By using the hooks 33 to attach the hooks 32, the slag collection box 3 can be quickly installed and is easy to operate.

[0029] like Figure 1-2 As shown, a U-shaped base 4 is rotatably provided at the bottom of one end of the workbench 1, and several inclined second electric push rods 41 are rotatably provided between the bottom of the other end of the workbench 1 and the inner side of the U-shaped base 4. The U-shaped base 4 can support the workbench 1. Through the connection between the U-shaped base 4 and one end of the workbench 1, and in conjunction with the extension and retraction of the second electric push rods 41, one end of the workbench 1 can be lifted or lowered, causing the workbench 1 to rotate and tilt. The debris that stays on the top of the tilted workbench 1 is easily collected in the slag collection box 3 under its own weight and the guidance of the baffle 11.

[0030] It should be noted that, when using this servo motor housing processing fixture, the servo motor housing is first placed on the top of the worktable 1 so that the inner support rod 21 and other inner support fixing mechanisms can enter the interior of the servo motor housing.

[0031] Then, the first electric push rod 24 can be controlled to extend and retract, in order to cooperate with the connection of the connecting rod 23 to drive the frustum block 22 to move vertically. After the frustum block 22 moves, under the guidance of its own outer inclined surface, it will push the two sets of inner support rods 21 to both sides, so that the two sets of inner support rods 21 can press and fix the inner side wall of the motor housing from the inside of the motor housing, thereby enabling the servo motor housing to be clamped and fixed from the inside of the motor housing, so as to facilitate subsequent processing such as grinding of the outer side wall of the motor housing.

[0032] Furthermore, through the connection between the U-shaped base 4 and one end of the workbench 1, and in conjunction with the extension and retraction of the second electric push rod 41, one end of the workbench 1 can be lifted or lowered, causing the workbench 1 to rotate and tilt. The debris remaining on the top of the tilted workbench 1 is easily collected in the slag collection box 3 under its own weight and the guidance of the enclosure 31 and the baffle 11, thus enabling quick cleaning of the debris on the top of the workbench 1. Subsequently, the hook 33 can be removed from the hook 32, thereby removing the slag collection box 3 from one side of the workbench 1 for centralized removal of debris, which is convenient for cleaning.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
