Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a rectangular frame jig. Background Art

[0002] For products that are prone to damage due to mutual collision and friction, when batch cleaning such products, it is necessary to pre-insert the products into Figure 1 the rectangular frame 1 as shown. During use, the products are sequentially inserted into one end of the rectangular frame 1, and then the jig is used to clamp the rectangular frame 1, and the whole is placed in a cleaning tank for cleaning. In order to improve the cleaning efficiency and cleaning effect, the jig can be connected to a rotating mechanism, and the rotating mechanism is used to rotate the jig and the rectangular frame 1. The problem is that: generally, the jig is an open-type jig for clamping the side wall of the rectangular frame 1, and the products may be thrown out during the rotation of the jig and the rectangular frame 1. Therefore, a new jig is designed in this solution to limit the products in the rectangular frame 1. Summary of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a rectangular frame jig, which can improve the stability of the rectangular frame and limit the products in the rectangular frame.

[0004] To achieve the purpose of the utility model, the following scheme is proposed:

[0005] A rectangular frame jig includes a control box and two symmetrically arranged clamping components.

[0006] A convex plate is respectively arranged around the top surface of the rectangular frame, and the orientation of the convex plate is parallel to the long axis direction of the rectangular frame;

[0007] The control box is used to control the distance between the two clamping components. Each clamping component includes a horizontal plate and two baffles respectively arranged at the ends of the horizontal plate. A clamping plate is arranged at the bottom inside the horizontal plate, and the clamping plate is used to clamp the side wall of the rectangular frame. A vertical plate is arranged at the top outside the horizontal plate, and the top of the vertical plate is connected to the control box. The two baffles are arranged in a horn shape, and the top surface of the baffle is used to support the corresponding convex plate;

[0008] When the top surface of the baffle supports the corresponding convex plate, in the vertical direction from top to bottom, the baffle blocks the end face of the rectangular frame to limit the products in the rectangular frame.

[0009] Further, the clamping assembly further includes a lead screw, a guide rod, and an inverted U-shaped plate. The bottom surface of the inverted U-shaped plate is closely attached to the horizontal plate. A first pipe and a second pipe are arranged in parallel inside the inverted U-shaped plate. One end of the lead screw penetrates through the vertical plate and is connected with a knob. The lead screw is in threaded fit with the first pipe. One end of the guide rod is fixedly connected to the vertical plate, and the guide rod is in sliding fit with the second pipe. Rack teeth are provided on the outer walls of the inverted U-shaped plate. One end of the baffle plate facing the horizontal plate is rotatably connected to the horizontal plate, and a gear is fixedly provided at this end of the baffle plate. The gear meshes with the corresponding rack teeth.

[0010] Further, an extension plate is provided at one end of the baffle plate facing the horizontal plate. The included angle between the extension plate and the baffle plate is an obtuse angle. Two limiting plates are provided on the extension plate. The gear is fixedly arranged between the two limiting plates. The lower limiting plate is rotatably connected to the horizontal plate.

[0011] Further, the baffle plate is provided with a plurality of horizontal through grooves in an array.

[0012] The beneficial effects of the present utility model are as follows: The baffle plate can not only support the convex plate and clamp the end face of the rectangular frame body, thereby improving the stability of the rectangular frame body, but also directly limit the product inside the rectangular frame body to prevent the product from being thrown out during the rotary cleaning process.

[0017] As Figure 2 shown, this embodiment provides a rectangular frame body fixture, including a control box 21 and two symmetrically arranged clamping assemblies.

[0018] The fixture is used to clamp the rectangular frame body 1. Four convex plates 11 are respectively arranged around the top surface of the rectangular frame body 1. The four convex plates 11 are distributed in a rectangular array, and the orientation of the convex plates 11 is parallel to the long axis direction of the rectangular frame body 1. The long axis direction of the rectangular frame body 1 is the direction in which the product is inserted.

[0019] The bottom of the control box 21 is connected to two clamping components for controlling the distance between the two clamping components. Each clamping component includes a horizontal plate 22 and two baffles 26 respectively arranged at the ends of the horizontal plate 22. At the bottom inside the horizontal plate 22, there is a clamping plate 221 for clamping the side wall of the rectangular frame 1. At the top outside the horizontal plate 22, there is a vertical plate 222, and the top of the vertical plate 222 is connected to the control box 21. The two baffles 26 in the clamping component are arranged in a horn shape, and the top surface of the baffle 26 is used to support the corresponding convex plate 11. That is to say, this fixture can not only use the clamping plate 221 to clamp the side wall of the rectangular frame 1, but also use the baffle 26 to clamp the end face of the rectangular frame 1 and support the convex plate 11, thus greatly improving the stability of the rectangular frame 1.

[0020] When the top surface of the baffle 26 supports the corresponding convex plate 11, in the vertical direction from top to bottom, the baffle 26 can block the end face of the rectangular frame 1. Therefore, the baffle 26 has multiple functions: one is to clamp the end face of the rectangular frame 1, the second is to support the convex plate 11, and the third is to limit the product inside the rectangular frame 1 to prevent the product from being thrown out. In order to improve the fluidity of the liquid in the cleaning tank, it is best to arrange a plurality of horizontal through grooves 263 on the baffle 26. Note that the through grooves 263 are arranged in a staggered manner with the product inside the rectangular frame 1, so that the baffle 26 can not only limit the product from being thrown out, but also be beneficial to the liquid flow.

[0021] For products of different sizes, rectangular frames 1 with adapted sizes need to be prepared. In the above scheme, the two horn-shaped baffles 26 are fixedly arranged and the angles are not adjustable, so the above fixture can only clamp rectangular frames 1 of one size. Therefore, in order to be able to clamp rectangular frames 1 of different sizes, the preferred way is to make the angles of the two horn-shaped baffles 26 adjustable. The specific implementation method is as follows:

[0022] As Figure 3 、 Figure 4 shown, the clamping component further includes a lead screw 23, a guide rod 24 and an inverted U-shaped plate 25. The bottom surface of the inverted U-shaped plate 25 is closely attached to the horizontal plate 22. Inside the inverted U-shaped plate 25, a first tube 251 and a second tube 252 are arranged in parallel. One end of the lead screw 23 passes through the vertical plate 222 and is connected with a knob 231. The lead screw 23 is in threaded cooperation with the first tube 251. One end of the guide rod 24 is fixedly connected to the vertical plate 222, and the guide rod 24 is in sliding cooperation with the second tube 252. Rack teeth 28 are arranged on the outer walls of the inverted U-shaped plate 25. One end of the baffle 26 facing the horizontal plate 22 is provided with an extension plate 261. The included angle between the extension plate 261 and the baffle 26 is an obtuse angle. Two limit plates 262 are arranged on the extension plate 261. The two limit plates 262 are arranged in upper and lower layers. A gear 27 is fixedly arranged between the two limit plates 262. The lower limit plate 262 is rotatably connected to the horizontal plate 22, and the gear 27 is meshed with the corresponding rack teeth 28.

[0023] When it is necessary to adjust the angles of the two horn-shaped baffles 26, rotate the knob 231 to make the lead screw 23 rotate. Since the inverted U-shaped plate 25 is restricted by the guide rod 24, the rotation of the lead screw 23 will cause the inverted U-shaped plate 25 to move linearly along the guide rod 24. When the inverted U-shaped plate 25 drives the rack 28 to move, it will cause the gear 27 to rotate, thereby adjusting the angle of the baffle 26. After the angle adjustment of the baffle 26 is completed, a condition needs to be met: when the clamping plate 221 clamps the side wall of the rectangular frame body 1, the baffle 26 just clamps the end face of the rectangular frame body 1 and supports the convex plate 11.

[0024] The above embodiments are only used to illustrate the technical idea and characteristics of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
