Description

Technical Field

[0001] The utility model belongs to the field of clamps, and in particular relates to a clamp for a shell. Background Art

[0002] The shell clamp is used to clamp the shell. The shell is a thin-walled product with an opening that connects the inside of the shell with the outside. The opening is used to assemble parts into the shell. There are mainly plastic shells, aluminum profile shells, sheet metal shells and stainless steel shells.

[0003] The existing shell clamp clamps the two sides of the outer wall of the shell. However, due to the different thickness of the outer wall of the shell, when the thin-walled shell is clamped and fixed, it will cause extrusion deformation to the shell, affecting the shell size and causing large processing errors. In addition, when processing threads and inner holes on the thin-walled shell, it is also easy to cause shell deformation.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a clamp for a shell, and solve the technical problems in the prior art.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A clamp for a shell, comprising: a clamping platform and a support plate, wherein the upper side of the clamping platform is provided with four opposite grooves, each of the four grooves is slidably fitted with a slider, and the clamping platform is provided with two moving components connected with the four sliders;

[0008] The support plate is located on the slider, and a fixing component corresponding to the support plate is installed on the slider;

[0009] Among them, a driving member that is rotatably matched with the two moving components is provided on one side of the clamping table.

[0010] Optionally, four through slots connected to the four grooves are provided in the clamping table, and the moving assembly includes a first tooth plate and a second tooth plate which are slidably fitted in two opposite through slots, and the first tooth plate and the second tooth plate are respectively connected to two of the sliders; an inner cavity connected to the four through slots is provided in the clamping table, and a rotating rod is rotatably fitted in the inner cavity, and a gear meshing with the first tooth plate and the second tooth plate is installed on the circumference of the rotating rod, and the first tooth plate and the second tooth plate are respectively located on both sides of the gear; a worm wheel is installed on the circumference of the rotating rod, and a worm meshing with the worm wheel is rotatably fitted in the inner cavity; the worm passes through the end of the clamping table and is connected to a driving member, and the driving member is a turning handle or a motor, which can make the four support plates move relative to each other and fit and support the inner wall of the thin-walled shell, thereby reducing the extrusion and deformation of the shell when the thin-walled shell is clamped and fixed.

[0011] Optionally, a mounting groove is provided on the upper side of the slider, and the fixing assembly includes a threaded hole provided on one side of the slider and connected to the mounting groove, and a fastening bolt threadedly engaged in the threaded hole, and the threaded end of the fastening bolt is in low contact with the support plate, so that the support plate can be disassembled and assembled on the slider, thereby facilitating replacement of the support plate according to the size of the shell.

[0012] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0013] By setting up two moving components, the driving member drives the four sliders to move relatively along the groove at the same time through the two moving components, so that the four support plates can move relatively to the inner wall of the thin-walled shell for support. On the one hand, the extrusion deformation of the shell when the thin-walled shell is clamped and fixed is reduced. On the other hand, the extrusion deformation of the shell when the threads and inner holes of the thin-walled shell are processed is reduced, thereby improving the processing accuracy of the shell. The support plate can be disassembled and assembled on the slider through the fixed component, so that the support plate can be replaced according to the size of the shell.
