Description

Technical Field

[0001] The utility model relates to the technical field of alloy resistor production, in particular to a simple sandblasting auxiliary fixture. Background Art

[0002] Alloy resistors refer to resistors that use alloys as current media. They have the characteristics of low resistance, high precision, low temperature coefficient, resistance to impact current, and high power. They are widely used in precision instruments, military products, aerospace electronics, new energy photovoltaic products, automobiles, etc.

[0003] The production process of alloy resistors is generally divided into the steps of sheet stamping, laser resistance repair, epoxy molding, molding channel cutting, surface sandblasting, code printing, curing, and pelletizing. Among them, during the surface sandblasting work, the product on the material strip needs to be sandblasted on both sides. At present, the masking sandblasting work is basically carried out by relying on jigs.

[0004] For example, the Chinese patent CN216731347U of the prior art discloses a sandblasting jig and sandblasting equipment, comprising a base plate; a profiling jig disposed on the base plate; a workpiece positioning block disposed on the profiling jig; the workpiece positioning block cooperates with a first positioning hole on the workpiece; a cover plate, the workpiece is placed on the profiling jig, and the cover plate covers the workpiece; a reverse positioning block disposed on the cover plate; the reverse positioning block cooperates with a second positioning hole on the workpiece.

[0005] However, the use of the jig in the above-mentioned prior art is relatively inconvenient. After completing the sandblasting of one side of the product on the material strip, it is necessary to open the profiling jig and the cover plate so as to turn the material strip over, and then reassemble the profiling jig and the cover plate to sandblast the other side of the product on the material strip. The process is cumbersome and the work efficiency is low. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a simple sandblasting auxiliary fixture to improve the sandblasting efficiency.

[0007] To achieve the above purpose, the utility model adopts the following contents:

DETAILED DESCRIPTION

[0020] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] See also Figure 1 and Figure 2 As shown. The utility model embodiment proposes a simple sandblasting auxiliary fixture, including a substrate 1 and a cover plate 2. The surface of the substrate 1 is provided with a plurality of protruding product positioning pins 11. The product positioning pins 11 are generally designed to be enclosed in a rectangular shape, and the number and position of the product positioning pins correspond to the number and position of the reserved holes on the material strip product, that is, the material strip product is positioned on the product positioning pins; a plurality of magnets 12 are embedded on both sides of the surface of the substrate 1 to exert a magnetic attraction effect, and a plurality of equally spaced first openings 13 are formed in the middle of the substrate 1 along its length direction, and two adjacent first openings 13 are separated by a first dividing strip 14.

[0023] The cover plate 2 is magnetically matched with the base plate 1 through the magnet 12 to complete the assembly. The surface of the cover plate 2 is provided with a plurality of positioning holes 21 for corresponding insertion of the product positioning pins 11. The product positioning pins 11 can also cooperate with the positioning holes 21 to complete the accurate alignment of the base plate 1 and the cover plate 2. A plurality of equally spaced second openings 22 are formed in the middle of the cover plate 2 along its length direction, and two adjacent second openings 22 are separated by a second dividing strip 23. When the cover plate 2 is combined with the base plate 1, the first opening 13 is opposite to the second opening 22 and is equal in size, and the first dividing strip 14 is opposite to the second dividing strip 23.

[0024] When in use, the clamping effect of the material strip product is achieved through the magnetic cooperation of the substrate and the cover plate, and the area formed by the relative first opening and the second opening is the area on the corresponding material strip product to be sandblasted, avoiding sandblasting masking and improving the sandblasting quality; after single-sided sandblasting is completed, there is no need to remove the substrate and the cover plate, and the entire fixture can be directly flipped 180° to perform sandblasting on the other side.

[0025] In one embodiment, a reinforcing plate 3 can be added, and an opening 31 is provided in the middle of the surface of the reinforcing plate 3, the width of the opening is substantially the same as the width of the first opening, and the two ends of the opening do not extend inward beyond the positions of the first openings on both sides, and the outer frame shape of the reinforcing plate 3 is consistent with the outer frame shape of the substrate 1, and the reinforcing plate 3 is welded to the substrate 1. In this way, by adding a layer of reinforcing plate to the substrate, the overall structural strength of the substrate is improved, and the substrate is prevented from being excessively bent during the separation process from the cover plate, thereby affecting the strip product fixed therein.

[0026] The surfaces of the base plate 1 and the reinforcing plate 3 are both provided with welding positioning rings 16 (32) that can correspond to each other. The cooperation of the welding positioning rings facilitates the welding connection of the assembled base plate and the reinforcing plate.

[0027] In this embodiment, two spaced-apart first grooves 15 are formed on both sides of the substrate 1, and a second groove 24 is formed in the middle of both sides of the cover plate 2. By staggering the first groove and the second groove, when the cover plate and the substrate need to be disassembled after being assembled, the operator can perform manual separation work according to the positions of the first groove and the second groove, thereby improving the efficiency of manual separation of the substrate and the cover plate.

[0028] It should be noted that the base plate 1 and the cover plate 2 are both made of stainless steel, such as common carbon steel, which has low cost and good corrosion resistance, and the fixture will not be excessively worn during long-term sandblasting work.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here.
