A type of non-adjustable freezer handle pull wire positioning fixture

Abstract

This case relates to a non-adjustable freezer handle positioning fixture, which includes a base plate that can be fixed to the work surface and multiple support plates arranged perpendicular to the base plate. The support plates are arranged sequentially from back to front as follows: a first positioning part that can position and pull the lower edge of the handle, a second positioning part that can position and pull the lower surface of the handle, and a third positioning part that can position and pull the upper surface of the handle. During operation, after the first positioning part is pulled, the freezer handle can be positioned to the second positioning part by rotating it clockwise forward. Then, it can be positioned to the third positioning part by moving it forward from the second positioning part. The whole process is a clockwise rotation and forward movement that is convenient for the handle, which reduces the risk of cosmetic damage during operation.

Description

Technical Field

[0001] This application relates to the field of hardware processing technology, specifically to the field of a non-adjustable freezer handle wire positioning fixture. Background Technology

[0002] Freezer handles are characterized by their multiple bends, varied appearances, and complex spatial curvatures. With increasing demands for aesthetic quality and texture, brushed metal, offering excellent decorative effects, has become a popular choice for exterior finishing.

[0003] However, traditional wire drawing operations typically employ a multi-station assembly line approach, requiring workers to process different surfaces of the handle sequentially from different positions. This frequent changing of processing angles and relocation of workstations can easily cause scratches or wear on the already treated surfaces.

[0004] Therefore, there is an urgent need for a positioning device that is simple in structure, requires no repeated adjustments, and can achieve multi-directional wire drawing on a single fixture. Summary of the Invention

[0005] In response to the above-mentioned needs, this application proposes a positioning fixture for the wire drawing of a freezer handle that does not require adjustment. The purpose is to combine the structural features of the freezer handle with a new fixture positioning structure to achieve multi-faceted wire drawing on a single fixture, thereby improving processing consistency and work efficiency.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] This application proposes a non-adjustable freezer handle wire drawing positioning fixture for wire drawing processing of freezer handles. The freezer handle has three external surfaces to be processed: a lower edge, a lower table surface, and an upper table surface. It includes a base plate that can be fixed to the work surface and multiple support plates that are perpendicular to the base plate.

[0008] The support plate is provided with a first positioning part that can position and pull the lower edge, a second positioning part that can position and pull the lower platform, and a third positioning part that can position and pull the upper platform from back to front. The second positioning part is provided with a second support surface that supports the lower platform, and the third positioning part is provided with a third support surface that supports the upper platform. The second support surface and the third support surface are on the same horizontal plane.

[0009] Therefore, considering the characteristics of the freezer handle's surface requiring wire drawing, the wire drawing process proceeds from back to front, sequentially working the lower edge, lower countertop, and upper countertop. During operation, after the wire drawing is completed at the first positioning section, the freezer handle can be positioned at the second positioning section by simply rotating it clockwise forward. Then, it can be moved forward from the second positioning section to the third positioning section. The entire process involves convenient clockwise rotation and forward movement, reducing the risk of surface damage during operation. Simultaneously, the second support surface supporting the lower countertop and the third support surface supporting the upper countertop are set to the same horizontal plane, ensuring consistent processing during wire drawing.

[0010] In some possible implementations, the first positioning part is provided with a first support surface that supports the lower edge, and the first support surface, the second support surface, and the third support surface are on the same horizontal plane.

[0011] In some possible implementations, the number of support plates is three.

[0012] In some possible implementations, the base plate has positioning holes on both sides for positioning with the work surface.

[0013] In some possible implementations, a side baffle is provided at at least one of the positioning holes to limit the longitudinal movement of the freezer handle.

[0014] In some possible implementations, the second positioning part and the third positioning part are respectively provided with a first clearance groove at their corresponding lower edges.

[0015] In some possible implementations, the second positioning part is provided with a second clearance groove at the junction of the lower platform and the rear edge. Attached Figure Description

[0022] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0023] It should be noted that the terms "front," "back," "left," "right," and "up" are used in the following description.

[0024] "Below" refers to the direction in the attached diagram, while "bottom" and "top," "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] Furthermore, unless otherwise explicitly stated and defined, the terms "installation," "connection," and "linking" shall be used interchangeably.

[0026] The term should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0027] Please refer to Figure 1 The freezer handle 100 involved in this application has a handle part 110. At this time, the corresponding floor surface 130 will become the appearance surface, and the upper edge 120 between the handle part 110 and the upper edge 130 will be the functional part for touching. Therefore, the handle part 110 and the upper edge 120 will be treated with anti-slip treatment such as frosting.

[0028] The lower countertop 140 and its lower edge 150, which form the handle position with the handle 110, are the exterior surfaces. Meanwhile, the rear edge 160 between the lower countertop 140 and the handle 11 does not require any exterior finishing. Therefore, a freezer handle 100 has three exterior surfaces: the upper countertop 130, the lower countertop 140, and the lower edge 150. The conventional method is to perform a wire-drawing process on each of these three surfaces separately in an assembly line. However, this wire-drawing process requires manual pressing of the wire from top to bottom, and repositioning can easily cause visual differences in the overall wire-drawing effect.

[0029] Please refer to the following for details. Figures 2 to 3 This application discloses a non-adjustable freezer handle wire-drawing positioning fixture, comprising a base plate 1 that can be fixed to a workbench, and multiple support plates 2 perpendicularly arranged to the base plate 1. Preferably, there are three support plates 2, respectively located at both ends and the middle of the base plate 1. The workbench mentioned here is a platform on which the wire-drawing equipment can operate, which is horizontal and has mounting holes or mounting strips. This is a conventional technical means in machine tools or wire-drawing equipment, and will not be described in detail.

[0030] Please refer to the reference. Figure 5and Figure 6 Considering the appearance of the freezer handle 100, the positioning fixture of this application is made of bakelite, which can be fixed to the work surface through positioning holes 11 on both sides of the base plate 1. Positioning can be achieved by tightening bolts at four points on the work surface, or by using positioning pins. The support plate 2 positions the freezer handle 100, and the base plate 1 has a mounting groove 12 for this purpose. After the support plate 2 is inserted into the mounting groove 12, it is fixed by tightening bolts from the bottom.

[0031] Furthermore, when using the positioning pin for fixing, a side baffle 3 is provided at at least one of the positioning holes 11 to limit the longitudinal movement of the freezer handle. The longitudinal movement is in the left-right direction shown in the figure.

[0032] Please refer to Figure 2 and Figure 5 The support plate 2 is provided with, from back to front, a first positioning part 21 for positioning and pulling the lower edge 150, a second positioning part 22 for positioning and pulling the lower surface 140, and a third positioning part 23 for positioning and pulling the upper surface 130. Further, the first positioning part 21 has a first support surface 211 supporting the lower edge 150, the second positioning part 22 has a second support surface 221 supporting the lower surface 140, and the third positioning part 23 has a third support surface 231 supporting the upper surface 130. At least the second support surface 221 and the third support surface 231 are on the same horizontal plane. Of course, the first support surface 211, the second support surface 221, and the third support surface 231 can also be on the same horizontal plane. Other limiting aspects can be achieved by combining the rear edge 160 of the freezer handle 100 and the lower surface 140 on the corresponding side, that is, limiting is performed on the basis of the flat surface of the pull.

[0033] Thus, considering the characteristics of the freezer handle 100's surface requiring wire drawing, the wire drawing process proceeds from back to front, sequentially processing the lower edge 150, lower countertop 140, and upper countertop 130. During operation, after the wire drawing process is completed at the first positioning part 21, the freezer handle 100 can be positioned at the second positioning part 22 by simply rotating it clockwise forward. Then, it can be positioned at the third positioning part 23 by moving it forward from the second positioning part 22. The entire process involves convenient clockwise rotation and forward movement, reducing the risk of surface damage during operation. Simultaneously, the second support surface 221 supporting the lower countertop 140 and the third support surface 231 supporting the upper countertop 130 are set to the same horizontal plane, ensuring consistent processing during wire drawing.

[0034] Please refer to Figure 3 and Figure 4As described above, the freezer handle 100 is bent and is limited at the lower edge 150, which is the exterior surface. To address this, the second positioning part 22 and the third positioning part 23 each have a first clearance groove 41 at the corresponding lower edge 150. Furthermore, the second positioning part 22 has a second clearance groove 42 at the junction of the lower countertop 140 and the rear edge 160 to prevent interference with the bent flange.

[0035] As stated above, this case protects a positioning fixture for a freezer handle that does not require adjustment. All technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
