Description

Technical Field

[0001] The utility model belongs to the field of electrophoresis suspension tools, and particularly relates to an anti-breakdown device for electrophoresis suspenders. Background Art

[0002] The painting electrophoresis suspension tool is a device used to suspend workpieces (such as automobile bodies, hardware parts, etc.) in an electrophoresis tank during the electrophoresis painting process. It generally consists of a suspender and a hoisting component. The suspender is fixedly connected to the hoisting component through bolts, and the hoisting component is connected to the workpiece.

[0003] In long-term production practice, there are certain defects at the connection between the suspender and the hoisting component. For example, the threaded surface of the bolt and the suspender form a hollow structure, and the current generated when the suspension tool (cathode) touches the electrophoresis solution during the descending process (anode) causes the breakdown of the suspender. Over time, the suspender is severely damaged, which also affects the stability of the operation of the suspension tool. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an anti-breakdown device for electrophoresis suspenders, which effectively solves the problem of the breakdown of the suspender caused by the current generated when the suspension tool touches the electrophoresis solution during the descending process.

[0005] The utility model provides an anti-breakdown device for electrophoresis suspenders, including:

[0006] A fixing plate, which is attached to the suspender body and is connected to the hoisting component;

[0007] Two insulating plates, with the fixing plate and the suspender body arranged between the two insulating plates; and

[0008] Fasteners, which are used to connect the suspender body, the fixing plate and the insulating plates together. The fasteners include bolts, nuts and insulating sleeves sleeved on the bolts. The bolts and the insulating sleeves pass through the fixing plate, the insulating plates and the suspender body.

[0009] Optionally, a narrow groove is formed in the middle of the fixing plate, and the suspender body is arranged in the narrow groove to form a structure for clamping the suspender body.

[0010] Optionally, the insulating sleeve is screwed to the bolt.

[0011] Optionally, the length of the insulating sleeve does not exceed the width when the fixing plate, the insulating plates and the suspender body are combined together.

[0012] Optionally, a plurality of corresponding through holes are formed in the fixing plate, the insulating plates and the suspender body for setting the fasteners.

[0013] Optionally, the plurality of through holes are distributed in a rectangular array.

[0014] Optionally, the through hole on one of the insulating plates is a countersunk hexagon hole for setting the nut.

[0015] Optionally, the diameter of the insulating sleeve is 5 - 20 mm, and the thickness is 2 - 6 mm.

[0016] Optionally, the thickness of the insulating plate is 5 - 25 mm.

[0017] The beneficial effect of the present utility model is that the insulating plate and the insulating sleeve effectively separate the direct contact between the bolt and the fixing plate and the sling body, thus solving the problem of the current generated after the sling touches the electrophoresis liquid during the lowering process of the lifting tool, which causes the breakdown of the sling, avoiding serious damage to the sling, ensuring the stability of the long-term operation of the lifting tool, and of course improving the service life of the lifting tool.

[0022] As Figure 1 shown, an electrophoresis sling anti-breakdown device provided by the present utility model includes: a fixing plate 110, two insulating plates 120 and a fastener 130. Among them, the fixing plate 110 is attached to the sling body 1.1, and the fixing plate 110 is connected to the hoisting component; the fixing plate 110 and the sling body 1.1 are arranged between two insulating plates 120; the fastener 130 is used to connect the sling body 1.1, the fixing plate 110 and the insulating plate 120 together. The fastener 130 includes a bolt 131, a nut 132 and an insulating sleeve 133 sleeved on the bolt 131. The bolt 131 and the insulating sleeve 133 pass through the fixing plate 110, the insulating plate 120 and the sling body 1.1.

[0023] Compared with the prior art, the electrophoresis sling anti-breakdown device provided by the utility model effectively separates the bolt 131 from direct contact with the fixing plate 110 and the sling body 1.1 through the insulating plate 120 and the insulating sleeve 133, thus solving the problem of breakdown of the sling caused by the current generated after the sling touches the electrophoresis liquid during the lowering process of the lifting tool, avoiding serious damage to the sling, ensuring the stability of the long-term operation of the lifting tool, and of course improving the service life of the lifting tool.

[0024] In one embodiment, a narrow groove is formed in the middle of the fixing plate 110, and the sling body 1.1 is arranged in the narrow groove to form a structure for clamping the sling body 1.1. In this way, under the action of the fastener 130, the fixing plate 110 is closely attached to the sling, avoiding misalignment friction between the two.

[0025] In one embodiment, the insulating sleeve 133 is screwed to the bolt 131. In this way, the contact surface between the insulating sleeve 133 and the bolt 131 is larger. When lifting a workpiece, it is not easy to cause damage to the insulating sleeve 133 due to extrusion, and the insulating sleeve 133 and the bolt 131 can be firmly assembled together in advance, making it easier to perform subsequent assembly operations.

[0026] In one embodiment, the length of the insulating sleeve 133 does not exceed the width when the fixing plate 110, the insulating plate 120 and the sling body 1.1 are combined together, so that both the bolt 131 cap and the nut 132 can be attached to the insulating plate 120, which is beneficial to the stability of the overall structure.

[0027] In one embodiment, the fixing plate 110, the insulating plate 120 and the sling body 1.1 are all provided with a plurality of corresponding through holes 121 for setting the fastener 130. The specific number of through holes 121 can be selected according to the actual situation, and the stability of the overall structure shall be ensured.

[0028] In one embodiment, the plurality of through holes 121 are arranged in a rectangular array. Preferably, 6 - 8 through holes 121 are divided into two even columns.

[0029] In one embodiment, please refer to Figure 2 , the used through hole 121 is a round hole, and the specific diameter is designed according to needs and is not limited.

[0030] In one embodiment, please refer to Figure 3 , the through hole 121 on one of the insulating plates 120 is a hexagonal countersunk hole for setting the nut 132. In this way, the nut 132 placed in the through hole 121 can be restricted from rotating, so that the fastener 130 can be installed only by screwing the bolt 131, without the need for an additional wrench to fix the nut 132.

[0031] In one embodiment, the diameter of the insulating sleeve 133 is 5 - 20 mm, and the thickness is 2 - 6 mm. Within this range, the strength of the insulating sleeve 133 is appropriate and does not significantly reduce the overall structural strength.

[0032] In one embodiment, the thickness of the insulating plate 120 is 5 - 25 mm, ensuring sufficient strength while having good durability and insulation.

[0033] Those of ordinary skill in the art should understand that the discussion of any of the above embodiments is only exemplary and is not intended to imply that the scope of the present application is limited to these examples; within the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of one or more embodiments of the present application as described above, which are not provided in detail for the sake of brevity.

[0034] One or more embodiments of the present application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application shall be included within the scope of protection of the present application.
