Description

Technical Field

[0001] This utility model relates to the field of assembly operation technology, and in particular to a fastener locking component. Background Technology

[0002] In current production line manufacturing processes, many products require assembly by tightening fasteners such as nuts or bolts. Taking tightening nuts as an example, the groove depth of a traditional socket tool is greater than the height of the nut. Therefore, in most cases, before the nut is fully tightened, the bottom of the socket tool is already in contact with the surface of the product. As the operator continues to turn the socket tool to tighten the nut, the bottom surface of the socket will scratch the surface of the product.

[0003] Therefore, this utility model is dedicated to developing a fastener locking component to solve the problem that existing socket tools easily scratch products when tightening fasteners.

[0004] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a fastener locking assembly that can effectively solve the problem of easily scratching products when using existing socket tools to tighten fasteners.

[0006] To achieve the above objectives, this utility model provides a fastener locking assembly, comprising:

[0007] Product fixture, wherein the top surface of the product fixture is provided with a workpiece groove for placing the product;

[0008] A sleeve assembly, wherein the bottom surface of the sleeve assembly is provided with a sleeve groove for inserting the head of a fastener; wherein the depth of the sleeve groove is smaller than the height of the head of the fastener.

[0009] Optionally, the sleeve assembly includes a sleeve head having the sleeve groove and a sleeve connecting rod for connecting the sleeve head to the rotary drive mechanism.

[0010] Optionally, the circumferential surface of the sleeve connecting rod is provided with a bit slot.

[0011] Optionally, the groove depth of the sleeve groove is a, and the head height of the fastener is b, where a ≤ 2 / 3b.

[0012] Optional, 1 / 3b≤a.

[0013] Optionally, the groove wall of the sleeve is coated with an anti-slip coating.

[0014] Optionally, the anti-slip coating is a rubber coating, a silicone coating, or a carbon fiber reinforced coating.

[0015] Optionally, the product fixture includes an inverted π-shaped bracket and a fixture body mounted on top of the inverted π-shaped bracket, wherein the top surface of the fixture body is provided with the workpiece groove.

[0016] The beneficial effects of this utility model are as follows: It provides a fastener locking assembly. When it is necessary to tighten the fastener onto the product, the product is first placed in the workpiece groove for fixation, and then the fastener is positioned. Next, the sleeve assembly is placed on the head of the fastener. Since the depth of the sleeve groove is smaller than the height of the head of the fastener, the head of the fastener cannot be completely inserted into the sleeve groove; only a portion can enter the sleeve groove. When the sleeve assembly is subsequently tightened, even if the fastener is tightened to the bottom, the bottom surface of the sleeve assembly is higher than the bottom surface of the head of the fastener. Therefore, the bottom surface of the sleeve assembly will not contact the surface of the product, thereby preventing the sleeve assembly from scratching the product.

[0017] Therefore, the fastener locking assembly provided by this utility model can effectively solve the problem that existing socket tools easily scratch products when tightening fasteners. Attached Figure Description

[0032] See Figure 1 This utility model provides a fastener locking assembly, including a product fixture 1 and a sleeve assembly 2.

[0033] The product fixture 1 includes an inverted π-shaped bracket 101 and a fixture body 102 mounted on the top of the inverted π-shaped bracket 101, wherein the top surface of the fixture body 102 is provided with a workpiece groove 1021 for placing the product.

[0034] See Figure 2 The sleeve assembly 2 includes a sleeve head 201 with a sleeve groove 2011 and a sleeve connecting rod 202 for connecting the sleeve head 201 to the rotary drive mechanism. By connecting the sleeve connecting rod 202 to the rotary drive mechanism, the sleeve assembly 2 can be driven to rotate by the rotary drive mechanism, thereby completing the automatic locking and loosening of the fastener.

[0035] The bottom surface of the sleeve head 201 is provided with a sleeve groove 2011 for inserting the head of the fastener; wherein the groove depth of the sleeve groove 2011 is smaller than the height of the head of the fastener.

[0036] When the fastener is a bolt, the head of the fastener is the hexagonal head of the bolt; when the fastener is a nut or bolt, the head of the fastener is the entire nut or bolt.

[0037] The fastener locking assembly provided in this embodiment allows for the following steps when fasteners need to be tightened onto a product: First, the product is placed in the workpiece groove 1021 for fixation. Then, the fastener is positioned, and the sleeve assembly 2 is placed over the head of the fastener. Since the depth of the sleeve groove 2011 is less than the height of the head of the fastener, the head of the fastener cannot fully enter the sleeve groove 2011; only a portion can enter. When the sleeve assembly 2 is subsequently tightened, even when the fastener is fully tightened, the bottom surface of the sleeve assembly 2 is higher than the bottom surface of the head of the fastener. Therefore, the bottom surface of the sleeve assembly 2 will not contact the surface of the product, thus preventing the sleeve assembly 2 from scratching the product.

[0038] Therefore, the fastener locking assembly provided by this utility model can effectively solve the problem that existing socket tools easily scratch products when tightening fasteners.

[0039] Optionally, the circumferential surface of the sleeve connecting rod 202 is provided with a bit slot 2021. The sleeve connecting rod 202 with the bit slot 2021 can be quickly plugged and unplugged into a rotary drive mechanism such as an electric drill, making assembly and disassembly operations convenient.

[0040] In this embodiment, the groove depth of the sleeve groove 2011 is a, the head height of the fastener is b, and 1 / 3b≤a≤2 / 3b.

[0041] If the groove depth is too large, it can easily scratch the product; if the groove depth is too small, the head of the fastener can easily come out of the sleeve groove. Extensive research and summarization have shown that satisfying 1 / 3b ≤ a ≤ 2 / 3b can both prevent the product from being scratched and prevent the head of the fastener from coming out of the sleeve groove.

[0042] Optionally, the groove wall of the sleeve groove 2011 is coated with an anti-slip coating. For example, the anti-slip coating is a rubber coating, a silicone coating, or a carbon fiber reinforced coating.

[0043] The aforementioned anti-slip coating increases friction and prevents slippage, thereby improving the coefficient of friction between the sleeve and the fastener head, thus providing better grip and stability when tightening or loosening the fastener.

[0044] In summary, the fastener locking assembly provided in this embodiment has the following advantages:

[0045] ① Anti-scratch design: By designing the groove depth of the sleeve groove 2011 to be smaller than the height of the fastener head, it is ensured that the bottom surface of the sleeve assembly 2 will not contact the surface of the product during tightening, thereby avoiding the problem of scratching the product.

[0046] ② Quick connection: The circumferential surface of the sleeve connecting rod 202 is provided with a bit slot 2021, which can be quickly plugged and unplugged into a rotary drive mechanism such as an electric drill, making it easy to operate and replace.

[0047] ③ Precise dimensional design: By specifying the ratio of the groove depth of the sleeve groove 2011 to the height of the fastener head (1 / 3b≤a≤2 / 3b), it is ensured that the product will not be scratched and the fastener head will not be dislodged from the sleeve groove 2011.

[0048] ④ Enhanced friction: The groove wall of the sleeve groove 2011 is coated with an anti-slip coating (such as rubber coating, silicone coating or carbon fiber reinforced coating), which increases friction and improves the stability and reliability of operation.

[0049] ⑤ Improve product quality: By avoiding scratches and improving the consistency of locking, the present invention helps to improve the appearance quality and assembly accuracy of the final product.

[0050] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.

[0051] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
