Description

Technical Field

[0001] This utility model relates to the field of liquid cooling flow channel processing technology, and in particular provides an automatic detachment protective drill chuck locking tool. Background Technology

[0002] Currently, in bench drills and other drill chucks, the locking key does not automatically eject after locking and tool removal. If the operator forgets to remove the locking key and it is in a blind spot, restarting the spindle can cause the locking key to be flung out at high speed, which can easily lead to injury. Summary of the Invention

[0003] The purpose of this application is to provide an automatic release protective drill chuck locking tool. By designing and modifying the locking key, the locking tool is automatically ejected with a pin structure, realizing the automatic ejection and release of the locking tool after use, thus preventing the occurrence of locking tool injury incidents and effectively protecting the safety of personnel, equipment and products.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an automatic detachment protective drill chuck locking tool, the tool comprising:

[0005] The key body is used to lock the locking tool, and the key body is provided with a stepped through hole;

[0006] The ejector pin mates with the fine-hole portion of the stepped hole;

[0007] A spring is placed inside the large hole of the stepped hole, with one end of the spring in contact with the ejector pin to provide the power for the ejector pin to be ejected.

[0008] The handle is fixed to the large hole end of the stepped through hole of the key body and is used to limit the other end of the spring.

[0009] The automatic detachment protective drill chuck locking tool provided by this utility model also has the following technical feature: the top of the ejector pin is provided with a boss that engages with the step of the stepped hole, and the diameter of the boss is larger than the diameter of the fine hole of the stepped hole and smaller than the diameter of the large hole of the stepped hole.

[0010] The automatic detachment protective drill chuck locking tool provided by this utility model also has the following technical feature: the length of the ejector pin is greater than the length of the fine hole portion of the key body, and the length difference is not less than 5mm.

[0011] The automatic detachment protective drill chuck locking tool provided by this utility model also has the following technical feature: the large hole end of the stepped through hole of the key body is provided with a through hole for one end of the handle to pass through.

[0012] The automatic detachment protective drill chuck locking tool provided by this utility model also has the following technical feature: the preload of the spring is not less than 1KG.

[0013] The automatic detachment protective drill chuck locking tool provided by this utility model also has the following technical feature: the fitting gap between the ejector pin and the fine hole portion of the stepped hole is 0.05-0.1mm.

[0014] Beneficial effects

[0015] The automatic detachment protective drill chuck locking tool provided by this utility model has been redesigned and modified to automatically eject the locking tool with a pin structure. This ensures that the locking tool automatically ejects and detaches after use, preventing injuries caused by the locking tool and effectively protecting the safety of personnel, equipment, and products.

[0016] The automatic detachment protective drill chuck locking tool provided by this utility model is designed and modified from the original equipment locking key. The modification is simple, convenient and low cost. A stepped hole is drilled in the center of the key body shaft to form a sliding sleeve and spring chamber. The structure is simple and easy to modify. The ejector pin is designed with an ejector pin head, which serves as both a spring seat and prevents the ejector pin from falling out. The handle is used to press and fix the spring, which provides both locking torque and spring fixation, and provides spring preload. Attached Figure Description

[0024] like Figure 1 As shown in the figure, this application embodiment provides an automatic detachment protective drill chuck locking tool, the tool comprising:

[0025] Key body 2 is used to lock the locking tool, and the key body 2 is provided with a stepped through hole;

[0026] The ejector pin 4 mates with the fine hole portion of the stepped hole;

[0027] Spring 3 is placed inside the large hole of the stepped hole, and one end of spring 3 is in contact with the ejector pin 4 to provide the power for ejecting the ejector pin 4.

[0028] The handle 1 is fixed to the large hole end of the stepped through hole of the key body 2 and is used to limit the other end of the spring 3.

[0029] In some embodiments, the top of the ejector pin 4 is provided with a boss that engages with the step of the stepped hole, the diameter of which is larger than the diameter of the narrow hole of the stepped hole and smaller than the diameter of the large hole of the stepped hole.

[0030] In some embodiments, the length of the ejector pin 4 is greater than the length of the fine hole portion of the key body 2, and the length difference is not less than 5mm.

[0031] In some embodiments, the large end of the stepped through hole of the key body 2 is provided with a through hole for one end of the handle to pass through.

[0032] In some embodiments, the preload of the spring 3 is not less than 1 kg.

[0034] The working process of the automatic detachment protective drill chuck locking tool provided in any of the foregoing embodiments is as follows:

[0035] When the locking tool is used to lock the cutting tool, the ejector pin 4 is pressed into the key body 2. After use, the spring 3 pushes the ejector pin 4 out. The ejector pin 4 pushes against the drill chuck and pops itself out and separates from the drill chuck, effectively realizing the automatic disengagement of the locking tool and preventing the locking tool from being thrown out at high speed by the spindle rotation and causing injury.
