Description

Technical Field

[0001] This utility model relates to the field of locking mechanisms, and in particular to a pull-type locking mechanism. Background Technology

[0002] In the field of machining, the term "broach-type" usually refers to a mechanism that uses tension to clamp or fix a workpiece. However, when existing broach-type locking mechanisms lock cylindrical workpieces, the subsequent machining processes cause some waste to splash onto the locking mechanism, affecting cleanliness. Furthermore, some waste splashes into the guide groove, affecting the normal use of the clamp.

[0003] To address the aforementioned problems, this application proposes a pull-type locking mechanism. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a pull-type locking mechanism. This utility model includes a cleaning mechanism to facilitate cleaning after use, thereby increasing the convenience and cleanliness of use.

[0006] (II) Technical Solution

[0007] To solve the above problems, this utility model provides a pull-type locking mechanism, including a base, a clamping part one fixedly installed on one side of the base, and a clamping part two slidably disposed on the other side of the base;

[0008] A linear actuator is fixedly mounted on the clamping part one, and the drive rod of the linear actuator is fixedly connected to the clamping part two to adjust the distance between the clamping part one and the clamping part two.

[0009] A guide shell that passes through the clamping part one is fixedly installed on the clamping part two. The guide shell is provided with a cleaning mechanism that cleans the base when the clamping part two moves away from the clamping part one.

[0010] Preferably, a guide block is slidably fitted inside the base, and the guide block is fixedly connected to the bottom of the clamping part two.

[0011] Preferably, the cleaning mechanism includes a notched tube and an auger blade. The notched tube is fixedly installed on the side of the guide shell, and the auger blade is located inside the notched tube and is rotatably connected to the cleaning mechanism through a rotating rod. The rotating rod is driven by the base.

[0012] Preferably, a rack is fixedly installed on the base, and a transmission gear that drives the rack is fixedly fitted on the rotating rod.

[0013] Preferably, a protective shell is fixedly installed on the flow guide shell.

[0014] Preferably, the linear actuator is a hydraulic cylinder or a pneumatic cylinder.

[0015] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0016] The cylindrical workpiece is placed on clamping part one. The linear actuator drives clamping part two to move toward clamping part one to clamp the cylindrical workpiece. As clamping part two moves toward clamping part one, it drives the guide shell to continuously pass through clamping part one. After clamping part two clamps the cylindrical workpiece, the protective shell fits against the side of clamping part one facing clamping part two, so as to guide the waste to the base. After processing is completed, the linear actuator drives clamping part two to separate from clamping part one, so that the transmission gear and rack drive the auger blades to rotate to clean the base, thereby removing the waste from the base and increasing the convenience of cleaning.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figure 1-3 As shown, the present invention proposes a pull-type locking mechanism, including a base 1, a clamping part 2 fixedly installed on one side of the base 1, and a clamping part 3 slidably disposed on the other side of the base 1. A guide block 7 is slidably sleeved inside the base 1, and the guide block 7 is fixedly connected to the bottom of the clamping part 3.

[0023] A linear actuator 4 is fixedly mounted on the clamping part 2, and the drive rod of the linear actuator 4 is fixedly connected to the clamping part 3 to adjust the distance between the clamping part 2 and the clamping part 3; the linear actuator 4 is a hydraulic cylinder or a pneumatic cylinder.

[0024] A guide shell 5 passing through the clamping part 2 is fixedly installed on the clamping part 3. The guide shell 5 is provided with a cleaning mechanism 6 that cleans the base 1 when the clamping part 2 moves away from the clamping part 2.

[0025] Specifically, the cleaning mechanism 6 includes a notched tube 61 and an auger blade 62. The notched tube 61 is fixedly installed on the side of the guide shell 5, and the auger blade 62 is located inside the notched tube 61 and is rotatably connected to the cleaning mechanism 6 through a rotating rod 63. The rotating rod 63 is driven by the base 1.

[0026] A notch is formed at the bottom of the notch tube 61 on the side facing the clamping part 2 3, so that when the notch tube 61 moves toward the clamping part 2 3, the waste debris enters the auger blade 62 through the notch.

[0027] To increase the stability of the transmission, a rack 64 is fixedly installed on the base 1, and a transmission gear 65 that drives the rack 64 is fixedly mounted on the rotating rod 63.

[0028] In an optional embodiment, a protective shell 66 is fixedly mounted on the flow guide shell 5.

[0029] When the protective shell 66 moves to the side of the clamping part 2, it fits against the clamping part 2. At this time, the other side of the protective shell 66 is inclined to guide the waste to the base 1.

[0030] In this invention, a cylindrical workpiece is placed on clamping part 2. The linear actuator 4 drives clamping part 3 to move toward clamping part 2 to clamp the cylindrical workpiece. When clamping part 3 moves toward clamping part 2, it drives the guide shell 5 to continuously pass through clamping part 2. After clamping part 3 clamps the cylindrical workpiece, the protective shell 66 fits against the side of clamping part 2 facing clamping part 3, so as to guide the waste to the base 1. After processing, the linear actuator 4 drives clamping part 3 to separate from clamping part 2, so that the transmission gear 65 and rack 64 are driven to rotate, thereby cleaning the base 1 and removing the waste from the base 1, thus increasing the convenience of cleaning.

[0031] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
