It should be noted that the terms "first," "second," and the like in the description and in the claims of the present application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

In one preferred embodiment of the present application, as shown in fig. 1 to 5, a trimming device for a rubber safety handle includes a base 1, a driving device 2, a cutting assembly 3 and a clamping assembly 4, wherein a placement area for placing a handle to be trimmed is provided on the base 1, the driving device 2 is mounted on the base 1, the cutting assembly 3 is mounted on an output end of the driving device 2, and the clamping assembly 4 is mounted on the base 1 and connected with the output end of the driving device 2.

When trimming the rubber handle, firstly, the handle to be trimmed is placed in the placement area, then the driving device 2 is started, the driving device 2 can drive the cutting assembly 3 and the clamping assembly 4 at the same time, but the cutting assembly 3 and the clamping assembly 4 have a sequential relationship with the handle, and it can be understood that: the driving device 2 can be used for leading the clamping assembly 4 to clamp and fix the handle in the placement area, and then the driving device 2 is also suitable for driving the cutting assembly 3 to trim the handle.

Therefore, the clamping and fixing of the handle and the cutting and trimming process can be realized simultaneously only through one driving device 2, so that the manufacturing cost and the production cost are greatly reduced, and the structure is simple and practical.

The specific structure and working principle of the driving device 2 are known to those skilled in the art, and thus are not described in detail herein; the common driving device 2 includes a hydraulic cylinder, a pneumatic cylinder, a linear motor and the like, and can be selected by a person skilled in the art according to actual needs. Of course, the cutting assembly 3 includes a cutter 301, as shown in fig. 2, the cutter 301 is mounted at the output end of the driving device 2, that is, the driving device 2 pushes the cutter 301 to advance and retract, so as to implement the process of trimming the injection molding edge of the handle.

In this embodiment, as shown in fig. 3, the clamping assembly 4 includes a pair of clamping rods 401 and a pair of sleeves 402, the clamping rods 401 are symmetrically rotatably mounted on two sides of the placement area through a rotating shaft 403, the sleeves 402 are mounted on the output end of the driving device 2, and the rotating shaft 403 is sleeved on the sleeves 402 and is matched with the sleeves through a guiding structure 7.

Specifically, when the handle is fixed, the driving device 2 can drive the sleeve 402 to axially move (towards the rotating shaft 403), so that the rotating shaft 403 axially rotates through the guiding structure 7, and at this time, the two clamping rods 401 relatively rotate, so that one end of the clamping rod 401 abuts against the handle in the placement area, and the clamping fixation of the handle is realized. In the same way, if the driving device 2 drives the sleeve 402 to move away from the axis of the rotating shaft 403, the two clamping rods 401 will rotate in opposite directions and away from the handle in the placement area under the action of the guiding structure 7, so as to release the handle.

In this embodiment, as shown in fig. 4 and 5, the guiding structure 7 includes a guiding groove 701 and a guiding block 702, the guiding block 702 is mounted on the rotating shaft 403, the guiding groove 701 is disposed on the sleeve 402, and the guiding groove 701 includes a straight groove section 7011 and a spiral section 7012 which are communicated with each other.

It should be noted that when the handle is held by the holding rod 401, the holding rod 401 is kept stationary while held while cutting, since the subsequent cutting is also performed. Further, when the handle is fixed, the guide block 702 and the screw portion 7012 are engaged to rotate the grip lever 401. The guide block 702 and the straight slot section 7011 cooperate to hold the clamping bar 401 stationary while the handle trim is being performed.

In order to facilitate an understanding of how the driving device 2 drives the cutting assembly 3 and the clamping assembly 4 into action, the following description of the working principle thereof is provided:

when trimming a rubber handle, firstly, the handle to be trimmed is placed in a placement area, then a driving device 2 is started, the driving device 2 drives a cutter 301 to advance towards the handle, meanwhile, the driving device 2 also drives a sleeve 402 to move along the direction of a rotating shaft 403, at the moment, a guide block 702 is matched with a spiral section 7012, and then the rotating shaft 403 is driven to rotate, and two clamping rods 401 relatively rotate and prop against the top end of the handle (at the moment, the clamping rods 401 can be in a parallel state with a base 1) to clamp and fix the handle; at this time, the cutter 301 is in a forward state, but the injection side of the handle is not cut.

When the driving device 2 continues to drive the sleeve 402 to move, the guide block 702 enters the straight groove section 7011 to be matched with the straight groove section, the clamping rod 401 keeps the clamping static state of the handle all the time, and at the moment, the cutter 301 advances to cut off and trim the injection molding edge of the handle. That is, the clamping assembly 4 clamps and fixes the handle under the driving of the driving device 2, and then the cutting assembly 3 trims the handle.

In this embodiment, as shown in fig. 4, a clamping portion 6 is provided at one end of the clamping bar 401, and of course, the clamping portion 6 is elastic, and when the handle is clamped and fixed, the clamping portion 6 can elastically deform and abut against the handle, thereby improving the clamping stability.

Of course, the clamping portion 6 has various structural forms, including but not limited to the following two types:

structure one: a rubber pad is installed at one end of the clamping bar 401, and is elastically deformed during clamping due to the fact that the rubber pad is made of elastic materials, so that the friction force and stability of clamping are increased. The structure is also suitable for the condition of higher requirement on the surface of the clamped object, and can effectively prevent scratch and damage.

And (2) a structure II: a clamping plate is installed at one end of the clamping bar 401 through an elastic member (spring), and the spring is elastically deformed during clamping so that the clamping plate can clamp an object. And because the deformation capability of the spring is larger, the spring can be suitable for clamping and fixing handles with different thicknesses.

It should be noted that both structures can meet the actual requirements, and those skilled in the art can select according to the actual situation.

In this embodiment, as shown in fig. 4, the clamping rod 401 preferably adopts an "L" structure, and it is understood that the clamping rod 401 has a vertical portion 4011 and a horizontal portion 4012 that are connected vertically, the vertical portion 4011 is connected to the rotating shaft 403, and one end of the horizontal portion 4012 can clamp and fix the handle.

Specifically, as shown in fig. 4, the horizontal portion 4012 includes a guide sleeve 40121, an inner rod 40122, and a limiting member 40123, the guide sleeve 40121 is mounted on the vertical portion 4011, and the inner rod 40122 is slidably mounted in the guide sleeve 40121.

It can be appreciated that the horizontal portion 4012 can perform telescopic length adjustment, so that the handles with different lengths can be clamped and fixed, and when the length adjustment of the horizontal portion 4012 is required, the limiting component 40123 can release the locking of the inner rod 40122; when the adjustment of the horizontal portion 4012 is completed, the limiting member 40123 can lock the inner rod 40122.

Of course, the specific structure of the limiting member 40123 is not limited, and only two specific structures are provided below for reference:

structure one (as shown in fig. 4): the limiting member 40123 includes a limiting screw, which is screwed with the guide sleeve 40121. When the inner rod 40122 is locked, the stop screw can be positively threaded until it abuts the inner rod 40122. When adjustment of the horizontal portion 4012 is desired, the limit screw is rotated in reverse spiral so that the limit screw is away from the inner rod 40122.

Structure two (not shown): the limiting member 40123 includes a limiting ring rotatably mounted at one end of the guide sleeve 40121, and the limiting ring is sleeved on the outer portion of the inner rod 40122 and is engaged with the outer portion by threads. It will be appreciated that the inner rod 40122 is now in a cylindrical configuration and is threaded with the stop collar. When the length of the horizontal portion 4012 needs to be adjusted, the limiting ring can be rotated forward or reversely in a spiral mode, and then under the action of threads, the inner rod 40122 can be adjusted in a telescopic movement mode along the inside of the guide sleeve 40121. When the adjustment is completed, the rotation of the limiting ring is stopped, and the inner rod 40122 can be locked under the action of the threads.

In this embodiment, as shown in fig. 2 and 3, a waste tank 5 may be further disposed on the base 1, and the injection molding edge waste trimmed by the handle may be discharged and collected for subsequent processing.

The foregoing has outlined the basic principles, main features and advantages of the present application. It will be appreciated by persons skilled in the art that the present application is not limited to the embodiments described above, and that the embodiments and descriptions described herein are merely illustrative of the principles of the present application, and that various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims. The scope of protection of the present application is defined by the appended claims and equivalents thereof.
