Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 2, a drop assembly of a jaw hammer includes a weight 200 for hammering a workpiece and a hammer rod 300 engaged with the weight 200.

Referring to fig. 2 and 3, the weight 200 is provided with a vertical insertion hole 210, and four positioning grooves 220 are uniformly formed around the insertion hole 210. One end of the hammer lever 300 close to the workbench 110 is integrally formed with four limit blocks 310 slidably connected with the positioning grooves 220. The lower end of the positioning groove 220 is communicated with the accommodating groove 230, which facilitates the rotation of the limiting block 310, and the accommodating groove 230 is consistent with the positioning groove 220 in number and is in one-to-one correspondence with the positioning groove 220.

During inserting the hammer stem 300 into the inserting hole 210, when the limiting block 310 slides along the positioning groove 220 to abut against the bottom of the accommodating groove 230, the hammer stem 300 is rotated, so that the limiting block 310 is in clamping fit with the accommodating groove 230, and the side surface of the side wall of the accommodating groove 230 and the limiting block 310 away from the ground abuts against each other, thereby improving the stability of the inserting fit between the hammer stem 300 and the weight 200.

The falling assembly of the clamping hammer further comprises a guide sleeve 400, a sliding groove 410 in the vertical direction is formed in the outer side of the guide sleeve 400, a sliding block 120 connected with the sliding groove 410 in a sliding mode is arranged on the rack 100, and the sliding block 120 is welded on the rack 100 in the vertical direction to enable the guide sleeve 400 to be connected with the rack 100 in a sliding mode in the vertical direction. The side surface of the weight 200 is polygonal, preferably the weight 200 is rectangular, and the guide sleeve 400 is sleeved on the outer side of the weight 200, so that the weight 200 is not easy to rotate when in operation, thereby improving the stability of the connection between the weight 200 and the hammer rod 300.

The hammer rod 300 is detachably provided with a fastening device, the fastening device comprises a locking nut 320 and a positioning edge 420 which is integrally formed at one end of the guide sleeve 400 far away from the workbench 110, and the positioning edge 420 is sleeved on the outer side of the hammer rod 300 and is obliquely arranged with the hammer rod 300. The positioning edge 420 is provided with an external thread, and the locking nut 320 is sleeved outside the hammer rod 300 and is in threaded fit with the positioning edge 420. The positioning edge 420 is provided with four fastening grooves 430 along the vertical direction, the positioning edge 420 is annular, and the diameter of the positioning edge 420 is gradually increased towards the direction of the workbench 120. after the locking nut 320 is in threaded connection with the positioning edge 420, the positioning edge 420 is enabled to extrude the side surface of the hammer rod 300, and therefore the fastening performance of the connection between the guide sleeve 400 and the hammer rod 300 is improved.

The support block 240 is integrally formed on the weight 200, and one side of the support block 240 close to the weight rod 300 abuts against the guide sleeve 400, so as to provide a vertical support force for the guide sleeve 400 and reduce the stress on the connecting position of the positioning edge 420 and the locking nut 320.

In order to reduce the impact force of the hammer rod 300 received at the coupling position of the positioning edge 420 and the lock nut 320, the length of the receiving groove 230 in the vertical direction is equal to the length of the stopper 310 in the vertical direction.

The implementation principle of the embodiment is as follows: the locking nut 320 and the guide sleeve 400 are sleeved on the hammer rod 300, the sliding groove 410 is in sliding fit with the rack 100, the locking nut 320 is locked, and the hammer rod 300 is inserted into the insertion hole 210 until the hammer rod 300 abuts against the bottom of the accommodating groove 230. The hammer rod 300 is rotated to enable the limiting block 310 to be in clamping fit with the accommodating groove 230, then the locking nut 320 is opened to enable the guide sleeve 400 to fall down, the guide sleeve 400 is abutted to the supporting block 240, the locking nut 320 is screwed down to lock the guide sleeve 400 and the hammer rod 300, and the assembly of the hammer 200, the guide sleeve 400 and the hammer rod 300 is completed.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
