For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0035] The utility model provides a handle pressing device, by installing a pressing structure, a driving structure and a buffer structure on a support frame, when pressing the handle, the driving structure drives the pressing structure to perform linear reciprocating motion, so that the two shells of the handle are tightly pressed together, and the buffer mechanism is used to buffer the impact force when the pressing mechanism moves downward, so as to avoid the handle being damaged by the impact. By using this device, the assembly efficiency of the handle is effectively improved.

[0036] Specifically, Figure 1 , Figure 2 As shown, the handle pressing device includes a support frame 1, a pressing structure 2, a driving structure 4, and a buffer structure 5. The support frame 1 includes a flat support base 101, on which a fixing frame 102 is fixedly arranged, and the fixing frame 102 has left and right side walls and a top wall that are integrally fixedly connected, and the three side walls of the fixing frame 102 and the support base 101 enclose a pressing operation space. The pressing structure 2 is arranged in the pressing operation space and reciprocates linearly in the pressing space along a direction perpendicular to the support base 101 for pressing the handle 3; the driving structure 4 is arranged on the top of the fixing frame 102 for driving the pressing structure 2 to perform linear reciprocating motion; the buffer structure 5 is arranged in the pressing operation space for reducing the impact force of the pressing structure 2 falling, so as to prevent the pressing structure 2 from damaging the handle 3 during the process of pressing the handle 3.

[0037] A guide structure 6 is provided in the pressing operation space, and the pressing structure 2 is slidably matched with the guide structure 6. This facilitates the guiding of the pressing structure 2 to stably reciprocate linearly to ensure accurate pressing of the handle 3. In this embodiment, the guide structure 6 includes two guide posts relatively arranged on both sides of the pressing structure 2, the top of the guide post is fixedly connected to the top wall of the fixing frame 102, and the bottom end is fixedly connected to the support base 101, which can not only guide the pressing structure 2, but also maintain the stability of the pressing operation space.

[0038] The pressing structure 2 specifically includes an upper fixing block 201 and a lower fixing block 202. The upper fixing block 201 is slidably matched with the guide column by being sleeved on the outer side of the guide column at both ends, and the lower fixing block 202 is fixedly arranged on the support base 101 to support the pressed handle 3.

[0039] In order to accurately control the pressing stroke, ensure that the pressed handle 3 is evenly stressed, and avoid local stress concentration and easy damage, the pressing structure 2 also includes a pressing mold 7, which has an upper mold 701 and a lower mold 702. The upper mold 701 is detachably connected to the upper fixed block 201, and the lower mold 702 is detachably connected to the lower fixed block 202. The purpose of the detachable connection is to facilitate the replacement of molds of different models. The upper mold 701 has an upper cavity that is compatible with one shell of the handle 3, and the lower mold 702 has a lower cavity that is compatible with the other shell of the handle 3. When the upper mold 701 and the lower mold 702 are in contact, the upper cavity and the lower cavity form a accommodating cavity that is compatible with the handle 3. In this way, when pressing the handle 3, as long as the upper mold 701 and the lower mold 702 are just buckled, the upper and lower shells can be firmly connected.

[0040] Furthermore, the driving structure 4 uses an existing hydraulic cylinder, and a push rod of the hydraulic cylinder passes through the top of the fixing frame 102 and is fixedly connected to the pressing structure 2 .

[0041] The buffer structure 5 includes two coil springs 501, each guide column is sleeved with a coil spring 501, and the coil spring 501 is arranged below the upper fixed block 201. In this way, when the driving structure 4 drives the upper die 701 to descend rapidly, the upper fixed block 201 touches the coil spring 501, and the kinetic energy is reduced under the buffering of the coil spring 501, thereby preventing the instantaneous impact force of the upper die 701 from being too large to damage the handle 3.

[0042] Furthermore, the buffer structure 5 also includes a protective sleeve 502 and an extrusion structure 503. The protective sleeve 502 is sleeved on the outside of the coil spring 501 to effectively protect the coil spring 501. The top of the protective sleeve 502 is fixedly connected to the upper fixed block 201, and the extrusion structure 503 is set at the bottom of the protective sleeve 502 for extruding the coil spring 501.

[0043] like Figure 2 , Figure 3As shown, the extrusion structure 503 specifically includes a sliding cylinder 5031, which is sleeved on the guide column and slidably cooperates with the guide column. A stop ring 5032 is arranged on the top of the sliding cylinder 5031. The stop ring 5032 is limited to the bottom of the protective sleeve 502 to abut against the coil spring 501 and slide with the inner wall of the protective sleeve 502.

[0044] In this way, the buffer structure 5 as a whole moves back and forth along the guide column together with the upper fixed block 201. When the upper fixed block 201 moves upward, it carries the protective sleeve 502, the spiral spring 501, and the extrusion structure 503 to slide upward along the guide column, the pressing mold 7 is opened, and the docked handle 3 is placed in the lower cavity of the lower mold 702. The driving structure 4 drives the upper fixed block 201 to move downward, and the protective sleeve 502, the spiral spring 501, and the extrusion structure 503 move downward with the upper fixed block 201 until the bottom end of the extrusion structure 503 contacts After supporting the base 101, the extrusion structure 503 stops moving. At this time, the upper fixed block 201 continues to move downward, and the protective cover 502 and the coil spring 501 continue to move downward with the upper fixed block 201. The stop ring 5032 at the top of the extrusion structure 503 squeezes the coil spring 501 in the protective cover 502. After being squeezed, the coil spring 501 buffers the kinetic energy of the upper fixed block 201 and reduces the instantaneous impact force of the upper mold 701 contacting the handle 3. The upper mold 701 continues to move downward until it abuts against the lower mold 702, completing the pressing of the handle 3.

[0045] Furthermore, in order to reduce the pressure of the sliding cylinder 5031 on the support base 101, a pressure reducing ring 5033 is fixedly connected to the bottom of the sliding cylinder 5031, so that when the sliding cylinder 5031 contacts the support base 101, the pressure per unit area of ​​the support base 101 can be reduced, thereby extending the service life of the support base 101.

[0046] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
