[0035] Embodiment 1:
[0036] Please refer to Figure 1-5 The present embodiment provides a handle double-sided clamping mechanism, including a mounting base 10, and a driving member 20, an angle push block 30, a first clamping block 40 and a second clamping block 50 mounted on the mounting base 10.
[0037] The mounting base 10 mainly plays a supporting role and provides a mounting base for each component. For ease of understanding, it is assumed that the mounting base 10 has a length direction, a width direction and a height direction corresponding to an orthogonal coordinate system.
[0038] The driving member 20 is used to provide a power source for the mechanism to clamp the handle end. The driving member 20 has a fixed end and a telescopic end. The fixed end of the driving member 20 is fixed to the mounting base 10 through a vertical plate, and the telescopic end is used to connect with the angle push block 30, thereby driving the angle push block 30 to move back and forth in the length direction of the mounting base 10.
[0039] The two ends of the angle push block 30 respectively form a pushing end and a clamping end, the pushing end is used to connect with the telescopic end of the driving member 20, the clamping end is formed with a clamping groove, the bottom of the clamping groove forms a pushing surface 31, and the two sides respectively form a first inclined surface 32 and a second inclined surface 33; the pushing surface 31 is used to fix the handle end surface.
[0040] The bottoms of the first clamping block 40 and the second clamping block 50 are both slidably connected to the mounting seat 10 , so that the first clamping block 40 and the second clamping block 50 can move relative to the mounting seat 10 in the width direction thereof.
[0041] A first mating surface 41 and a first clamping surface 42 are respectively formed on opposite sides of the first clamping block 40, and the first mating surface 41 is slidably connected to the first inclined surface 32; the first mating surface 41 can be an inclined surface corresponding to the first inclined surface 32, and the two are in surface contact to improve the force transmission efficiency; through the cooperation between the first mating surface 41 and the first inclined surface 32, the first clamping block 40 is driven to move in the width direction of the mounting seat 10, so that the first clamping surface 42 is close to or away from the handle.
[0042] The second mating surface 51 and the second clamping surface 52 are respectively formed on the opposite sides of the second clamping block 50, and the second mating surface 51 is slidably connected with the second inclined surface 33; the first mating surface 41 can be an inclined surface corresponding to the first inclined surface 32, and the two are in surface contact to improve the force transmission efficiency; through the cooperation between the first mating surface 41 and the first inclined surface 32, the first clamping block 40 is driven to move in the width direction of the mounting seat 10, so that the first clamping surface 42 is close to or away from the handle.
[0043] The first clamping surface 42 and the second clamping surface 52 are disposed opposite to each other so as to clamp two opposite sides of the handle.
[0044] When in use, place the end of the handle close to the clamping groove, provide power through the driving member 20, and the telescopic end pushes the angle push block 30 to extend, so that the pushing surface 31 is close to the handle to position the end face of the handle. At the same time, under the push of the angle push block 30, the first inclined surface 32 cooperates with the first matching surface 41 to convert the movement of the angle push block 30 along the length direction of the mounting seat 10 into the movement of the first clamping block 40 in the width direction of the mounting seat 10. Similarly, through the cooperation of the second inclined surface 33 and the second matching surface 51, the movement of the angle push block 30 along the length direction of the mounting seat 10 is converted into the movement of the second clamping block 50 in the width direction of the mounting seat 10, so that the first clamping surface 42 and the second clamping surface 52 are close to each other at the same time, clamping both sides of the handle to achieve clamping and fixing of the handle. The double-sided clamping mechanism of the handle of the present embodiment has a simple structure. It can realize clamping of the handle end in three directions by driving with one power source, thus saving power. By setting the angle push block 30, the first inclined surface 32 cooperates with the first matching surface 41, and the second inclined surface 33 cooperates with the second matching surface 51, the direction of the object can be changed without changing the shape of the object. The first clamping block 40 and the second clamping block 50 can be moved at the same time, and the same clamping force can be applied to the opposite sides of the handle to ensure that the left and right sides of the handle are in a straight line, and will not be deflected due to inconsistent force on the two sides. The clamping effect is stable and reliable.
[0045] Specifically, the mounting seat 10 is provided with a slide rail 11, which is arranged along the width direction of the mounting seat 10, that is, the direction of the slide rail 11 is perpendicular to the telescopic direction of the driving member 20; the first clamping block 40 and the second clamping block 50 are respectively formed with a first slide groove at the bottom; the first clamping block 40, the second clamping block 50 and the mounting seat 10 are slidably connected through the cooperation of the first slide groove and the slide rail 11. By providing the slide rail 11 and cooperating with the first slide groove, the movement of the first clamping block 40 and the second clamping block 50 on the mounting seat 10 is guided, and the clamping stability of the first clamping surface 42 and the second clamping surface 52 on both sides of the handle is improved.
[0046] The driving member 20 clamps the handle by telescopically pushing the push block 30, which can be realized by telescopic members such as rack gears and screw mechanisms. The driving member 20 of this embodiment is a telescopic cylinder structure, which can realize stepless control, and is conducive to eliminating transmission clearance, and is more suitable for fixing the handle. The telescopic end of the cylinder in this embodiment has a central axis; the angle formed by the first inclined surface 32 and the central axis is a, and the angle formed by the second inclined surface 33 and the central axis is b, and the angle a is equal to the angle b. That is, the first inclined surface 32 and the second inclined surface 33 are symmetrically arranged on both sides of the central axis. Thereby, the first clamping block 40 and the second clamping block 50 at both ends move synchronously under the drive of the first inclined surface 32 and the second inclined surface 33, and apply the same clamping force to both sides of the handle.
[0047] Specifically, the angles of angle a and angle b are preferably 5°-30°, which is more conducive to the conversion of motion between the angle push block 30 and the first clamping block 40 and the second clamping block 50. In this embodiment, the angles a and b are both 13°.
[0048] The push surface 31 of this embodiment is also provided with a connecting block 60, which is slidably connected with the angle push block 30; specifically, a pull groove 34 is provided on the angle push block 30, and the direction of the pull groove 34 is consistent with the push direction of the angle push block 30, and a pin is provided at the corresponding position of the connecting block 60, and the connecting block 60 is slidably connected with the angle push block 30 through the cooperation of the pin and the pull groove 34, so that the connecting block 60 can be close to or away from the push surface 31. A first countersunk hole 311 is provided on the push surface 31, and a second countersunk hole is provided on the side of the connecting block 60 close to the push surface 31; a first elastic member is provided between the connecting block 60 and the angle push block 30, one end of the first elastic member is provided in the first countersunk hole 311, and abuts against the connecting block 60, and the other end is provided in the second countersunk hole, and abuts against the angle push block 30; the first elastic member provides an elastic force for the connecting block 60 to move away from the angle push block 30. The first elastic member pushes the connecting block 60 to bring the ends of the handle closer together, providing a tighter connection for the handle end faces, eliminating the connection gap, and converting the rigid connection for the handle end faces into a flexible connection, which can avoid damage to the handle due to excessive squeezing force during the advancement of the angle push block 30 and improve the yield rate.
[0049] Furthermore, a slider 71 is provided on one side of the clamping block 70, and the slider 71 is slidably connected in the second slide groove 61, so that the clamping block 70 can move relative to the connecting block 60 in the height direction of the mounting seat 10; a clamping surface is provided on the side of the clamping block 70 away from the connecting block 60, and the clamping surface is adapted to the end face of the handle. By providing a clamping surface adapted to the end face of the handle, the contact area between the clamping mechanism and the handle is further increased, and the clamping stability is improved; the clamping block 70 is slidably connected to the connecting block 60 in the second slide groove 61 through the slider 71, so that the clamping block 70 can be adjusted in the height direction of the mounting seat 10 to adapt to handles of different heights, which is more practical. When processing handles of different models, it is only necessary to replace the adapted clamping block 70 to complete the replacement of the processing production line, which is convenient for disassembly and mold replacement and has stronger applicability.
[0050] In this embodiment, a limit block 80 is provided on the slide rail 11, and the two opposite sides of the limit block 80 form a first limit surface and a second limit surface respectively. When the first clamping block 40 and the second clamping block 50 are close to each other to the limit position, the first limit surface abuts against the first mating surface 41, and the second limit surface abuts against the second mating surface 51. The limit block 80 is provided to prevent excessive displacement of the first clamping block 40 and the second clamping block 50, and the limit block 80 can play a role in centering the first clamping block 40 and the second clamping block 50. A positioning surface for carrying a handle can also be formed on the top of the limit block 80. When in use, the end of the handle is placed on the positioning surface, and then clamped by the driving member 20, thereby improving the clamping success rate.
[0051] A second elastic member is provided between the first limiting surface and the first mating surface 41 of this embodiment, one end of the second elastic member abuts against the first limiting surface, and the other end abuts against the first mating surface 41, and the second elastic member provides an elastic force for the first clamping block 40 to move away from the limiting block 80;
[0052] A third elastic member is arranged between the second limiting surface and the second mating surface 51. One end of the third elastic member abuts against the second limiting surface, and the other end abuts against the second mating surface 51. The third elastic member provides an elastic force for the second clamping block 50 to move away from the limiting block 80.
[0053] The first elastic member, the second elastic member and the third elastic member of the present embodiment can all be springs. By utilizing the elastic deformation of the spring to automatically adjust the deformation deviation of the clamping block 70, the first clamping block 40 and the second clamping block 50, the clamping block 70, the first clamping block 40 and the second clamping block 50 can clamp three positions at the same time, which can effectively avoid the free gap between the clamping block 70, the first clamping block 40, the second clamping block 50 and the handle due to processing errors or assembly angle deviations, thereby affecting the clamping strength; secondly, the provision of the first elastic member, the second elastic member and the third elastic member can help the clamping block 70, the first clamping block 40 and the second clamping block 50 to quickly reset after releasing the handle, thereby avoiding the first clamping block 40 and the second clamping block 50 from being unable to open after clamping, and utilizing the elastic force of the spring to bounce them open. The telescopic cylinder drives the angle push block 30 forward, and the first clamping block 40 and the second clamping block 50 move closer to each other, squeezing the first elastic member and the second elastic member, thereby clamping the handle; when the telescopic cylinder retracts, the first clamping block 40 and the second clamping block 50 have no force to squeeze the first elastic member and the second elastic member, and the first clamping block 40 and the second clamping block 50 are quickly rebounded to their original positions under the action of their elastic force, thereby improving production efficiency.
[0054] Embodiment 2:

It includes a base 90 and a handle double-sided clamping mechanism fixed at both ends of the base 90. The two handle double-sided clamping mechanisms are arranged opposite to each other and are used to fix the two opposite ends of the handle. The mounting plate of the handle double-sided clamping mechanism at one end is fixedly connected to the base 90 through a progress piece. The mounting plate of the handle double-sided clamping mechanism at the other end is slidably connected to the base 90, so that the two relatively arranged handle double-sided clamping mechanisms can move closer to or farther away from each other. A latching tooth is provided at the bottom of the mounting plate, and a corresponding rack is provided at the corresponding position of the base 90. The relative position of the handle double-sided clamping mechanism and the base 90 is locked by the cooperation of the latching tooth and the latching strip.
[0056] The puller assembly structure of this embodiment adopts an automatic clamping form, with a fixed end and a movable end: the welding operation is completed on these two areas. The puller assembly structure is simple and stable, can realize the rapid clamping and positioning of the handle, and can be adjusted according to different lengths of the handle, and is convenient for disassembly and mold replacement. A rack is used to connect the center, which further maintains the stability of the welded parts and can effectively maintain the integrity of the welded parts, thereby improving and reducing the cost of subsequent processing.
