Detailed implementation manners
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-6 。
[0026] The fixing device for the production of elevator lift accessories of the utility model includes a workbench 1. A first fixing unit 2 for fixing one end of the accessory is fixedly connected to the workbench 1. A second fixing unit 3 for fixing the other end of the accessory is slidably connected to the workbench 1. The first fixing unit 2 includes a first electric push rod 21 fixedly connected to the top of the workbench 1 and a first connecting rod 22 fixedly connected to the top of the first electric push rod 21. The second fixing unit 3 includes a sliding block 31 slidably arranged on the workbench 1, a second electric push rod 33 fixedly connected to the top of the sliding block 31, a second connecting rod 37 fixedly connected to the second electric push rod 33, and a first motor 35 fixedly connected to the second connecting rod 37. Clamping components 4 are arranged on the output ends of the first connecting rod 22 and the first motor 35.
[0027] That is to say, both ends of the accessory are clamped by two clamping components 4 respectively. When the length of the accessory to be fixed changes, the distance between the two clamping components 4 can be adjusted by changing the position of the second fixing unit 3.
[0028] Furthermore, the clamping component 4 includes a turntable 41 and two symmetrically arranged limiting plates 42 slidably connected to the turntable 41. A channel 421 for the sliding of the limiting plates 42 is opened on the turntable 41. Two threaded sleeves 44 are rotatably connected to the two limiting plates 42 respectively. A bidirectional screw rod 43 is commonly threadedly connected to the two threaded sleeves 44. The bidirectional screw rod 43 is rotatably connected to the turntable 41. The threads at both ends of the bidirectional screw rod 43 are arranged in reverse. The two ends of the bidirectional screw rod 43 are respectively connected to the two threaded sleeves 44. As Figure 4 shown, the limiting plate 42 can be set as an arc-shaped plate so that it can meet more clamping requirements. When specifically setting, a rubber gasket can be installed on the limiting plate 42 to improve the clamping effect of the limiting plate 42.
[0029] Even further, a bearing 45 is fixedly connected to the limiting plate 42. The outer ring of the bearing 45 is fixedly connected to the limiting plate 42, and the inner ring of the bearing 45 is fixedly connected to the threaded sleeve 44. Therefore, when the bidirectional screw rod 43 rotates, the two threaded sleeves 44 at both ends of it will rotate spirally along the screw rod. Also, because the threads at both ends of the bidirectional screw rod 43 are arranged in reverse, when the bidirectional screw rod 43 rotates, the two limiting plates 42 will approach or move away from each other.
[0030] In addition, one end of the screw rod is fixedly connected to a rotating rod 46, and a second motor 47 for driving the rotation of the rotating rod 46 is fixedly connected to the turntable 41.
[0031] Secondly, the bottom of the sliding block 31 is arranged in an inverted T shape, and a sliding groove 32 adapted to the size of the sliding block 31 is opened on the workbench 1. A third electric push rod 34 is fixedly connected to the bottom of the workbench 1, and the extending end of the third electric push rod 34 is fixedly connected to the sliding block 31.
[0032] Again, the first connecting rod 22 is rotatably connected to the clamping member 4, the output end of the first motor 35 is fixedly connected to the other clamping member 4, and a telescopic rod 36 is connected between the two clamping members 4. That is to say, when the clamping member 4 on the second fixing unit 3 rotates with the first motor 35, it will drive the clamping member 4 on the first fixing unit 2 to rotate.
[0033] It should be noted that when using this device, when it is necessary to adjust the processing height of the fitting, directly adjust the heights of the first electric push rod 21 and the second electric push rod 33. When it is necessary to fix fittings of different lengths, directly adjust the third electric push rod 34 to adjust the distance between the two clamping members 4. When it is necessary to fix fittings of different diameters or thicknesses, start the second motor 47 to rotate the bidirectional screw 43 to make the two limiting plates 42 approach or move away from each other. When it is necessary to adjust the processing angle during processing, directly start the first motor 35 to rotate the clamping member 4.
[0034] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
