Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a servo clamp for producing a steel cage. Background Art

[0002] The structure of the shear wall cage formwork prefabricated parts is divided into steel cage and cement formwork. The formwork cement board adopts reinforced concrete thin plate with the same strength grade as the structure. It will not be removed after the construction is completed and will become one with the main structure. Therefore, it has the outstanding characteristics of no building formwork and no construction waste. The shear wall cage formwork prefabricated parts need to manufacture a large number of steel cages in the production process. The overall mass of the steel cage is large. In order to reduce the work intensity of the workers, multiple handling and turning equipment will be arranged on the production line. These devices are generally equipped with structures that can clamp the steel cage, and the clamping is on the thick side wall of the steel cage. This part of the structure is more resistant to pressure. The part of the clamping structure that is in direct contact with the steel cage is generally a square rod. The square rod is fixedly connected to the clamping structure. However, when clamping different steel cage products, it may be necessary to replace square rods of different sizes. In addition, the square rod is also a consumable part. Therefore, the square rod is detachably fixed to the clamping structure, and is usually assembled by bolt tightening. The longer the square rod is, the more bolts are needed for positioning, and the more time is required for disassembly and installation. In order to reduce the working hours consumed in replacing the square rod, it is necessary to develop a clamp that can automatically open and close the square rod. Summary of the invention

[0003] The utility model provides a servo clamp for producing a steel cage, which solves the problem in the prior art that the disassembly and assembly of a clamping structure and a square rod are complicated and time-consuming.

[0004] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a servo clamp for the production of steel cages, characterized in that: it includes a mounting seat, on which a first rotating shaft and a second rotating shaft that are parallel and spaced from each other are rotatably connected, and the two rotating shafts are axially fixed relative to the mounting seat, and the mounting seat is provided with a servo motor that is transmission-connected to any rotating shaft, a first gear and a first threaded section are coaxially provided on the first rotating shaft, a second gear and a second threaded section that are meshed with the first gear are coaxially provided on the second rotating shaft, a first slider is screwed on the first threaded section, and a second slider is screwed on the second threaded section, and a limiting portion that can limit the two sliders to follow the rotation is provided on the mounting seat, a first clamping plate is fixed on the first slider, a second clamping plate is fixed on the second slider, and a clamping area is formed between the two clamping plates.

[0005] The working principle of the utility model is as follows: since the first rotating shaft and the second rotating shaft are connected by two meshing gears, the two rotating shafts can be driven to rotate synchronously in the opposite direction after the servo motor rotates. Since the two rotating shafts are provided with thread segments with the same direction, the first slider and the second slider cannot rotate under the constraint of the limiter, and thus displacement will be generated with the rotation of the thread segments. The rotation directions of the first thread segment and the second thread segment are opposite, and the movement directions of the two sliders are also opposite, so that the two clamping plates can produce opposite movement effects. Therefore, the utility model can realize the opening and closing action of the two clamping plates only by controlling the forward and reverse rotation of the servo motor, and the clamping area between the two clamping plates can be used to clamp and fix the square rod. When the two clamping plates are clamped with the square rod, the reaction force generated by the clamping will be detected by the torque detection function of the servo motor, thereby realizing automatic shutdown.

[0006] Furthermore, the mounting seat is also provided with a sliding seat, the sliding seat is provided with a sliding groove, and the sliding seat is also provided with a fastening bolt that can penetrate into the sliding groove. In this way, the utility model can be slidably installed on a slide rail that matches the size of its slide groove. When the fastening bolt is loosened, the utility model can freely translate and adjust the position relative to the slide rail. After the position is adjusted, the fastening bolt is tightened, so that the utility model is fixed relative to the slide rail.

[0007] Therefore, compared with the prior art, the utility model has the following characteristics: 1. By controlling the forward and reverse rotation of the servo motor, the two clamping plates can be opened and closed autonomously, and the clamping area between the two clamping plates can be used to clamp and fix the square rod. When the two clamping plates are clamped with the square rod, the reaction force generated by the clamping will be detected by the torque detection function of the servo motor, thereby achieving automatic shutdown; 2. The utility model can be slidably installed on a slide rail that matches the size of its slide groove, so as to facilitate free adjustment of the installation position.

[0011] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0012] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0013] Example 1: See Figure 1 , Figure 2 and Figure 3 A servo clamp for producing steel cages includes a mounting seat 10, on which a first rotating shaft 20 and a second rotating shaft 30 which are parallel and spaced from each other are rotatably connected, and the two rotating shafts are axially fixed relative to the mounting seat, and a servo motor 40 which is transmission-connected to the first rotating shaft is provided on the mounting seat, a first gear 21 and a first threaded section 22 are coaxially provided on the first rotating shaft, a second gear 31 and a second threaded section 32 which are meshed with the first gear are coaxially provided on the second rotating shaft, a first slider 23 is screwed on the first threaded section, and a second slider 33 is screwed on the second threaded section, and a limiting portion 101 which can limit the two sliders from following rotation is provided on the mounting seat, and the limiting portion is slidably fitted with the two sliders, a first clamping piece 24 is fixed on the first slider, and a second clamping piece 34 is fixed on the second slider, and a clamping area is formed between the two clamping pieces.

[0014] See Figure 2 A transmission section 201 is extended to one end of the first rotating shaft, a reducer 41 is connected to the output end of the servo motor, and a coupling 42 is connected between the output end of the reducer and the transmission section.

[0015] See Figure 2 Two parallel and spaced clamping plates 11 are fixed on the mounting seat, the first rotating shaft and the second rotating shaft are rotatably connected to the two clamping plates, and two bearing mounting seats 12 are provided on the inner side surfaces of the two clamping plates, and tapered roller bearings 13 sleeved with the two rotating shafts are provided in the bearing mounting seats. When the two clamping plates are clamped, the reaction force generated by the clamping will be transmitted to the two rotating shafts, so a large extrusion force will be generated between the rotating shaft and the clamping plates, and the tapered roller bearings can not only reduce the friction of the circumferential rotation of the rotating shaft, but also have a good thrust effect.

[0016] See Figure 1The mounting seat is also provided with a sliding seat 14, a sliding groove 15, and a fastening bolt 16 that can penetrate into the sliding groove. In this way, the embodiment can be slidably mounted on a slide rail that matches the size of its slide groove. When the fastening bolt is loosened, the embodiment can freely translate and adjust the position relative to the slide rail. After the position is adjusted, the fastening bolt is tightened, so that the embodiment is fixed relative to the slide rail.

[0017] The working principle of this embodiment is as follows: since the first rotating shaft and the second rotating shaft are connected by two meshing gears, the servo motor can drive the two rotating shafts to rotate synchronously in the opposite direction after rotating. Since the two rotating shafts are provided with thread segments with the same direction, the first slider and the second slider cannot rotate under the constraint of the limiter, and thus displacement will be generated with the rotation of the thread segments. The rotation directions of the first thread segment and the second thread segment are opposite, and the movement directions of the two sliders are also opposite, so that the two clamping plates can produce opposite movement effects. Therefore, this embodiment can realize the opening and closing action of the two clamping plates only by controlling the forward and reverse rotation of the servo motor, and the clamping area between the two clamping plates can be used to clamp and fix the square rod. When the two clamping plates are clamped with the square rod, the reaction force generated by the clamping will be detected by the torque detection function of the servo motor, thereby realizing automatic shutdown.

[0018] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
