Description

Technical Field

[0001] The utility model relates to a turning tool with a flange part, belonging to the technical field of workpiece clamping devices. Background Art

[0002] High-voltage switches are large-scale assembly equipment, which involve many parts and require high assembly precision. In the process of installing the parts into the shell, it may be necessary to install and measure the shell in multiple positions. In the actual operation, the staff needs to flip the shell many times, but due to the large size, high weight, and irregular shape of the shell, the staff's assembly efficiency is low and the assembly precision cannot be guaranteed.

[0003] Chinese invention patent CN105390325A, filed on November 20, 2015, discloses a shielding installation device for a high-voltage switch bushing, which includes two brackets arranged opposite to each other and extending in the up-down direction. The upper part of each bracket is rotatably equipped with a flip body for driving the shielding member to flip forward and backward, and the flip body is provided with a fixing structure for fixing the shielding flange of the shielding member. The flip body includes a support plate for fixing the shielding member and a rotating plate that rotates with the bracket. The bracket is provided with a first limit hole and a second limit hole for keeping the high-voltage switch bushing in a vertical and horizontal state respectively, and the rotating plate is provided with a matching limit hole that can correspond to the first limit hole or the second limit hole when the high-voltage switch bushing is rotated to a vertical or horizontal state. When the high-voltage switch bushing needs to be kept in a vertical state, the limit is achieved by passing the limit pin through the first limit hole and the matching limit hole; when the high-voltage switch bushing needs to be kept in a horizontal state, the limit is achieved by passing the limit pin through the second limit hole and the matching limit.

[0004] The above device can realize the front and back flipping of the shielding part and can limit and fix it in the vertical and horizontal states, which reduces the labor intensity of workers to a certain extent. However, the device can only realize the limit and fixation of the shielding part in the vertical and horizontal states, and workers cannot adjust the angle of the shielding part as needed. In addition, the device needs to rely on manual operation to flip. During the flipping process, the shielding part is in an unlocked state. Due to the weight and size of the shielding part, workers cannot flip the shielding part alone, align the limit hole, and operate the limit pin shaft to pass through the limit hole while maintaining the alignment of the limit hole. There are still problems such as inconvenient operation, high labor intensity of workers, and low assembly efficiency. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model provides a technical solution of a turning tool with a flange part:

[0008] Furthermore, the fixing frame is fixedly arranged on the vertical frame, a bearing seat is installed on the fixing frame, and the power input shaft is rotatably installed on the bearing seat.

[0009] Furthermore, the fixed frame includes a horizontally arranged first mounting plate, the end of the first mounting plate is fixedly connected to the side wall of the vertical frame, and the driving mechanism is fixedly mounted on the first mounting plate; two vertically and parallelly arranged support plates are fixed on the top surface of the first mounting plate close to one end of the side wall of the vertical frame, and the fixed frame also includes a second mounting plate fixed on the top of the two support plates, and the bearing seat is fixedly mounted on the second mounting plate.

[0010] Furthermore, a reinforcing plate is fixedly connected between the bottom surface of the first mounting plate and the side wall of the stand.

[0013] Furthermore, the base includes two longitudinal beams arranged in parallel and a transverse beam connected between the middle parts of the two longitudinal beams, and a vertical frame is fixedly arranged on each longitudinal beam.

The worm gear driving mechanism can realize the self-locking of parts at any angle at any time. Workers can adjust the angle of parts according to the needs of the site without having to operate the locking structure specifically, which greatly improves the efficiency of parts assembly.

DETAILED DESCRIPTION

[0027] The existing flipping tooling relies on manual operation to flip, and during the flipping process to the target position after the limit of the first limit structure is released, the shielding part is in an unlocked state. Due to the weight and size of the shielding part, workers cannot flip the shielding part alone, align the limit holes, and operate the limit pin to pass through the limit holes while maintaining the alignment of the limit holes. There are still problems such as inconvenient operation, high labor intensity for workers, and low assembly efficiency. The utility model adopts a worm gear drive mechanism to drive the rotation of the flanged parts, which can realize self-locking of the parts at any angle at any time. Workers can adjust the angle of the parts according to on-site needs without the need to specially operate the locking structure. That is, workers only need to operate the driving mechanism with one hand to make the parts rotate freely at any angle, which effectively reduces the labor intensity of workers and greatly improves the parts assembly efficiency.

[0028] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0029] The specific embodiment of the turning tool with flange parts provided by the utility model is as follows:

[0030] like Figure 1 As shown, the turning tool with flange parts includes a base 9, two upright frames 1 arranged opposite to each other on the base 9, and a turning body 2 rotatably assembled on the top of the two upright frames 1. The turning body 2 includes a connecting structure that can be fixedly connected to the flange on the housing 6 and a rotating shaft rotatably assembled with the support frame 1 through a bearing seat 8. Specifically, the connecting structure includes the following: Figure 3 The fixing plate 21 shown in the figure has mounting holes corresponding to the flange holes of the parts. When in use, bolts are passed through the flange holes of the housing 6 and the mounting holes on the fixing plate 21 and connected with nuts to fix the parts to the flip body 2. In this embodiment, the number of mounting holes on each fixing plate 21 is three. Of course, depending on the specific situation, the number of mounting holes can be set to two or four. In actual use, fixed connection can be achieved through some or all of them as needed.

[0031] In other embodiments, the mounting hole may also be a threaded hole, and a screw is passed through the flange hole of the housing 6 and threadedly connected with the threaded hole on the fixing plate to fix the housing 6. In other embodiments, the connection structure may not be a fixing plate with mounting holes, but a clamping plate capable of clamping the flange structure of the part, and the clamping plate has a fixing plate and a movable plate respectively fitted with the upper and lower sides of the flange of the part, and the movable plate can be moved away from or close to the fixing plate to avoid and fix the flanged part.

[0032] The two support frames 1 respectively include two parallel and spaced columns, and the rotating shaft on the flip body 2 passes through the gap between the corresponding two columns. When installing or disassembling the tooling, the flip body 2, the bearing seat and the driving structure can be fixedly connected first, and then the whole is installed on the frame. The flip tooling with flange parts also includes a worm gear drive mechanism that is transmission-connected to the rotating shaft of the flip body 2, and the rotating shafts in the two flip bodies 2 that are transmission-connected to the driving mechanism constitute a power input shaft 31. In this embodiment, the driving mechanism is a commercially available worm gear reducer 5, which has a power input end and an output end for transmission connection with the rotating shaft. The worm gear reducer has the advantages of accurate angle conversion and labor saving, and the structure is small and efficient and can be directly assembled on the support frame 1 to facilitate the flexible movement of the flip tooling.

[0033] like Figure 2 As shown, the base 9 includes two longitudinal beams 91 arranged in parallel and spaced apart and a cross beam 92 connected between the middle parts of the two longitudinal beams. A support frame 1 is fixedly arranged on each longitudinal beam, and only one cross beam 92 is arranged in the middle of the two parallel longitudinal beams 91, which has a simple and compact structure. The two support frames 1 are welded and fixed on the two longitudinal beams 91 respectively, and the distance between them constitutes a flipping space for accommodating the shell 6. In order to facilitate the position movement of the flip tool, casters 7 are arranged on the lower surface of the two longitudinal beams 91, and in order to maintain the stability of the flip tool structure, there are four casters 7 and they are arranged at the two ends of the two longitudinal beams 91 respectively.

[0034] In order to ensure the stable and easy installation of the driving mechanism, a fixing frame for supporting and fixing the driving mechanism is preset on one side of the support frame 1 close to the driving mechanism in this embodiment. The fixing frame includes a horizontally arranged first mounting plate 11 for fixing and installing the worm gear driving mechanism, and the end of the first mounting plate 11 is welded and fixed to the side wall of the frame. Two vertical and parallel supporting plates 13 are fixed on the top surface of the first mounting plate 11 close to the side wall of the frame, and the fixing frame also includes a second mounting plate 12 fixed on the top of the two supporting plates, and the bearing seat 8 of the rotating shaft is fixedly mounted on the second mounting plate 12. In order to further stably support the driving mechanism, a reinforcing plate 14 is fixedly connected between the bottom surface of the first mounting plate 11 and the side wall of the frame 1. Furthermore, the two supporting plates 13 and the second mounting plate 12 are welded and fixed to the side wall of the frame 1 to achieve stable support for the bearing seat 8.

[0035] Of course, in the case of stable support, the second mounting plate 12 may not be welded to the stand 1, but may be supported and fixed only by the two support plates 13. Similarly, the two support plates 13 may also be fixedly connected to the first mounting plate 11 only, without being welded to the stand 1. In addition, the reinforcing plate 14 may not be provided.

[0036] like Figure 1 , 3-6, each fixing plate 21 is rotatably mounted on the corresponding support frame 1 through a rotating shaft. In this embodiment, one of the rotating shafts constitutes a power input shaft 31 that is transmission-connected to the driving mechanism, and the other rotating shaft constitutes a driven shaft 32. Relative to the driven shaft 32, the power input shaft 31 has an extension section 311 for transmission connection with the output end of the worm gear reducer 5. The extension section 311 and the output end of the worm gear reducer 5 are transmission-connected through a coupling sleeve 4. Specifically, as shown in FIG. Figure 4 , 6 As shown in FIG. 7 , an outer keyway 312 is provided on the outer circumference of the extension section 311 and one end of the output shaft of the worm gear reducer 5, and an inner keyway 41 is provided on the inner wall of the corresponding coupling sleeve 4. During assembly, the flat key 10 is embedded in the inner and outer keyways to achieve power transmission between the output end of the drive mechanism and the power input shaft 31. If the output end of the drive mechanism has a flat key structure, the flat key can be directly embedded in the preset keyway on the coupling sleeve. Similarly, in order to facilitate power input, as shown in FIG. Figure 8 As shown, an adapter 51 is sleeved on the input end of the worm gear reducer 5, one end of the adapter 51 is provided with an inner anti-rotation hole that cooperates with the input end of the driving mechanism, and the other end is an outer hexagonal structure 511 with an outer anti-rotation surface. The turning tool in this embodiment also includes an operating hand wheel (not shown in the figure), and the output end of the operating hand wheel has an inner hexagonal structure that cooperates with the outer cubic structure 511 to prevent rotation.

[0037] Of course, in other embodiments, the turning tool may not include an operating hand wheel, but a self-made crank that matches the shape of the outer hexagonal structure. Of course, in order to further save manpower, the outer hexagonal structure can be directly connected to the motor.

[0038] In other embodiments, instead of using a commercially available worm gear reducer, a self-made worm gear drive mechanism may be used. For example, the output shaft of the self-made worm gear drive mechanism has a certain length and can be directly connected to the flip body through the bearing seat. In this case, no additional transmission connection structure is required between the flip body and the drive mechanism. Similarly, the end of the input shaft can be directly processed into an external hexagonal structure, and an operating handwheel with an internal hexagonal structure can be directly installed when in use. In this case, no adapter is required.

[0039] In other embodiments, if the working space allows, the base may not be composed of two longitudinal beams and one transverse beam, but may be a frame structure surrounded by two transverse beams and two longitudinal beams.

[0040] In other embodiments, the stand may also be an integrated structure, and an avoidance hole needs to be opened on it to allow the shaft to pass through. In this case, the shaft needs to pass through the avoidance hole first and then be connected to other structures.

[0041] In other embodiments, the fixing frame may not be arranged on the stand, but directly on the base, and it is only necessary to ensure that the driving mechanism and the bearing seat installed thereon match the height of the flip body. Similarly, in other embodiments, the bearing seat may be fixed separately from the driving mechanism, and respectively welded to the stand or the base.
