Detailed Description

As shown in fig. 1, the screw compressor 90 includes a head 91 for compressing air to form compressed air and a motor 92 connected to one end of the head 91 for driving the head 91 to operate to perform the air compression process, specifically, the head 91 is provided with an outwardly protruding rotor shaft 911, the motor 92 is provided with a mounting hole (view reason is not shown) toward the side of the head 91, the rotor shaft 911 is provided in the mounting hole by key connection when the head 91 and the motor 92 are assembled, and the head 91 and the housing of the motor 92 are connected by bolts to form a unit.

As is well known, the handpiece 91 and the motor 92 are mostly made of metal, so that they are very heavy, and particularly, when assembled, they are very inconvenient to carry, which makes the assembly of the two difficult. And the installation clearance between the rotor shaft 911 and the installation hole is small, thereby further increasing the installation difficulty.

In order to solve the above-mentioned problem, the present application provides a turning device for assembling a compressor head and a motor, by firstly installing the head 91 into the turning device along the horizontal direction and clamping, fixing the head 91 in the turning device, then turning the head 91 by 90 degrees, making the rotor shaft 911 face upwards, thereby enabling a worker to clearly observe the installation position, and then installing the motor 92 onto the head 91 downwards from above the head 91, since the motor 91 is relatively light, the circumferential direction and the horizontal direction are conveniently adjusted by rotating or translating, which is beneficial to the installation. After the installation is completed, the turnover device reversely turns over to horizontally arrange the compressor, so that a worker can conveniently take out the compressor.

Fig. 2 and 3 show perspective views of a turnover device, which includes a bracket 10, a base plate 11 horizontally disposed is fixedly disposed at the middle of the bracket 10, a rotating shaft 20 extending in the front-rear direction is rotatably disposed on the base plate 11 through a bearing 12, and a turnover plate 30 is fixedly disposed at the front end of the rotating shaft 20, whereby the turnover plate 30 can be turned in a vertical plane with the rotating shaft 20 as an axis. The turnover plate has a first position and a second position, wherein the first position and the second position are separated by 90 degrees, and when the turnover plate 30 is in the first position (see fig. 2), the feeding action of the machine head 91 or the discharging action of the compressor 90 is performed; when the flipping plate 30 is in the second position (see fig. 6), the mounting action of the motor 92 is performed.

The structure of the flipping unit will be further described below in terms of the flipping panel 30 being in the first position, with reference to fig. 2, the front side of the flipping panel 30 generally facing the worker, the front side of the flipping panel 30 being provided with a head mount 40 for supporting and positioning the head 91 and a head clamping assembly 50 for clamping the head 91 to the head mount 40. Specifically, the head mount 40 includes a foot support plate 41 provided in a horizontal direction and an end positioning plate 42 perpendicular to the foot support plate 41 (provided in a vertical direction), and in this embodiment, the foot support plate 41 is provided in two and in a front-rear direction, the lower portions of the two foot support plates 41 are provided together on a horizontal connection plate 43, and the foot support plate 41 is fixed to the roll-over plate 30 by the horizontal connection plate 43. By providing the foot support plate 41 such that a height difference is formed between the foot support plate 41 and the horizontal connection plate 43 to accommodate a portion of the head 91 where the bottom is projected downward, the head 91 is smoothly placed on the head mount 40. In addition, the foot support plate 41 and the end positioning plate 42 are preferably spaced apart to accommodate the protruding portion of the hand piece 91.

The head clamping assembly 50 is disposed on the opposite side of the foot support plate 41, and is shown disposed above the foot support plate 41 in fig. 2, so that a mounting space for mounting the head 91 is formed between the head clamping assembly 50 and the foot support plate 41, and an output end (hereinafter, a clamping plate 54) of the head clamping assembly 50 is movable toward the position of the foot support plate 41, so that the head 91 can be fixed in the head mounting frame 40 when the output end thereof is clamped to the head 91 (see fig. 4). Note that when the head 91 is fixed in the installation space, the right end of the head 91 is completely exposed in the installation space to facilitate the installation of the subsequent motor 92.

In addition, it is noted that if the head clamping assembly 50 is always located above the installation space, the upper side of the installation space is closed, and the head 91 can only enter the installation space from the front side or the right side, which is disadvantageous for a worker to put the head 91 into the installation space, and particularly, the head 91 has a considerable weight in the present embodiment, and places a high requirement on the physical strength of the worker. For this reason, the head clamping assembly 50 is preferably provided to be able to enter or leave the installation space, for example, in this embodiment, the head clamping assembly 50 is rotatable about one end thereof to enter or leave the installation space, in which case, when the head 91 is required to be installed, the head clamping assembly 50 can be rotated out of the installation space so that an open entrance is formed above the installation space, which significantly enlarges the position where the head 91 can enter the installation space to facilitate placement of the head 91.

The use process of the turnover device is as follows: the turnover plate 30 is turned to a first position, that is, the foot support plate 41 is in a horizontal plane, and then the head clamping assembly 50 is rotated outwards to be separated from the upper part of the installation space (see fig. 2), the upper part of the head positioning assembly 40 is completely exposed, a worker places the head 91 on the foot support plate 41, and the foot at the bottom of the head 91 is connected to the foot support plate 41, so that the head 91 is laid on the head mounting frame 40, and then the horizontal position of the head 91 is adjusted, so that the end (also called the tail end) of the head 91 far away from the rotor shaft 911 is abutted against the end positioning plate 42, thereby realizing the positioning of the head 91 (see fig. 4); then the head clamping assembly 50 is rotated back to the upper part of the installation space and fixed, and then the output end of the head clamping assembly 50 moves towards the installation space and abuts against the top of the head 91, so that the head 91 is clamped down on the foot supporting plate 41, and clamping of the head 91 is realized at this time; the flipping plate 30 is flipped by 90 degrees counterclockwise to be in the second position (see fig. 6), at this time, the rotor shaft 911 of the head 91 is disposed toward the upper side, and the tail end of the head 91 is supported by the lower end positioning plate 42, thereby ensuring that the head 91 is fixed in the installation space without movement; at this time, the worker carries the motor 92 above the head 91 and adjusts the position of the motor 92 so as to be mounted on the head 91; after installation, the flipping panel 30 is flipped 90 degrees in the opposite direction and returned to the first position, after which the head clamping assembly 50 is rotated away from the installation space, and the worker removes the assembled compressor from the installation space.

As can be seen from the above, the flipping plate 30 has a first position in which positioning and clamping of the head 91 are facilitated, and a second position in which mounting of the motor 92 is facilitated, so that the relative positions of the head 91 and the motor 92 can be controlled more flexibly than in the prior art in which mounting of the head 91 and the motor 92 is implemented on a horizontal table, thereby improving the accuracy of mounting and facilitating assembly operations by workers. Further, it is noted that the head clamping assembly 50 can enter or leave the installation space so that the upper portion of the installation space has a very wide space when the head 91 is installed, thereby facilitating the placement of the head 91 into the installation space by a worker without the need for installation from a specific angle, simplifying the installation step.

Further, in order to realize the rotatable arrangement of the head clamping assembly 50 described above, as shown in fig. 2 and 4, the head clamping assembly 50 includes a swing arm 51, the swing arm 51 is oppositely arranged above the foot supporting plate 41, one end of the swing arm 51 is provided with a connecting shaft 52, the other end is provided with a first locking member 53, in this embodiment, the connecting shaft 52 is arranged at the front end of the end positioning plate 42, and the axial direction of the connecting shaft 52 is perpendicular to the plane of the foot supporting plate, and the swing arm 51 is rotated about the connecting shaft 52 so as to swing above the installation space to enter or leave the installation space. The second locking part 31 matched with the first locking part 53 is arranged on the turnover plate 30, the first locking part 53 is connected with the second locking part 31 to form a locking structure, and the other end of the swing arm 51 is fixed so as to prevent the swing arm from rotating. It should be noted that, the connecting shaft 52 may be disposed on the turning plate 30, and the second locking member 31 may be disposed on the end positioning plate 42, so that the rotation function of the swing arm 51 is not affected by the exchange of the two members.

As shown in fig. 2 and 5, the first locking member 53 includes a rotatable insertion rod 531, one end of the insertion rod 531 is formed with a radially protruding locking portion 532, the second locking member 31 is a through slot 311, and when locked, the locking portion 532 passes through the through slot 311 from the front side of the through slot 311 and extends to the back side of the flipping plate 30, and then the insertion rod 531 is rotated such that the locking portion 532 is locked to the back side of the flipping plate 30 and cannot be retracted forward from the through slot 311, i.e., the insertion rod 531 is locked in the through slot 311 (see fig. 3).

Specifically, in the present embodiment, the engaging portion 532 is a part (see fig. 3) with a narrow middle and two ends protruding outwards, for example, an outer shape formed by cutting a circular arc from opposite sides of a cylinder. The through groove 311 is a narrow and long through hole structure, when the extension direction of the clamping portion 532 and the through groove 311 are consistent, the clamping portion 532 can pass through the through groove 311 to enter the back surface of the turnover plate 30, and at this time, if the clamping portion 532 rotates, the plugging rod 531 is fixed in the through groove 311 and cannot be retracted forward because the width of the clamping portion is greater than that of the through groove 311.

As shown in fig. 5, in order to conveniently rotate the plugging rod 531, the plugging rod 531 is provided with a handle portion 533 protruding outwards, so as to be convenient for a worker to grasp. In addition, the end of the swing arm 51 is fixedly provided with a sleeve 534 accommodating the rotation of the insertion rod 531, the insertion rod 531 is rotatably provided in the sleeve 534, and the side surface of the sleeve 534 is provided with a limit groove 535 through which the handle portion 533 protrudes. Preferably, the two ends of the limit slot 535 exactly correspond to the positions of the clamping part 532 and the through slot 311, i.e. when the handle part 533 is located at one end of the limit slot 535, the clamping part 532 is exactly aligned with the through slot 311 and can enter the through slot 311; when the handle portion 533 is located at the other end of the limit groove 535, the locking portion 532 is offset from the through groove 311, and the locking portion 532 cannot be retracted from the through groove 311.

In addition, the first locking member 53 and the second locking member 31 may be formed by a hook between two hooks, or may be formed by a detachable structure such as a safety buckle, and the first locking member 53 and the second locking member 31 may be locked to each other.

As shown in fig. 2, in order to achieve the clamping of the head 91, the swing arm 51 is provided with a clamping plate 54 movable toward the installation space, and a driving member 55 for driving the clamping plate 54 to move, in this embodiment, the clamping plate 54 is a flat plate, and the bottom of the clamping plate 54 is connected to the air inlet at the top of the head 91 when clamping. The driving part 55 employs a cylinder, which is fixedly provided on the swing arm 51 in the longitudinal direction, a piston rod of which faces the installation space and is connected to the clamping plate 54, thereby controlling the movement of the clamping plate 54 toward the installation space and ensuring that a sufficient clamping force is provided. In other embodiments, the drive member may be a screw, such as a threaded screw coupled to a rotating plate and fixedly coupled at one end to the clamping plate 54, such that movement of the clamping plate 54 is achieved by simply rotating the screw, and the threaded engagement provides a greater clamping force.

As shown in fig. 2, the clamping plate 54 is further provided with a guide rod 56, the guide rod 56 extends towards the position where the installation space is located, and the upper end of the guide rod 56 is arranged on the swing arm 51 in a penetrating manner, so that the clamping plate 54 can only move in a preset position without shifting when moving up and down, and the clamping plate 54 is ensured to be accurately clamped on the machine head 91.

As shown in fig. 2, the side of the flipping plate 30 facing the installation space is further provided with a positioning member 32, and the positioning member 32 positions the rear side of the head 91 when installed, so that the front and rear positions of the head 91 are accurate, thereby further ensuring that the clamping plate 54 can be accurately clamped on the head 91. In this embodiment, the positioning member 32 is a rotating block rotatably provided on the flipping plate 30, and an elastic member (e.g., a torsion spring) is connected to the rotating block, so that one end of the rotating block extends toward the installation space, and provides a restraining force to the rear side of the handpiece 91 so as to be in a correct installation position.

Specifically, in the present embodiment, as shown in fig. 2, the front side of the flipping plate 30 is provided with a hinge seat 33, both ends of the positioning member 32 are hinged in the hinge seat 33 by a shaft connection, and a torsion spring is provided on the positioning member 32, so that an elastic force is formed on the positioning member 32 to position the rear side of the head 91.

When the positioning rod 60 is inserted into the first positioning hole 34, the flipping plate 30 is in the first position; when the positioning rod 60 is inserted into the second positioning hole 35, the flipping plate is in the second position. In order to facilitate the control of the movement of the positioning rod 60, the positioning rod 60 is provided with a positioning cylinder 61 for controlling the linear movement thereof.

Further, in order to facilitate the insertion of the positioning rod 60 into the corresponding positioning hole, the positioning hole is a tapered hole with a large outer end and a small inner end, and the corresponding positioning rod 60 is a tapered rod with a small front end and a large rear end, so that when in use, the positioning rod 60 can smoothly enter the positioning hole under the action of the tapered surface as long as the positioning rod 60 is approximately aligned with the positioning hole, and the positioning of the positioning rod 60 is facilitated.

In addition, in order to balance the stress in the rotation process of the turnover plate 30, a balancing weight 70 is further disposed on the upper portion of the turnover plate 30, and the balancing weight 70 balances the weight of the turnover plate 30 after the machine head 91 is mounted thereon, so that the center of gravity of the turnover plate 30 is approximately at the center position, so that the turnover plate 30 can be turned. As shown in fig. 3, the turning plate 30 is further provided with a handle 80, and when the turning plate 30 needs to be rotated, the handle 80 can be grasped, so as to drive the turning plate 30 to rotate around the rotating shaft 20.
