Description

Technical Field

[0001] The utility model relates to the technical field of screw pump production, in particular to a screw pump stator buckling machine. Background Art

[0002] The screw pump is a single screw transport pump. Its main working parts are the eccentric spiral screw (called the rotor) and the screw bushing (called the stator) with a double-line spiral surface on the inner surface. Its working principle is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis on the one hand, and rolls along the inner surface of the bushing on the other hand, thus forming a sealed chamber of the pump. When installing the stator of the screw pump, a coupling is required to achieve the connection between the motor and the stator. At present, the coupling and the stator are mostly connected by a screw-on machine. The existing screw-on machine usually installs a rotating tooth on the transmission dial, a fixed tooth on the mounting frame, and a coupling and a stator on the rotating tooth and the fixed tooth respectively. After the indirect drive of the motor, the rotating tooth drives the coupling to rotate, and the coupling is screwed on the threaded end of the stator. This connection method reduces labor costs and has a certain work efficiency. However, when the existing screw-on machine is used, since the rotating teeth and the fixed teeth are designed according to the couplings and stators of different specifications, the rotating teeth and the fixed teeth often need to be replaced when the couplings and stators of different specifications are connected, which makes the operation more cumbersome. To this end, we provide a screw pump stator screw-on machine to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0014] The utility model proposes a screw pump stator buckling machine, comprising a frame 1, a transmission dial 2 is rotatably arranged on the frame 1, a driving assembly 3 is connected to the shaft end of the transmission dial 2, a fixed chuck 21 is fixedly installed on the other end of the transmission dial 2, the driving assembly 3 can drive the fixed chuck 21 to rotate through the transmission dial 2, and a slide plate 4 is slidably arranged on the side of the fixed chuck 21 away from the transmission dial 2 on the frame 1, and a fixing assembly 5 is arranged on the slide plate 4;

[0015] The fixing assembly 5 includes a slot plate 51, which is fixedly arranged on the top of the slide plate 4, and a double-headed screw 52 is rotatably arranged in the inner cavity of the slot plate 51, and a handwheel 53 is fixedly arranged at one end of the double-headed screw 52. The rotation of the handwheel 53 can drive the double-headed screw 52 to rotate, and slot blocks 54 are threadedly connected on both sides of the outer wall of the double-headed screw 52. The two slot blocks 54 are correspondingly arranged, and the bottom ends of the slot blocks 54 are slidably connected to the inner cavity of the slot plate 51. The clamping axis of the two slot blocks 54 corresponds to the clamping axis of the fixed chuck 21. The rotating double-headed screw 52 can drive the two slot blocks 54 to approach each other, so that the stator is clamped and fixed by the slots of the two slot blocks 54.

[0016] Specifically, the frame 1 is provided with two sliding bars 11 below the slide plate 4. The two sliding bars 11 are arranged in parallel, and the outer walls of the two sliding bars 11 are sleeved with sliding sleeves 12. The sliding sleeves 12 are fixedly arranged at the bottom of the slide plate 4. Through the cooperation of the sliding bars 11 and the sliding sleeves 12, the movement of the slide plate 4 can be limited so that the slide plate 4 can be close to or away from the fixed chuck 21.

[0017] Specifically, the driving assembly 3 includes a motor 31, which is installed on the top of the frame 1. The output end of the motor 31 is connected to a reducer 32. The operation of the motor 31 can reduce the output speed through the reducer 32. The output end of the reducer 32 is connected to a driving gear 33. A driven gear 34 is meshed on one side of the outer wall of the driving gear 33. The driven gear 34 is fixed to the shaft end of the transmission dial 2. The size of the driving gear 33 is smaller than that of the driven gear 34. The speed is further reduced by the meshing of the driving gear 33 and the driven gear 34.

[0018] Specifically, the slot of the slot block 54 is machined with grinding grooves, and its design purpose is to further stably fix the stator, and a handle 41 is installed on the top of the slide plate 4. The user can use the handle 41 to drive the slide plate 4 and the stator close to the fixed chuck 21, and then make the stator close to the coupling and connect it.

[0019] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0020] Working principle: When using the buckle machine, the user can fix the coupling in the fixed chuck 21, and set the stator between the corresponding slot blocks 54 and turn the hand wheel 53. The rotating double-headed screw 52 can drive the two slot blocks 54 to approach each other, so that the stator is fixed. At this time, the motor 31 is started. Under the operation of the motor 31, the output speed can be reduced by the reducer 32, and the speed is reduced again by the engagement of the driving gear 33 and the driven gear 34. At this time, the motor 31 indirectly drives the fixed chuck 21 to rotate and the coupling to rotate. The user drives the slide plate 4 and the stator to approach and connect with the coupling through the handle 41. When the coupling rotates a certain number of times, it can completely enter the threaded end of the stator. At this time, stopping the operation of the motor 31 realizes the connection between the coupling and the stator. Since an approximately square slot is formed between the two slot blocks 54, stators of different specifications can be centered in the slot of the slot block 54, and are consistent with the axis of the fixed chuck 21, so that the buckle machine does not need to frequently replace the rotating teeth and the fixed teeth, and has certain practicality.
