Description

Technical Field

[0001] The invention relates to the technical field of plunger pump manufacturing, and in particular to a positioning mechanism and a production line having the same. Background Art

[0002] At present, plunger pumps belong to volumetric pumps and reciprocating pumps. The plunger pump reciprocates in the plunger cylinder, causing the change in the sealed volume in the plunger cylinder to generate a pressure difference to make the fluid medium work. The plunger pump is an important working part in hydraulic and pneumatic transmission, and the copper sleeve is a common component in the assembly process of the plunger pump. In the production process of the plunger pump cylinder, after cleaning the cylinder, it is necessary to roll the multiple cylinder holes of the cylinder in turn and press the copper sleeve into it to fix the copper sleeve and the cylinder together.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] like Figures 1 to 3As shown, embodiment 1 of the present invention provides a positioning mechanism 10, including a positioning member 11, a lifting structure 12 and a rotating structure 13, wherein the shape of the positioning member 11 is adapted to the shape of the cylinder hole 91 of the cylinder body 90; the lifting portion of the lifting structure 12 is movably arranged and drivingly connected to the rotating structure 13 to drive the rotating structure 13 to move to a predetermined positioning position at a predetermined height; the rotating portion 131 of the rotating structure 13 is movably arranged and drivingly connected to the positioning member 11 to drive the positioning member 11 to rotate; wherein the positioning member 11 is liftably or telescopically arranged on the rotating portion 131; when the rotating structure 13 drives the positioning member 11 to move to a position in contact with the outer wall of the cylinder body 90, the positioning member 11 rises or shortens; when the rotating structure 13 drives the positioning member 11 to move to the cylinder hole 91 of the cylinder body 90, the positioning member 11 descends or extends to extend into the cylinder hole 91, and drives the cylinder body 90 to rotate to a preset position through the rotating structure 13 and the positioning member 11.

[0041] By adopting the technical solution provided in this embodiment, the rotating structure 13 can smoothly drive the positioning member 11 to move to a position where it is inserted into a cylinder hole 91. Then, the rotating structure 13 drives the cylinder body 90 to rotate to a preset position through the positioning member 11. In this way, the cylinder hole 91 with the positioning member 11 inserted can be positioned. Since the number of cylinder holes 91 of the cylinder body 90 and the distribution angles of each cylinder hole 91 are already known at the time of production, thus, according to the positional relationship between the remaining cylinder holes 91 and the cylinder hole 91 with the positioning member 11 inserted (the positional relationship here mainly refers to the angle relationship), the position (mainly refers to the angle) of the remaining cylinder holes 91 can be known by taking the positioning of the cylinder hole 91 with the positioning member 11 inserted as a reference, so that the automatic positioning of all cylinder holes 91 of the cylinder body 90 can be realized, and the position of all cylinder holes 91 can be known, so as to facilitate the subsequent automatic operation of each cylinder hole 91 of the cylinder body 90 in sequence or the simultaneous automatic operation of multiple cylinder holes 91, and facilitate the realization of high consistency and high precision of the overall operation process, and improve the convenience and efficiency of the operation of each cylinder hole 91 of the cylinder body 90. Therefore, the positioning mechanism 10 provided in this embodiment can solve the technical problem of the inconvenience of positioning the cylinder hole 91 of the cylinder body 90 in the prior art.

[0042] Specifically, the design of the positioning member 11 takes into account the geometric shape of the cylinder bore 91 of the cylinder body 90, ensuring that the positioning member 11 can accurately extend into the cylinder bore 91 when it moves to the cylinder bore 91. The positioning member 11 is arranged on the rotating portion 131 of the rotating structure 13 in a liftable or telescopic manner, ensuring that the positioning member 11 can adjust its position relative to the cylinder body 90 accordingly when it contacts different parts of the cylinder body 90, so that the positioning member 11 can be smoothly inserted into the cylinder bore 91 when it moves to the cylinder bore 91, thereby realizing the automated positioning function. Specifically, when the positioning member 11 is inserted into the cylinder bore 91 and drives the cylinder body 90 to rotate to a preset position, it can be understood that the cylinder body 90 rotates relative to the symmetry axis of the cylinder body 90 itself, and thus the main function is to adjust the angle of the cylinder bore 91.

[0043] In addition, the precise control of the rotating structure can ensure the stability and positioning accuracy of the cylinder body 90 during the processing, which is convenient for the subsequent automation of the subsequent processes of the cylinder body 90 and avoids the errors that may be caused by manual operation. Specifically, the subsequent processes include the rolling of the cylinder hole 91 and the press-fitting of the copper sleeve. Through the precise positioning of the positioning mechanism 10, it can also ensure that the positions of each cylinder hole 91 are effectively obtained in the subsequent rolling of the cylinder hole 91 and the press-fitting of the copper sleeve, so as to facilitate the automated production process of the overall process in cooperation with the rolling mechanism 30 and the press-fitting mechanism 40, so as to ensure that the positions in the subsequent rolling and copper sleeve press-fitting processes are accurate, avoid the positioning errors that may be caused by manual operation, improve the consistency of rolling and press-fitting, ensure the fixing quality of the copper sleeve and the cylinder body 90, and thus improve the performance and reliability of the final product.

[0044] Specifically, the positioning mechanism 10 further includes an elastic member 14, one end of which is fixedly arranged, and the other end of which is connected to the positioning member 11, so that the positioning member 11 can be lifted and lowered under the elastic force of the elastic member 14. In this way, when the positioning member 11 moves to contact the outer wall of the cylinder body 90, the elastic member 14 can be compressed, so that the positioning member 11 can be lifted, and the situation that the positioning member 11 is stuck with the outer wall of the cylinder body 90 can be avoided, so that the rotating structure 13 can smoothly drive the positioning member 11 to move; when the positioning member 11 moves to the cylinder hole 91 of the cylinder body 90, the elastic member 14 restores the deformation, so that the positioning member 11 can be lowered, so that the positioning member 11 can smoothly fall into the cylinder hole 91, and the positioning member 11 can smoothly cooperate with the cylinder hole 91. Specifically, one end of the elastic member 14 can be fixed to the rotating structure 13 or a component fixedly connected to the rotating structure 13, so that the positioning member 11 can smoothly rotate with the rotation of the rotating structure 13.

[0045] Specifically, the elastic member 14 in this embodiment can be a spring, a part of which is sleeved on the positioning member 11. Specifically, the positioning member 11 can be a strip structure, and a positioning step can be further provided on the positioning member 11, through which the other end of the spring is abutted or connected.

[0046] In this embodiment, a mounting hole matching the shape of the positioning member 11 is provided on the rotating portion 131, and the positioning member 11 is arranged in the mounting hole for lifting. In this way, it can be ensured that the rotating mechanism can smoothly drive the positioning member 11 to rotate together, so that the positioning member 11 can also be smoothly lifted and lowered in the mounting hole, which is convenient for ensuring the lifting and lowering of the positioning member 11, and also convenient for realizing stable guidance of the lifting and lowering of the positioning member 11, so as to finally realize the effect that the positioning member 11 can be smoothly inserted into one of the multiple cylinder holes 91 and the position of the cylinder hole 91 is positioned.

[0047] Specifically, the positioning member 11 can be lifted and lowered on the rotating part 131, and the positioning mechanism 10 also includes a first detection member 15, an elastic member 14 and a second detection member 16. The first detection member 15 is installed on the rotating part 131; one end of the elastic member 14 is fixedly connected to the first detection member 15, and the other end of the elastic member 14 is connected to the positioning member 11; the detection part of the second detection member 16 is arranged toward the first detection member 15, so as to detect the height position of the first detection member 15 through the second detection member 16. The first detection member 15 and the second detection member 16 are arranged in coordination, which can be used to accurately detect the lifting height of the first detection member 15, so as to determine the lifting height of the rotating part 131. Specifically, during the positioning process of the positioning mechanism 10, the second detection member 16 should detect that the first detection member 15 has dropped to a preset height. When the first detection member 15 has dropped to a preset height, it can ensure that the spring can be inserted into the cylinder hole 91 and inserted to a certain preset depth without being elastically deformed, thereby ensuring the subsequent coordination stability of the positioning member 11 and the cylinder hole 91.

[0048] Specifically, the outer dimensions of the positioning member 11 and the distance between the positioning member 11 and the rotating shaft of the rotating structure 13 can be adaptively adjusted according to the size of different cylinder bodies 90 and the layout of cylinder holes 91 to adapt to different cylinder bodies 90 and cylinder holes 91.

[0049] Specifically, the rotating structure includes a servo motor 132, which is drivingly connected to the rotating part 131; wherein, when the rotating structure 13 is in the pre-positioning position, the servo motor 132 drives the rotating part 131 to rotate forwardly by a debugging angle with a debugging number of steps, so that the rotating part 131 moves from the initial position to the debugging position, and the positioning member 11 cooperates with the cylinder hole 91; after the rotating part 131 is in the debugging position, the servo motor 132 drives the rotating part 131 to rotate reversely by a debugging angle with a debugging number of steps, so that the rotating part 131 returns from the debugging position to the initial position; after the rotating part 131 returns to the initial position, the servo motor 132 drives the rotating part 131 to rotate by a preset angle with a set positioning number of steps, so that the cylinder body 90 moves to the preset position. With such a setting, by controlling the number of steps of the servo motor 132, the position of the cylinder hole 91 of the cylinder body 90 with the positioning piece 11 inserted therein can be accurately positioned, and according to the number of positioning steps, other subsequent operating equipment can facilitate the rotation of the cylinder body 90 according to the angle between two adjacent cylinder holes 91, so that each cylinder hole 91 can be positioned in turn or multiple cylinder holes 91 can be positioned simultaneously, which is convenient for realizing sequential operation or synchronous operation of multiple cylinder holes 91.

[0050] Specifically, the rotating structure 13 mainly includes a servo motor 132 and a rotating part 131. The servo motor 132 is connected to the rotating part 131 through a driving coupling. A positioning member 11 is installed on the rotating part 131, and the positioning member 11 is used to cooperate with the cylinder hole 91 of the cylinder body 90. The servo motor 132 drives the rotating part 131 to rotate in the forward direction by the debugging angle according to the preset debugging steps. This process is to fine-tune the position of the rotating part 131 to ensure that the positioning member 11 can accurately align with the cylinder hole 91 during the rotation process. When the rotating part 131 rotates to the debugging position, the positioning member 11 will move to the cylinder hole 91 and be inserted into the cylinder hole 91. When the rotating part 131 reaches the debugging position, the servo motor 132 then drives the rotating part 131 to rotate in the reverse direction by the debugging angle again according to the debugging steps, so that the rotating part 131 returns to the initial position. Subsequently, the servo motor 132 drives the rotating part 131 to rotate a preset angle with a set number of positioning steps, and accurately moves the cylinder body 90 to a preset position, thereby achieving accurate positioning of the corresponding cylinder hole 91 into which the positioning member 11 is inserted.

[0051] Specifically, the debugging angle and the number of debugging steps are accurately calculated according to the specific size and position of the cylinder hole 91 to achieve the optimal alignment effect. Preferably, as long as the debugging angle is not less than the angle between two adjacent cylinder holes 91 (the angle between two cylinder holes 91 can be understood as the angle between the line connecting the center of one cylinder hole 91 and the center of the top of the cylinder body 90 and the line connecting the center of the other cylinder hole 91 and the center of the cylinder body 90). However, considering that the cylinder hole 91 itself has a certain size, the debugging angle can also be set to be slightly smaller than the angle between the two cylinder holes 91. Specifically, the minimum debugging angle can be set to the angle between two adjacent cylinder holes 91 minus 15°.

[0052] Specifically, the cylinder body 90 in this embodiment may be provided with 9 cylinder holes 91 or 7 cylinder holes 91 evenly distributed. In this embodiment, the preset angle may preferably be set to 40°. Alternatively, the preset angle may also be set to 30°. Specifically, since the cylinder hole 91 itself has a certain size, when the preset angle is set to 30°, it can also ensure that the positioning member 11 can smoothly enter into one cylinder hole 91.

[0053] like Figures 4 to 11 As shown, the second embodiment of the present invention provides a production line, including the positioning mechanism 10 provided in the first embodiment; the production line includes a positioning tool 20, at least part of which is movably arranged to move to a positioning position for positioning the cylinder body 90 or a loosening position for loosening the cylinder body 90; wherein, when the rotating structure 13 of the positioning mechanism 10 and the positioning member 11 of the positioning mechanism 10 drive the cylinder body 90 to rotate to a preset position, the positioning tool 20 moves to the positioning position. With such a structural arrangement, it is convenient to realize the positioning of the cylinder hole 91 of the cylinder body 90 when the cylinder body 90 is rotated to a preset position, and the positioning of the cylinder body 90 is realized by the positioning tool 20, so as to ensure that the relative position of the positioning tool 20 and the cylinder body 90 does not change, and ensure the positioning effect of the cylinder hole 91 of the cylinder body 90.

[0054] Specifically, in order to ensure that the rotating mechanism drives the cylinder body 90 to rotate around the axis of symmetry of the cylinder body 90, a positioning groove can be provided on the positioning tooling 20, and the cylinder body 90 is located in the positioning groove to avoid as much as possible the situation where the cylinder body 90 has a large overall position deviation in addition to the angle change during the rotation of the cylinder body 90 driven by the rotating structure 13.

[0055] Specifically, the positioning tool 20 is used to realize the clamping and positioning of the cylinder body 90 at the preset position. Specifically, the positioning tool 20 can be a positioning claw structure to ensure the stability of positioning the cylinder body 90 at the preset position. The positioning claw structure includes three claws arranged at intervals along the circumferential direction.

[0056] In this embodiment, the cylinder body 90 has a plurality of cylinder holes 91; the production line also includes an operating component, which is used to sequentially operate the plurality of cylinder holes 91; the positioning fixture 20 includes a positioning seat 21 and a positioning clamp 22, the positioning seat 21 is rotatably arranged around the clamping center axis of the positioning clamp 22; the positioning clamp 22 is arranged on the positioning seat 21, and the positioning clamp 22 forms at least part of the positioning fixture 20; wherein the positioning seat 21 drives the positioning clamp 22 to rotate to a plurality of operating positions where the plurality of cylinder holes 91 are sequentially arranged relative to the operating part of the operating component. With such a structural arrangement, it is possible to facilitate the automated operation process of the plurality of cylinder holes 91, ensure the position accuracy during the operation process, and further ensure the operation accuracy.

[0057] Specifically, the positions and layouts of the multiple cylinder holes 91 on the cylinder body 90 are determined. When the cylinder body 90 is positioned at the preset position, the position of the cylinder hole 91 into which the positioning member 11 is inserted is determined. Subsequently, according to the angle difference between two adjacent cylinder holes 91, the cylinder body 90 is driven by the positioning seat 21 to rotate each time according to the angle difference between the two cylinder holes 91, so that the corresponding working positions of each cylinder hole 91 and the operating part of the working component can be realized in turn, thereby ensuring the automated operation of the multiple cylinder holes 91.

[0058] In this embodiment, the positioning tool 20 also includes a positioning disk 23, which is movably arranged, and the positioning seat 21 is rotatably arranged on the positioning disk 23, so that the positioning disk 23 drives the positioning seat 21 to move to a positioning position arranged relative to the positioning mechanism or an operating position arranged relative to the operating component. With such a structural arrangement, it is convenient to synchronously realize the synchronous operation of at least two cylinder bodies 90, so that the positioning mechanism 10 positions one cylinder body 90, and the operating component operates the other cylinder body 90, thereby improving the overall automated operation efficiency. Specifically, the positioning disk 23 rotates cyclically around its own axis.

[0059] Specifically, the operating parts include a rolling mechanism 30 and a pressing mechanism 40. The rolling part 31 of the rolling mechanism 30 is used to extend into the cylinder hole 91 to shape the edge of the cylinder hole 91. The pressing part 41 of the pressing mechanism 40 is used to press the copper sleeve into the cylinder hole 91. The operating station includes a rolling station and a pressing station. Among them, at least three positioning seats 21 and at least three positioning clamps 22 are arranged on the positioning plate 23. The at least three positioning seats 21 are arranged one by one with the at least three positioning clamps 22. Each positioning clamp 22 can be movably arranged on the corresponding positioning seat 21. At least three positioning seats 21 are arranged at intervals along the circumference of the positioning plate 23. The positioning plate 23 is rotatably arranged so that one of the at least three positioning seats 21 is in the positioning station, another is in the rolling station, and another is in the pressing station. In this way, it is possible to facilitate synchronous operation of at least three cylinder bodies 90 to ensure that each cylinder body 90 is positioned, rolled and pressed in sequence, thereby better improving the efficiency of automated production.

[0060] Specifically, at least three positioning seats 21 and three positioning clamps 22 may be provided on the positioning plate 23, so that the next workstation can be switched every time the positioning plate 23 rotates 120°.

[0061] Specifically, the production line further includes a rolling mechanism 30, which includes a first frame 32 and a rolling portion 31 that can be raised and lowered on the first frame 32, so that the rolling portion 31 can extend into the cylinder hole 91 or come out of the cylinder hole 91. With such a structural arrangement, it is convenient to automatically realize the rolling operation of the cylinder hole 91. Specifically, the rolling portion 31 here can be a special tool, and the rolling process can be understood as: squeezing the edge of the cylinder hole 91 by a special tool, so that the edge of the cylinder hole 91 undergoes a slight plastic deformation, so as to facilitate the subsequent pressing of the copper sleeve into the cylinder hole 91.
