[0003] Specifically, the pump core includes a cylinder body, a piston, a mounting plate, a driven gear and a connecting rod. The piston is arranged in the cylinder body, and the mounting plate is connected to the cylinder body. A rotating hole for installing a bearing is also opened on the mounting plate. The outer ring of the bearing is interference fit with the inner wall of the rotating hole. The rotating shaft of the driven gear is connected to the inner ring of the bearing so that the driven gear can be rotatably connected to the mounting plate. The driving device is a rotating motor. A driving gear is provided on the driving shaft of the rotating motor. The driving gear and the driven gear are meshed with each other. One end of the connecting rod is eccentrically connected to the driven gear, and the other end is connected to the piston, so that the driven gear can be driven to rotate by the driving device, and then the piston is driven to move in the cylinder body via the connecting rod.
[0004] In the conventional installation of pump core bearings, workers will first place the bearings above the mounting holes, and then use hammers or other knocking tools to knock the bearings into the mounting holes. However, this way of installing bearings is not only easy to cause damage to the bearings or pump cores, but also easy to cause the bearings to deviate in the mounting holes and fail to install because the bearings are knocked at different positions and with different knocking forces each time, and the installation accuracy is low.
[0005] In view of this, it is necessary to provide a bearing auxiliary locking device for a stamping pump and an application method thereof. Summary of the invention
[0006] In order to solve the problem of low installation accuracy and easy damage to the bearing or pump core when using a knocking tool to install the bearing of the pump core, the present application provides a bearing auxiliary locking device for a stamping pump and an application method thereof.
[0007] In the first aspect, the present application provides a bearing auxiliary locking device for a stamping pump, which adopts the following technical solution: comprising a frame and a press-fit assembly, wherein the frame comprises a receiving seat, and the receiving seat is provided with a receiving groove for receiving a pump core of the stamping pump;
[0008] The press-fitting assembly includes a press-fitting part and a driving device. The pump core is provided with a mounting hole for mounting a bearing. The driving device is arranged on the frame, and the driving device is transmission-connected to the press-fitting part and can drive the press-fitting part to approach or move away from the mounting hole.

[0009] By adopting the above technical solution, when installing the bearing on the pump core, the worker can first place the pump core to be press-fitted with the bearing in the receiving groove, then place the bearing above the mounting hole and align the bearing with the mounting hole, then start the driving device to drive the pressing part close to the mounting hole and press the bearing into the mounting hole, finally drive the pressing part away from the pressing hole by the driving device and remove the pressed pump core from the receiving groove, and the installation of the bearing can be completed, so that the worker does not need to use a hammer or other knocking tools to knock the bearing into the mounting hole, ensuring that the bearing or the pump core will not be damaged due to knocking; in the process of pressing the bearing with the pressing part, the pressing part can always abut against the same position of the bearing and stably push the bearing into the mounting hole, so that the bearing is not easy to deflect in the mounting hole, and the installation accuracy is high.
[0010] Specifically, the driving device is a telescopic cylinder, a cylinder body of the telescopic cylinder is connected to the frame, and a piston rod of the telescopic cylinder is connected to the press-fitting part;
[0011] The end of the press-fitting part away from the telescopic cylinder is a butting end, and the butting end can butt against the outer ring of the bearing.
[0012] By adopting the above technical solution, the piston rod of the telescopic cylinder can drive the press-fitting part to approach or move away from the mounting hole, so that the press-fitting part can press the bearing into the mounting hole; the press-fitting part can abut against the outer ring of the bearing to ensure that when the bearing is pressed, the press-fitting part does not abut against the outer ring of the bearing but abuts against the inner ring or other parts of the bearing, causing the bearing to be damaged due to excessive axial force.
[0013] Furthermore, a limiting protrusion is provided on the bottom wall of the accommodating groove, and a positioning hole is opened on the pump core. When the accommodating groove accommodates the pump core, the limiting protrusion can be inserted into the positioning hole and abut against the inner wall of the positioning hole.
[0014] By adopting the above technical solution, the limiting protrusion can cooperate with the positioning hole of the pump core to limit the pump core, so that the pump core is not easy to shake in the installation groove, thereby ensuring the accurate installation of the bearing when the press-fit assembly is press-fitting the bearing.
[0015] Furthermore, it also includes a bearing limiting assembly, the bearing limiting assembly includes a limiting rod, the limiting rod is arranged on the bottom wall of the accommodating groove, the inner ring of the bearing can be sleeved on the limiting rod and abut against the rod wall of the limiting rod;
[0016] A clearance groove is provided on the abutting end, and when the abutting end abuts against the bearing, the limiting rod can enter into the clearance groove.
[0017] By adopting the above technical solution, the limit rod can abut against the inner ring of the bearing and limit the bearing, so that workers can quickly align the bearing and the mounting hole by putting the inner ring of the bearing on the limit rod; the design of the limit rod and the clearance groove enables the limit rod to continuously limit the bearing during the process of press-fitting the bearing with the press-fit part, so that the bearing is not easily deflected in the mounting hole, thereby ensuring the precise installation of the bearing.
[0018] Furthermore, the bearing limit assembly further comprises a limit sleeve and a limit bolt, the limit sleeve can be sleeved on the press-fitting part, a pair of waist-shaped holes are relatively opened on the tube wall of the limit sleeve, each waist-shaped hole is opened along the moving direction of the press-fitting part, and the press-fitting part is opened with a mounting through hole corresponding to the waist-shaped hole;
[0019] The screw end of the limiting bolt can sequentially pass through one of the pair of waist-shaped holes, the mounting through hole and the other of the pair of waist-shaped holes and be screwed with a nut, so that the limiting sleeve is connected to the press-fitting part, and the inner wall of each waist-shaped hole can abut against the limiting bolt;
[0020] When the telescopic cylinder drives the press-fitting part to approach the mounting hole, the limiting sleeve can be sleeved on the bearing and abut against the outer ring of the bearing. After the limiting sleeve abuts against the pump core, the telescopic cylinder can also drive the press-fitting part to move along the length direction of the limiting sleeve and press the bearing into the mounting hole.
[0021] By adopting the above technical scheme, the limit bolt can cooperate with the waist-shaped hole to limit the moving distance of the press-fit part in the limit sleeve; in the process of the telescopic cylinder driving the press-fit part to approach and press-fit the bearing, the limit sleeve will first contact the bearing and be sleeved on the bearing, so that the outer ring of the bearing abuts against the inner wall of the limit sleeve, and then after the limit sleeve and the pump core abut and stop moving, the telescopic cylinder will continue to drive the press-fit part to move along the inside of the limit sleeve and press the bearing into the mounting hole, so that the outer ring of the bearing can be limited by the limit sleeve, so that the bearing is not easy to deflect in the mounting hole, thereby realizing precise installation of the bearing.
[0022] Furthermore, the press-fitting part is provided with an abutting protrusion, and an elastic member is provided between the abutting protrusion and the limiting sleeve, and the elastic member can apply a force to the limiting sleeve to approach the accommodating groove.
[0023] By adopting the above technical solution, after the bearing is pressed, when the telescopic cylinder drives the pressed part away from the pump core, the elastic part can apply a force close to the accommodating groove to the limiting sleeve, so that the limiting sleeve can move in the direction close to the accommodating groove until the limiting bolt abuts against the top of the waist-shaped hole, thereby making the pressed part retract into the limiting sleeve, ensuring that the next time the bearing is pressed, the limiting sleeve will not be unable to limit the outer ring of the bearing due to the pressed part not being retracted into the limiting sleeve, so that the bearing can be accurately installed.
[0024] Further, the press-fitting part includes a mounting rod and an abutment joint, the mounting rod is provided with the mounting through hole, one end of the mounting rod is connected to the piston rod of the telescopic cylinder, and the other end of the mounting rod is provided with a magnetic attraction part, and the magnetic attraction part can magnetically fix the abutment joint on the mounting rod;

[0026] By adopting the above technical solution, workers can first select an appropriate abutment joint according to the size of the bearing to be press-fitted, and then directly magnetically fix the abutment joint on the magnetic attraction part of the mounting rod, so that the press-fitting assembly can press-fit bearings of different sizes.
[0027] Furthermore, the limiting sleeve comprises a connecting sleeve and a limiting tube, the connecting sleeve is provided with a pair of waist-shaped holes so that the connecting sleeve can be connected to the mounting rod via the limiting bolt, and the outer wall of the connecting sleeve is provided with an external thread;
[0028] One side of the limit tube is provided with an internal thread matched with the external nut and can be threaded with the connecting tube, and the other side of the limit tube can be sleeved on the bearing to make the outer ring of the bearing abut against the inner wall of the limit tube.
[0029] By adopting the above technical solution, workers can first select an appropriate limiting tube according to the size of the bearing to be pressed, and then thread the limiting tube with the connecting sleeve, so that the limiting sleeve can cover bearings of different sizes and make the outer ring of the bearing abut against the inner wall of the limiting sleeve, so that the bearing limiting assembly can limit bearings of different sizes.
[0030] The second aspect of the present application provides an application method of a bearing auxiliary locking device for a stamping pump, which adopts the following technical solution:
[0031] Preliminary step: firstly selecting an adaptable abutment joint and a stopper tube according to the size of the bearing to be press-fitted, and then installing the abutment joint and the stopper tube on the press-fitting assembly;
[0032] Workpiece placement step: firstly place the pump core to be installed with the bearing into the receiving groove, and make the limiting protrusion enter the positioning hole of the pump core, then sleeve the inner ring of the bearing on the limiting rod, and make the outer ring of the bearing abut against the orifice of the installation hole of the pump core;
[0033] Press-fitting steps: first drive the piston rod of the telescopic cylinder to extend from the cylinder body, so that the piston rod drives the press-fit part to approach and abut the bearing. After the bearing is pressed into the mounting hole, drive the piston rod of the telescopic cylinder to retract into the cylinder body, and remove the pump core with the press-fitted bearing from the accommodating groove.
[0034] By adopting the above technical scheme, workers can first install abutment joints and limit tubes of appropriate specifications on the bearing auxiliary locking device of the stamping pump through the preparatory steps, then place the pump core and bearing in place through the workpiece placement steps, and finally complete the press-fitting of the bearing through the press-fitting steps. This not only eliminates the need for workers to use hammers or other knocking tools to knock the bearing into the mounting hole, ensuring that the bearing or pump core will not be damaged due to knocking, but also enables the cooperation of the bearing limit assembly and the press-fitting part to prevent the bearing from being deflected in the mounting hole, thereby achieving high installation accuracy.

DETAILED DESCRIPTION
[0045] Figure 1 This is a three-dimensional diagram of a bearing auxiliary locking device of a stamping pump of the present application. Figure 2 is along Figure 1 Schematic cross-sectional view of the central axis of the middle press fitting. Figure 1 and Figure 2A bearing auxiliary locking device for a stamping pump includes a frame 1 and a press-fitting assembly 2. The frame 1 includes a receiving seat 11, and the receiving seat 11 is provided with a receiving groove for accommodating a pump core 3 of the stamping pump; the press-fitting assembly 2 includes a press-fitting part 21 and a driving device 22. The pump core 3 is provided with a mounting hole 31 for mounting a bearing 4. The driving device 22 is arranged on the frame 1, and the driving device 22 is transmission-connected with the press-fitting part 21 and can drive the press-fitting part 21 to approach or move away from the mounting hole 31. The press-fitting part 21 can abut against the bearing 4 and press the bearing 4 into the mounting hole 31.
[0046] Through the above design, when installing the bearing 4 on the pump core 3, the worker can first place the pump core 3 with the bearing 4 to be pressed into the receiving groove, then place the bearing 4 above the mounting hole 31 and align the bearing 4 with the mounting hole 31, then start the driving device 22 to drive the pressing part 21 close to the mounting hole 31 and press the bearing 4 into the mounting hole 31, finally drive the pressing part 21 away from the pressing hole by the driving device 22 and remove the pressed pump core 3 from the receiving groove, and the installation of the bearing 4 can be completed, so that the worker does not need to use a hammer or other knocking tools to knock the bearing 4 into the mounting hole 31, ensuring that the bearing 4 or the pump core 3 will not be damaged due to knocking; in the process of pressing the bearing 4 by the pressing part 21, the pressing part 21 can always abut against the same position of the bearing 4 and stably push the bearing 4 into the mounting hole 31, so that the bearing 4 is not easy to deflect in the mounting hole 31, and the installation accuracy is high.
[0047] See also Figure 1 and Figure 2 The driving device 22 is a telescopic cylinder, the cylinder body of the telescopic cylinder is connected to the frame 1, and the piston rod of the telescopic cylinder is connected to the press-fitting part 21. The telescopic cylinder can be a hydraulic cylinder, so that the piston rod of the telescopic cylinder can drive the press-fitting part 21 to approach or move away from the mounting hole 31, so that the press-fitting part 21 can press the bearing 4 into the mounting hole 31; the end of the press-fitting part 21 away from the telescopic cylinder is the abutment end, which can abut against the outer ring of the bearing 4 to ensure that when the bearing 4 is pressed, the press-fitting part 21 does not abut against the outer ring of the bearing 4 but abuts against the inner ring of the bearing 4 and other parts, so that the axial force of the bearing 4 is too large, resulting in damage to the bearing 4.
[0048] See also Figure 1 and Figure 2 A limiting protrusion 111 is provided on the bottom wall of the accommodating groove, and a positioning hole is opened on the pump core 3. When the accommodating groove accommodates the pump core 3, the limiting protrusion 111 can be inserted into the positioning hole and abut against the inner wall of the positioning hole, so that the pump core 3 can be limited by the cooperation between the limiting protrusion 111 and the positioning hole of the pump core 3, so that the pump core 3 is not easy to shake in the installation groove, so as to ensure the accurate installation of the bearing 4 when the press-fit assembly 2 presses the bearing 4.
[0049] Specifically, a limit platform matched with the mounting hole 31 of the pump core 3 can also be provided on the bottom wall of the accommodating groove. When the accommodating groove accommodates the pump core 3, the limit platform can be inserted into the mounting hole 31 and abut against the inner wall of the mounting hole 31, so that the pump core 3 can be limited by the cooperation between the limit platform and the mounting hole 31, so that the pump core 3 is less likely to shake in the mounting groove, so as to ensure the accurate installation of the bearing 4 when the press-fit assembly 2 presses the bearing 4.
[0050] See also Figure 1 and Figure 2 A bearing auxiliary locking device for a stamping pump also includes a bearing limiting assembly 5, which includes a limiting rod 51. The limiting rod 51 is arranged at the center of the limiting platform, and the inner ring of the bearing 4 can be sleeved on the limiting rod 51 and abutted against the rod wall of the limiting rod 51, so that workers can quickly align the bearing 4 and the mounting hole 31 by sleeved the inner ring of the bearing 4 on the limiting rod 51; a clearance groove 214 is opened on the abutting end, and when the abutting end abuts against the bearing 4, the limiting rod 51 can enter the clearance groove 214, so that in the process of press-fitting the bearing 4 by the press-fitting part 21, the limiting rod 51 can continuously limit the bearing 4, so that the bearing 4 is not easy to be deflected in the mounting hole 31, thereby ensuring the accurate installation of the bearing 4.
[0051] See also Figure 1 and Figure 2 The bearing limit assembly 5 also includes a limit sleeve 52 and a limit bolt 53. The limit sleeve 52 can be sleeved on the press-fitting part 21. A pair of waist-shaped holes are relatively opened on the tube wall of the limit sleeve 52. Each waist-shaped hole is opened along the moving direction of the press-fitting part 21. A mounting through hole corresponding to the waist-shaped hole is also opened on the press-fitting part 21; the screw end of the limit bolt 53 can sequentially pass through one of the pair of waist-shaped holes, the mounting through hole and the other of the pair of waist-shaped holes and be screwed with a nut to connect the limit sleeve 52 with the press-fitting part 21. The inner wall of each waist-shaped hole can abut against the limit bolt 53, so that the moving distance of the press-fitting part 21 in the limit sleeve 52 can be limited by the cooperation of the limit bolt 53 and the waist-shaped hole.
[0052] Through the above design, in the process of the telescopic cylinder driving the pressing part 21 to approach and press-fit the bearing 4, the limiting sleeve 52 will first contact the bearing 4 and be sleeved on the bearing 4, so that the outer ring of the bearing 4 abuts against the inner wall of the limiting sleeve 52, and then after the limiting sleeve 52 and the pump core 3 abut and stop moving, the telescopic cylinder will continue to drive the pressing part 21 to move along the inside of the limiting sleeve 52 and press the bearing 4 into the mounting hole 31, so that the outer ring of the bearing 4 can be limited by the limiting sleeve 52, so that the bearing 4 is not easy to deflect in the mounting hole 31, thereby realizing the precise installation of the bearing 4.
[0053] See also Figure 1 and Figure 2 A contact protrusion 211 is also provided on the press-fitting part 21, and an elastic member is provided between the contact protrusion 211 and the limiting sleeve 52, which can be a compression spring, so that after the press-fitting of the bearing 4 is completed, when the telescopic cylinder drives the press-fitting part 21 away from the pump core 3, the elastic member can apply a force close to the accommodating groove to the limiting sleeve 52, so that the limiting sleeve 52 can move in the direction close to the accommodating groove until the limiting bolt 53 abuts against the top of the waist-shaped hole, so that the press-fitting part 21 can be retracted into the limiting sleeve, ensuring that the next time the bearing 4 is press-fitted, the press-fitting part 21 will not be retracted into the limiting sleeve, so that the limiting sleeve will not be able to limit the outer ring of the bearing 4 due to the failure of the press-fitting part 21 to limit the outer ring of the bearing 4, so that the bearing 4 can be accurately installed.
[0054] Figure 3 is a schematic cross-sectional view of another embodiment of the present application taken along the central axis of the press-fitted part, Figure 4 yes Figure 3 A schematic enlarged view of the area A in FIG. 1 , showing the connecting sleeve and the stop tube. Figure 3 and Figure 4 In another embodiment provided in the present application, the press-fitting part 21 includes a mounting rod 212 and an abutment joint 213. A mounting through hole is provided on the mounting rod 212. One end of the mounting rod 212 is connected to the piston rod of the telescopic cylinder. A magnetic part is provided at the other end of the mounting rod 212. The magnetic part can be a magnet. The abutment joint 213 is made of ferromagnetic metal so that the abutment joint 213 can be magnetically fixed to the mounting rod 212 through the magnetic part. A clearance groove 214 is provided on the end surface of the abutment joint 213 facing the accommodating groove. Through the above design, workers can first select an abutment joint 213 of a suitable size according to the size of the bearing 4 to be press-fitted, so that the abutment joint 213 can abut against the outer ring of the bearing 4, and then directly magnetically fix the abutment joint 213 to the magnetic part of the mounting rod 212, so that the press-fitting assembly 2 can press-fit bearings 4 of different sizes.
[0055] Preferably, a limiting hole can be opened on the end face of the mounting rod 212 facing the receiving groove, and a limiting column 2131 matching the limiting hole can be set on the side of the abutment joint 213 facing away from the receiving groove. When the abutment joint 213 is magnetically fixed to the mounting rod 212, the limiting column 2131 can be inserted into the limiting hole and abut against the inner wall of the limiting hole, so that the abutment joint 213 can be limited in the horizontal direction through the cooperation of the limiting column 2131 and the limiting hole, thereby ensuring that the abutment joint 213 does not shake on the mounting rod 212.
[0056] See also Figure 3 and Figure 4The limiting sleeve 52 includes a connecting sleeve 521 and a limiting tube 522. A pair of waist-shaped holes are opened on the connecting sleeve 521 so that the connecting sleeve 521 can be connected to the mounting rod 212 via the limiting bolt 53. An external thread is arranged on the outer wall of the connecting sleeve 521; an internal thread matching the external nut is arranged at one side of the pipe opening of the limiting tube 522 and can be threadedly connected with the connecting tube; the other side of the pipe opening of the limiting tube 522 can be sleeved on the bearing 4, so that the outer ring of the bearing 4 abuts against the inner wall of the limiting tube 522.
[0057] Through the above design, workers can first select a limiting tube 522 with a suitable inner diameter according to the size of the bearing 4 to be pressed, so that the inner wall of the limiting tube 522 can fit with the outer ring of the bearing 4; then screw the limiting tube 522 with the connecting sleeve 521, so that the limiting sleeve 52 can cover bearings 4 of different sizes and make the outer ring of the bearing 4 abut against the inner wall of the limiting sleeve 52, so that the bearing limiting assembly 5 can limit bearings 4 of different sizes.
[0058] Based on the structure of the auxiliary locking device for the bearing 4 of the stamping pump, the second aspect of the present application further provides an application method of the auxiliary locking device for the bearing 4 of the stamping pump, which is implemented by using the auxiliary locking device for the bearing 4 of the stamping pump, and the method specifically includes:
[0059] Preliminary steps: first, select the matching abutment joint 213 and the stopper tube 522 according to the size of the bearing 4 to be press-fitted, and then install the abutment joint 213 and the stopper tube 522 on the press-fitting assembly 2;

[0061] Press-fitting steps: first drive the piston rod of the telescopic cylinder to extend from the cylinder body, so that the piston rod drives the press-fitting part 21 to approach and abut against the bearing 4. After the bearing 4 is pressed into the mounting hole 31, drive the piston rod of the telescopic cylinder to retract into the cylinder body, and remove the pump core 3 with the pressed bearing 4 from the receiving groove.
[0062] Since the application method of the auxiliary locking device of the bearing 4 of a stamping pump of the present application is implemented by the auxiliary locking device of the bearing 4 of a stamping pump mentioned above, it can also have all the technical effects of the auxiliary locking device of the bearing 4 of a stamping pump mentioned above. In particular, the worker can first install the abutment 213 and the limiting tube 522 of appropriate specifications on the auxiliary locking device of the bearing 4 of the stamping pump through the preparatory steps, and then put the pump core 3 and the bearing 4 in place through the workpiece placement steps, and finally complete the press-fitting of the bearing 4 through the pressing steps, so that the worker does not need to use a hammer or other knocking tools to knock the bearing 4 into the mounting hole 31, ensuring that the bearing 4 or the pump core 3 will not be damaged due to knocking, and the cooperation of the bearing limiting assembly 5 and the pressing part 21 can make it difficult for the bearing 4 to be deflected in the mounting hole 31, and the installation accuracy is high.
[0063] Specifically, the installation steps of the abutment joint 213 and the limiting tube 522 in the preparatory step are: first, the abutment joint 213 is magnetically fixed on the magnetic part of the mounting rod 212, and then the limiting tube 522 is sleeved on the mounting rod 212 and the limiting tube 522 is screwed to the connecting sleeve 521, so as to realize the installation of the abutment joint 213 and the limiting tube 522.
