BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1It is a structural schematic diagram of the portable bearing rolling element removal device of the present invention;
[0016] Figure 2 for Figure 1 Enlarged view of part A in the middle. DETAILED DESCRIPTION
[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0018] Reference Figures 1 to 2 As shown, a portable bearing rolling element removal device of this embodiment includes a shell 1, an adsorption head 2 and a push-pull rod 3. The shell 1 is hollow cylindrical, and the adsorption head 2 is arranged in the middle of the shell 1. The push-pull rod 3 penetrates from one end of the shell 1 and is linked with the adsorption head 2 to control the adsorption head 2 to adsorb or release the rolling element. A push rod 4 is provided on the side of the outer wall of the shell 1 facing away from the adsorption head 2, and a push seat 5 is connected to the end of the push rod 4 facing away from the shell 1. A positioning fixture 6 for positioning the bearing is fixed on the push seat 5 facing the side of the shell 1, and the push seat 5 faces away from the positioning fixture 6. A pressing portion 53 for manual pressing is provided on one side, and the pushing rod 4 is a telescopic rod structure. The shell 1 in this embodiment adopts a hollow setting, and an adsorption rubber plug is correspondingly provided on the adsorption head 2, and a piston is provided at the end of the push-pull rod 3. In this way, the air pressure in the shell 1 is changed by moving the push-pull rod 3, and the negative pressure generated by the adsorption head 2 is further changed, so as to control the adsorption head 2 to absorb or release the bearing rolling element. By setting the pushing seat 5, the positioning fixture 6 and the pressing portion 53, it is possible to effectively provide a component for people to press, thereby achieving a portable effect, and no additional power source is required.
[0019] As an improved specific embodiment, the positioning fixture 6 includes a left clamping plate 61 and a right clamping plate 62 and a driving screw 63. The left clamping plate 61 and the right clamping plate 62 can be slidably set on the lower side of the pushing seat 5 to slide relative to or away from each other. The driving screw 63 can be rotatably passed through the right clamping plate 62 and the left clamping plate 61, and threadedly connected with the right clamping plate 62 and the left clamping plate 61. A splicing step is provided on the opposite side of the left clamping plate 61 and the right clamping plate 62 near the lower side. The two splicing steps can be spliced together to form a groove for the outer ring of the bearing to be embedded. Through the setting of the above structure, the rotation of the driving screw 63 can be used to control the distance between the left clamping plate 61 and the right clamping plate 62, thereby achieving the effect of the left clamping plate 61 and the right clamping plate 62 cooperating with each other to clamp or release the outer ring of the bearing, and it can also be applicable to bearings of different thicknesses.
[0020] As an improved specific implementation method, the driving screw 63 is coaxially sleeved with a driving wheel 631 at one end away from the right splint 62, and the upper side of the pushing seat 5 is rotatably provided with a power handwheel 54. The power handwheel 54 and the driving wheel 631 are linked by a belt. Through the setting of the power handwheel 54, the distance between the left splint 61 and the right splint 62 can be effectively adjusted by turning the power handwheel 54 with fingers, so no additional application tools are required.
[0021] As a specific embodiment of the improvement, a support rod 11 is provided on the lower side of the shell 1, and a support plate 12 for being placed on the external ground is coaxially fixed to the lower end of the support rod 11. The position of the support rod 11 corresponds to the position of the push rod 4 up and down. By using the setting of the support rod 11, people can press down from top to bottom during the dismantling process, which can greatly increase the dismantling force.
[0022] As an improved specific embodiment, a linkage rod 51 is provided on the side of the pushing seat 5, and a hinge seat 13 is provided on the end of the push-pull rod 3 and the end of the shell 1. The linkage rod 51 is hinged with two driven rods 52 at one end away from the pushing seat 5, and the two driven rods 52 are hinged to the hinge seat 13 on the end of the push-pull rod 3 and the hinge seat 13 on the end of the shell 1 at one end facing away from the linkage rod 51. The above-mentioned structure is set up to achieve synchronous sliding of the push-pull rod 3 during the downward pressing process, further increasing the suction force of the adsorption head 2, so that the rolling body can be better removed from the retaining frame.
[0023] As a specific embodiment of the improvement, a support connecting rod 111, a support following rod 112 and a support hinge seat 113 are provided on the side wall of the support rod 11. The support connecting rod 111, the support following rod 112 and the support hinge seat 113 are mirror images of each other with the linkage rod 51, the driven rod 52 and the hinge seat 13 with the push-pull rod 3 as the mirror axis. Through the arrangement of the above structure, the linkage rod 51, the driven rod 52 and the hinge seat 13 can cooperate with each other with the push-pull rod 3, so that the force on the push-pull rod 3 in the upper and lower directions is equal, thereby avoiding the problem of offset deformation of the push-pull rod 3 due to uneven force on the upper and lower sides.
[0024] As an improved specific embodiment, the push rod 4 includes a sleeve rod 41, a through rod 42 and a fixed ring sleeve 43. The fixed ring sleeve 43 is detachably sleeved on the outer shell 1. The lower end of the through rod 42 is fixed on the fixed ring sleeve 43. The upper end of the sleeve rod 41 is fixed on the lower side surface of the push seat 5. The upper end of the through rod 42 can be slidably inserted into the sleeve rod 41. Through the arrangement of the above structure, the retractable structure of the push rod 4 can be simply and effectively realized.
[0025] As an improved specific embodiment, a power bolt 7 is rotatably provided on the upper side surface of the pushing seat 5 relative to the position of the sleeve rod 41. The lower end of the power bolt 7 is inserted into the sleeve rod 41 and is threadedly connected to the upper end of the penetration rod 42. Through the setting of the power bolt 7, when the human strength is small and it is difficult to press the outer ring, the threaded advancement effect can be achieved by rotating the power bolt 7, so that the outer ring of the bearing can be pushed well, and the overall process is smoother and more reliable.
[0026] As an improved specific embodiment, a sliding groove 421 is opened in the penetrating rod 42, and the two ends of the sliding groove 421 are closed. A sliding block 422 that can be raised and lowered is provided therein. The lower end of the sliding block 422 is connected to the lower end of the sliding groove 421 by a spring. The lower end of the power bolt 7 passes through the sleeve rod 41 and then enters the penetrating rod 42, and is threadedly connected to the sliding block 422. Through the setting of the sliding block 422, it is possible to effectively provide a threaded connection base that cooperates with the power bolt 7. At the same time, when there is no need to thread forward through the power bolt 7, it is only necessary to directly press the pushing seat 5, and the sliding block 422 will slide downward, thereby achieving a quick disassembly effect.
[0027] As an improved specific embodiment, the upper end of the power bolt 7 is coaxially sleeved with a gear, the pressing portion 53 is bowl-shaped, and is rotatably arranged on the push seat 5, and a gear ring is sleeved on the outer wall of the pressing portion 53, and the gear ring is engaged with the gear. Through the setting of the gear ring, the gear can be driven to rotate by rotating the pressing portion 53, which makes it convenient for people to drive the power bolt 7.
[0028] In summary, the dismantling device of this embodiment can provide a structure for manual operation through the coordinated arrangement of the pushing seat 5, the pushing rod 4, the pressing part 53 and the positioning clamp 6, without the need for an additional power source, thus achieving great convenience.
