[0002] In industrial production and daily life, when picking up certain objects, sometimes it is inconvenient to directly contact their outer surfaces, and only the method of supporting their inner walls from the inside can be adopted for clamping. For some objects, due to reasons such as thin wall thickness, weak strength, or easy damage to the inner surface, metal or other rigid fixtures cannot be used for inner support clamping, otherwise the objects may be damaged. Or for some objects, the internal space is small or the contour is complex. Customizing special rigid fixtures has a high cost and cannot be applied to other objects at the same time. And if the design is improper, it may also cause poor clamping stability and easy detachment. Therefore, a technology is needed to provide inner support clamping in various industrial productions and daily life, or to internally support and fix certain objects.

[0003] After retrieval, the Chinese patent publication number: CN221211404U discloses a stator type fixture. This fixture controls the movable mounting ring to approach the fixed mounting ring through a driving component, so that one end of multiple clamping plates away from the main shaft 1 fits on the inner side of the stator, and only applies a vertical force to the inner side of the stator, avoiding the axial displacement of the stator, and avoiding the problems of affecting the machining accuracy, resulting in defective products, or even scrapping.

[0004] Although the above fixture can avoid the axial displacement of a regular bearing inner ring, it still lacks a certain stability for some elliptical bearing inner rings and cannot achieve complete fitting during use. Therefore, an inner support type fixture suitable for a bearing inner ring is proposed to solve the above problems. Summary of the Utility Model

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: an inner support type clamp suitable for the inner ring of a bearing, comprising a clamp body 1. The clamp body 1 is a stator inner support type clamp disclosed in the Chinese patent application number "CN221211404U", which is a prior art and will not be described in detail here. A support plate 2 is provided at the end of the X-shaped movable mechanism of the clamp body 1. The support plate 2 mainly serves to receive the adjustment component 3. A groove 21 is provided on the side wall of the support plate 2. The groove 21 is used to place a bidirectional screw rod and a slider 31, and guides the slider 31.

[0032] Reference Figure 1 - Figure 2, an adjusting component 3 is arranged inside the groove 21. The adjusting component 3 is used to adjust the relative distance between the support plate 2 and the mounting plate 35. The adjusting component 3 includes a slider 31. The slider 31 is slidably connected inside the groove 21. There are two groups of sliders 31 arranged symmetrically. A bidirectional threaded rod 32 is threadedly connected between the two groups of sliders 31. A braking wheel 33 is fixedly connected to the end of the bidirectional threaded rod 32. The bidirectional threaded rod 32 penetrates and is rotatably connected to the side wall of the support plate 2. The part of the bidirectional threaded rod 32 penetrating the support plate 2 is not provided with threads. By rotating the braking wheel 33, the bidirectional threaded rod 32 rotates forward or backward, so that the two groups of sliders 31 move horizontally in the groove 21 to adjust the distance between the two groups of sliders 31.

[0033] Refer to Figure 1 - Figure 2 , a traction rod 34 is hinged to the side wall of the slider 31. One end of the traction rod 34 away from the slider 31 is hinged to a mounting plate 35. By adjusting the distance between the two groups of sliders 31 in the groove 21, one end of the traction rod 34 moves along with the movement of the slider 31, and the inclination angle of the traction rod 34 changes, thereby adjusting the distance between the support plate 2 and the mounting plate 35, and being able to fully fit the elliptical inner ring of the bearing.

[0034] Refer to Figure 2 - Figure 3 , a buffer component 4 is arranged on the side wall of the mounting plate 35, which plays a buffering role when the fixture fixes the bearing. The buffer component 4 includes a telescopic rod 41. The telescopic rod 41 is fixedly connected to the side wall of the mounting plate 35. A clamping plate 5 is fixedly connected to the end of the telescopic rod 41. There are three groups of mounting plates 35 and clamping plates 5, and the three groups of mounting plates 35 and clamping plates 5 are arranged in a circular array. Since the telescopic rod 41 is fixedly connected between the mounting plate 35 and the clamping plate 5, it plays a role in stabilizing the clamping plate 5, so that the clamping plate 5 is on the same horizontal line as the mounting plate 35 during the movement process to avoid deviation. A bottom plate 51 is fixedly connected to the bottom end of the outer wall of the clamping plate 5. A raised part is formed on the side wall of the clamping plate 5 through the bottom plate 51, and the bearing can be placed on the fixture for clamping and fixing.

[0035] Refer to Figure 2 - Figure 3, a rubber anti-slip pad is provided on the surface of one end of the clamping plate 5 away from the telescopic rod 41. The rubber anti-slip pad is used to increase the mutual friction between the clamping plate 5 and the inner ring of the bearing, making it more stable and avoiding hard contact between the inner ring of the bearing and the clamping plate 5. One end of the clamping plate 5 away from the telescopic rod 41 is set to be arc-shaped, and the arc-shaped clamping plate 5 fits better with the inner ring of the bearing. The clamping plate 5 and the mounting plate 35 are elastically connected by a spring 42. The spring 42 is sleeved on the outer wall of the telescopic rod 41. When the clamping plate 5 contacts the inner wall of the bearing and applies pressure, the spring 42 is compressed by the force to buffer the supporting force received by the inner ring of the bearing and avoid damage to the inner ring of the bearing caused by excessive pressure.

[0036] Working principle: When it is necessary to clamp and fix the elliptical inner ring of the bearing, the operator rotates the brake wheel 33, driving the rotation of the double-threaded rod 32. Since the double-threaded rod 32 is threadedly connected to the two groups of sliders 31 and the thread directions are opposite, as the double-threaded rod 32 rotates forward or backward, the two groups of sliders 31 will move towards or away from each other horizontally in the groove 21 accordingly.

[0037] As the position of the slider 31 is adjusted, one end of the traction rod 34 hinged to it will also move accordingly, resulting in a change in the inclination angle of the traction rod 34, and then causing an adjustment in the distance between the mounting plate 35 and the support plate 2, enabling the entire fixture to adaptively adjust according to the specific shape and size of the inner ring of the bearing, ensuring that the clamping plate 5 can fully and evenly fit the inner wall of the inner ring of the bearing.

[0038] During the process of the clamping plate 5 gradually approaching and contacting the inner ring of the bearing, the rubber anti-slip pad first contacts the surface of the inner ring of the bearing, effectively increasing the friction between the two and preventing the inner ring of the bearing from sliding or falling off during the clamping process. At the same time, since the clamping plate 5 and the mounting plate 35 are elastically connected by the spring 42, when the clamping plate 5 applies pressure to the inner ring of the bearing, the spring 42 will be compressed accordingly, thus playing a buffering role and avoiding direct hard impact on the inner ring of the bearing, protecting the inner ring of the bearing from damage.

[0039] In addition, the telescopic rod 41 not only ensures the stability of the clamping plate 5 during the movement, keeping it on the same horizontal line as the mounting plate 35, but also provides a stable support point for the clamping plate 5 through its fixed connection structure, making the entire clamping process more stable and reliable.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
