[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. Meanwhile, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0032] The embodiment of the present application provides a clamping machine, which includes a fixed frame, a lifting frame and a slider device, wherein the fixed frame has a slide rail extending in the height direction, the lifting frame is slidably arranged on the fixed frame through the slider device, and the lifting frame is used to install a clamping arm to clamp and drive the goods to move in the height direction.

[0033] Specifically, the lifting frame is driven by a motor to rise and fall along the slide rail of the fixed frame. Based on the slider device provided in some embodiments of the present application (the specific structure of the slider device will be described in detail below), the smoothness of the lifting frame can be improved, and aging wear can be reduced. At the same time, the shaking of the slider device during the sliding process can be reduced, and the noise during operation can be reduced, thereby ensuring the long-term stable and efficient operation of the equipment and increasing its service life.

[0034] refer to Figures 1 to 4 The slider device includes a base 1, a slider 2 and a rotating member 3. The slider 2 is arranged on the base 1. The slider 2 includes a bottom wall 22 and two side walls 23 arranged at both ends of the bottom wall 22 along the first direction X. The bottom wall 22 and the two side walls 23 together form a slide groove 21. After the slider device is installed on the slide rail, the first direction X is consistent with the width direction of the slide rail. The slide groove 21 is used to match the slide rail in a concave and convex manner so that the slider 2 matches the slide rail through the slide groove 21. The rotating member 3 is arranged in the slide groove 21 and is rotatable along its own axis. The axis of the rotating member 3 is consistent with the first direction X, and in the process of the slider device sliding relative to the slide rail, the circumferential surface of the rotating member 3 is in rolling contact with the slide rail.

[0035] Specifically, the surface of the slide rail that is used to cooperate with the bottom wall 22 of the slider 2 is called the upper surface of the slide rail, or in other words, the surface formed by the length and width of the slide rail. The existing solution usually makes the upper surface of the slide rail directly contact with the bottom wall 22. During the sliding process of the slider, the bottom wall 22 and the upper surface of the slide rail form sliding friction, which causes the slide to be easily worn and brings more inconvenience.

[0036] The present application changes the contact mode between the slider 2 and the upper surface of the slide rail from sliding friction to rolling friction, thereby reducing the friction loss of the slider, improving the smoothness of the slider device sliding on the slide rail, reducing the risk of unstable sliding process due to slider wear, and improving sliding stability.

[0037] In some embodiments, the two side walls 23 have inner sides facing each other. The inner sides of the two side walls 23 are respectively slidably matched with the slide rails.

[0038] Specifically, the surface formed by the length and height of the slide rail is called the side surface of the slide rail. The side surface of the slide rail is used to cooperate with the side wall 23 of the slider 2. During the sliding process of the slider 2, there is sliding friction between the side surface of the slide rail and the inner surface of the side wall 23, but the sliding friction force is small in value because the slider 2 is mainly subjected to the first force in the height direction and the second force in the depth direction of the slide groove 21. The first force drives the slider 2 to move in the height direction, and the second force is used to drive the bottom wall 23 of the slider 2 to be in close contact with the steering member 3. In other words, the side wall 23 plays a more limiting role to ensure that the slider 2 does not separate from the slide rail.

[0039] refer to Figure 6 In some embodiments, the slider 2 further includes a first through hole 24 penetrating the side wall 23 in the first direction X. The slider device further includes a rotating shaft 4. The rotating shaft 4 passes through the first through holes 24 of the two side walls 23 respectively. The rotating member 3 is rotatably disposed on the rotating shaft 4.

[0040] Specifically, the opening positions of the first through holes 24 on the two side walls 23 are aligned, so that the rotating shaft 4 can pass through the first through holes 24 of the two side walls 23 relatively smoothly. And the first through hole 24 is opened at a position of the side wall 23 close to the bottom wall 22. That is, the distance from the top of the groove 21 to the first through hole 24 is greater than the distance from the bottom of the groove 21 to the first through hole 24, so that the rotating member 3 can be located at a position closer to the bottom of the groove 21, leaving space for installing the slide rail.

[0041] In some embodiments, two first through holes 24 are spaced apart on each side wall 23 , and the slider device includes two rotating shafts 4 and two rotating members 3 . The two rotating shafts 4 pass through the two first through holes 24 respectively, and the two rotating members 3 are respectively disposed on the two rotating shafts 4 .

[0042] In some embodiments, the rotating member 3 includes a bearing.

[0043] In some embodiments, the bearing may be a deep groove ball bearing. Figure 1 In some embodiments, a sleeve 5 is further included. The rotating shaft 4 includes a stepped shaft. One axial side of the inner ring of the bearing abuts against the step surface of the stepped shaft. The sleeve 5 is sleeved on the rotating shaft 4, and the axial ends of the sleeve 5 abut against the other axial side of the inner ring of the bearing and the inner side surface of the side wall 23, respectively, to limit the axial position of the bearing. The sleeve 5 can improve the position stability of the bearing.

[0044] refer to Figure 7 and 8In some embodiments, the stepped shaft includes a first shaft section 41, a second shaft section 42, and a third shaft section 43, the shaft diameters of which increase in sequence. A first step surface 44 is formed at the connection between the first shaft section 41 and the second shaft section 42. A second step surface 45 is formed at the connection between the second shaft section 42 and the third shaft section 43. The first step surface 44 is used to abut against the inner ring of the bearing. The first shaft section 41 extends through the first through hole 24 of one of the two side walls 23. The third shaft section 43 is located outside the outer side surface of the other of the two side walls 23. The second step surface 45 is used to limit the outer side surface of the other of the two side walls (23).

[0045] Specifically, the rotating shaft 4 is arranged as a stepped shaft, so that the step surface of the stepped shaft itself can not only axially limit the bearing, but also axially limit the slider 2. For example, the second step surface 45 is directly or indirectly abutted against the outer surface of one of the two side walls of the slider 2, thereby realizing the axial limitation of the slider 2. Such a setting can simplify the structure without the need to set up additional limiting structural parts, which is convenient for disassembly, maintenance and replacement of parts of the slider device.

[0046] refer to Figure 6 In some embodiments, the slider 2 further includes a recessed area 25 disposed on the bottom wall 22. At least a portion of the circumferential surface of the rotating member 3 enters the bottom wall 22 through the recessed area 25. The top of the rotating member 3 is lower than the top of the slide groove 21 in the height direction.

[0047] This arrangement allows the shaft 4 to be closer to the bottom of the slide groove 21 in the slide groove 21, and the recessed area 25 provides space for the sunken arrangement of the rotating member 3. It can also increase the distance between the top of the rotating member 3 and the top of the slide groove 21, making it easier to install the slide rail and improving the sliding stability after assembly with the slide rail.

[0048] In order to further bring the rotating shaft 4 closer to the bottom of the chute 21, refer to Figure 5 and 6 In some embodiments, the recessed area 25 penetrates the bottom wall 22 in the thickness direction of the bottom wall 22. The base 1 includes a base body 11 and a base through hole 12 penetrating the base body 11 in the thickness direction of the base body 11. The base through hole 12 and the recessed area 25 correspond in position. At least part of the circumferential surface of the rotating member 3 passes through the recessed area 25 and enters the base through hole 12.

[0049] It should be understood that in the embodiment where two rotating members 3 are provided, two recessed areas 25 and two base through holes 12 are also provided accordingly.

[0050] refer to Figure 5In some embodiments, the base 1 further includes a lifting frame mounting hole 14 disposed on the base body 11, and the lifting frame mounting hole 14 is used to connect the base 1 and the lifting frame. More specifically, the base 1 includes four lifting frame mounting holes 14 symmetrically distributed around the center of the base body 11, so that the connection stability with the lifting frame can be improved.

[0051] refer to Figure 2 and 6 In some embodiments, the slider 2 further includes a lubrication hole 26 and a lubrication groove 27. The lubrication groove 27 extends on the inner side of the side wall 23. One end of the lubrication hole 26 is located on the outer side of the side wall 23. The other end of the lubrication hole 26 penetrates the side wall 23 in the first direction X and extends to the lubrication groove 27. The lubrication hole 26 is used to inject lubricating liquid into the lubrication groove 27.

[0052] Specifically, the lubrication groove 27 extends in the second direction Y (after the slider device is installed on the slide rail, the second direction Y is consistent with the length direction of the slide rail) and passes through the first through hole 24. The lubricating liquid injected through the lubrication hole 26 is distributed in the entire lubrication groove 27 to provide lubrication for the rotation of the bearing, thereby improving the stability of the slider device 2 during operation and improving the operating efficiency of the clamping machine. Figure 1 and 9 In some embodiments, the slider device further includes a first position-limiting member 6. The first position-limiting member 6 abuts against the slider 2 from both sides of the slider 2 in the first direction X to limit the slider 2.

[0053] The first position-limiting member 6 includes a position-limiting main body 61 and a position-limiting mounting portion 62. The position-limiting mounting portion 62 is arranged at the bottom side of the position-limiting main body 61. The size of the position-limiting main body 61 along the first direction X is larger than the size of the position-limiting mounting portion 62 along the first direction X, so that the profile of the first position-limiting member 6 is T-shaped. The base 1 includes a position-limiting member mounting hole 13 arranged on the base body 1. The position-limiting member mounting hole 13 is adapted in shape to the position-limiting mounting portion 62 and is used for plugging and matching with the position-limiting mounting portion 62 (it can also be welded after plugging to improve the connection stability) to achieve the fixation of the first position-limiting member 6. The size of the position-limiting main body 61 along the first direction X is substantially equal to the size of the side wall 23 of the slider 2 along the first direction X, so as to play a better role in limiting.

[0054] Furthermore, the first limiting member 6 further includes a limiting through hole 63. The limiting through hole 63 penetrates the limiting main body 61 in the first direction X, and the limiting through hole 63 is aligned with the first through hole 24, so that the first shaft section 41 of the rotating shaft 4 passes through the first through hole 24 and then continues to pass through the limiting through hole 63. One end of the first shaft section 41 passing through the limiting through hole 63 can be locked by a locking member 8 to limit and fix the rotating shaft 4 in the axial direction.

[0055] In some embodiments, the locking member 8 comprises a snap spring.

[0056] refer to Figure 1 and 2 In some embodiments, the slider device further includes a second stopper 7. The second stopper 7 abuts against the slider 2 from both sides of the slider 2 in the second direction Y to limit the slider 2. After the slider device is installed on the slide rail, the second direction Y is consistent with the length direction of the slide rail.

[0057] Specifically, the second limiting member 7 is respectively connected to the two ends of the first limiting member 6 along the second direction Y, and a rectangular area 6 for arranging the slider 2 is defined on the base 1, and the second limiting member 7 is in contact with the end surfaces of the two side walls 23 of the slider 2 along the second direction Y and the end surface of the bottom wall 22 along the second direction Y, so that the slider 2 is limited in both the first direction X and the second direction Y, thereby improving the stability of the slider device during the sliding process.

[0058] refer to Fig. 9 In some embodiments, the first position-limiting member 6 further includes a first mounting hole 64 disposed on the end surface of the position-limiting body 61 along the second direction Y, and a second mounting hole is disposed at a corresponding position of the second position-limiting member 7, and the second position-limiting member 7 is connected to the first position-limiting member 6 by arranging a connecting member passing through the first mounting hole 64 and the second mounting hole. The connecting member includes a bolt or a screw.

[0059] In some embodiments, the cross section of the second position-limiting member 7 is in a concave shape, so as to leave a space for installing the slide rail at the end of the slider 2 along the second direction Y. And the cross section of the second position-limiting member 7 is set to be in a concave shape, which can be adapted to the shape of the slider 2 and improve the limiting effect on the slider 2.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
