DETAILED DESCRIPTION

[0028] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0030] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0031] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0032] At present, the processing of product polishing is only to fix the position of the product to facilitate the implementation of the polishing operation. However, not all products that need to be polished need to be fixed. Some products are equipped with side holes. These side holes can easily collapse due to improper operation during the polishing process, thereby reducing the quality rate of product polishing. Products with collapsed side holes cannot be used any more. Therefore, the cost of product polishing will also increase accordingly.

[0033] Based on this, the present application proposes a clamp that can protect the side holes of the product during the polishing process, improve the yield of the product after polishing, and reduce the cost of product polishing.

[0034] The following references Figure 1 and Figure 3 The clamper according to the embodiment of the present application is described.

[0035] It can be understood that the clamper of the embodiment of the present application includes: a clamping assembly, the clamping assembly includes a first connecting member 150, a clamping arm 100 and a pull rod 130, there are at least two clamping arms 100, the first connecting member 150 is provided with a groove, the clamping arm 100 is installed in the groove, the pull rod 130 can be movably passed through the first connecting member 150, the pull rod 130 is arranged between multiple clamping arms 100, and a protective column 110 is provided on the side of the clamping arm 100 away from the pull rod 130. The protective column 110 is used to engage with the side hole of the product, and the cross-sectional area of ​​the pull rod 130 at one end close to the clamping arm 100 is larger than the cross-sectional area of ​​the other end of the pull rod 130. The pull rod 130 is used to push the clamping arm 100 to engage with the product.

[0036] The beneficial effects of the clamp of the embodiment of the present application can be manifested as follows: by providing a protective column 110 with a shape similar to the side hole of the product, the protective column 110 can be tightly engaged with the side hole of the product, and by setting the cross-sectional area of ​​the pull rod 130 close to one end of the clamping arm 100 to be larger than the cross-sectional area of ​​the other end, the pull rod 130 will not separate from between the clamping arms 100 during the driving process, and will drive the various clamping arms 100 away from each other, so that each clamping arm 100 can clamp the product, and each clamping arm 100 can be engaged with the product to fix the product, which is convenient for processing the product, and the protective column 110 on the clamping arm 100 is engaged with the side hole of the product, thereby protecting the side hole and effectively preventing the side hole from collapsing.

[0037] For example, in some embodiments, reference Figure 3 and Figure 4, there are six clamping arms 100, and the pull rod 130 is movably arranged between the six clamping arms 100. The six clamping arms 100 are integrally sleeved on the pull rod 130. The first connecting piece 150 is provided with a groove, and the clamping arm 100 is installed in the groove through the third fastener 102, and the pull rod 130 is also movable relative to the first connecting piece 150. A protective column 110 is provided on the side of the top of the clamping arm 100 away from the pull rod 130. The cross-section of the protective column 110 is a profiling design of the side hole of the product, so that the protective column 110 can be tightly engaged with the side hole when the product is polished, thereby avoiding the collapse of the side hole. The end of the pull rod 130 close to the clamping arm 100 is in the shape of a circular cover, and its cross-sectional area is larger than the cross-sectional area of ​​the other end, so that the pull rod 130 will not fall out from between the clamping arms 100 during the pushing process, and the space enclosed by the clamping arm 100 is a funnel-shaped space, and the cross-sectional area of ​​the space is along The pull rod 130 gradually decreases in the direction away from the clamping arm 100, and when the pull rod 130 is driven away from the clamping arm 100, the circular cover surface will also move in the same direction along the inner wall of the clamping arm 100, and during the movement, the circular cover surface will provide the clamping arm 100 with a force to expand in the direction away from the pull rod 130. At this time, the product can be placed on each clamping arm 100, so that the top of the clamping arm 100 is tightly fitted with the inner wall of the product, and the protective column 110 on the clamping arm 100 is also tightly engaged with the side hole of the product. When the pull rod 130 is driven toward the direction close to the clamping arm 100, because the clamping arm 100 is arranged in the groove of the first connecting member 150, the first connecting member 150 will limit the clamping arm 100, thereby prompting the clamping arm 100 to have a tendency to shrink toward the side close to the pull rod 130, so that each clamping arm can jointly achieve the function of clamping the product.

[0038] It should be noted that the number of clamping arms 100 can also be three, four, and five. The shape of the pull rod 130 near one end of the clamping arm 100 can be a rectangular cover. The shape of the cross section of the protective column 110 is designed based on the imitation of the side hole of the product. Therefore, the shape of the cross section of the protective column 110 needs to be designed according to the side hole of the specific product.

[0039] It can be understood that the outer side wall of the top of the clamping arm 100 is in an arc shape.

[0040] For example, in some embodiments, reference Figure 5 The outer side walls of the tops of the six clamping arms 100 are arc-shaped. Before polishing the product, the clamping arms 100 will expand in the direction away from the pull rod 130. The outer side walls of the clamping arms 100 will fit tightly with the inner side walls of the product to fix the product and prevent the product from detaching and causing unnecessary losses.

[0041] It can be understood that the clamping assembly also includes an elastic assembly 190 and an adjustable fastener 180. The adjustable fastener 180 is arranged at the end of the pull rod 130 away from the clamping arm 100. The elastic assembly 190 is arranged on the pull rod 130. The elastic assembly 190 is arranged on the side of the adjustable fastener 180 close to the clamping arm 100. The elastic assembly 190 is connected to the adjustable fastener 180. The elastic assembly 190 and the adjustable fastener 180 are used to adjust the expansion degree of the clamping arm 100.

[0042] For example, in some embodiments, reference Figure 4 In this embodiment, the elastic component 190 is a spring, and the adjustable fastener 180 is a nut. The spring and the nut are sequentially sleeved on the end of the pull rod 130 away from the clamping arm 100, and the spring is connected to the side of the nut close to the clamping arm 100. When the nut is adjusted toward the direction close to the clamping arm 100, the spring is squeezed by the nut, and then the spring gives the nut a reaction force toward the direction of the pull rod 130 away from the clamping arm 100. The nut drives the pull rod 130 to move in the direction away from the clamping arm 100, and the pull rod 130 will push the clamping arm 100 to expand in the direction away from the pull rod 130, thereby realizing the adjustment of the expansion degree of the clamping arm 100.

[0043] It should be noted that the adjustable fastener 180 may also be a fixed tube structure that can be movably fixed to the pull rod 130, and the elastic component 190 may also be a structure such as a rebound rubber pad.

[0044] It is understandable that the clamping assembly further includes a pad 120 , which is disposed on the pull rod 130 , and an elastic assembly 190 is disposed between the pad 120 and the adjustable fastener 180 , and the pad 120 and the elastic assembly 190 are connected.

[0045] For example, in some embodiments, reference Figure 3 and Figure 4 The pad 120 is sleeved on the pull rod 130, and the pad 120 and the pull rod 130 are connected by a first connecting member 150 that is movably sleeved on the pull rod 130. The pad 120 is arranged on the side of the elastic component 190 close to the clamping arm 100 so as to reduce the required length of the elastic component 190, thereby reducing maintenance costs.

[0046] It can be understood that the clamp also includes a shell 170, and the clamping assembly also includes a second connecting member 160, the second connecting member 160 is sleeved on the pull rod 130, the second connecting member 160 is connected to the side of the pad 120 close to the clamping arm 100, the second connecting member 160 and the shell 170 are connected by a first fastener 161, the end of the pull rod 130 away from the clamping arm 100 is arranged in the shell 170, and the bottom of the shell 170 is provided with a through opening 171.

[0047] For example, in some embodiments, reference Figure 2 and Figure 3 The second connecting member 160 is sleeved on the pull rod 130, and the first connecting member 150 is movably sleeved on the pull rod 130. The second connecting member 160 and the pull rod 130 are connected by the first connecting member 150. The end of the pull rod 130 away from the clamping arm 100 is arranged in the shell 170. At the same time, the adjustable fastener 180, the elastic component 190 and the pad 120 are all arranged in the shell 170 with the pull rod 130 to protect the parts. The shell 170 is cylindrical as a whole, which is convenient for the operator to hold it in hand. The shell 170 and the second connecting member 160 are connected by the first fastener 161. In this embodiment, the first fastener 161 is a screw. There is a certain space between the pull rod 130 and the bottom of the shell 170, and a through hole 171 is provided at the bottom of the shell 170 so that the driving device can enter the shell 170 through the through hole 171 to drive the pull rod 130.

[0048] It is understandable that a protective cover 140 is provided on the top of the clamping arm 100 , and the protective cover 140 is engaged and connected to the first connecting member 150 .

[0049] For example, in some embodiments, reference Figure 1 and Figure 3 The protective cover 140 is sleeved on the top of the clamping arm 100, and the first connecting member 150 is provided with a connecting groove. The protective cover 140 is snap-fitted and attached to the connecting groove. During the product polishing operation, the inner wall of the product fits tightly with the protective cover 140, which can effectively prevent the inner arc angle size of the product from changing, improve the quality rate of the product after polishing, and reduce the cost of product polishing.

[0050] It should be noted that the protective cover 140 can be made of materials such as tungsten steel, aluminum, and copper.

[0051] It is understandable that the protective sleeve 140 is a tungsten steel protective sleeve.

[0052] For example, in some embodiments, reference Figure 1 and Figure 3 The protective cover 140 mounted on the clamping arm 100 is made of tungsten steel, which makes the protective cover 140 more durable, reduces the frequency of replacing the protective cover 140, and reduces the cost.

[0053] It can be understood that the protection column 110 is detachably mounted on the side wall of the clamping arm 100 via the second fastener 101 .

[0054] For example, in some embodiments, reference Figure 5The side wall of the clamping arm 100 is provided with a mounting hole 103, and the top of the clamping wall is provided with a fixing hole. The protective column 110 is installed on the side wall of the clamping arm 100 through the mounting hole 103. The second fastener 101 passes through the fixing hole to detachably install the protective column 110 in the mounting hole 103, so that the protective column 110 with different cross-sectional shapes can be replaced according to product requirements to achieve adaptation to multiple scenarios. The second fastener 101 in this embodiment is a screw.

[0055] It should be noted that the second fastener 101 may also be a rivet structure.

[0056] It is understandable that an observation hole 131 is provided at the top of the pull rod 130 close to the clamping arm 100 , and the observation hole 131 corresponds to the protection column 110 .

[0057] For example, in some embodiments, reference Figure 4 The top surface of the pull rod 130 near one end of the clamping arm 100 is a circular cover plate, on which a rectangular observation hole 131 is provided. Directly below the observation hole 131 is the protective column 110, so that the operator can observe the fixing status of the protective column 110 through the observation hole 131.

[0058] It should be noted that the observation hole 131 may also be provided on the top or side of the clamping arm 100 .

[0059] The polishing device according to the embodiment of the second aspect of the application includes the clamper according to the embodiment of the first aspect of the application.

[0060] The clamping device according to the embodiment of the present application is provided with a protective column 110 having a shape similar to the side hole of the product, so that the protective column 110 can be tightly engaged with the side hole of the product. By setting the cross-sectional area of ​​the pull rod 130 close to one end of the clamping arm 100 to be larger than the cross-sectional area of ​​the other end, the pull rod 130 will not separate from the clamping arms 100 during the driving process, and will drive each clamping arm 100 away from each other, so that each clamping arm 100 can clamp the product, and each clamping arm 100 can be engaged with the product to fix the product, which is convenient for processing the product. The protective column 110 on the clamping arm 100 is engaged with the side hole of the product, thereby protecting the side hole and effectively preventing the side hole from collapsing. The arc-shaped outer wall of the top of the clamping arm 100 and the protective cover 140 can avoid the problem of poor inner arc angle size of the product, thereby improving the entire polishing process, so as to improve the product polishing pass rate while reducing the cost of product polishing.

[0061] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
