[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0034] Example 1
[0035] The inventors of this application discovered in their research that different sizes and shapes of workpieces require different fixtures. Especially when processing small batches of workpieces with special shapes, it is necessary to constantly change fixtures, resulting in excessively long processing times, high processing costs, and a cumbersome process. In related technologies, when processing workpieces with special shapes, such as polygonal or unilateral irregular shapes, it is difficult to position and clamp the workpiece during processing due to its irregular shape. This can lead to loosening or displacement of the workpiece during clamping, making workpiece processing inconvenient and affecting processing efficiency.
[0036] refer to Figure 1 As shown, an embodiment of this application provides a clamping device 100 for clamping a workpiece for positioning processing. The clamping device 100 includes a base 110, a first clamping assembly 120, a second clamping assembly 130, and an adjusting member 140.
[0037] Specifically, in combination Figure 2 and Figure 3 As shown, the base 110 is provided with a guide rail 111. The first clamping assembly 120 includes a first clamping member 121 and a plurality of first movable positioning members 122. The first clamping member 121 is fixedly installed at one end of the base 110, and each of the first movable positioning members 122 is movably connected to one side of the first clamping member 121. The second clamping assembly 130 includes a second clamping member 131 and a plurality of second movable positioning members 132. The second clamping member 131 is slidably connected to the base 110 through the guide rail 111, and each of the second movable positioning members 132 is movably connected to one side of the second clamping member 131. The first movable positioning members 122 and the second movable positioning members 132 are arranged opposite to each other, and the workpiece is clamped by the first movable positioning members 122 and the second movable positioning members 132 to facilitate the worker's processing of the workpiece.
[0038] In this embodiment, the adjusting member 140 is movably connected to the second clamping member 131, so that the adjusting member 140 drives the second clamping assembly 130 to move relative to each other. Correspondingly, the base 110 of the clamping device 100 is provided with a guide rail 111. The adjusting member 140 drives the second clamping member 131 to move relative to the first clamping member 121 on the guide rail 111, so that the workpiece is placed between the first clamping assembly 120 and the second clamping assembly 130. The first movable positioning member 122 and the second movable positioning member 132 can move relative to each other to achieve the purpose of contacting and clamping the workpiece, so as to match the shape and size of the workpiece, reduce the situation of the workpiece loosening or sliding, and have a better clamping effect for workpieces such as irregular workpieces, thereby improving the reliability and stability of the clamping device 100 in the workpiece clamping process.
[0039] It is understandable that, such as Figure 1 As shown, multiple first movable positioning elements 122 and multiple second movable positioning elements 132 work together to clamp and position the workpiece. After the first clamping element 121 and the second clamping element 131 are relatively positioned, since the multiple first movable positioning elements 122 and the multiple second movable positioning elements 132 are relatively movable, they have a large adjustment range. This allows the first movable positioning elements 122 and the second movable positioning elements 132 to form a contouring structure corresponding to the shape of the workpiece. This further avoids the situation where the clamping force is insufficient and the workpiece loosens due to the special shape or size of the workpiece. The workpiece is contacted and clamped according to its shape and size to adapt to workpieces of different shapes and sizes.
[0040] It should be noted that the reference Figures 1 to 4 As shown, the clamping device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is the length direction of the clamping device 100, the second direction Y is the width direction of the clamping device 100, and the third direction Z is the height direction of the clamping device 100.
[0041] In one embodiment, alternatively, referencing Figure 1 As shown, the adjusting member 140 drives the second clamping member 131 to move relative to each other on the guide rail 111 along the first direction X. That is, the adjusting member 140 drives the second clamping member 131 to move relative to each other on the guide rail 111 along the length direction of the clamping device 100, so as to adjust the relative distance between the second clamping member 131 and the first clamping member 121, thereby making the first movable positioning member 122 on the first clamping member 121 and the second movable positioning member 132 on the second clamping member 131 contact and abut against the workpiece respectively. The adjusting member 140 can adjust and lock the position of the second clamping member 131.
[0042] Optionally, combined Figure 2 and Figure 3 As shown, a plurality of first movable positioning members 122 are arranged parallel to each other along the first direction X, and a plurality of second movable positioning members 132 are arranged parallel to each other along the first direction X. Correspondingly, a plurality of first movable positioning members 122 are arranged parallel to each other along the length direction of the clamping device 100, and a plurality of second movable positioning members 132 are arranged parallel to each other along the length direction of the clamping device 100. The first movable positioning members 122 and the second movable positioning members 132 are arranged opposite to each other, and the first movable positioning members 122 and the second movable positioning members 132 respectively clamp and position the opposite sides of the workpiece.
[0043] In one embodiment, alternatively, referencing Figure 3 and Figure 4As shown, both the first clamping member 121 and the second clamping member 131 are provided with a plurality of mounting slots 123. Each of the first movable positioning members 122 corresponds to one mounting slot 123, and each of the second movable positioning members 132 corresponds to one mounting slot 123. The first movable positioning member 122 is installed in the mounting slot 123, and the second movable positioning member 132 is installed in the mounting slot 123, so that both the first movable positioning member 122 and the second movable positioning member 132 can move relative to each other.
[0044] Optionally, combined Figure 4 and Figure 5 As shown, both the first movable positioning member 122 and the second movable positioning member 132 include an elastic member 124 and a fixing rod 125. The elastic member 124 is disposed in the mounting groove 123, and the fixing rod 125 is inserted into the mounting groove 123. One end of the fixing rod 125 is connected to the elastic member 124, and the end of the fixing rod 125 away from the elastic member 124 extends out of the groove of the mounting groove 123. In other words, when the workpiece is contacted and clamped by the first movable positioning member 122 and the second movable positioning member 132, the relative position of the fixing rod 125 changes through the elastic member 124. By having multiple first movable positioning members 122 and multiple second movable positioning members 132 together cover the workpiece, the first clamping member 121 and the second clamping member 131 can maintain relative positioning during the workpiece clamping process.
[0045] In summary, the base 110 of the clamping device 100 is provided with a guide rail 111. The adjusting member 140 drives the second clamping member 131 to move relative to the first clamping member 121 on the guide rail 111, so that the workpiece is placed between the first clamping component 120 and the second clamping component 130. The workpiece is clamped by the first movable positioning member 122 and the second movable positioning member 132, so that the operator can process the workpiece. The first movable positioning member 122 and the second movable positioning member 132 can move relative to each other to achieve the purpose of contacting and clamping the workpiece, so as to match the shape and size of the workpiece, reduce the possibility of the workpiece loosening or sliding. It has a better clamping effect on workpieces such as irregularly shaped workpieces, improves the reliability and stability of the clamping device 100 in the workpiece clamping process, and thus improves the workpiece processing efficiency.
[0046] Example 2
[0047] refer to Figures 1 to 3 As shown, an embodiment of this application provides another clamping device 100 for clamping a workpiece for positioning processing. The clamping device 100 includes a base 110, a first clamping assembly 120, a second clamping assembly 130, and an adjusting member 140.
[0048] Specifically, in combination Figure 2 and Figure 3 As shown, the base 110 is provided with a guide rail 111. The first clamping assembly 120 includes a first clamping member 121 and a plurality of first movable positioning members 122. The first clamping member 121 is fixedly installed at one end of the base 110, and each of the first movable positioning members 122 is movably connected to one side of the first clamping member 121. The second clamping assembly 130 includes a second clamping member 131 and a plurality of second movable positioning members 132. The second clamping member 131 is slidably connected to the base 110 through the guide rail 111, and each of the second movable positioning members 132 is movably connected to one side of the second clamping member 131. The first movable positioning members 122 and the second movable positioning members 132 are arranged opposite to each other, and the workpiece is clamped by the first movable positioning members 122 and the second movable positioning members 132 to facilitate the worker's processing of the workpiece. The adjusting member 140 is movably connected to the second clamping member 131 so that the adjusting member 140 drives the second clamping assembly 130 to move relative to each other. Correspondingly, the base 110 of the clamping device 100 is provided with a guide rail 111. The adjusting member 140 drives the second clamping member 131 to move relative to the first clamping member 121 on the guide rail 111, so that the workpiece is placed between the first clamping assembly 120 and the second clamping assembly 130. The first movable positioning member 122 and the second movable positioning member 132 can move relative to each other to achieve the purpose of contacting and clamping the workpiece, so as to match the shape and size of the workpiece, reduce the situation of the workpiece loosening or sliding, and have a better clamping effect for workpieces such as irregularly shaped workpieces, thereby improving the reliability and stability of the clamping device 100 in the workpiece clamping process.
[0049] It should be noted that the reference Figures 1 to 4 As shown, the clamping device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the clamping device 100, the second direction Y refers to the width direction of the clamping device 100, and the third direction Z refers to the height direction of the clamping device 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the clamping device 100 and should not be construed as limitations on this application.
[0050] In one embodiment, alternatively, referencing Figure 1As shown, the adjusting member 140 drives the second clamping member 131 to move relative to each other along the first direction X on the guide rail 111. That is, the adjusting member 140 drives the second clamping member 131 to move relative to each other along the length direction of the clamping device 100 on the guide rail 111, so as to adjust the relative distance between the second clamping member 131 and the first clamping member 121, thereby causing the first movable positioning member 122 on the first clamping member 121 and the second movable positioning member 132 on the second clamping member 131 to contact and abut against the workpiece respectively. The adjusting member 140 can adjust and lock the position of the second clamping member 131. Exemplarily, the adjusting member 140 is an adjusting screw, which is threadedly connected to the second clamping member 131 to facilitate the relative movement of the second clamping member 131 on the guide rail 111.
[0051] Optionally, combined Figure 2 and Figure 3 As shown, multiple first movable positioning elements 122 are arranged parallel to each other along the first direction X, and multiple second movable positioning elements 132 are arranged parallel to each other along the first direction X. Correspondingly, multiple first movable positioning elements 122 are arranged parallel to each other along the length direction of the clamping device 100, and multiple second movable positioning elements 132 are arranged parallel to each other along the length direction of the clamping device 100. The first movable positioning elements 122 and the second movable positioning elements 132 are arranged opposite to each other, and the first movable positioning elements 122 and the second movable positioning elements 132 respectively clamp and position the opposite sides of the workpiece.
[0052] Optionally, refer to Figure 1 and Figure 2 As shown, multiple first movable positioning elements 122 are arranged in an array structure, and multiple second movable positioning elements 132 are arranged in an array structure. Each first movable positioning element 122 corresponds to one second movable positioning element 132. In other words, multiple first movable positioning elements 122 are arranged in an m*n array structure, and multiple second movable positioning elements 132 are arranged in an m*n array structure, where m≥2 and n≥2. The first movable positioning elements 122 and the second movable positioning elements 132 correspond one-to-one, which increases the clamping contact points on the workpiece, improves the clamping force on the workpiece, and prevents the workpiece from loosening and falling off, thus achieving better technical results.
[0053] In one embodiment, alternatively, referencing Figure 3 and Figure 4 As shown, both the first clamping member 121 and the second clamping member 131 are provided with multiple mounting slots 123. Each first movable positioning member 122 corresponds to one mounting slot 123, and each second movable positioning member 132 corresponds to one mounting slot 123. The first movable positioning member 122 is installed in the mounting slot 123, and the second movable positioning member 132 is installed in the mounting slot 123, so that both the first movable positioning member 122 and the second movable positioning member 132 can move relative to each other.
[0054] Optionally, combined Figure 4 and Figure 5 As shown, both the first movable positioning member 122 and the second movable positioning member 132 include an elastic member 124 and a fixing rod 125. The elastic member 124 is disposed in the mounting groove 123, and the fixing rod 125 is inserted into the mounting groove 123. One end of the fixing rod 125 is connected to the elastic member 124, and the end of the fixing rod 125 away from the elastic member 124 extends out of the groove of the mounting groove 123. In other words, when the workpiece is contacted and clamped by the first movable positioning member 122 and the second movable positioning member 132, the relative position of the fixing rod 125 changes due to the elastic member 124. By having multiple first movable positioning members 122 and multiple second movable positioning members 132 together cover the workpiece, the first clamping member 121 and the second clamping member 131 can maintain relative positioning during the workpiece clamping process. Exemplarily, the elastic member 124 is a constant pressure spring, and the fixing rod 125 moves relative to the workpiece through the constant pressure spring, causing the fixing rod 125 to abut against the workpiece and perform positioning and clamping of the workpiece.
[0055] Optionally, such as Figure 3 and Figure 4 As shown, the clamping device 100 also includes a hydraulic component. Both the first clamping member 121 and the second clamping member 131 define a hydraulic chamber 1231. The hydraulic component is connected to the hydraulic chamber 1231, which in turn connects to the mounting groove 123. The hydraulic component uses the hydraulic chamber 1231 to hydraulically clamp the fixing rod 125 within the mounting groove 123. It can be understood that the hydraulic component enables the fixing rod 125 to clamp and fix the workpiece, maintaining sufficient clamping force. The hydraulic component includes a controller for controlling the flow rate of hydraulic oil. The pressure of a liquid (e.g., hydraulic oil) pushes the fixing rod 125, and the hydraulic oil is delivered to the mounting groove 123 through the hydraulic chamber 1231. This provides precise control and rapid response, reducing assembly clamping time and improving clamping effectiveness, thereby achieving the clamping or releasing of the workpiece. For example, the hydraulic chamber 1231 is a sealed structure to prevent hydraulic oil leakage.
[0056] Optionally, refer to Figure 5 As shown, a liquid separator 1232 is provided in the hydraulic chamber 1231. The liquid separator 1232 has a through hole 1232a. The fixing rod 125 passes through the through hole 1232a. The liquid separator 1232 is used to separate the hydraulic oil in the hydraulic chamber 1231. The fixing rod 125 passes through the through hole 1232a of the liquid separator 1232.
[0057] Furthermore, such as Figure 5As shown, the liquid separator 1232 divides the hydraulic chamber 1231 into a first hydraulic chamber and a second hydraulic chamber. The first hydraulic chamber and the second hydraulic chamber are respectively provided with liquid flow holes 1231a. The first hydraulic chamber and the second hydraulic chamber are respectively provided with hydraulic oil. The hydraulic oil flows into or out of the first hydraulic chamber through the liquid flow holes 1231a, or the hydraulic oil flows into or out of the second hydraulic chamber through the liquid flow holes 1231a. The hydraulic component controls the hydraulic oil in the first hydraulic chamber or the second hydraulic chamber to push the fixing rod 125 to maintain the clamping force of the fixing rod 125, maintain the positioning and locking of the fixing rod 125, and further reduce the possibility of the fixing rod 125 becoming loose.
[0058] Optionally, combined Figure 4 and Figure 5 As shown, a sealing element 1233 is also provided in the mounting groove 123. The sealing element 1233 is sleeved on the fixing rod 125 and abuts against the fixing rod 125 and the hole wall of the through hole 1232a. The diameter of the through hole 1232a gradually increases from the groove opening of the mounting groove 123 to the elastic element 124. Under the flow regulation of the hydraulic oil in the first hydraulic chamber and the second hydraulic chamber, the sealing element 1233 can be clamped against the hole wall of the through hole 1232a or the sealing element 1233 can be disengaged from the hole wall of the through hole 1232a. This allows the fixing rod 125 to clamp the workpiece or the fixing rod 125 to move and cause the workpiece to fall off, thereby realizing the clamping and adjustment function of the clamping device 100. For example, the seal 1233 is a wedge-shaped structure, and the wedge-shaped seal 1233 corresponds to the shape and size of the through hole 1232a, which makes it easy for the seal 1233 to be released from the through hole 1232a.
[0059] The working principle of the clamping device 100: Hydraulic oil is introduced into the clamping device 100 through the hydraulic chamber 1231, increasing the pressure inside the hydraulic chamber 1231. The pressure inside the first hydraulic chamber is greater than the pressure inside the second hydraulic chamber, causing the wedge-shaped sealing member 1233 to engage with the wall of the through hole 1232a. Multiple first movable positioning members 122 and multiple second movable positioning members 132 each have the structure of the aforementioned hydraulic chamber 1231. The first hydraulic chambers of the multiple first movable positioning members 122 are interconnected, and the second hydraulic chambers of the multiple first movable positioning members 122 are interconnected. The hydraulic chambers 1231 of the second movable positioning members 132 have a similar structure. Without going into further detail, the hydraulic structure of the hydraulic chamber 1231 can increase the clamping force of the first movable positioning member 122 or the second movable positioning member 132, thereby allowing for individual control of the clamping force of the first movable positioning member 122 or the second movable positioning member 132, achieving precise control of the clamping force. Multiple first movable positioning members 122 and multiple second movable positioning members 132 together cover the workpiece to match the shape and size of the workpiece, achieving clamping and fixing of the workpiece and preventing it from falling off during operation. When the workpiece is released, hydraulic oil flows out through the fluid flow hole 1231a of the hydraulic chamber 1231 to achieve the purpose of pressure relief, so as to facilitate the removal of the workpiece.
[0060] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0061] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
