In the related art, in the process of processing workpieces, there are workpieces with special shapes, such as polygonal and unilateral shapes. Due to the irregular shape of the workpiece, it is difficult to position and clamp the workpiece during processing. There is a situation where the workpiece is loose or offset when clamping, which makes the workpiece processing inconvenient and affects the processing efficiency of the workpiece.

The first movable positioning member 122 and the second movable positioning member 132 are arranged opposite to each other. The workpiece is clamped by the first movable positioning member 122 and the second movable positioning member 132, so that the staff can process 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 member 130 to move relative to each other. Accordingly, 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 on the guide rail 111 relative to the first clamping member 121, so that the workpiece is placed between the first clamping member 120 and the second clamping member 130.

It has a better clamping effect on workpieces such as special-shaped workpieces, thereby improving the reliability and stability of the clamping process of the clamping device 100 for the workpiece.

[0039] It is understandable that if Figure 1 As shown, multiple first movable positioning members 122 and multiple second movable positioning members 132 work together to clamp and position the workpiece. After the first clamping member 121 and the second clamping member 131 maintain relative positioning, since the multiple first movable positioning members 122 and the multiple second movable positioning members 132 are relatively movable and have a larger adjustment range, the first movable positioning members 122 and the second movable positioning members 132 form a contoured structure corresponding to the shape of the workpiece, further avoiding the situation where the special shape or size of the workpiece causes insufficient clamping force and loosening, and contacting and clamping the workpiece according to the shape and size of the workpiece to adapt to workpieces of different shapes and sizes.

[0040] It should be noted that the reference Figures 1 to 4 As shown, the clamp 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. Exemplarily, the first direction X is taken as the length direction of the clamp device 100, the second direction Y is taken as the width direction of the clamp device 100, and the third direction Z is taken as the height direction of the clamp device 100.

[0041] In one embodiment, optionally, reference Figure 1 As shown, the adjusting member 140 drives the second clamping member 131 to move relative to 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 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, so as to make 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 the workpiece respectively, and the adjusting member 140 can adjust and position 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 in parallel along the first direction X, and a plurality of second movable positioning members 132 are arranged in parallel along the first direction X. Accordingly, a plurality of first movable positioning members 122 are arranged in parallel with each other along the length direction of the clamp device 100, and a plurality of second movable positioning members 132 are arranged in parallel with each other along the length direction of the clamp device 100, and 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 are respectively clamped and positioned on opposite sides of the workpiece.

[0044] Optionally, combined Figure 4 and Figure 5 As shown, the first movable positioning member 122 and the second movable positioning member 132 both include an elastic member 124 and a fixing rod 125, the elastic member 124 is arranged in the installation groove 123, the fixing rod 125 is inserted in the installation groove 123, and one end of the fixing rod 125 is connected to the elastic member 124, and one end of the fixing rod 125 away from the elastic member 124 extends out of the notch of the installation 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 is changed by the elastic member 124, and the workpiece is jointly covered by multiple first movable positioning members 122 and multiple second movable positioning members 132, so that the first clamping member 121 and the second clamping member 131 can maintain relative positioning during the process of clamping the workpiece.

[0045] In summary, the base 110 of the clamping device 100 is provided with a guide rail 111, and the adjusting member 140 drives the second clamping member 131 to move on the guide rail 111 relative to the first clamping member 121, so that the workpiece is placed between the first clamping component 120 and the second clamping component 130, and the workpiece is clamped by the first movable positioning member 122 and the second movable positioning member 132 to facilitate the staff to 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 and reduce the loosening or sliding of the workpiece. It has a better clamping effect on workpieces such as special-shaped workpieces, improves the reliability and stability of the clamping process of the clamping device 100 for the workpiece, and thus improves the workpiece processing efficiency.

[0046] Example 2

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, combined Figure 2 and Figure 3 As shown, the base 110 is provided with a guide rail 111.

Any of the second movable positioning members 132 is movably connected to one side of the second clamping member 131. The first movable positioning member 122 and the second movable positioning member 132 are arranged opposite to each other. The workpiece is clamped by the first movable positioning member 122 and the second movable positioning member 132, so that the staff can process 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 member 130 to move relative to each other. Accordingly, 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 on the guide rail 111 relative to the first clamping member 121, so that the workpiece is placed between the first clamping member 120 and the second clamping member 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 and reduce the loosening or sliding of the workpiece. It has a better clamping effect on workpieces such as special-shaped workpieces, thereby improving the reliability and stability of the clamping process of the clamping device 100 for the workpiece.

[0049] It should be noted that the reference Figures 1 to 4 As shown, the clamp 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 vertically in pairs. Exemplarily, the first direction X is taken as the length direction of the clamp device 100, the second direction Y is taken as the width direction of the clamp device 100, and the third direction Z is taken as the height direction of the clamp device 100. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of each part in the clamp device 100, and should not be understood as a limitation to the present application.

[0050] In one embodiment, optionally, reference Figure 1As shown, the adjusting member 140 drives the second clamping member 131 to move relatively on the guide rail 111 along the first direction X, that is, the adjusting member 140 drives the second clamping member 131 to move relatively on the guide rail 111 along the length direction of the clamping device 100 to adjust the relative distance between the second clamping member 131 and the first clamping member 121, so as to make 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 the workpiece respectively, and the adjusting member 140 can adjust and position 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 so as to drive the second clamping member 131 to move relatively on the guide rail 111.

[0051] Optionally, combined Figure 2 and Figure 3 As shown, a plurality of first movable positioning members 122 are arranged in parallel along the first direction X, and a plurality of second movable positioning members 132 are arranged in parallel along the first direction X. Accordingly, a plurality of first movable positioning members 122 are arranged in parallel with each other along the length direction of the clamp device 100, a plurality of second movable positioning members 132 are arranged in parallel with each other along the length direction of the clamp device 100, and 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 are respectively clamped and positioned on opposite sides of the workpiece.

[0052] Optionally, refer to Figure 1 and Figure 2 As shown, multiple first movable positioning members 122 are arranged in an array structure, and multiple second movable positioning members 132 are arranged in an array structure, and each first movable positioning member 122 corresponds to one second movable positioning member 132. In other words, multiple first movable positioning members 122 are arranged in an m*n array structure, and multiple second movable positioning members 132 are arranged in an m*n array structure, wherein m≥2, n≥2, and the first movable positioning members 122 and the second movable positioning members 132 correspond one to one, thereby increasing the clamping contact points on the workpiece, improving the clamping force on the workpiece, and preventing the workpiece from loosening and falling, thereby having a better technical effect.

[0053] In one embodiment, optionally, reference Figure 3 and Figure 4 As shown, the first clamping member 121 and the second clamping member 131 are both provided with a plurality of mounting grooves 123, each first movable positioning member 122 corresponds to a mounting groove 123, each second movable positioning member 132 corresponds to a mounting groove 123, the first movable positioning member 122 is installed in the mounting groove 123, and the second movable positioning member 132 is installed in the mounting groove 123, so that the first movable positioning member 122 and the second movable positioning member 132 can both move relative to each other.

[0054] Optionally, combined Figure 4 and Figure 5 As shown, the first movable positioning member 122 and the second movable positioning member 132 both include an elastic member 124 and a fixed rod 125, the elastic member 124 is disposed in the mounting groove 123, the fixed rod 125 is inserted in the mounting groove 123, and one end of the fixed rod 125 is connected to the elastic member 124, and one end of the fixed rod 125 away from the elastic member 124 extends out of the notch of the mounting groove 123. In other words, when the first movable positioning member 122 and the second movable positioning member 132 contact and clamp the workpiece, the relative position of the fixed rod 125 changes through the elastic member 124, and the workpiece is covered by a plurality of first movable positioning members 122 and a plurality of second movable positioning members 132, so that the first clamping member 121 and the second clamping member 131 can maintain relative positioning during the clamping process. Exemplarily, the elastic member 124 is a constant pressure spring, and the fixed rod 125 moves relative to the constant pressure spring, so that the fixed rod 125 abuts against the workpiece and positions and clamps the workpiece.

[0055] Alternatively, if Figure 3 and Figure 4 As shown, the clamp device 100 also includes a hydraulic component, and the first clamping component 121 and the second clamping component 131 both define a hydraulic chamber 1231, and the hydraulic component is connected to the hydraulic chamber 1231, and the hydraulic chamber 1231 is connected to the mounting groove 123. The hydraulic component hydraulically clamps the fixed rod 125 in the mounting groove 123 through the hydraulic chamber 1231. It can be understood that the use of the hydraulic component can enable the fixed rod 125 to clamp and fix the workpiece to maintain sufficient clamping force. The hydraulic component includes a controller, and the controller is used to control the flow of hydraulic oil. The fixed rod 125 is pushed by the pressure of a liquid (such as hydraulic oil), and the hydraulic oil is transported to the mounting groove 123 through the hydraulic chamber 1231, which has the characteristics of precise control and rapid response, reduces the assembly clamping time, and improves the clamping effect, thereby achieving the clamping or loosening of the workpiece. Exemplarily, the hydraulic chamber 1231 is a sealing structure to avoid oil leakage of the hydraulic oil.

[0056] Optionally, refer to Figure 5 As shown, a liquid barrier 1232 is provided in the hydraulic chamber 1231, and the liquid barrier 1232 is provided with a through hole 1232a. The fixing rod 125 is passed through the through hole 1232a. The liquid barrier 1232 is used to separate the hydraulic oil in the hydraulic chamber 1231, and the fixing rod 125 passes through the through hole 1232a of the liquid barrier 1232.

[0057] Furthermore, if Figure 5As shown, the liquid-isolating member 1232 separates 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 a liquid flow hole 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 hole 1231a, or the hydraulic oil flows into or out of the second hydraulic chamber through the liquid flow hole 1231a. The hydraulic member 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 loosening of the fixing rod 125.

[0058] Optionally, combined Figure 4 and Figure 5 As shown, a sealing member 1233 is further provided in the installation groove 123, and the sealing member 1233 is sleeved on the fixing rod 125, and the sealing member 1233 abuts between the fixing rod 125 and the hole wall of the through hole 1232a, and the aperture of the through hole 1232a gradually increases from the notch of the installation groove 123 to the direction of the elastic member 124, so that under the flow adjustment of the hydraulic oil in the first hydraulic chamber and the second hydraulic chamber, the sealing member 1233 can clamp the hole wall of the through hole 1232a or the sealing member 1233 can be detached from the hole wall of the through hole 1232a, thereby enabling the fixing rod 125 to clamp the workpiece or the fixing rod 125 to move to make the workpiece fall off, thereby realizing the clamping and adjusting effect of the clamping device 100. Exemplarily, the sealing member 1233 is a wedge-shaped structure, and the sealing member 1233 of the wedge-shaped structure corresponds to the shape and size of the through hole 1232a, so that the sealing member 1233 can be easily loosened from the through hole 1232a.

[0059] Working principle of the clamp device 100: The clamp device 100 introduces hydraulic oil through the hydraulic chamber 1231 to increase the pressure in the hydraulic chamber 1231. The pressure in the first hydraulic chamber is greater than the pressure in the second hydraulic chamber, so that the seal 1233 of the wedge-shaped structure is clamped on the hole wall position of the through hole 1232a. The plurality of first movable positioning members 122 and the plurality of second movable positioning members 132 respectively have the structure of the hydraulic chamber 1231. The first hydraulic chambers of the plurality of first movable positioning members 122 are connected, and the second hydraulic chambers of the plurality of first movable positioning members 122 are connected. The hydraulic chamber 1231 of the second movable positioning member 132 has a similar structure. It will not be elaborated here. The clamping force of the first movable positioning member 122 or the second movable positioning member 132 can be increased through the hydraulic structure of the hydraulic chamber 1231, and then the clamping force of the first movable positioning member 122 or the second movable positioning member 132 can be controlled individually to achieve fine control of the clamping force. Multiple first movable positioning members 122 and multiple second movable positioning members 132 jointly cover the workpiece to match the shape and size of the workpiece, thereby achieving clamping and fixing the workpiece to prevent the workpiece from falling off. When the workpiece is loosened, the hydraulic oil flows out through the liquid 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 limiting, and thus other examples of the exemplary embodiments may have different values.

[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
