[0007] A first clamping mechanism for clamping a workpiece includes a support plate and a first clamping assembly. The support plate is used to support the workpiece, and the first clamping assembly is used to clamp the workpiece. The bottom of the support plate has a first positioning hole and a second positioning hole.

[0008] The second clamping mechanism is set on the processing machine table of the first processing step and is used to clamp the first clamping mechanism. It has a first positioning pin and a second positioning pin, and the first positioning pin and the second positioning pin are respectively positioned in conjunction with the first positioning hole and the second positioning hole.

[0046] The following is in conjunction with the appendix Figure 1-5 This invention describes a machining fixture for a robot vacuum cleaner mounting base according to an embodiment of the present invention.

[0047] This utility model aims to provide an embodiment of a machining fixture for a robot vacuum cleaner mounting base.

[0048] In this embodiment, a processing fixture for a robot vacuum cleaner mounting base mainly includes a first clamping mechanism 100, a second clamping mechanism 150, and a third clamping mechanism 180.

[0049] Reference Figure 1 The first clamping mechanism 100 is used to clamp the workpiece. The first clamping mechanism 100 includes a support plate 110 and a first clamping assembly 120. The support plate 110 is used to support the workpiece, and the first clamping assembly 120 is used to clamp the workpiece. The bottom of the support plate 110 has a first positioning hole 130 and a second positioning hole 140, thereby facilitating the fixing of the workpiece on the first clamping mechanism 100.

[0050] In some specific embodiments, the support plate 110 is provided with four support parts 210, which are used to abut against the bottom surface of the workpiece. Each of the four support parts 210 is provided with a first clamping component 120. The support parts 210 and the first clamping components 120 cooperate to clamp and fix the workpiece from above and below, thereby making the clamping of the workpiece by the support parts 210 and the first clamping components 120 more stable.

[0051] Furthermore, the top of the support 210 has a limiting step, which cooperates with the bottom protrusion of the workpiece for positioning, thereby facilitating the positioning of the workpiece by the first clamping mechanism 100.

[0052] In some specific embodiments, the first clamping assembly 120 includes a first clamping arm 220 and a first screw 230. The first clamping arm 220 is used to clamp the workpiece, and the first screw 230 is used to fix the first clamping arm 220 on the support plate 110, thereby facilitating the assembly and disassembly of the first clamping assembly 120.

[0053] In some specific embodiments, a positioning groove 240 is provided on the support plate 110. The positioning groove 240 is used to position the first pressure arm 220, thereby facilitating the installation and positioning of the first pressure arm 220 on the support plate 110.

[0054] In some specific embodiments, the first pressure arm 220 includes a column portion 250 and a horizontal arm portion 260 connected to the top of the column portion 250. The bottom end of the column portion 250 is positioned in conjunction with the positioning groove 240. The column portion 250 has a first mounting hole 270 for mounting the first screw 230. The horizontal arm portion 260 is used to press the workpiece, thereby allowing the horizontal arm portion 260 to extend toward the workpiece and allowing the column portion 250 to avoid the workpiece. In this way, the installation of the first pressing assembly 120 on the support plate 110 is prevented from interfering with the workpiece.

[0055] In some specific embodiments, the support plate 110 has a first clearance groove 290 that runs vertically through the workpiece. The first clearance groove 290 is used to avoid the bottom surface of the workpiece, thereby preventing the support plate 110 from interfering with the processing equipment's processing of the bottom surface of the workpiece.

[0056] Reference Figure 2 In some specific embodiments, the tool also includes a workpiece auxiliary assembly / disassembly tool 300. The workpiece auxiliary assembly / disassembly tool 300 includes a base plate 310, a fifth positioning pin 320, a sixth positioning pin 330 and a spring-loaded positioning post 340 disposed on the base plate 310. The base plate 310 is used to support the support plate 110. The fifth positioning pin 320 and the sixth positioning pin 330 are respectively positioned in conjunction with the first positioning hole 130 and the second positioning hole 140. The spring-loaded positioning post 340 passes through the first clearance groove 290 to support the workpiece. The top of the spring-loaded positioning post 340 has a third positioning hole 350, which is positioned in conjunction with the positioning boss of the workpiece. This facilitates the support and positioning of the first clamping mechanism 100 and the alignment and positioning of the workpiece when clamping the workpiece, thereby making it easier for the first clamping mechanism 100 to clamp the workpiece.

[0057] Reference Figure 3 Furthermore, the spring-loaded positioning pin 340 includes a sleeve 360, a set screw 370, a pin 380, and a spring 390. The sleeve 360 ​​is mounted on the base plate 310. The set screw 370 is threadedly connected to the bottom end of the sleeve 360. The spring 390 is disposed inside the sleeve 360. The pin 380 is disposed inside the sleeve 360 ​​and located above the spring 390. The two ends of the spring 390 abut against the top end of the set screw 370 and the bottom end of the pin 380, respectively. The third positioning hole 350 is disposed at the top end of the pin 380. Thus, by adjusting the height of the set screw 370, the height of the pin 380 can be adjusted, thereby facilitating the adjustment of the support height of the spring-loaded positioning pin 340 on the workpiece.

[0058] Furthermore, there are two spring-loaded positioning pins 340, which respectively cooperate with the two positioning bosses of the workpiece for positioning.

[0059] In some specific embodiments, the base plate 310 is also provided with a plurality of limiting posts 280, which pass through the first clearance groove 290 and abut against the outer side of the workpiece for limiting, thereby facilitating the positioning of the workpiece when clamping it.

[0060] Reference Figure 4 The second clamping mechanism 150 is set on the processing machine table of the first processing step. The second clamping mechanism 150 is used to clamp the first clamping mechanism 100. The second clamping mechanism 150 has a first positioning pin 160 and a second positioning pin 170. The first positioning pin 160 and the second positioning pin 170 are respectively positioned in conjunction with the first positioning hole 130 and the second positioning hole 140.

[0061] In some specific embodiments, the second clamping mechanism 150 includes a horizontal plate, a first cylinder and a second pressure arm. A first positioning pin 160 and a second positioning pin 170 are disposed on the horizontal plate. The horizontal plate is used to support the support plate 110. The first cylinder is used to drive the second pressure arm to press and release the support plate 110, thereby realizing the clamping of the first clamping mechanism 100 by the second clamping mechanism 150.

[0062] Furthermore, the second clamping mechanism 150 also includes a first base, a rotating frame, and a first motor that drives the rotating frame to rotate. The first motor is mounted on the first base, and the horizontal plate is connected to the rotating frame. The rotating frame rotates to drive the horizontal plate to flip, thereby facilitating the adjustment of the angle of the first clamping mechanism 100, and thus enabling the processing machine to process the surfaces of the workpiece in different directions.

[0063] In some specific embodiments, the horizontal plate has a second clearance groove that runs vertically through the workpiece. The second clearance groove is used to avoid the bottom of the workpiece, thereby preventing the horizontal plate from interfering with the processing of the bottom surface of the workpiece.

[0064] Reference Figure 5 The third clamping mechanism 180 is set on the processing machine table of the second processing step. The third clamping mechanism 180 is used to clamp the first clamping mechanism 100. The third clamping mechanism 180 has a third positioning pin 190 and a fourth positioning pin 200. The third positioning pin 190 and the fourth positioning pin 200 are respectively positioned in conjunction with the first positioning hole 130 and the second positioning hole 140.

[0065] In some specific embodiments, the third clamping mechanism 180 includes a vertical plate, a second cylinder and a third pressure arm, a third positioning pin 190 and a fourth positioning pin 200 are disposed on the vertical plate, the first clamping mechanism 100 is installed on the side of the vertical plate, and the second cylinder is used to drive the third pressure arm to press and release the support plate 110, thereby realizing the clamping of the first clamping mechanism 100 by the third clamping mechanism 180.

[0066] Furthermore, the third clamping mechanism 180 also includes a second base, a rotating plate, and a second motor. The second motor is mounted on the second base and is used to drive the rotating plate to rotate. The vertical plate is connected to the rotating plate. The rotation of the rotating plate drives the vertical plate to rotate in a direction perpendicular to the plane of the vertical plate, thereby facilitating the adjustment of the angle of the first clamping mechanism 100, and enabling the processing machine to process the surfaces of the workpiece in different directions.

[0067] In some specific embodiments, the first clamping mechanism 100 is respectively clamped to the second clamping mechanism 150 and the third clamping mechanism 180 to fix the workpiece on the processing machine table of the first processing step and the second processing step, respectively.

[0068] It is understandable that the second clamping mechanism 150 and the third clamping mechanism 180 can directly clamp and position the first clamping mechanism 100. By clamping the first clamping mechanism 100 into the second clamping mechanism 150 and the third clamping mechanism 180 respectively, the workpiece is fixed on the processing table of the first processing step and the second processing step respectively. Thus, during the switching process between the first processing step and the second processing step, the first clamping mechanism 100 can be exempted from disassembling and assembling the workpiece. In this way, the number of clamping steps of the workpiece can be reduced during the multi-process processing, the risk of crushing and bumping the workpiece can be reduced, and the clamping time can be reduced.

[0069] In some specific embodiments, the diameters of the first positioning hole 130 and the second positioning hole 140 are set to be different, and the first positioning pin 160, the second positioning pin 170, the third positioning pin 190, and the fourth positioning pin 200 are set to correspond. This allows the first positioning hole 130 and the second positioning hole 140 to correspond one-to-one with the first positioning pin 160 and the second positioning pin 170, the third positioning pin 190, and the fourth positioning pin 200, thus avoiding incorrect installation of the first clamping mechanism 100 on the second clamping mechanism 150 and the third clamping mechanism 180. This, in turn, facilitates the error-proof installation of the first clamping mechanism 100 on the second clamping mechanism 150 and the third clamping mechanism 180.
