In order to measure the amount of workpiece surface removal to meet the machining requirements, it is usually necessary to measure the removal amount by metering before and after sanding. In the current detection process, a workpiece usually requires multiple metering mechanisms, each of which is used to detect one of the surfaces of the workpiece. Due to the large number of metering mechanisms used, the detection efficiency is low and the detection cost is high. Utility Model Content

[0065] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0066] See also Figure 1 , an embodiment of the present application provides a metering device 100. The metering device 100 is used to measure the removal amount of a workpiece (not shown) before and after sanding. The metering device 100 includes a base 10, a clamping mechanism 20 and a detection mechanism 30. The clamping mechanism 20 is disposed on the base 10, and is used to clamp the workpiece so that the workpiece is fixed on the base 10. The detection mechanism 30 is spaced apart from the clamping mechanism 20. Before the workpiece is sanded, the detection mechanism 30 abuts against the side of the workpiece for a first measurement. After the workpiece is sanded, the detection mechanism 30 abuts against the same side of the workpiece for a second measurement. The difference between the two measurements is then compared to obtain the removal amount of the workpiece.

[0067] For ease of understanding, Figure 1 A three-dimensional coordinate system is established in the figure. The directions of the X-axis, the Y-axis and the Z-axis are as shown in the figure. The X-axis, the Y-axis and the Z-axis are perpendicular to each other, wherein the X-axis direction is defined as the first direction and the Y-axis direction is defined as the second direction.

[0068] See also Figures 1 to 3The base 10 includes a bottom plate 11, a support plate 12 and a plurality of pillars 13. Both the bottom plate 11 and the support plate 12 are rectangular plate structures, and the number of pillars 13 is four. The four pillars 13 are arranged between the bottom plate 11 and the support plate 12 to connect the bottom plate 11 and the support plate 12. A positioning member 121 for positioning the workpiece is provided on the side of the support plate 12 away from the bottom plate 11. The positioning member 121 is arranged adjacent to the clamping mechanism 20. When the workpiece is placed on the support plate 12, the positioning member 121 positions the workpiece to prevent the workpiece from shifting at will, so that the clamping mechanism 20 can accurately clamp the workpiece. In this embodiment, the positioning member 121 includes a plurality of positioning pins 122 arranged at intervals on the base 10 and a plurality of magnets 123 arranged at intervals on the base 10. Specifically, the plurality of positioning pins 122 are arranged on the side of the support plate 12 away from the bottom plate 11, and the plurality of magnets 123 are also arranged on the side of the support plate 12 away from the bottom plate 11, and the plurality of positioning pins 122 are arranged around the plurality of magnets 123. A plurality of positioning pins 122 are used to pre-position the workpiece. When the workpiece is placed on the support plate 12, a large deviation in the placement position of the workpiece is avoided. At the same time, a plurality of magnets 123 adsorb the workpiece to prevent the workpiece from shifting at will. A plurality of groups of protrusions 124 are provided at the edge of the support plate 12. The number of groups of protrusions 124 can be determined according to the actual processing conditions. Each group of protrusions 124 includes two protrusions 124 arranged opposite to each other. A cover plate 125 is provided on each group of protrusions 124. A plurality of first mounting grooves 126 are provided on the support plate 12. The plurality of first mounting grooves 126 are respectively located between the two protrusions 124 of each group. The plurality of groups of protrusions 124 are slidably connected to the clamping mechanism 20 and part of the structure of the clamping mechanism 20 is provided in the plurality of first mounting grooves 126. The plurality of groups of protrusions 124 guide the clamping mechanism 20. A plurality of receiving grooves 127 are formed on one side of the support plate 12 facing the bottom plate 11 . Part of the structure of the detection mechanism 30 is disposed in the plurality of receiving grooves 127 . In the present embodiment, the number of the receiving grooves 127 is four.

[0069] See also Figure 1 The clamping mechanism 20 includes two clamping assemblies 21 arranged at intervals, one of which is arranged along the X-axis direction, and the other is arranged along the Y-axis direction. The two clamping assemblies 21 clamp the workpiece from the X-axis and Y-axis directions respectively. In this way, by using the two clamping assemblies 21 to clamp the workpiece from different directions, the workpiece can be fixed more firmly.

[0070] See also Figure 1 , Figure 2 and Figure 4In this embodiment, the clamping assembly 21 includes a reference block 211 disposed on the base 10 and a clamping module 212 disposed on the base 10. Specifically, the reference block 211 is disposed on the side of the support plate 12 away from the bottom plate 11, wherein the reference block 211 and the clamping module 212 in one clamping assembly 21 are disposed on opposite sides of the positioning member 121 along the X-axis direction, and the reference block 211 and the clamping module 212 in another clamping assembly 21 are disposed on opposite sides of the positioning member 121 along the Y-axis direction. There may be multiple reference blocks 211 and clamping modules 212, and the number of clamping modules 212 matches the number of groups of protrusions 124, and each group of protrusions 124 guides the corresponding clamping modules 212. The specific number of reference blocks 211 and clamping modules 212 used may be determined according to the size of the workpiece.

[0071] The clamping module 212 includes a mobile driving member 213 disposed on the support plate 12, a push member 214 movably connected to the mobile driving member 213, and a reset member 215 disposed between the push member 214 and the support plate 12. The mobile driving member 213 is arranged opposite to the reference block 211, and the mobile driving member 213 includes a linear cylinder 2131 and a connecting block 2132 connected to the linear cylinder 2131, and a slide groove 2133 connected to the push member 214 is provided on the connecting block 2132. In this embodiment, the linear cylinder 2131 is connected to a manual valve (not shown), and the operator can control the movement of the linear cylinder 2131 through the manual valve. The linear cylinder 2131 is also connected to a speed regulating valve (not shown), and the operator can control the running speed of the linear cylinder 2131 through the speed regulating valve.

[0072] For example, the push member 214 can be I-shaped, one end of the push member 214 is slidably connected to the slide groove 2133 of the connecting block 2132, and can slide relative to the connecting block 2132 in the slide groove 2133, the other end of the push member 214 pushes the workpiece, the rod portion of the push member 214 is slidably connected between the two protrusions 124, the cover plate 125 is covered above the two protrusions 124, and the cover plate 125 limits the push member 214 between the two protrusions 124 to prevent the push member 214 from detaching from the two protrusions 124.

[0073] See also Figure 2 , Figure 4 and Figure 5 The push member 214 has a second mounting groove 2141 on one side facing the support plate 12, the second mounting groove 2141 is connected to the first mounting groove 126, the reset member 215 can be a spring, the reset member 215 is arranged in the first mounting groove 126 and protrudes into the second mounting groove 2141, and the two ends of the reset member 215 abut against the two opposite groove walls of the first mounting groove 126 and the two opposite groove walls of the second mounting groove 2141. By arranging the reset member 215 in the first mounting groove 126 and the second mounting groove 2141, the installation space can be saved.

[0074] During the implementation of the clamping module 212, the piston rod of the linear cylinder 2131 contracts and drives the push member 214 away from the reference block 211 through the connecting block 2132. At this time, the push member 214 compresses the reset member 215. The workpiece is placed on the support plate 12, and the piston rod of the linear cylinder 2131 extends and resets. At this time, the reset member 215 resets and pushes the push member 214 toward the workpiece to press the workpiece against the reference block 211. When the workpiece is pressed by the push member 214 in the X-axis direction and the Y-axis direction, the workpiece completes the clamping action. In this way, since the push member 214 is driven by the reset member 215 to clamp, the push member 214 elastically abuts the workpiece under the elastic force of the reset member 215, thereby protecting the workpiece to prevent the workpiece from being clamped.

[0075] In this embodiment, the number of the reference block 211 and the clamping module 212 in the clamping assembly 21 arranged along the X-axis direction are both two, and the two reference blocks 211 and the two clamping modules 212 correspond one to one; the number of the reference block 211 and the clamping module 212 in the other clamping assembly 21 arranged along the Y-axis direction are both one, but the clamping module 212 includes two movable driving members 213 and one pushing member 214, and the two movable driving members 213 jointly drive the same pushing member 214 to press the workpiece.

[0076] See also Figure 1 , Figure 3 and Figure 6 The detection mechanism 30 includes a plurality of sliding members 31 arranged at intervals, a driving assembly 32 arranged on the base 10, and a plurality of detection assemblies 33. The plurality of sliding members 31 are slidably connected to the side of the support plate 12 of the base 10 facing the bottom plate 11, and the extension direction of the plurality of sliding members 31 is perpendicular to the workpiece. In this embodiment, the number of sliding members 31 is four, and the sliding members 31 include a sliding rod 311 and a lever 312, wherein two sliding rods 311 extend along the X-axis direction, and the other two sliding rods 311 extend along the Y-axis direction. The four sliding rods 311 are in a cross shape, and the ends of the four sliding rods 311 close to each other are provided with a driven inclined surface 313, and the end of each sliding rod 311 away from the driven inclined surface 313 is connected to the lever 312, and the lever 312 is perpendicular to the sliding rod 311, and the end of the lever 312 away from the sliding rod 311 passes through the support plate 12 and is connected to the detection assembly 33.

[0077] The driving assembly 32 is arranged in the middle of the four sliding members 31, and the driving assembly 32 includes a lifting driving member 321 connected to the base 10, a driving block 322 connected to the lifting driving member 321, and a plurality of elastic members 323. Specifically, the lifting driving member 321 can be a cylinder, the lifting driving member 321 is connected to the bottom plate 11, and is located between the bottom plate 11 and the support plate 12, and the lifting driving member 321 drives the driving block 322 to move along the Z-axis direction to approach or move away from the support plate 12 of the base 10. In this embodiment, the lifting driving member 321 is connected to a manual valve, and the operator can control the lifting movement of the lifting driving member 321 through the manual valve. The lifting driving member 321 is also connected to a speed regulating valve, and the operator can control the lifting speed of the lifting driving member 321 through the speed regulating valve.

[0078] A plurality of sliding members 31 are arranged around the driving block 322, and one end of the plurality of sliding members 31 close to the driving block 322 is matched with the inclined surface of the driving block 322. Specifically, the driving block 322 is provided with a plurality of driving inclined surfaces 324, and the number of the driving inclined surfaces 324 is four. The four driving inclined surfaces 324 are arranged around the driving block 322, and one end of the four driving inclined surfaces 324 away from the lifting driving member 321 is close to each other, and one end of the four driving inclined surfaces 324 close to the lifting driving member 321 is open, and the driven inclined surfaces 313 of the four sliding members 31 correspond to and abut against the four driving inclined surfaces 324 one by one.

[0079] The elastic member 323 may be a spring, and the number of the elastic members 323 is four. The plurality of elastic members 323 corresponds to the plurality of sliding members 31 one by one. The two ends of the elastic member 323 abut against the support plate 12 of the base 10 and the corresponding sliding member 31, respectively. The sliding member 31 always abuts against the driving inclined surface 324 of the driving block 322 under the elastic force of the corresponding elastic member 323. Specifically, a receiving groove 314 is provided on the slide bar 311 of each sliding member 31. The receiving grooves 314 on the four slide bars 311 correspond to and communicate with the four receiving grooves 127 one by one. The elastic member 323 is arranged in the receiving groove 314 and the elastic member 323 protrudes into the receiving groove 127. The two ends of the elastic member 323 abut against the two opposite groove walls of the receiving groove 314 and the two opposite groove walls of the receiving groove 127, respectively. By arranging the elastic member 323 in the receiving groove 314 and the receiving groove 127, the installation space can be saved, and the structure can be made more compact.

[0080] During the implementation of the driving assembly 32, the lifting driving member 321 drives the driving block 322 to move close to the support plate 12. At this time, the multiple driving inclined surfaces 324 on the driving block 322 push the corresponding driven inclined surfaces 313, so that the multiple sliding bars 311 slide in the direction away from the driving block 322. At this time, the multiple sliding bars 311 compress the corresponding elastic members 323, and the multiple sliding bars 311 drive the corresponding detection assemblies 33 to move through the lever 312 so that the multiple detection assemblies 33 avoid the workpiece. Then the workpiece is placed on the support plate 12 for positioning and clamping, and then the lifting driving member 321 drives the driving block 322 to move away from the support plate 12, and the multiple elastic members 323 drive the corresponding sliding bars 311 to slide, so that the multiple sliding bars 311 drive the corresponding detection assemblies 33 to abut against the workpiece through the lever 312, so as to perform measurement.

[0081] See also Figure 1 and Figure 7 The detection assembly 33 includes a mounting seat 331 connected to the base 10, a header 332 slidably inserted into the mounting seat 331, and a detection member 333 connected to the mounting seat 331. Specifically, the mounting seat 331 is connected to the edge of the support plate 12, one end of the header 332 protrudes out of the mounting seat 331 for abutting against the workpiece, and the other end of the header 332 is located in the mounting seat 331. At the same time, the lever 312 passes through the mounting seat 331 and is sleeved on the header 332, and the lever 312 can slide along the header 332. In order to increase the service life of the header 332, the header 332 is made of ceramic material, so that the header 332 is more wear-resistant. The detection member 333 can be a micrometer, the detection member 333 is installed on the mounting seat 331, and the measuring rod 334 of the detection member 333 is connected to the other end of the header 332.

[0082] During the measurement process of the detection component 33, the lifting drive member 321 drives the multiple slide bars 311 to slide in the direction away from the drive block 322 through the drive block 322, and the multiple slide bars 311 drive the lever 312 to move together. At this time, the lever 312 pushes the corresponding header 332 to move to avoid the workpiece, and at the same time, the header 332 squeezes the measuring rod 334 of the corresponding detection member 333; the workpiece is placed on the support plate 12 and clamped, the lifting drive member 321 drives the drive block 322 to move away from the support plate 12, and the multiple elastic members 323 drive the corresponding slide bars 311 to reset. At this time, the slide bar 311 no longer pushes the header 332 through the lever 312, and the measuring rod 334 of the detection member 333 resets and drives the header 332 to abut against the workpiece, thereby performing measurement. It should be noted that a pin or step structure can be set on one end of the meter head 332 close to the detection member 333. When the lever 312 slides along the meter head 332 and abuts against the pin or step structure, the slide bar 311 drives the meter head 332 to move through the lever 312 to avoid the workpiece.

[0083] The working process of the metering device 100 provided in the embodiment of the present application is roughly as follows:

[0084] First, place the zeroing block on the support plate 12, and then place the gauge head 332 against the zeroing block to perform zeroing. After the zeroing operation of the detection member 333 is completed, the workpiece that has not been sanded is ready to be measured. First, the lifting drive member 321 drives the drive block 322 to move toward the support plate 12. The drive block 322 drives the multiple slide bars 311 to slide through the multiple drive inclined surfaces 324. The multiple slide bars 311 drive the corresponding gauge heads 332 to move through the lever 312 to avoid the workpiece. The workpiece is placed in a plurality of positioning pins 122, and a plurality of magnets 123 are used to adsorb and position the workpiece. Then, the reset members 215 in the two clamping assemblies 21 drive the corresponding push members 214 to press the workpiece, so that the workpiece abuts against a plurality of reference blocks 211 in the X-axis direction and the Y-axis direction. When the workpiece is clamped in the X-axis direction and the Y-axis direction, the lifting drive member 321 drives the drive block 322 to move away from the support plate 12, and the plurality of elastic members 323 drive the corresponding slide bar 311 to slide in the direction close to the drive block 322. At this time, the measuring rod 334 of the detection member 333 drives the meter head 332 to abut against the workpiece, so as to perform measurement. After the workpiece is sanded, the workpiece is placed on the support plate 12 to measure the same side, and the removal amount of the workpiece is obtained by comparing the two measured values.

[0085] By adopting the above-mentioned metering device 100, the metering device 100 can continuously measure the workpiece only by performing a zeroing operation once, which is conducive to improving the detection efficiency. Since during the detection process, multiple detection members 333 can measure multiple surfaces on the workpiece at the same time, the number of metering devices 100 used is reduced, and the detection cost is reduced. In addition, since the metering device 100 can measure multiple surfaces of the workpiece at one time, the detection efficiency of the workpiece is improved.

[0086] Since the workpiece is attracted and positioned by the magnet 123 before being clamped, the workpiece is not easily deviated at will, so that the push member 214 can accurately press the workpiece against the reference block 211 .

[0087] Because the push member 214 elastically contacts the workpiece under the action of the reset member 215 , the push member 214 is prevented from causing crushing damage to the workpiece, thereby protecting the workpiece.

[0088] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
