Description

Technical Field

[0001] The present invention relates to the technical field of medical device assembly equipment, in particular to a target wire assembly device. Background Art

[0002] A target wire specimen is a common device for testing the imaging resolution of ultrasonic transducers. It consists of a supporting specimen and two sets of equally spaced target wires mounted on it. These wires can be made of metal with high acoustic impedance characteristics. During ultrasonic transducer resolution testing, multiple sets of target wire specimens of varying specifications are typically used. These target wires have varying spacing between them. During testing, the minimum resolution of the system is determined by sequentially imaging the target wire specimens with varying spacing.

[0003] In the prior art, target lines are fixed on a test piece, and target lines with different spacings are fixed on the test piece to form a test piece with multiple spacing specifications. Due to the needs of resolution testing, the spacing between two target lines needs to be set at the micron level.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The present invention provides a target wire assembly device for assembling two sets of parallel target wires 100 on a specimen 300 to form a target wire specimen 110 .

[0042] like Figures 1-6As shown, the first embodiment of the present invention provides a target line assembly device, comprising: a specimen fixing seat 200, a feeler gauge 400, a base plate 500, a target line fixing seat 600 and a target line adjustment seat 700; the specimen fixing seat 200, the target line fixing seat 600 and the target line adjustment seat 700 are all arranged on the base plate 500, the specimen fixing seat 200 is used to fix the specimen 300 and the feeler gauge 400; the target line fixing seat 600 and the target line adjustment seat 700 are respectively located on both sides of the specimen fixing seat 200, and the target line fixing seat 600 is used to fix One end of the two sets of target wires 100; the target wire adjustment seat 700 is used to fix the other ends of the two sets of target wires 100 and adjust the tension of the two sets of target wires 100; after the two sets of target wires 100 are led out from the target wire fixing seat 600, they pass through the two sides of the feeler gauge 400 and are respectively attached to the test piece 300. The other ends are fixed in the target wire adjustment seat 700 and then tightened, so that the two sets of target wires 100 are closely attached to the feeler gauge 400 from both sides and then fixed to the test piece 300. The target wires 100 are then cut from both ends of the test piece 300 to obtain a target wire test piece 110.

[0043] The present invention can adjust the distance of the target line 100 on the target line specimen 110 by setting feeler gauges 400 of different thicknesses on the specimen fixing seat 200, thereby accurately obtaining target line specimens 110 of different specifications.

[0044] It should be noted that the target wire assembly device provided in this embodiment is capable of assembling target wire specimens 110 with different spacing specifications. Specifically, the size of the feeler gauge 400 is selected according to the required specifications, the feeler gauge 400 is positioned and connected to the specimen fixing seat 200, and the specimen 300 is sequentially mounted on the specimen fixing seat 200. The target wire fixing seat 600 and the target wire adjustment seat 700 are tightly connected to the two sets of target wires 100. The target wire adjustment seat 700 is moved relative to the base plate 500 in a direction away from the target wire fixing seat 600. At this time, the two sets of target wires are brought into close contact with each other during the stretching and tensioning process. By aligning the two sets of target wires 100 by the width of the feeler gauge 400, that is, the two sets of target wires 100 can be aligned with the surfaces on both sides of the feeler gauge 400 respectively, and by assembling the two sets of target wires 100 with the specimen 300 at the predetermined spacing, positioning and assembly of the target wires 100 are achieved. In particular, the target wire 100 can be assembled for specimens 300 of different specifications based on the different thicknesses of the feeler gauge 400.

[0045] The target wire assembly device provided by the present invention can set a feeler gauge 400 with a diameter of 50 μm to 300 μm on a mounting seat of a test piece 300 .

[0046] In this embodiment, feeler gauges 400 of 50 μm, 100 μm, 150 μm, 200 μm, 250 μm, and 300 μm may be respectively set on the mounting seat of the specimen 300 to obtain target line specimens 110 of different specifications.

[0047] It should be noted that since the target wire specimen 110 includes two sets of parallel target wires 100, two sets of target wires 100 need to be assembled on the specimen 300. However, during the assembly of the target wires 100, the two target wires 100 can be directly fixed using the target wire fixing base 600, or a long target wire 100 can be bent to form two target wires 100 and assembled on the specimen 300.

[0048] Optionally, the target wire fixing seat 600 can adopt a fixed column structure, that is, the target wire fixing seat 600 is a fixed column set on the substrate 500, and two target wires 100 are formed by winding one target wire 100 around the fixed column structure, that is, both ends of one target wire 100 are connected to the target wire adjustment seat 700, and the fixed column structure is used to complete the bending of one target wire 100, and after the distance between the two target wires 100 between the target wire fixing seat 600 and the target wire adjustment seat 700 is determined by the feeler gauge 400, the two target wires 100 are assembled with the specimen 300 on the basis of the target wire adjustment seat 700 driving the target wire 100 to be tightened; in addition, the target wire fixing seat 600 can also adopt an arc column or a fixed needle, etc., and the specific structure of the target wire fixing seat 600 is not limited here.

[0049] On the basis of the above embodiment, further, in a preferred embodiment of the present invention, the test piece 300 has a U-shaped structure, and the test piece fixing seat 200 is provided with a receiving groove for accommodating the test piece 300 .

[0050] In this embodiment, the specimen 300 can adopt a U-shaped structure, with the target wire 100 mounted on the side wall near the opening of the specimen 300. When the specimen 300 is placed in the receiving groove, the side wall for mounting the target wire 100 faces upward, and the feeler gauge 400 is placed in the notch of the specimen 300 structure. After the two target wires 100 are attached to the side walls of the specimen 300 from both sides of the feeler gauge 400, they can be connected and fixed by bonding or clamping and wrapping, completing the assembly of the target wire 100 to the specimen 300. Preferably, the connection method between the specimen 300 and the target wire 100 is bonding.

[0051] In a preferred embodiment of the present invention, the specimen fixing seat 200 includes a fixing seat body 201, a clamping block 202 and a first knob 203; the accommodating groove is located on the fixing seat body 201, the clamping block 202 is connected to the fixing seat body 201, and the clamping block 202 is located inside the groove of the specimen 300, and the first knob 203 is transmission-connected to the fixing seat body 201, and the first knob 203 is directly opposite the opening of the specimen 300. By adjusting the first knob 203, feeler gauges 400 of different thicknesses can be fixed between the clamping block 202 and the first knob 203.

[0052] In this embodiment, the fixing base body 201 is mounted on the surface of the substrate 500, and a receiving groove is defined on a side of the fixing base body 201 facing away from the substrate 500. Since the test piece 300 has the groove, after the test piece 300 is clamped in the receiving groove, the clamping block 202 is located in the middle of the groove, and the first knob 203 is located at the opening of the test piece 300. That is, when the feeler gauge 400 is located between the buckle and the first knob 203, the feeler gauge 400 is clamped and fixed between the buckle and the first knob 203 during the process of moving the first knob 203 along the fixing base body 201. Since the feeler gauge 400 is located at the opening of the test piece 300, after the two target lines 100 are respectively attached to the two sides of the feeler gauge 400, the assembly and fixation can be completed by attaching the two target lines 100 to the surface of the test piece 300.

[0053] Optionally, the first knob 203 may be a threaded knob, and a clamping plate may be provided at the end of the first knob 203, that is, when the first knob 203 reciprocates with the fixing seat body 201 in a threaded rotation manner, the clamping plate moves in a direction close to the clamping block 202, and the clamping plate and the clamping block 202 are used to clamp and fix the two sides of the feeler gauge 400, thereby ensuring the clamping and fixation of feeler gauges 400 of different thicknesses.

[0054] In a preferred embodiment of the present invention, the specimen fixing seat 200 also includes a fixed slide rail 204, an adjustment module 205 and a limit member 206; the fixed slide rail 204 is fixedly connected to the substrate 500, and the extension direction of the fixed slide rail 204 is arranged perpendicular to the surface of the substrate 500; the fixing seat body 201 is slidably connected to the fixed slide rail 204, and the adjustment module 205 is respectively transmission-connected to the fixed slide rail 204 and the fixing seat body 201, and the adjustment module 205 is used to drive the fixing seat body 201 to move back and forth along the extension direction of the fixed slide rail 204, so that the fixing seat body 201 moves relatively away from or close to the substrate 500, so that the specimen 300 can form a surface fit with the two target lines 100; the limit member 206 is respectively connected to the fixing seat body 201 and the fixed slide rail 204, and the limit member 206 is used to connect the fixing seat body 201 to the fixed slide rail 204 in a relatively fixed position.

[0055] In this embodiment, the fixed slide rail 204 is fixedly connected to the substrate 500, and the fixed seat body 201 is slidably connected to the fixed slide rail 204 in a sliding manner. The adjustment module 205 can be connected to the fixed slide rail 204 and the fixed seat body 201 respectively. The adjustment of the adjustment module 205 drives the fixed seat body 201 to move back and forth along the direction defined by the fixed slide rail 204. Since the fixed slide rail 204 is arranged perpendicular to the surface of the substrate 500, the movement direction of the fixed seat body 201 is along the direction close to or away from the substrate 500. 00. Specifically, after the two target wires 100 are attached to both sides of the feeler gauge 400 under the action of the target wire fixing seat 600 and the target wire adjusting seat 700, in order to make the test piece 300 and the two target wires 100 form a bond, the fixing seat body 201 is driven by the adjusting module 205 to move in the direction close to the target wires 100. After the test piece 300 and the target wire 100 are bonded, the fixing seat body 201 is fixed by the limiting member 206, and then the target wire 100 and the test piece 300 are assembled by gluing.

[0056] Optionally, the adjustment module 205 may include a knob, a gear and a rack. After the fixed slide rail 204 and the fixed seat body 201 complete the sliding fit, the rack is connected to the fixed slide rail 204, and the extension direction of the rack is the same as the direction of the fixed slide rail 204. The gear can be located inside the fixed seat body 201, and the gear and the fixed seat body 201 are rotatably connected. The gear and the rack are meshed and connected. The knob passes through the side wall of the fixed seat body 201 and is connected to the gear. When the knob drives the gear to rotate, the gear can rotate along the extension direction of the rack. The fixed seat body 201 is moved relative to the fixed slide rail 204 by the rotation of the gear and rack. The movement direction of the fixed seat body 201 is controlled by controlling the direction of the knob.

[0057] Optionally, the limiting member 206 can be a limiting column, a first limiting hole is provided on the fixed seat body 201, and a second limiting hole is provided through the fixed slide rail 204. There can be multiple second limiting holes, and multiple second limiting blocks are arranged at intervals along the direction of the fixed slide rail 204. When the fixed seat body 201 moves back and forth along the fixed slide rail 204, the first limiting hole can be arranged corresponding to any second limiting hole. When the adjustment module 205 drives the fixed seat body 201 to move to the corresponding position, the limiting columns are inserted into the first limiting hole and the corresponding second limiting hole in sequence, and the fixation of the fixed seat body 201 is ensured by the interference of the limiting columns.

[0058] In a preferred embodiment of the present invention, the target line adjustment seat 700 includes a target line clamping plate 701, a linear motion mechanism 702 and an adjustment base 703; the adjustment base 703 is fixedly connected to the base plate 500, and the adjustment base 703 and the target line clamping plate 701 are assembled and slidably connected. A clamping groove is provided at one end of the target line clamping plate 701 away from the adjustment base 703, and the target line clamping plate 701 clamps and fixes the two target lines 100 through the clamping groove; the linear motion mechanism 702 is respectively connected to the target line clamping plate 701 and the adjustment base 703, and the linear motion mechanism 702 is used to drive the target line clamping plate 701 to move back and forth relative to the adjustment base 703 along the surface of the base plate 500, so as to drive the two target lines 100 to be tensioned or retracted through the target line clamping plate 701.

[0059] In this embodiment, the target line clamping plate 701 may include two opposing clamping plates, each of which has a clamping groove in front of it, and the distance between the two clamping plates is controlled by a tightening knob, that is, the target line clamping plate 701 clamps and fixes the target line 100 through the two clamping plates. When the target line clamping plate 701 and the two target lines 100 are clamped and fixed, a slide rail may be provided on the adjustment base 703. The target line clamping plate 701 has a base, that is, the target line clamping plate 701 is slidably connected to the slide rail of the adjustment base 703 through the base. When the linear moving mechanism 702 drives the target line clamping plate 701 to reciprocate relative to the adjustment base 703, that is, on the basis of the target line fixing seat 600 fixing one end of the target line 100, the two target lines 100 can be driven to be tensioned or retracted.

[0060] In an alternative embodiment of the present invention, the target wire clamping plate 701 may include three clamping plates arranged in parallel in sequence, with two clamping grooves formed between the three clamping plates, and the two clamping grooves are used to clamp two target wires 100 respectively.

[0061] Optionally, the linear motion mechanism 702 can be of various types, such as a stepping motor, a cylinder, a hydraulic cylinder, etc., that is, the linear motion of the linear motion mechanism 702 is used to drive the target line clamping plate 701 to reciprocate relative to the adjustment base 703; in addition, the linear motion mechanism 702 can include a knob, a gear and a rack. After the target line clamping plate 701 and the adjustment base 703 complete the sliding fit, the rack is connected to the adjustment base 703, and the extension direction of the rack is the same as the extension direction of the slide rail of the adjustment base 703. The gear can be located inside the target line clamping plate 701, and the gear and the target line clamping plate 701 are rotatably connected. The gear is meshed with the rack. The knob passes through the side wall of the target line clamping plate 701 and is connected to the gear. When the knob drives the gear to rotate, the gear can rotate along the extension direction of the rack. The target line clamping plate 701 is moved relative to the slide rail of the adjustment base 703 by the rotation of the gear and rack. The movement direction of the target line clamping plate 701 is controlled by controlling the direction of the knob.

[0062] It should be noted that, although the two target lines 100 will be brought closer to each other during the tensioning process, since the distance between the two target lines 100 is in the micron range during the assembly process, in order to ensure that the two target lines 100 can be more closely fitted and close, in a preferred embodiment of the present invention, a first target line positioning mechanism 800 is further included; the first target line positioning mechanism 800 is located between the specimen fixing seat 200 and the target line fixing seat 600, and the first target line positioning mechanism 800 includes a first line moving body 801, and the first line moving body 801 has a straight wall parallel to the extension direction of the target line 100, and the first line moving body 801 can reciprocate in a direction relatively close to or relatively away from the target line 100, so that the straight wall can contact the two target lines 100, further making the two target lines 100 closely attached.

[0063] Furthermore, the first target wire positioning mechanism 800 has a first positioning channel, and the first target wire positioning mechanism 800 is clamped on the outside of the two target wires 100 through the first positioning channel. The first target wire positioning mechanism 800 can reciprocate relative to the substrate 500 in a direction perpendicular to the extension direction of the target wires 100 to drive the two target wires 100 to move relative to each other, so that the two target wires 100 are in contact with the two side surfaces of the feeler gauge 400.

[0064] In this embodiment, the first target line positioning mechanism 800 can be clamped on the outside of the two target lines 100 using the first positioning channels. By adjusting the spacing of the first positioning channels, the first target line positioning mechanism 800 can be used to clamp the two target lines 100 on both sides perpendicular to the extension direction of the target lines 100, thereby better bringing the two target lines 100 closer to each other. The feeler gauge 400 can then be used to set the distance between them within a fixed range, thereby improving the assembly accuracy of the target lines 100.

[0065] In a preferred embodiment of the present invention, the first target line positioning mechanism 800 further includes a first top line body 802; the first line moving body 801 and the first top line body 802 are respectively clamped on both sides of the two target lines 100, and the first line moving body 801 and the first top line body 802 can reciprocate in a direction of relatively approaching or relatively moving away from each other. The first line moving body 801 and the first top line body 802 can respectively abut against the two target lines 100 to drive the two target lines 100 to be clamped on both sides of the feeler gauge 400 in a relatively close manner.

[0066] In this embodiment, the first line-moving body 801 and the first top line body 802 serve as structures on the outer sides of the two target lines 100, respectively. The first line-moving body 801 can reciprocate relative to the substrate 500 in a direction perpendicular to the extension direction of the target lines 100. Similarly, the first top line body 802 can reciprocate relative to the substrate 500 in a direction perpendicular to the extension direction of the target lines 100. That is, when the first line-moving body 801 and the first top line body 802 move in a direction approaching each other, the first line-moving body 801 and the first top line body 802 respectively form an extrusion force on the two target lines 100, so that the two target lines 100 can be clamped more tightly on both sides of the feeler gauge 400, ensuring that the two target lines 100 are fixedly assembled on the surface of the test piece 300 at a preset distance.

[0067] In a preferred embodiment of the present invention, the first line moving body 801 includes a first moving seat 811 and a first driving part 821, and the first top line body 802 includes a first top line seat 812 and a second driving part 822; a first groove structure 8111 is provided on the first moving seat 811, and a first top line structure 8121 corresponding to the first groove structure 8111 is provided on the first top line seat 812. The first driving part 821 is used to drive the first moving seat 811 to reciprocate relative to the substrate 500, and the second driving part 822 is used to drive the first top line seat 812 to reciprocate relative to the substrate 500. The two target lines 100 are used to cooperate with the inner wall of the first groove structure 8111 and the first top line structure 8121 respectively, so as to drive the two target lines 100 to be pressed close together through the mutual plug-in cooperation of the first groove structure 8111 and the first top line structure 8121.

[0068] In this embodiment, in order to ensure the assembly of the first movable seat 811 and the first top line seat 812, a groove and a top line staggered assembly structure are formed between the first movable seat 811 and the first top line seat 812, wherein the first movable seat 811 can be provided with a first groove structure 8111, and the first top line seat 812 can be provided with a first top line structure 8121 corresponding to the first groove structure 8111, or the first movable seat 811 can be provided with a first top line structure 8121, and the first top line seat 812 can be provided with a first top line structure 8121 corresponding to the first groove structure 8111. The first groove structure 8111 of the first push wire structure 8121, when the first movable seat 811 is driven by the first driving portion 821 and the first push wire seat 812 is driven by the second driving portion 822, moves in a direction toward each other, and during the process of the first push wire structure 8121 being inserted into the first groove structure 8111, the two target wires 100 can be better compressed, that is, a force is applied to the target wires 100 by means of offset compression, thereby better ensuring that the two target wires 100 are tightly fitted to both sides of the feeler gauge 400.

[0069] Optionally, the first driving part 821 and the second driving part 822 can be of various types, such as: a stepping motor, a cylinder, a hydraulic cylinder, etc. Taking the first driving part 821 as an example, the first driving part 821 is used to drive the first movable seat 811 to move back and forth relative to the base plate 500 by means of a linear movement. In addition, the first driving part 821 can include a knob, a gear and a rack. The first movable seat 811 can be slidably assembled with the base plate 500 by means of a slide rail and a slide groove. The rack is connected to the base plate 500, and the extension direction of the rack is perpendicular to the extension direction of the target line 100. The gear can be located inside the first movable seat 811, and the gear and the first movable seat 811 are rotatably connected. The gear and the rack are meshed and connected. The knob passes through the side wall of the first movable seat 811 and is connected to the gear. When the knob drives the gear to rotate, the gear can rotate along the extension direction of the rack. The rotation of the gear and rack causes the first movable seat 811 to move relative to the slide rail of the base plate 500, and the movement direction of the first movable seat 811 is controlled by controlling the direction of the knob.

[0070] In a preferred embodiment of the present invention, the first line moving body 801 includes a first movable seat 811 and a first driving part 821, and the first top line body 802 includes a first top line seat 812 and a second driving part 822; the first movable seat 811 has a first straight wall corresponding to the target line 100, and the first top line seat 812 has a second straight wall corresponding to the first straight wall. The first driving part 821 is used to drive the first movable seat 811 to reciprocate relative to the substrate 500, and the second driving part 822 is used to drive the first top line seat 812 to reciprocate relative to the substrate 500. The two target lines 100 are used to respectively abut and cooperate with the first straight wall and the second straight wall, so as to drive the two target lines 100 to be pressed close to each other through the first straight wall and the second straight wall approaching each other.

[0071] In this embodiment, the first movable seat 811 and the first top-line seat 812 are clamped by means of straight walls. That is, when the first movable seat 811 is driven by the first driving portion 821 and the first top-line seat 812 is driven by the second driving portion 822 to move toward each other, the first straight wall and the second straight wall are in contact with each other, so that the two target lines 100 can be closely attached to each other. That is, the first straight wall and the second straight wall exert a force on the target lines 100 by squeezing each other, thereby better ensuring that the two target lines 100 are closely attached to both sides of the feeler gauge 400.

[0072] In a preferred embodiment of the present invention, a second target line positioning mechanism 900 is further included; the second target line positioning mechanism 900 is located between the specimen fixing seat 200 and the target line adjustment seat 700, and the second target line positioning mechanism 900 has a second positioning channel. The second target line positioning mechanism 900 is clamped to the outside of the two target lines 100 through the second positioning channel. The second target line positioning mechanism 900 can reciprocate relative to the base plate 500 in a direction perpendicular to the extension direction of the target lines 100 to drive the two target lines 100 to move relative to each other, so that the two target lines 100 are in contact with the two side surfaces of the feeler gauge 400; the second target line positioning mechanism 900 has the same structure as the first target line positioning mechanism 800.

[0073] In this embodiment, since the first target line positioning mechanism 800 can provide a clamping force on the target line 100 on one side of the specimen fixing seat 200, in order to ensure that the two target lines 100 are completely aligned with the surface of the feeler gauge 400, a second target line positioning mechanism 900 is arranged between the specimen fixing seat 200 and the target line adjustment seat 700. The second target line positioning mechanism 900 and the first target line positioning mechanism 800 can be arranged symmetrically with respect to the center of the feeler gauge 400. The second target line positioning mechanism 900 can clamp the outside of the two target lines 100 using the second positioning channel. By adjusting the spacing of the second positioning channel, the second target line positioning mechanism 900 can clamp the two target lines 100 on both sides perpendicular to the extension direction of the target lines 100, thereby better bringing the two target lines 100 into close proximity with each other. The feeler gauge 400 then sets the distance between them within a fixed range, thereby improving the assembly accuracy of the target lines 100.

[0074] It should be noted that since the second target line positioning mechanism 900 has the same structure as the first target line positioning mechanism 800, that is, the second target line positioning mechanism 900 includes a second line moving body 901 and a second top line body 902; the second line moving body 901 and the second top line body 902 are respectively clamped on both sides of the two target lines 100, and the second line moving body 901 and the second top line body 902 can move back and forth in a direction of relative proximity or relative distance, and the second line moving body 901 and the second top line body 902 can respectively abut against the two target lines 100 to drive the two target lines 100 to be clamped on both sides of the feeler gauge 400 in a relatively close manner. In this embodiment, the second line-moving body 901 and the second top line body 902 serve as structures on the outside of the two target lines 100 respectively. The second line-moving body 901 can reciprocate relative to the substrate 500 in a direction perpendicular to the extension direction of the target lines 100. Similarly, the second top line body 902 can reciprocate relative to the substrate 500 in a direction perpendicular to the extension direction of the target lines 100. That is, when the second line-moving body 901 and the second top line body 902 move in a direction approaching each other, the second line-moving body 901 and the second top line body 902 respectively form an extrusion force on the two target lines 100, so that the two target lines 100 can be clamped more tightly on both sides of the feeler gauge 400, ensuring that the two target lines 100 are fixedly assembled on the surface of the test piece 300 at a preset distance.

[0075] Optionally, the second target line positioning mechanism 900 can also have multiple application modes.

The third driving part is used to drive the second moving seat to reciprocate relative to the substrate 500, and the fourth driving part is used to drive the second top line seat to reciprocate relative to the substrate 500. The two target lines 100 are used to respectively cooperate with the inner wall of the second groove structure and the second top line structure, so as to drive the two target lines 100 to be pressed close together through the mutual plug-in cooperation of the second groove structure and the second top line structure.

[0076] In this embodiment, in order to ensure the assembly of the second movable seat and the second top line seat, a groove and a top line staggered assembly structure are formed between the second movable seat and the second top line seat, wherein the second movable seat can be provided with a second groove structure, and the second top line seat can be provided with a second top line structure corresponding to the second groove structure, or the second movable seat can be provided with a second top line structure, and the second top line seat can be provided with a second groove structure corresponding to the second top line structure. When the second movable seat is driven by the third driving part and the second top line seat is driven by the fourth driving part, the two move in a direction approaching each other, and the second top line structure is inserted into the second groove structure during the process, the two target lines 100 can be better pressed, that is, a force is provided to the target lines 100 by means of staggered pressing, thereby better ensuring that the two target lines 100 are tightly fitted to both sides of the feeler gauge 400.

[0077] Optionally, the third driving unit and the fourth driving unit can be of various types, such as a stepping motor, a cylinder, a hydraulic cylinder, etc. Taking the third driving unit as an example, the linear movement of the third driving unit drives the second movable seat to move back and forth relative to the substrate 500; in addition, the third driving unit

[0078] The second movable seat can include a knob, a gear and a rack. The second movable seat can be slidably assembled with the base plate 500 by means of a slide rail and a slide groove. The rack is connected to the base plate 500, and the extension direction of the rack is perpendicular to the extension direction of the target line 100. The gear can be located inside the second movable seat, and the gear and the second movable seat are rotatably connected. The gear and the rack are meshed and connected.

[0079] The second movable base is rotated in the extension direction, and the second movable base is moved relative to the slide rail of the base plate 5000 by rotating the gear rack, and the moving direction of the second movable base is controlled by turning the control knob.

[0080] In a preferred embodiment of the present invention, the second line moving body 901 includes a second moving seat and a third driving part, and the second top line body 902 includes a second top line seat and a fourth driving part; the second moving seat has a second straight wall corresponding to the target line 100, and the second top line seat has a second straight wall corresponding to the second straight wall.

[0081] The second top line wall, the third driving part is used to drive the second movable seat to move back and forth relative to the base plate 500, the fourth driving part is used to drive the second top line seat to move back and forth relative to the base plate 500, and the two target lines 100 are used to abut and cooperate with the second straight wall and the second top line wall respectively, so as to drive the two target lines 100 to be pressed and approached by the second straight wall and the second top line wall approaching each other.

[0082] In this embodiment, the second movable seat and the second top-line seat are clamped by means of straight walls. That is, when the second movable seat is driven by the third driving unit and the second top-line seat is driven by the fourth driving unit, the two move toward each other. As a result, the second straight wall and the second top-line wall fit together, so that the two target lines 100 can be closely fitted. That is, the second straight wall and the second top-line wall squeeze each other to provide a force on the target lines 100, thereby better ensuring that the two target lines 100 fit closely with both sides of the feeler gauge 400.
