Description

Technical Field

[0001] The present application relates to the technical field of fixtures, and in particular to a measuring fixture for shaft sleeve parts. Background Art

[0002] A three-dimensional coordinate measuring machine is a high-precision measuring instrument that can determine the spatial position of an object through three mutually perpendicular coordinate axes (X, Y, and Z), thereby measuring the size, shape, and position of the object. The working principle of a three-dimensional coordinate measuring machine is to place the object to be measured in the measuring space, obtain the coordinate position of each measuring point on the object through a contact or non-contact detection system, and then calculate the geometric size, shape, and position of the object through software.

[0003] In the manufacturing industry, three-coordinate measuring machines are used to accurately measure the geometric shape and size of workpieces. The three-coordinate measuring machine includes a workbench and a probe. A fixture is set on the top of the workbench. Before measurement, the workpiece needs to be stabilized on the top of the workbench through the fixture, and then the workpiece is measured through the side head.

[0004] However, in the current three-coordinate measurement process, the design and use of fixtures is often a tedious and time-consuming process, which usually requires multiple adjustments and clamping to complete the measurement of various aspects of the workpiece, thereby increasing the difficulty of operation for staff. Summary of the invention

[0005] In order to improve the convenience of operation of the fixture, the present application provides a measuring fixture for sleeve-type parts.

[0006] The present application provides a measuring fixture for shaft sleeve parts, which adopts the following technical solution:

[0007] A measuring fixture for shaft sleeve parts includes a support frame, a suspension is fixed on the top of the support frame, a clamping groove is penetrated through the side wall of the top of the suspension, a clamping group is provided on the outer wall of the suspension, the clamping group includes two clamping blocks, the two clamping blocks are distributed along the outer wall of the suspension, a clamping claw is adapted to clamp between the two clamping blocks, there are multiple clamping groups, and the multiple clamping groups are distributed along the circumference of the outer wall of the suspension, and the number of the clamping claws is adapted to the number of the clamping groups.

[0008] By adopting the above technical solution, when the workpiece needs to be measured by a three-coordinate measuring machine, one end of the workpiece is first passed through the clamping slot, and the suspension supports the workpiece. Then, the clamping claws are adjusted in sequence, and the operator can move the adjustment block until one end of the clamping claw abuts against the outer wall of the workpiece, and the clamping claw abuts against the intersection of the protruding plate on the outer wall of the workpiece, thereby better limiting the workpiece and reducing the shaking and instability of the workpiece, and then measuring the workpiece.

[0009] The present application limits one end of the workpiece by plugging one end of the workpiece into the clamping groove, and then limits the other end of the workpiece by adjusting the position of the clamping claw, thereby clamping the workpiece. The operation is simple and convenient, thereby improving the convenience of operation of the clamp.

[0010] Preferably, the clamping claw comprises an adjusting block, and the adjusting block is adapted to be inserted between the two clamping blocks. A connecting piece is provided at one end of the clamping group, and the connecting piece passes through the two clamping blocks and the adjusting block at the same time.

[0011] By adopting the above technical solution, under the action of the connecting piece, the connection stability between the adjustment block and the clamping group can be improved, and the situation where the adjustment block slips out from between the clamping groups can be reduced.

[0012] Preferably, an adjustment slot is formed through the top surface of the adjustment block, the extension direction of the adjustment slot is parallel to the long side of the adjustment block, and one end of the clamping member passes through the adjustment slot.

[0013] By adopting the above technical solution, under the action of the adjustment groove, the adjustment block is bendable so that the adjustment block can adjust the claw by rotating along the connecting piece. At the same time, the adjustment block can also be moved to change the position of the connecting piece in the adjustment groove, so that the claw can be better adjusted so that the claw abuts against the workpiece.

[0014] Preferably, the clamping claw further includes an abutment block, one end of which is fixed to one end of the adjustment block, and the abutment block is located on a side of the adjustment block close to the suspension.

[0015] By adopting the above technical solution, under the action of the abutment block, the abutment block can abut against the outer wall of the workpiece to limit the position of the workpiece.

[0016] Preferably, the abutment block is a triangular block, and the angle of the abutment block cross section away from one end of the adjustment block is an acute angle.

[0017] By adopting the above technical solution, the angle of the abutment block cross section away from one end of the adjustment block is an acute angle, so that the abutment block can be stuck in the angle between the outer wall of the workpiece and the protruding plate, thereby reducing damage to the workpiece.

[0018] Preferably, the number of the claws is three, and the three claws are distributed along the outer wall of the suspension.

[0019] By adopting the above technical solution, the number of claws is three, the triangle is stable, and the three claws can better limit the workpiece and reduce the situation where the workpiece deviates to one side. At the same time, it can also reduce the situation where too many claws make the steps of clamping the workpiece complicated.

[0020] Preferably, the support frame and the suspension frame are detachably connected.

[0021] By adopting the above technical solution, the support frame and the suspension are detachably connected, and when the diameter of the workpiece changes, it is convenient to replace the suspension with other sizes, thereby improving the applicability of the fixture.

[0022] Preferably, a connection groove is opened at one end of the top surface of the support frame, the bottom of the suspension frame is located in the connection groove, the bottom surface of the suspension frame abuts against the top surface of the support frame, and the side wall of the bottom of the suspension abuts against the side wall of the top of the support frame.

[0023] By adopting the above technical solution, under the action of the connecting groove, the contact area between the suspension and the support frame can be increased, and at the same time the support frame can also support the suspension, thereby improving the connection stability between the suspension and the support frame and reducing the shaking and instability between the suspension and the support frame.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the workpiece needs to be measured by a three-coordinate measuring machine, first pass one end of the workpiece through the clamping slot, and the suspension supports the workpiece. Then, adjust the clamping claws in sequence. The operator can move the adjustment block until one end of the clamping claw abuts against the outer wall of the workpiece. The clamping claw abuts against the intersection of the protruding plate on the outer wall of the workpiece, so as to better limit the workpiece and reduce the shaking and instability of the workpiece. Then measure the workpiece. This application limits one end of the workpiece by plugging one end of the workpiece into the clamping slot, and then limits the other end of the workpiece by adjusting the position of the clamping claw, thereby clamping the workpiece. The operation is simple and convenient, thereby improving the convenience of the clamp operation.

[0026] 2. Under the action of the connecting piece, the connection stability between the adjustment block and the clamping group can be improved, and the adjustment block can be reduced from slipping out from the clamping group. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.

[0032] The embodiment of the present application discloses a measuring fixture for bushing-like parts.

[0033] Referring to Figure 1 , a measuring fixture for bushing-like parts includes a support frame 1. The support frame 1 includes a base 11. The base 11 includes a fixing block 111 and a connecting block 112. There are two fixing blocks 111, and the two fixing blocks 111 are arranged relatively parallel. The connecting block 112 is fixed between the two fixing blocks 111. The connecting block 112 is located in the middle of the fixing block 111. After the connecting block 112 is assembled with the two fixing blocks 111, a "worker"-shaped structure body is formed. Mounting grooves 113 are respectively formed through the top surfaces of the two fixing blocks 111. The extending direction of the mounting grooves 113 is parallel to the long side direction of the fixing block 111. The number of mounting grooves 113 on one fixing block 111 is two, and the two mounting grooves 113 are distributed at both ends of the fixing block 111. The mounting grooves 113 correspond to the positioning holes on the top surface of the measuring instrument workbench. A fastening member (not shown in the drawings) is provided on the top surface of the fixing block 111. In the embodiment of the present application, the fastening member is a first bolt. One end of the first bolt passes through the mounting groove 113 and the positioning hole at the same time. The fixing block 111 and the workbench are fixed by the first bolt. Under the action of the mounting groove 113, the position of the base 11 on the top surface of the workbench can be adjusted.

[0034] Referring to Figure 2 , the support frame 1 further includes a support rod 2. The bottom surface of the support rod 2 is fixed on the top surface of the connecting block 112. The support rod 2 is vertically arranged in the middle of the connecting block 112. A connecting groove 21 is formed at one end of the top surface of the support rod 2, so that an "L"-shaped connecting platform is formed at the top of the support rod 2. A suspension 3 is provided at the top of the support rod 2. The bottom of the suspension 3 is located in the connecting groove 21. The bottom surface of the suspension 3 abuts against the top surface of the support rod 2. The side wall of the bottom of the suspension 3 abuts against the side wall of the top of the support rod 2. A second bolt (not shown in the drawings) is provided at the top of the support rod 2. The support rod 2 and the suspension 3 are fixed by the second bolt.

[0035] Referring to Figure 3The top of the suspension 3 is a circular structure, and a clamping group 4 is fixed on the outer wall of the suspension 3. The clamping group 4 includes two clamping blocks 41. The top surfaces of the two clamping blocks 41 are respectively penetrated with clamping holes 411. The two clamping blocks 41 are respectively fixed and clamped along the outer wall of the suspension 3. A storage space is left between the two clamping blocks 41. The number of the clamping groups 4 depends on the specific situation. In the embodiment of the present application, there are three clamping groups 4, and the three clamping groups 4 are evenly distributed along the circumference of the suspension 3.

[0036] Reference Figure 1 and Figure 3 , claws 5 are respectively provided inside the three clamping groups 4, and the claws 5 include an adjusting block 51 and an abutting block 52. An adjusting slot 511 is formed on the top surface of the adjusting block 51, and the extending direction of the adjusting slot 511 is parallel to the long side of the adjusting block 51. The adjusting block 51 is adapted to be inserted between the two clamping blocks 41, and the adjusting slot 511 corresponds to the clamping hole 411. A connecting piece is provided at one end of the clamping group 4. In the embodiment of the present application, the connecting piece is a third bolt 42 (not shown in the drawings), and one end of the third bolt 42 passes through the two clamping holes 411 and the adjusting slot 511 at the same time, thereby improving the connection stability between the adjusting block 51 and the clamping group 4 and reducing the situation where the adjusting block 51 slips out from between the clamping groups 4. A handle 43 is fixed to one end of the third bolt 42. Under the action of the handle 43, the third bolt 42 can be better rotated, thereby improving the convenience of disassembly and assembly of the third bolt 42.

[0037] The abutment block 52 is a triangular block, one end of which is fixed to one end of the adjustment block 51. The abutment block 52 is located on the side of the adjustment block 51 close to the suspension 3. The angle of the cross section of the abutment block 52 away from the end of the adjustment block 51 is an acute angle. A snap-in groove 31 is provided through the side wall of the suspension 3, so that a circular ring-shaped structure is formed on the top of the suspension 3.

[0038] Reference Figure 1 When the workpiece 6 needs to be measured by the three-dimensional coordinate measuring machine, one end of the workpiece 6 is first passed through the clamping groove 31, and the suspension 3 supports the workpiece 6. Then, the claw 5 is adjusted in turn. The operator can bend the adjustment block 51 so that the adjustment block 51 can adjust the claw 5 by rotating along the third bolt 42 until one end of the abutment block 52 abuts against the outer wall of the workpiece 6, and the abutment block 52 abuts at the intersection of the protruding plate of the outer wall of the workpiece 6, so as to better limit the workpiece 6. The three abutment blocks 52 abut along the circumference of the workpiece 6, so as to limit the workpiece 6 and reduce the shaking and instability of the workpiece 6. Then, the workpiece 6 is measured.

[0039] The present application limits one end of the workpiece 6 by plugging one end of the workpiece 6 into the clamping groove 31, and then limits the other end of the workpiece 6 by adjusting the position of the clamping claw 5, thereby clamping the workpiece 6. The operation is simple and convenient, thereby improving the convenience of operation of the clamp.
