Description

Technical Field

[0001] This application relates to the field of Kunpeng precision technology, specifically to a multi-functional integrated fixture for positioning and measurement. Background Technology

[0002] With the rapid development of modern manufacturing, fixture technology has become an indispensable part of the production line. Multifunctional fixture technology, as a leader in this field, has received widespread attention and application due to its high efficiency, flexibility, and versatility. As the name suggests, multifunctional fixture technology refers to a type of fixture with multiple functions. It not only meets the traditional requirements for workpiece clamping and positioning but also adapts to different workpieces, processes, and production environments, enabling rapid changeover, adjustment, and positioning. This technology has greatly improved the flexibility and efficiency of production lines. Multifunctional fixture technology will bring more efficient, flexible, and environmentally friendly production methods to the manufacturing industry, driving its development to a higher level. Multifunctional fixtures have a wide range of applications. In the fields of machining and measurement, fixtures are widely used to fix workpieces for precise machining or measurement.

[0003] Most existing fixtures are single-function, only capable of clamping, and cannot perform measurement or positioning while clamping. Therefore, it is necessary to first use the fixture to fix the workpiece, and then use a separate measuring tool to measure its position and size. This method cannot meet the needs of clamping, positioning and measurement at the same time. It is necessary to repeatedly pick up and drop the measuring tool or add additional measuring equipment to repeatedly measure the size of the workpiece, resulting in a cumbersome and inefficient processing and measurement process. Utility Model Content

[0004] The purpose of this application is to provide a multi-functional integrated fixture for positioning and measurement, in order to solve the problem in the background art that requires first using a fixture to fix the workpiece and then using a separate measuring tool to measure its position and size. This method cannot simultaneously meet the needs of clamping, positioning and measurement, and requires repeatedly taking out the measuring tool or adding additional measuring equipment to repeatedly measure the size of the workpiece, resulting in a cumbersome and inefficient processing and measurement process.

[0005] To achieve the above objectives, this application provides the following technical solution: a multifunctional integrated clamp for positioning and measurement, comprising a clamping base, a positioning part, a reflecting part, and a measuring part. The positioning part is disposed inside the clamping base, the reflecting part is disposed above the positioning part, and the measuring part is disposed above the clamping base. The measuring part includes a support frame fixed to the top surface of the clamping base. One-way ball screws are rotatably connected to both sides inside the support frame. A synchronous gear is connected to the top of the one-way ball screw. A synchronous toothed belt is meshed on the outer side of the synchronous gear. A rotating handle is fixedly connected to the center of the side of the synchronous gear away from the one-way ball screw. A lifting sleeve is threaded around the outer circumference of the one-way ball screw. A connecting rod is fixedly disposed on the outer wall of the lifting sleeve. A mounting box is connected to the end of the connecting rod away from the lifting sleeve. An infrared rangefinder is fixedly connected to the inner wall of the mounting box.

[0006] By adopting the above technical solution, a measuring tool whose height can be adjusted according to the size of the workpiece can be constructed.

[0007] Preferably, the positioning part includes a clamping positioning block slidably connected to the inner bottom surface of the clamping base, a threaded rod rotatably connected to the side of the clamping positioning block away from the measuring part, the end of the threaded rod away from the clamping positioning block extending to the outside of the clamping base, and two sets of positioning side plates slidably connected to the side wall of the clamping positioning block near the measuring part.

[0008] By adopting the above technical solution, rotating the threaded rod is used to push the clamping and positioning block to clamp and fix the workpiece.

[0009] Preferably, the reflective part includes a fixed frame fixedly connected to the top surface of the clamping positioning block, a reflective baffle slidably connected to the inner side wall of the fixed frame, and a movable slot provided on the outer side wall of the fixed frame, the movable slot communicating with the inner side of the fixed frame.

[0010] By adopting the above technical solution, the reflective baffle can reflect the infrared light emitted by the infrared rangefinder.

[0011] Preferably, the clamping base has a storage slot inside, which is connected to the outside of the clamping base, and the clamping positioning block and the positioning side plate are both disposed inside the storage slot.

[0012] By adopting the above technical solution, the interior of the storage slot is used to place the workpiece that needs to be clamped and measured.

[0013] Preferably, the movable slot is provided with two sets of screws. One end of the screw extends to the inner side of the fixed frame and is fixedly connected to the outer side wall of the reflective baffle. The other end of the screw extends to the outer side of the fixed frame. A nut sleeve is fitted around the outer circumference of the screw.

[0014] By adopting the above technical solution, the height of the reflective baffle can be adjusted to match the height of the infrared rangefinder.

[0015] Preferably, there are two sets of unidirectional ball screws and synchronous gears, which are symmetrically distributed on the vertical central axis of the support frame. The rotating handle is located above one set of synchronous gears, and the bottom end of the rotating handle extends into the interior of the support frame and is fixedly connected to the center of the top surface of the synchronous gear.

[0016] By adopting the above technical solution, the synchronous gear drives the unidirectional ball screw to rotate when it rotates.

[0017] Preferably, the lifting sleeve has a threaded groove inside, and the one-way ball screw passes through the inside of the threaded groove and is threadedly connected to the inside of the threaded groove.

[0018] By adopting the above technical solution, the lifting sleeve block is pushed up and down when it rotates.

[0019] Preferably, the support frame has several sets of insertion slots on its top surface near the rotating handle. The several sets of insertion slots are equidistantly distributed around the circumference of the rotating handle. An insertion rod is inserted into the inside of the rotating handle. The bottom end of the insertion rod extends into the inside of a set of insertion slots and is inserted into the inside of the insertion slot.

[0020] By adopting the above technical solution, the rotating handle can be fixed after rotation.

[0021] Compared with the prior art, the beneficial effects of this application are as follows: By placing the workpiece to be clamped and measured inside the clamping base, and continuously rotating the rotating handle, the rotating handle drives the synchronous gear to rotate. At this time, the synchronous belt drives two sets of synchronous gears to rotate synchronously. The synchronous gear drives the one-way ball screw to rotate. During the rotation of the one-way ball screw, the lifting sleeve block moves upward. When the rotating handle is rotated in the opposite direction, the lifting sleeve block can be moved downward. The lifting sleeve block drives the connecting rod, mounting box, and infrared rangefinder to adjust the height, which is convenient for adjustment according to the height of the workpiece. After the rotating positioning part positions and clamps the workpiece, the infrared switch of the infrared rangefinder is activated. With the cooperation of the reflector, the specific size of the workpiece is measured and displayed in real time. This constitutes a reflector and measuring part that can adapt to various workpiece sizes, which is convenient for height adjustment according to the specific size of the workpiece. After the workpiece is clamped and fixed, the specific size of the workpiece is measured and displayed in real time through the infrared rangefinder. It has the integrated functions of clamping, auxiliary positioning, and measurement, which simplifies the processing and measurement process and improves the accuracy and efficiency of processing and measurement.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] Example 1

[0032] Please see Figure 1-6This embodiment provides a multi-functional integrated fixture for positioning and measurement: a multi-functional integrated fixture for positioning and measurement includes a clamping base 1, a positioning part 2, a reflecting part 3, and a measuring part 4. The clamping base 1 has an internal storage groove 101 that communicates with the outside of the clamping base 1. The inside of the storage groove 101 is used to place the workpiece to be clamped. A clamping positioning block 201 and a positioning side plate 203 are both disposed inside the storage groove 101. The positioning part 2 includes a clamping positioning block 201 slidably connected to the bottom surface inside the clamping base 1. A threaded rod 202 is connected to the side of the clamping positioning block 201 away from the measuring part 4 via a bearing. The end of the threaded rod 202 away from the clamping positioning block 201 passes through the clamping base 1. Inside, and extending to the outside of the clamping base 1, the end of the threaded rod 202 away from the clamping positioning block 201 is also provided with a cylindrical handle. When the cylindrical handle is held and rotated continuously, the end of the threaded rod 202 near the clamping positioning block 201 can push the clamping positioning block 201 to slide inside the storage slot 101, thereby clamping and fixing the workpiece placed inside the storage slot 101. Two sets of positioning side plates 203 are slidably connected to the side wall of the clamping positioning block 201 near the measuring part 4. The positioning side plates 203 are set on both sides of the workpiece. The side wall of the clamping positioning block 201 is provided with a sliding groove. By adjusting the lateral position of the positioning side plates 203 until the positioning side plates 203 are in contact with the side wall of the workpiece, the two sides of the workpiece can be initially positioned and protected.

[0033] Example 2

[0034] Please see Figure 1-6The measuring unit 4 is positioned above the clamping base 1. The measuring unit 4 includes a support frame 401 screwed to the top surface of the clamping base 1. One-way ball screws 402 are connected to both sides of the support frame 401 via bearings. The support frame 401 has a hollow interior. A synchronous gear 403 is screwed to the top of each one-way ball screw 402. Two sets of one-way ball screws 402 and synchronous gears 403 are provided and symmetrically distributed along the vertical central axis of the support frame 401. A rotating handle 405 is positioned above one set of synchronous gears 403. The bottom end of the rotating handle 405 extends into the interior of the support frame 401 and is screwed to the center of the top surface of the synchronous gear 403. Connect, hold and rotate the handle 405 continuously. The handle 405 drives a set of synchronous gears 403 to rotate. The meshing of the synchronous belt 404 with the synchronous gears 403 drives another set of synchronous gears 403 to rotate synchronously. At this time, the two sets of synchronous gears 403 drive the one-way ball screw 402 to rotate. The synchronous belt 404 is meshed on the outer side of the synchronous gear 403. The handle 405 is screwed to the center of the side of the synchronous gear 403 away from the one-way ball screw 402. A lifting sleeve 406 is threaded around the outer circumference of the one-way ball screw 402. When the one-way ball screw 402 rotates, it pushes the lifting sleeve 406 to move vertically upwards. When the handle 405 is gripped... When the handle 405 rotates in the opposite direction, the one-way ball screw 402 pushes the lifting sleeve 406 to move vertically downwards. The lifting sleeve 406 has a threaded groove 409 inside, through which the one-way ball screw 402 passes and is threadedly connected to the inner side of the groove 409. A connecting rod 412 is screwed to the outer wall of the lifting sleeve 406. The end of the connecting rod 412 away from the lifting sleeve 406 is connected to a mounting box 407. When the lifting sleeve 406 adjusts its height, it drives the connecting rod 412 to move synchronously. This, in turn, adjusts the height of the infrared rangefinder 408 via the mounting box 407, adapting to workpieces of different sizes and preventing issues caused by oversized workpieces affecting infrared ranging. The light emitted by the infrared rangefinder 408 is blocked. The infrared rangefinder 408 is screwed onto the inner wall of the mounting box 407. The infrared rangefinder 408 has a light emitter and a photodiode as an infrared photoelectric detection and conversion device on the side wall near the workpiece. When the infrared light is emitted to the surface of the reflective baffle 302, the reflective baffle 302 reflects the light. The photodiode converts the received light signal into an electrical signal to achieve the purpose of measuring the workpiece. The infrared rangefinder 408 is also equipped with a display screen, which can display the measured data in real time. The outer wall of the infrared rangefinder 408 is also equipped with a data interface to facilitate data export, analysis and processing.

[0035] The support frame 401 has several sets of insertion slots 410 on its top surface near the rotating handle 405. These slots are evenly distributed around the circumference of the rotating handle 405. An insertion rod 411 is inserted into the inside of the rotating handle 405. The bottom end of the insertion rod 411 extends into the inside of one of the insertion slots 410 and is inserted into the inside of the slot. By grasping the top of the insertion rod 411 and moving it upwards until it moves out of the insertion slot 410, the limiting measures on the rotating handle 405 are released, making it easier to rotate the rotating handle 405 to adjust the position and height of the infrared rangefinder 408. When the insertion rod 411 is held downwards and vertically inserted into the rotating handle 405 and the inside of the insertion slot 410, the position of the rotating handle 405 is fixed.

[0036] Example 3

[0037] Please see Figure 1-6 The reflective part 3 includes a fixed frame 301 screwed to the top surface of the clamping and positioning block 201. A reflective baffle 302 is slidably connected to the inner wall of the fixed frame 301. When the reflective baffle 302 is pushed up and down, its height can be adjusted to match the infrared rangefinder 408, facilitating the reflection of infrared light emitted by the infrared rangefinder 408 and preventing the workpiece from being too large and obstructing the reflective part 3 and the measuring part 4. A movable slot 303 is provided on the outer wall of the fixed frame 301, which communicates with the inner side of the fixed frame 301. Two sets of screws 304 are provided inside the movable slot 303. One end of the screw 304 extends to the inner side of the fixing frame 301 and is welded to the outer wall of the reflective baffle 302. When the reflective baffle 302 slides up and down, it drives the screw 304 to move synchronously on the outer side of the fixing frame 301. The other end of the screw 304 extends to the outer side of the fixing frame 301. A nut sleeve 305 is fitted around the outer circumference of the screw 304. Hold the nut sleeve 305 and rotate it continuously until the nut sleeve 305 is in close contact with the outer wall of the fixing frame 301, thus fixing the position of the reflective baffle 302. When the nut sleeve 305 is rotated in the opposite direction, the fixing measures on the reflective baffle 302 can be released, making it easy to readjust the height position of the reflective baffle 302.

[0038] Working principle: First, place the workpiece to be clamped and measured inside the storage slot 101, adjust the lateral position of the positioning side plate 203 until the positioning side plate 203 is in contact with the side wall of the workpiece to perform initial positioning, then grasp the top of the insertion rod 411 and move it upward until it moves out of the insertion slot 410, and release the limiting measures of the rotating handle 405.

[0039] Next, hold the rotating handle 405 and rotate it continuously. The rotating handle 405 drives the synchronous gear 403 to rotate continuously. At this time, the synchronous belt 404 drives the two sets of synchronous gears 403 to rotate synchronously. The synchronous gear 403 drives the one-way ball screw 402 to rotate. During the rotation of the one-way ball screw 402, it drives the lifting sleeve block 406 to move upward. When you hold the rotating handle 405 and rotate it in the opposite direction, it can drive the lifting sleeve block 406 to move downward.

[0040] Finally, the lifting sleeve 406 drives the connecting rod 412, mounting box 407, and infrared rangefinder 408 to adjust their height. This facilitates adjustment based on the workpiece height and prevents the workpiece from blocking the infrared light from the infrared rangefinder 408 due to excessive size. Simultaneously, the insertion rod 411 is held vertically downwards and inserted into the rotating handle 405 and a set of insertion slots 410 to fix the position of the rotating handle 405. The reflective baffle 302 is then pushed up and down to adjust its height until it aligns with the infrared rangefinder. With the 408 matching, hold the nut sleeve 305 and rotate it continuously until the nut sleeve 305 is in close contact with the outer wall of the fixing frame 301, fixing the position of the reflective baffle 302. Then, hold the threaded rod 202 and rotate it continuously. The positioning side plate 203 pushes the workpiece to be in close contact with the inner wall of the storage slot 101. Activate the infrared switch of the infrared rangefinder 408. With the cooperation of the reflective baffle 302, measure the specific size of the workpiece. Then, collect the measurement data on the display screen of the infrared rangefinder 408 to complete the work.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
