Description

Technical Field

[0001] This utility model relates to the field of machine tool processing auxiliary equipment technology, specifically a positioning device for machine tool processing. Background Technology

[0002] Machine tool positioning aims to ensure that the workpiece has the correct position and orientation on the machine tool, thereby ensuring machining accuracy and stability. This is the core foundation for achieving high-quality production in modern manufacturing. In the field of precision machining, even slight positional deviations of the workpiece can lead to out-of-tolerance critical dimensions, affecting product performance and service life. Precise positioning enables the cutting tool to contact the workpiece according to a preset trajectory, ensuring that machining parameters such as hole diameter, flatness, and contour meet design standards, avoiding scrap rates caused by positioning errors, and improving enterprise production efficiency. At the same time, stable positioning can reduce vibration and impact during machine tool machining, which not only protects the machine tool equipment and extends its service life, but also reduces cutting noise and improves the workshop working environment. Existing machine tool positioning devices have many shortcomings. For example, some positioning devices have simple structures and only use a few fixed positioning points to position the workpiece, which is difficult to meet the positioning requirements of complex-shaped workpieces and has low positioning accuracy. Some positioning devices have poor versatility and can only be adapted to workpieces of specific specifications. When processing workpieces of different sizes and shapes, it is necessary to frequently change the positioning device, which is cumbersome and increases production costs. In addition, some positioning devices have uneven clamping force distribution on the workpiece during the positioning process, which can easily lead to workpiece deformation and affect machining accuracy. Therefore, we propose a positioning device for machine tool processing. Utility Model Content

[0003] (I) Technical Problems Solved In view of the shortcomings of the existing technology, this utility model provides a positioning device for machine tool processing, which solves many shortcomings of existing machine tool processing positioning devices. For example, some positioning devices have simple structures and only use a few fixed positioning points to position the workpiece, which is difficult to meet the positioning requirements of complex-shaped workpieces and has low positioning accuracy. Some positioning devices have poor versatility and can only be adapted to workpieces of specific specifications. When processing workpieces of different sizes and shapes, it is necessary to frequently change the positioning device, which is cumbersome and increases production costs. In addition, some positioning devices have uneven distribution of clamping force on the workpiece during the positioning process, which can easily lead to workpiece deformation and affect the processing accuracy.

[0004] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: A positioning device for machine tool processing includes a machine base. Multiple sets of positioning mounting holes are provided on the left and right sides of the machine base. Positioning components are provided on the front and rear sides of the machine base, and fixing components are provided on the positioning components. The positioning components include positioning side plates and two sets of square sleeves provided on the front and rear sides of the machine base. Fixing ears are fixedly installed at both ends of the two sides of the two sets of positioning side plates, and locking holes adapted to the positioning mounting holes are opened on the surface of the fixing ears. T-shaped sliding grooves are opened on the top of the two sets of positioning side plates.

[0005] Furthermore, both ends of the two sets of T-shaped slides are slidably connected to T-shaped sliders, and the surfaces of the four sets of T-shaped sliders are fixedly mounted with connecting rods.

[0006] Furthermore, the ends of the four sets of connecting rods away from the T-shaped groove are respectively inserted into the two ends of the two sets of square sleeves. The surfaces of the square sleeves and connecting rods are provided with several threaded holes that are evenly distributed.

[0007] Furthermore, the square sleeve and the connecting rod are fixedly connected by a locking bolt passing through a threaded hole.

[0008] Furthermore, the fixing assembly includes four sets of fixing discs fixedly installed on the surface of the four sets of connecting rods near the positioning side plate. Each of the four sets of fixing discs has a pin inserted inside one side, and each of the four sets of pins has a swing rod rotatably connected to its circumferential surface.

[0009] Furthermore, the end of the swing rod away from the fixed plate is internally threaded with a threaded rod, the bottom of the threaded rod is fixedly mounted with a fixed base plate, and the top of the threaded rod is fixedly mounted with a rotating block.

[0010] Furthermore, a rubber pad is fixedly installed on the bottom of the fixed chassis, and the fixed chassis does not contact the positioning side plate.

[0011] (III) Beneficial Effects This utility model provides a positioning device for machine tool processing, which has the following beneficial effects: 1. By setting up positioning components, multiple sets of positioning mounting holes are opened on the left and right sides of the machine tool, which, together with the locking holes on the fixing ears, allow for convenient adjustment of the position of the positioning side plate on the machine tool. At the same time, the sliding connection between the T-shaped slide groove on the top of the positioning side plate and the T-shaped slider allows the connecting rod to move freely within the T-shaped slide groove. The square sleeve and the connecting rod are fixedly connected by locking bolts passing through threaded holes. The insertion length of the square sleeve on the connecting rod can be precisely adjusted according to actual needs, changing the position of the fixing component on the positioning side plate. This comprehensive and flexible adjustment mechanism can efficiently adapt to the positioning needs of workpieces of different specifications and shapes, greatly improving the versatility of the machine tool processing positioning device.

[0012] 2. By setting a fixing component, the fixing plate is fixedly installed on the connecting rod. The pin inserted inside one side is rotatably connected to the swing rod, so that the swing rod can flexibly rotate and adjust the angle according to the shape of the workpiece and the clamping position requirements. After the angle of the swing rod is adjusted, the rotating block is rotated to drive the threaded rod to rotate, so that the fixing plate moves downward until the rubber pad at the bottom of the plate is tightly attached to the surface of the workpiece. The rubber pad has good friction and elasticity, which can provide stable clamping force while avoiding damage to the surface of the workpiece. At the same time, it can effectively prevent the workpiece from shifting or shaking during the machine tool processing, thus ensuring the machining accuracy in all aspects.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1 to 5This utility model provides a technical solution: a positioning device for machine tool processing, including a machine base 1. Multiple sets of equally spaced positioning mounting holes 2 are provided on both the left and right sides of the machine base 1. Positioning components 3 are provided on the front and rear sides of the machine base 1, and fixing components 4 are provided on the positioning components 3. The positioning components 3 include positioning side plates 301 and two sets of square sleeves 306 disposed on the front and rear sides of the machine base 1. Fixing ears 302 are fixedly installed at both ends of the two sides of the two sets of positioning side plates 301, and the surface of the fixing ears 302 is provided with locking mechanisms adapted to the positioning mounting holes 2. The top of both sets of positioning side plates 301 is provided with T-shaped slide grooves 303. Multiple sets of positioning mounting holes 2 are provided on the left and right sides of the machine base 1, providing flexible adjustment points for the installation of the positioning side plates 301. By cooperating with the locking holes on the surface of the fixing ears 302, the position of the positioning side plates 301 on the machine base 1 can be easily adjusted to adapt to the positioning requirements of workpieces of different sizes. The positioning side plates 301 are set on the front and rear sides of the surface of the machine base 1. The T-shaped slide grooves 303 on their tops provide a sliding track for the T-shaped sliders 304, which is the key structure for realizing the lateral adjustment of the positioning assembly 3.

[0017] Both ends of the two sets of T-shaped slide grooves 303 are slidably connected to T-shaped sliders 304. Connecting rods 305 are fixedly installed on the surfaces of the four sets of T-shaped sliders 304. The ends of the four sets of connecting rods 305 away from the T-shaped slide grooves 303 are respectively inserted into the two ends of the two sets of square sleeves 306. The surfaces of the square sleeves 306 and the connecting rods 305 are provided with several threaded holes 308 distributed at equal intervals. The square sleeves 306 and the connecting rods 305 are fixedly connected by locking bolts 307 passing through the threaded holes 308. The threaded holes 308 on the surfaces of the square sleeves 306 and the connecting rods 305, together with the locking bolts 307, can be used to precisely adjust the insertion length of the square sleeves 306 on the connecting rods 305 according to actual needs, thereby changing the lateral spacing of the fixing components 4.

[0018] The fixing component 4 includes four fixing plates 401 fixedly installed on the surface of one end of the four connecting rods 305 near the positioning side plate 301. Each of the four fixing plates 401 has a pin 403 inserted into its interior. Each of the four pins 403 has a swing rod 402 rotatably connected to its circumferential surface. The pins 403 are fixedly installed on the connecting rods 305, providing a mounting base for the pins 403. The pins 403 are rotatably connected to the swing rods 402, allowing the swing rods 402 to rotate flexibly around the pins 403. The angle of the swing rods 402 can be adjusted according to the shape of the workpiece and the clamping position requirements to better fit the workpiece surface for clamping operations.

[0019] The swing rod 402 has a threaded rod 404 internally connected to the end away from the fixed plate 401. A fixed base 405 is fixedly installed at the bottom of the threaded rod 404, and a rotating block 406 is fixedly installed at the top of the threaded rod 404. A rubber pad is fixedly installed at the bottom of the fixed base 405, and the fixed base 405 does not contact the positioning side plate 301. The rubber pad at the bottom of the fixed base 405 has good friction and elasticity. When it is in close contact with the workpiece surface, it can provide a stable clamping force and avoid damage to the workpiece surface. At the same time, the fixed base 405 does not contact the positioning side plate 301, which effectively prevents the two from interfering with each other during the clamping process and ensures the stability of the clamping operation.

[0020] The detailed description of known functions and components is omitted in this disclosure. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments.

[0021] In summary, the operating steps of this positioning device for machine tool processing are as follows; When using the positioning device for machining on this machine tool, first, according to the workpiece size, use the positioning mounting holes 2 on the left and right sides of the machine base 1 to install the positioning side plate 301 in a suitable position through the locking holes on the fixing ears 302. Next, slide the T-shaped slider 304 in the T-shaped slide groove 303 at the top of the positioning side plate 301 to drive the connecting rod 305 to move and adjust the approximate position of the fixing component 4 on the positioning side plate 301. Then, through the locking bolt 307 passing through the threaded hole 308 on the square sleeve 306 and the connecting rod 305, precisely adjust the insertion length of the square sleeve 306 on the connecting rod 305 to complete the fine adjustment of the positioning component 3. Then, according to the shape of the workpiece, rotate the swing rod 402 on the pin 403 inside the fixing plate 401 to a suitable angle, and then rotate the rotating block 406 to make the threaded rod 404 drive the fixing base 405 to move downward. The rubber pad at the bottom of the base tightly adheres to the surface of the workpiece, firmly clamping the workpiece and preventing displacement and shaking during machining, thus achieving accurate positioning and reliable clamping. At this point, the entire process is complete.
