Description

Technical Field

[0001] This utility model relates to the field of metal guide rail processing technology, specifically a cutting device for guide rail processing. Background Technology

[0002] Metal guide rail cutting devices are specialized equipment used for high-precision cutting of metal guide rails. They typically use mechanical cutting tools to cut the guide rails, and can efficiently complete straight or irregular cutting, ensuring that the guide rail cross-section is flat and the dimensions are accurate, meeting the stringent requirements of machine tools, automated equipment and other fields for the quality and geometric accuracy of the guide rail guide surface.

[0003] A cutting device for guide rail processing disclosed in Chinese Patent Publication No. CN220921134U uses a rotary motor to drive a rotating rod, which in turn drives a conveyor belt to automatically move the guide rail for easy cutting. The position of the support plate on the slide rail and the rotation of the rotating rod are controlled by holding a support rod, allowing for convenient control of the cutting position and improving work efficiency. The device cuts the guide rail using a cutting structure. However, the overall applicability of the cutting device is low. In metal guide rail cutting, it can only cut multiple sets of guide rails of a single specification. It cannot efficiently and stably cut guide rails of different shapes and specifications, resulting in limitations in its use and affecting overall cutting efficiency. Utility Model Content

The movable seat is L-shaped, and a pair of electric push rods are fixedly connected to the inner wall of the vertical plate of the movable seat. A support is fixedly connected to the head of the two electric push rods. A limit frame is detachably connected to the support, and square slots are evenly opened at the bottom of the limit frame along its length. A cutting mechanism is provided at the center of the upper surface of the worktable, and a fixing frame is fixedly connected to the middle of the upper surface of the worktable. A dust removal mechanism is provided on the lower surface of the fixing frame corresponding to the position of the cutting mechanism. The device also includes a limit mechanism for installing the limit frame on the top of the support.

[0006] Preferably, the limiting bracket is provided in multiple pairs, with two in each pair and the bottom insertion hole size of each pair of limiting brackets is different.

[0007] Preferably, the limiting mechanism includes a first magnetic block slidably connected to the rear side of the support platform, a movable block that slides within the support platform fixedly connected to one side of the first magnetic block, a first spring fixedly connected to one side of the movable block, a push rod slidably connected to the rear end of the support platform, a sliding block that slides within the support platform fixedly connected to the front end of the push rod, a second magnetic block fixedly connected to the center of the front end of the sliding block, the contact surfaces of the first magnetic block and the second magnetic block repel each other magnetically, a second spring fixedly connected to the front end of the sliding block, first inserts that engage with the support platform being fixedly connected at equal intervals on the lower surface of the limiting frame, and a second insert being fixedly connected to the side of the lower surface of the limiting frame away from the first insert, the second insert having a slot for engaging with the first magnetic block inside.

[0008] Preferably, a guide groove is provided at the rear end of the upper surface of the worktable, and a fixing strip is fixedly connected to the rear side of the upper surface of the worktable.

[0009] Preferably, the dust removal mechanism includes four hollow cylinders fixedly connected to the center of the lower surface of the fixed frame, connecting rods slidably connected to the interior of the lower surface of the four hollow cylinders, a movable disc that slides inside the hollow cylinders fixedly connected to the upper surface of the connecting rods, a third spring fixedly connected to the top of the movable discs, and a dust cover fixedly connected to the lower surface of the four connecting rods.

[0010] Preferably, a pressure sensor is fixedly connected to the bottom right side of the hollow cylinder at the left front end, a pressing block corresponding to the position of the pressure sensor is fixedly connected to the top right side of the connecting rod at the left front end, a vacuum cleaner is fixedly connected to the middle position of the top of the dust cover, and a transmission chamber with its top end communicating with the vacuum cleaner is fixedly connected to the center position of the lower surface of the dust cover.

[0011] Preferably, the cutting mechanism includes a cutting groove located at the center of the upper surface of the worktable, a motor is fixedly connected to one side inside the cutting groove, and a cutting blade that rotates inside the cutting groove is installed on the output shaft end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of guide rail processing cutting device, by installing a limit frame on the top of the support table, inserts the first and second insert blocks on the limit frame into the interior of the support table, and simultaneously inserts the first magnetic block inside the support table into the slot on the second insert block, thus completing the installation of the limit frame on the top of the support table. At this time, the two sets of limit frames can perform clamping and limiting work on the metal guide rail. When the limit frame needs to be replaced according to different metal guide rails, the support table is moved by a linear motor. At this time, the fixing bar at the top of the worktable contacts the top rod on the support table, which can push the top rod to move. At this time, the top rod can drive the second magnetic block to move through the sliding block. The second magnetic block approaches the first magnetic block and generates a repulsive magnetic force, which can pull the first magnetic block out of the slot on the second insert block and into the interior of the support table. At this time, the limit frame can be quickly removed from the top of the support table for replacement, thereby performing limiting work on metal guide rails of different specifications.

[0014] 2. This type of guide rail processing cutting device has a dust cover at the bottom of the pressing mechanism. When the linear motor drives the guide rail to be cut to move through the support platform, the guide rail contacts the dust cover and pushes the dust cover upward. At this time, the dust cover can squeeze the third spring through the connecting rod and the movable plate. Due to the reaction force of the squeezed third spring, the dust cover can be pushed to fit against the top of the guide rail and the cutting point through the movable plate and the connecting rod. At the same time, the connecting rod can press the pressure sensor during the lifting process. When the pressure sensor receives pressure exceeding the threshold, it can transmit an electrical signal to the microcontroller and control the vacuum cleaner to start. At the same time, the debris generated by cutting is quickly collected and processed, which improves the overall functionality of the cutting device while ensuring the working environment around the cutting device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides two technical solutions:

[0022] Example 1: A cutting device for guide rail processing includes a worktable 1. The worktable 1 has symmetrically arranged mounting grooves 2 on its upper surface. A linear motor 201 is installed inside the mounting grooves 2. The top of the linear motor 201 drives a movable seat 202. The movable seat 202 is L-shaped. A pair of electric push rods 203 are fixedly connected to the inner wall of the vertical plate of the movable seat 202. A support platform 3 is fixedly connected to the heads of the two electric push rods 203. A limit frame 5 is detachably connected to the support platform 3. Square slots are evenly arranged along the length of the bottom of the limit frame 5. A cutting mechanism 9 is provided at the center of the upper surface. A fixed frame 6 is fixedly connected to the middle of the upper surface of the worktable 1. A dust removal mechanism 7 is provided on the lower surface of the fixed frame 6 corresponding to the position of the cutting mechanism 9. It also includes a limiting mechanism 4. The limiting mechanism 4 is used to install the limiting frame 5 on the top of the support 3. When the linear motor 201 is started, it can drive the moving seat 202 to move on the top of the worktable 1. At the same time, when the electric push rod 203 on the moving seat 202 is started, it can push the limiting frame 5 on the support 3 to move, and make the two limiting frames 5 at the top of the worktable 1 perform multiple sets of guide rail material clamping and limiting work.

[0023] The limit bracket 5 is provided in multiple pairs, with two in each pair and different sizes of the bottom insertion holes of each pair of limit brackets. By installing limit brackets 5 of different specifications on the top of the support platform 3, the clamping work of guide rails of different shapes and specifications can be carried out.

[0024] The limiting mechanism 4 includes a first magnetic block 301 slidably connected to the rear side of the support platform 3. A movable block 302 that slides within the support platform 3 is fixedly connected to one side of the first magnetic block 301. A first spring 303 is fixedly connected to one side of the movable block 302. A push rod 401 is slidably connected to the rear end of the support platform 3. A sliding block 402 that slides within the support platform 3 is fixedly connected to the front end of the push rod 401. A second magnetic block 403 is fixedly connected to the center of the front end of the sliding block 402. The contact surfaces of the first magnetic block 301 and the second magnetic block 403 repel each other magnetically. A second spring 404 is fixedly connected to the front end of the sliding block 402. First inserts 501 that engage with the support platform 3 are evenly and uniformly fixedly connected to the lower surface of the limiting frame 5. A second insert 502 is fixedly connected to the side of the lower surface of the limiting frame 5 away from the first insert 501. The second insert 502 has a slot 5 inside that engages with the first magnetic block 301. 03. When the first magnetic block 301 receives a downward force, it can squeeze the first spring 303 through the movable block 302. At this time, the first magnetic block 301 can be retracted into the support platform 3. When the first magnetic block 301 is no longer subjected to force, and due to the reaction force of the first spring 303 being squeezed, the first magnetic block 301 can be pushed to quickly reset through the movable block 302. By pushing the push rod 401 to move inside the support platform 3, the push rod 401 can push the second magnetic block 403 to move through the sliding block 402. At the same time, the sliding block 402 can squeeze the second spring 404 on one side. Due to the reaction force of the second spring 404 being squeezed, the push rod 401 can be pushed to quickly reset when it is no longer subjected to force. When the second magnetic block 403 on the sliding block 402 approaches the first magnetic block 301, the repulsive force generated by the second magnetic block 403 can push the first magnetic block 301 to move.

[0025] A guide groove 101 is provided at the rear end of the upper surface of the workbench 1, and a fixing strip 102 is fixedly connected to the rear side of the upper surface of the workbench 1. The guide groove 101 can facilitate the guide rail material to be guided and discharged after cutting.

[0026] The cutting mechanism 9 includes a cutting groove 103 located at the center of the upper surface of the worktable 1. A motor 104 is fixedly connected to one side inside the cutting groove 103. A cutting blade 901 that rotates inside the cutting groove 103 is installed on the output shaft end of the motor 104. When the motor 104 is started, it can drive the cutting blade 901 to rotate. At this time, the cutting blade 901 can cut the guide rail material it contacts.

[0027] Example 2 differs from Example 1 mainly in that:

[0028] A cutting device for guide rail processing includes a dust removal mechanism 7 comprising a fixed frame 6 with four hollow cylinders 701 fixedly connected to the center of the lower surface. Connecting rods 702 are slidably connected to the interior of the lower surfaces of the four hollow cylinders 701. A movable disc 703, sliding within the hollow cylinders 701, is fixedly connected to the upper surface of the connecting rods 702. A third spring 704 is fixedly connected to the top of the movable disc 703. A dust cover 8 is fixedly connected to the lower surface of the four connecting rods 702. A pressure sensor 706 is fixedly connected to the bottom right side of the left front hollow cylinder 701. A pressing block 705, corresponding to the position of the pressure sensor 706, is fixedly connected to the top right side of the left front connecting rod 702. A vacuum cleaner 801 is fixedly connected to the middle of the top of the dust cover 8. A transmission chamber 802, communicating with the vacuum cleaner 801, is fixedly connected to the center of the lower surface of the dust cover 8. When the dust cover 8 contacts the guide rail and is lifted, it can be lifted by connecting the connecting rods 702 and the movable disc 701. 03. The third spring 704 is squeezed, and due to the reaction force of the squeezed third spring 704, the dust cover 8 can be pushed close to the top of the guide rail material through the movable plate 703 and the connecting rod 702. At the same time, when the dust cover 8 is raised, the pressing block 705 on the connecting rod 702 can press the pressure sensor 706 on the hollow cylinder 701. At this time, the pressure sensor 706 senses the pressure signal and converts it into an electrical signal, which is then used by the microcontroller to control the vacuum cleaner 801 to start dust removal. The pressure sensor 706 receiving the pressure signal and controlling the vacuum cleaner 801 to start is a conventional technical field in the prior art. The specific installation method, circuit connection method and control method of the pressure sensor 706 and the vacuum cleaner 801 are all conventional designs and will not be described in detail in this work. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] In this embodiment, the guide rail material to be cut is placed in the middle of the two sets of limiting frames 5 at the top of the workbench 1. At this time, the electric push rod 203 on one side of the movable seat 202 is activated, and the limiting frame 5 can be moved by the support 3. At this time, the two sets of limiting frames 5 can clamp the metal guide rail material. At this time, the linear motor 201 is activated, which can push the two sets of limiting frames 5 to move, and the limiting frames 5 can move the guide rail material. When the guide rail material comes into contact with the dust cover 8, the dust cover 8 can move upward. At this time, the dust cover 8 pushes the movable plate 703 upward through the connecting rod 702, which can squeeze the third spring 704 above. Due to the reaction force of the third spring 704 being squeezed, the movable plate 703 and the connecting rod 702 are close to the top of the guide rail material. At this time, as the limiting frame 5 moves the guide rail material, the motor 104 is activated to drive the cutting blade 901 to rotate, and the cutting blade 901 can quickly cut the guide rail material.
