[0001] The utility model relates to accessory casting processing technical field, especially in a kind of stable durable band saw machine accessory casting processing positioning device. BACKGROUND

[0002] Band saw machine is often used tool in modern production and processing, and band saw machine needs to rely on various accessories to work cooperatively to realize its sawing function, and accessory casting provides key structural support and functional components for band saw machine, and band saw machine accessory casting processing positioning device is mainly used to ensure the position accuracy and stability of band saw machine accessory casting during processing, so as to ensure processing precision and quality, and in actual application, band saw machine accessory casting processing positioning device usually needs to have the following characteristics:

[0003] 1, high-precision positioning capability, which can meet the requirements of complex shape and high-precision casting processing.

[0004] 2, good stability, which can withstand various forces and vibrations during processing and keep the position of casting unchanged.

[0005] 3, durability, which can withstand high-strength work for a long time without obvious wear or damage.

[0006] At present, in the field of band saw machine accessory casting processing, manufacturers use various positioning devices and methods to realize positioning function.

[0007] For example, a kind of accessory processing positioning tool is disclosed in Chinese patent CN218397824U, which is provided with a servo motor, a sliding block, a clamping panel and a threaded rod, and this design can make a servo motor drive the clamps to move closer to each other.

[0008] However, the above-mentioned method has a prominent problem, i.e., the above-mentioned device clamps the accessory by controlling the sliding of two clamping panels, but since the surface of clamping panel is relatively flat, in order to ensure stable clamping in the expected position, pre-positioning of accessory is needed before clamping work, which increases operation steps and reduces overall work efficiency. UTILITY MODEL CONTENT

[0009] (I) Technical problem solved

[0010] In view of the deficiencies of the prior art, the utility model provides a kind of stable durable band saw machine accessory casting processing positioning device, which solves the technical problem that the above-mentioned device clamps the accessory by controlling the sliding of two clamping panels, but since the surface of clamping panel is relatively flat, in order to ensure stable clamping in the expected position, pre-positioning of accessory is needed before clamping work, which increases operation steps and reduces overall work efficiency.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A stable and durable positioning device for processing castings of band saw accessories includes a processing table. A cylinder is fixedly connected to the upper end of the processing table. A sliding seat is sleeved on the outer surface of the cylinder and slidably connected to the upper end of the processing table. A round rod is sleeved inside the sliding seat. A first positioning seat is slidably connected to the outer surface of the round rod. Two second positioning seats are fixedly connected to the upper end of the processing table. A positioning mechanism is fixedly connected inside the first positioning seat and the two second positioning seats. The positioning mechanism includes three sets of circular clamping blocks, which are respectively sleeved inside the first positioning seat and the two second positioning seats.

[0014] Preferably, the outer surfaces of the three sets of circular clamping blocks are all fitted with rubber sleeves, and a placement plate is fixedly connected to the upper end of the processing table.

[0015] Preferably, an L-shaped connecting plate is fixedly connected to the lower end of the sliding seat.

[0016] Preferably, a limiting block is fixedly connected to the inner surface of the L-shaped connecting plate, and a set of slots is provided inside the limiting block.

[0017] Preferably, a handle rod is slidably connected inside the processing table.

[0018] Preferably, a counterweight is fixedly connected to the outer surface of the handle rod, and a return spring is sleeved on one end of the outer surface of the handle rod near the counterweight.

[0019] (III) Beneficial Effects

[0020] 1. After the part casting is placed stably, the cylinder is activated. The cylinder output shaft approaches one end of the second positioning seat, pushing the sliding seat to slide. The sliding seat causes the circular clamping block connected in the first positioning seat to first come into contact with the surface of the part casting. The first positioning seat pushes the part casting to slide until it reaches a position where it is in contact with a second positioning seat. At this time, the second positioning seat is in contact with the surface of the part casting and limits its movement. The cylinder output shaft then extends, and the first positioning seat is squeezed and slides away from the already contacted second positioning seat until the workpiece is in contact with the circular clamping block connected in the two second positioning seats. This ensures the stable clamping of the workpiece and enables the automatic and precise positioning of the part casting, which helps to improve the flexibility of the device and the efficiency of the positioning operation.

[0021] 2. When the sliding seat slides for clamping and positioning, it drives the L-shaped connecting plate at its bottom to slide. The L-shaped connecting plate then drives the limiting block to slide inside the processing table. After the limiting block is slid, it pushes the handle rod upward through the slot surface. A counterweight is connected to the outer surface of the handle rod. When the next slot inside the limiting block and the surface of the handle rod are in contact, the weight of the handle rod and the counterweight slides downward to reset and lock into the slot. When the sliding seat drives the limiting block to the clamping and positioning position, the vertical surface of the slot and the handle rod are in contact to limit the sliding seat, preventing the sliding seat from slipping due to shaking during processing, and improving the stability and controllability of the sliding seat during positioning and clamping operations.

[0028] This application provides a stable and durable positioning device for processing castings of band saw accessories. It effectively solves the problem of the aforementioned device, which uses two sliding clamping panels to clamp and position accessories. However, because the clamping panel surfaces are relatively flat, pre-positioning of the accessories is required before clamping to ensure stable clamping at the expected position, increasing operational steps and reducing overall work efficiency. After the accessory casting is placed stably, the cylinder is activated. The cylinder output shaft, near the end of the second positioning seat, pushes the sliding seat to slide. The sliding seat causes the circular clamping block connected in the first positioning seat to first come into contact with the surface of the accessory casting. The first positioning seat then pushes the accessory casting to slide until it reaches a position where it contacts a second positioning seat. At this point, the second positioning seat contacts and limits the surface of the accessory casting. The cylinder output shaft then extends, and the first positioning seat, under pressure, slides away from the already contacted second positioning seat until the workpiece contacts the circular clamping block connected in the two second positioning seats, ensuring stable clamping of the workpiece. This allows for automatic and precise positioning of the accessory casting, improving the flexibility of the device and the efficiency of the positioning operation.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that the above-mentioned device clamps and positions the parts by controlling the sliding of two clamping panels. However, since the surface of the clamping panels is relatively flat, in order to ensure stable clamping in the expected position, the parts need to be pre-positioned before clamping, which increases the operation steps and reduces the overall work efficiency. The overall idea is as follows: A stable and durable positioning device for processing castings of band saw parts includes a processing table 11. A cylinder 12 is fixedly connected to the upper end of the processing table 11. A sliding seat 13 is sleeved on the outer surface of the cylinder 12. The sliding seat 13 is slidably connected to the upper end of the processing table 11. A round rod 14 is sleeved inside the sliding seat 13. A first positioning seat 15 is slidably connected to the outer surface of the round rod 14. Two second positioning seats 16 are fixedly connected to the upper end of the processing table 11. A positioning mechanism is fixedly connected inside the first positioning seat 15 and the two second positioning seats 16. The positioning mechanism includes three sets of circular clamping blocks 17. The three sets of circular clamping blocks 17 are respectively sleeved on the first positioning seat 15 and the two second positioning seats 16. Inside the second positioning seat 16, after the part casting is placed stably, the cylinder 12 is activated. The output shaft of the cylinder 12 pushes the sliding seat 13 to slide near the end of the second positioning seat 16. The sliding seat 13 drives the circular clamping block 17 connected in the first positioning seat 15 to first fit against the surface of the part casting, and pushes the part casting to slide through the first positioning seat 15. The part casting is then in a position where it fits against a second positioning seat 16. At this time, the second positioning seat 16 fits against the surface of the part casting and limits its position. The output shaft of the cylinder 12 then extends (when dealing with part castings of different batches and sizes, the extension length of the cylinder 12 output shaft is set in advance to ensure the uniformity of the positioning and clamping position). At this time, the first positioning seat 15 is squeezed and slides away from the second positioning seat 16 until the workpiece fits against the circular clamping block 17 connected in the two second positioning seats 16, ensuring the stable clamping of the workpiece, so as to automatically and accurately position the part casting, which is beneficial to improving the flexibility of the device and the efficiency of the positioning operation.

[0031] The outer surfaces of the three sets of circular clamping blocks 17 are all fitted with rubber sleeves 18. A placement plate 19 is fixedly connected to the upper end of the processing table 11. The placement plate 19 is fixedly connected between the first positioning seat 15 and the two second positioning seats 16. The band saw accessory casting to be processed is placed on the placement plate 19. The surface of the placement plate 19 is a smooth surface that has been polished. When the accessory casting is squeezed and slid on the surface of the placement plate 19, it will not be worn or scratched due to the relatively rough bottom. The accessory casting is positioned by the first positioning seat 15 and the two second positioning seats 16 connected to the upper end of the processing table 11. The circular clamping blocks 17 installed in the first positioning seat 15 and the two second positioning seats 16 clamp and fix the accessory casting, ensuring the stability of the accessory casting. The rubber sleeves 18 fitted on the surfaces of the three sets of circular clamping blocks 17 are in contact with the surface of the accessory casting. At this time, the accessory casting is placed on the smooth plane of the placement plate 19, ensuring the integrity of the surface of the accessory casting while stabilizing the processing, thereby improving the quality of the accessory casting after processing and thus improving the stability and durability of the accessory casting.

[0032] An L-shaped connecting plate 21 is fixedly connected to the lower end of the sliding seat 13. A limit block 22 is fixedly connected to the inner surface of the L-shaped connecting plate 21. A set of slots 23 are opened inside the limit block 22. A handle rod 24 is slidably connected inside the processing table 11. The handle rod 24 and the set of slots 23 are adapted to each other. A counterweight 25 is fixedly connected to the outer surface of the handle rod 24. A return spring 26 is sleeved on the end of the outer surface of the handle rod 24 near the counterweight 25. The return spring 26 is sleeved inside the processing table 11. When the sliding seat 13 slides to perform clamping and positioning work, the sliding seat 13 will drive the L-shaped connecting plate 21 connected to its bottom to slide. The L-shaped connecting plate 21 drives the limit block 22 to slide inside the processing table 11. The slot 23 opened inside the limit block 22 is an inclined through groove similar to a right-angled triangle. When the limit block 22 is driven to slide, it will pass through the slot. The handle rod 24 slides upwards from the surface of the 23. A counterweight 25 is connected to the outer surface of the handle rod 24. When the lower slot 23 in the limiting block 22 is in contact with the surface of the handle rod 24, the weight of the handle rod 24 and the counterweight 25 causes it to slide downwards and reset, locking into the slot 23. When the sliding seat 13 drives the limiting block 22 to slide to the clamping and positioning position, the vertical surface of the slot 23 and the handle rod 24 are in contact to limit the sliding seat 13, preventing the sliding seat 13 from slipping due to shaking during processing. This improves the stability and controllability of the sliding seat 13 during positioning and clamping operations. When the part casting is processed and the cylinder 12 output shaft needs to be reset to pick up the part casting, the handle rod 24 is pulled outwards. At this time, the handle rod 24 extends out of the slot 23 and cancels its limitation. At this time, the cylinder 12 output shaft can be controlled to reset.

[0033] To address the problems existing in the prior art, this utility model provides a stable and durable positioning device for processing castings of band saw accessories. After the casting is placed stably, the cylinder 12 is activated. The output shaft of the cylinder 12 pushes the sliding seat 13 to slide near the end of the second positioning seat 16. The sliding seat 13 drives the circular clamping block 17 connected in the first positioning seat 15 to first fit against the surface of the casting. The first positioning seat 15 pushes the casting to slide until the casting is in contact with a second positioning seat 16. At this time, the second positioning seat 16 fits against the surface of the casting and limits its movement. The output shaft of the cylinder 12 then extends, and the first positioning seat 15 slides away from the already fitted second positioning seat 16 under the pressure until the workpiece fits against the circular clamping block 17 connected in the two second positioning seats 16, ensuring the stable clamping of the workpiece. This allows for automatic and precise positioning of the casting, which improves the flexibility of the device and the efficiency of the positioning operation.

[0034] Working principle:

[0035] The first step involves placing the band saw accessory casting to be processed onto the placement plate 19. The surface of the placement plate 19 is a polished smooth surface, preventing wear and scratches caused by the rough bottom of the casting when it is pressed and slid on the surface of the placement plate 19. The accessory casting is positioned by the first positioning seat 15 and two second positioning seats 16 connected to the upper end of the processing table 11. The circular clamping blocks 17 installed in the first positioning seat 15 and the two second positioning seats 16 clamp and fix the accessory casting, ensuring the stability of the placement. The rubber sleeves 18 fitted onto the surfaces of the three sets of circular clamping blocks 17 are in contact with the surface of the accessory casting. At this time, the accessory casting is placed on the smooth plane of the placement plate 19, ensuring the integrity of the surface of the accessory casting while stabilizing the processing, thereby improving the quality of the accessory casting after processing and improving its stability and durability.

[0036] In the second step, after the part casting is placed stably, cylinder 12 is activated. The output shaft of cylinder 12 pushes the sliding seat 13 to slide near the end of the second positioning seat 16. The sliding seat 13 drives the circular clamping block 17 connected in the first positioning seat 15 to first fit against the surface of the part casting, and pushes the part casting to slide through the first positioning seat 15 until the part casting is in contact with a second positioning seat 16. At this time, the second positioning seat 16 fits against the surface of the part casting and limits its position. Then the output shaft of cylinder 12 extends (when dealing with part castings of different batches and sizes, the extension length of the output shaft of cylinder 12 is set in advance to ensure the uniformity of the positioning and clamping position). At this time, the first positioning seat 15 slides away from the second positioning seat 16 under the pressure until the workpiece fits against the circular clamping block 17 connected in the two second positioning seats 16, ensuring the stable clamping of the workpiece, so as to automatically and accurately position the part casting, which is beneficial to improve the flexibility of the device and the efficiency of the positioning operation. When the sliding seat 13 slides to perform the clamping and positioning work, the sliding seat 13 will drive the bottom connected to it. The L-shaped connecting plate 21 slides, causing the limiting block 22 to slide inside the processing table 11. The slot 23 inside the limiting block 22 is an inclined through slot similar to a right triangle. When the limiting block 22 is slid, it will push the handle rod 24 upward through the surface of the slot 23. A counterweight 25 is connected to the outer surface of the handle rod 24. When the slot 23 inside the limiting block 22 and the surface of the handle rod 24 are in contact, the weight of the handle rod 24 and the counterweight 25 will cause it to slide downward and reset, locking into the slot 23. When the sliding seat 1... When the limiting block 22 slides to the clamping and positioning position, the sliding seat 13 is limited by the contact between the vertical surface of the slot 23 and the handle rod 24, which prevents the sliding seat 13 from slipping due to shaking during the processing and improves the stability and controllability of the sliding seat 13 during the positioning and clamping operation. When the part casting needs to be picked up by resetting the output shaft of the cylinder 12 after the part casting is processed, the handle rod 24 is pulled outward. At this time, the handle rod 24 extends out of the slot 23 and cancels the limitation. At this time, the output shaft of the cylinder 12 can be controlled to reset.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
