Description

A drilling positioning fixture for processing machine parts Technical Field

[0001] This utility model relates to the field of drilling positioning equipment technology, and in particular to a drilling positioning fixture for processing mechanical equipment parts. Background Technology

[0002] In the machinery manufacturing industry, the machining precision and quality of spare parts play a decisive role in the performance and reliability of the entire equipment. Drilling, as a common and critical step in the machining of mechanical equipment spare parts, directly affects the assembly accuracy and functional realization of the parts. For example, in some high-precision transmission components, even slight deviations in the drilling position and size can lead to reduced transmission efficiency, increased noise, or even equipment failure. Therefore, drilling positioning fixtures hold an irreplaceable and important position in the machining of mechanical equipment spare parts. They provide stable support and precise positioning for drilling operations, ensuring the smooth progress of the drilling process and the stability of machining quality.

[0003] Currently, existing drilling positioning fixtures on the market have many shortcomings in terms of structural design and ease of use. During installation and disassembly, traditional fixtures often require numerous tools and complex bolt tightening and loosening operations. For example, some fixtures require tightening multiple bolts sequentially when fixing components, and the bolt locations may be concealed with limited operating space. This not only increases the workload of operators but also consumes a significant amount of time. When maintenance, replacement of damaged parts, or adjustment of the fixture's position according to different processing requirements are needed, this cumbersome disassembly and assembly process leads to excessive downtime, severely impacting production efficiency. Taking a small to medium-sized machining enterprise as an example, due to the inconvenience of disassembling and assembling traditional drilling positioning fixtures, the adjustment time for each change of processing task averages several hours, resulting in severe production delays and an inability to meet customer order demands in a timely manner, causing significant economic losses to the enterprise.

[0004] Besides the inconvenience of disassembly and assembly, traditional drilling positioning fixtures also have significant shortcomings in terms of positioning and clamping accuracy. Traditional fixtures typically use simple mechanical structures to clamp parts, making it difficult to guarantee the uniformity and stability of the clamping force. During drilling, due to the rotation of the drill bit and the cutting force, parts are prone to shaking or displacement, leading to inaccurate drilling positions and large hole diameter deviations. For example, in the machining of aerospace parts with extremely high drilling accuracy requirements, traditional drilling positioning fixtures cannot meet the stringent tolerance requirements, resulting in a high rate of defective parts, wasting a large amount of raw materials and increasing production costs. Furthermore, insufficient positioning and clamping accuracy can also affect subsequent assembly processes, reducing the overall quality and performance of the machinery. Therefore, we provide a drilling positioning fixture for machining mechanical equipment parts. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling and positioning fixture for processing mechanical equipment parts, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a drilling positioning fixture for processing mechanical equipment parts, comprising: a mounting frame and a mounting bracket, wherein a servo motor is fixedly mounted on the inner wall of the mounting frame, a fixing block is fixedly mounted on the side of the mounting frame, a U-shaped plate is snapped onto the periphery of the fixing block, a support frame is fixedly connected to the lower surface of the U-shaped plate, and a positioning clamping assembly is connected to the mounting bracket;

[0007] A quick-assembly / disassembly mechanism is connected between the fixing block and the U-shaped plate;

[0008] The quick assembly / disassembly mechanism includes a limiting insertion hole on the inner side wall of the U-shaped plate and a sliding groove on the upper surface of the fixing block. A sliding plate is slidably connected to the inner wall of the sliding groove, and a limiting insertion rod is fixedly connected to the surface of the sliding plate. A reciprocating component is connected between the sliding groove and the sliding plate.

[0009] As a further technical solution of this utility model, the positioning and clamping assembly includes a threaded rod rotatably connected to the inner top wall of the mounting frame via a bearing. One end of the threaded rod is fixedly mounted with a connecting block, and the other end of the threaded rod is fixedly mounted with the output end of the servo motor. A fixing rod is fixedly connected between the inner side walls of the mounting frame. A sliding sleeve block is slidably sleeved around the fixing rod. The upper and lower end surfaces of the sliding sleeve block are rotatably connected to rotating connecting rods via rotating shafts, and the ends of the rotating connecting rods are rotatably connected to the upper and lower end surfaces of the connecting block via rotating shafts. A clamping plate is fixedly mounted on the surface of the sliding sleeve block for clamping and positioning mechanical equipment parts.

[0010] As a further technical solution of this utility model, the reciprocating component includes a strip-shaped groove formed on the inner side wall of the sliding groove, a horizontal fixing rod is fixedly connected between the two end walls of the strip-shaped groove, a spring is sleeved around the horizontal fixing rod, and a movable sleeve block is slidably sleeved around the horizontal fixing rod.

[0011] As a further technical solution of this utility model, the movable sleeve block is slidably connected to the inner wall of the strip groove, and the opposite surfaces of the two movable sleeve blocks are fixedly connected to the two end surfaces of a sliding plate.

[0012] As a further technical solution of this utility model, one end of the limiting rod passes through the end wall of the sliding groove and is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is compatible with the outer diameter of the limiting rod.

[0013] As a further technical solution of this utility model, one end of the spring is fixedly connected to the end wall of the strip groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.

[0014] This utility model provides a drilling positioning fixture for processing mechanical equipment parts, which has the following advantages compared with the prior art:

[0015] 1. This design relates to a drilling and positioning fixture for machining machine parts. By incorporating a quick-release mechanism between a fixed block and a U-shaped plate, the fixture enables rapid assembly and disassembly of the U-shaped plate from the fixed block. During installation, the U-shaped plate is simply snapped onto the periphery of the fixed block. With the assistance of the reciprocating mechanism, a limiting rod automatically inserts into the limiting hole to achieve a secure connection. During disassembly, the limiting rod is pulled out of the limiting hole by operating the reciprocating mechanism, allowing the U-shaped plate to be quickly removed. This design significantly reduces installation and disassembly time. When maintenance, component replacement, or position adjustment of the fixture is required, operators can quickly complete the relevant operations, improving work efficiency and reducing production cost losses caused by prolonged downtime for maintenance.

[0016] 2. This design presents a drilling and positioning fixture for machining mechanical equipment parts. A servo motor drives a threaded rod to rotate, which in turn rotates a connecting block, pushing a rotating connecting rod to move. This ultimately causes a sliding sleeve block to slide on a fixed rod, allowing the clamping plate to move precisely and clamp and position the mechanical equipment parts. This structure enables precise displacement control of the clamping plate, ensuring the parts are in a stable and accurate position during drilling. It effectively avoids drilling errors caused by part movement or positional deviations, significantly improving the quality and precision of drilling, reducing scrap rates, enhancing overall product quality, and bringing better economic benefits and market competitiveness to enterprises.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides a drilling positioning fixture for processing mechanical equipment parts: it includes a mounting frame 1 and a mounting bracket 2. A servo motor 3 is fixedly mounted on the inner wall of the mounting frame 1 by bolts. A fixing block 4 is fixedly mounted on the side of the mounting frame 1 by welding. A U-shaped plate 5 is prepared and snapped onto the periphery of the fixing block 4. A support frame 6 is fixedly connected to the lower surface of the U-shaped plate 5 by welding. A positioning clamping assembly is connected to the mounting bracket 2, and a quick-release mechanism is connected between the fixing block 4 and the U-shaped plate 5. A limiting insertion hole 13 is opened on the inner side wall of the U-shaped plate 5, and a sliding groove 14 is opened on the upper surface of the fixing block 4. A sliding plate 19 is slidably connected to the inner wall of the sliding groove 14. A limiting rod 20 is fixedly connected to the surface of the sliding plate 19 by welding. A reciprocating component is connected between the sliding groove 14 and the sliding plate 19. Finally, the U-shaped plate 5 and the fixing block 4 can be quickly disassembled and assembled through the quick-release mechanism. When the limiting rod 20 is inserted into the limiting insertion hole 13, the U-shaped plate 5 and the fixing block 4 are firmly connected. When the limiting rod 20 is pulled out from the limiting insertion hole 13, the U-shaped plate 5 can be quickly disassembled from the fixing block 4.

[0024] As shown in Figures 1-4, a threaded rod 7 is rotatably connected to the inner top wall of the mounting frame 2 via a bearing. A connecting block 8 is fixedly installed at one end of the threaded rod 7 by welding, and the other end of the threaded rod 7 is fixedly installed to the output end of the servo motor 3 via a coupling. A fixing rod 9 is fixedly connected to the inner side wall of the mounting frame 2 by welding, and a sliding sleeve block 10 is slidably sleeved around the fixing rod 9. Rotating connecting rods 11 are rotatably connected to the upper and lower surfaces of the sliding sleeve block 10 via rotating shafts, and the ends of the rotating connecting rods 11 are rotatably connected to the upper and lower surfaces of the connecting block 8 via rotating shafts. A clamping plate 12 is fixedly installed on the surface of the sliding sleeve block 10 by bolts. When the servo motor 3 starts, it drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 causes the connecting block 8 to rotate, which in turn drives the rotating connecting rod 11 to move. The movement of the rotating connecting rod 11 pushes the sliding sleeve block 10 to slide on the fixing rod 9, and finally moves the clamping plate 12, realizing the clamping and positioning of mechanical equipment parts.

[0025] As shown in Figures 1-4, a strip groove 15 is formed on the inner wall of the sliding groove 14. A horizontal fixing rod 16 is fixedly connected between the two end walls of the strip groove 15 by welding. A spring 17 is sleeved on the periphery of the horizontal fixing rod 16. A movable sleeve block 18 is slidably sleeved on the periphery of the horizontal fixing rod 16. Through this reciprocating component, the sliding plate 19 can reciprocate within the sliding groove 14. When an external force is applied to the sliding plate 19, the movable sleeve block 18 slides on the horizontal fixing rod 16, and the spring 17 is compressed or stretched. When the external force disappears, the elastic force of the spring 17 causes the movable sleeve block 18 to reset, thereby driving the sliding plate 19 to reset.

[0026] As shown in Figures 1-4, the movable sleeve 18 is slidably connected to the inner wall of the strip groove 15, and the opposite surfaces of the two movable sleeves 18 are fixedly connected to the two end surfaces of a sliding plate 19 by welding. When the movable sleeve 18 slides in the strip groove 15, it drives the sliding plate 19 to slide in the sliding groove 14, thereby realizing the reciprocating motion of the sliding plate 19.

[0027] As shown in Figures 1-4, one end of the limiting rod 20 passes through the end wall of the sliding groove 14 and is inserted into the inner wall of the limiting hole 13. The inner diameter of the limiting hole 13 is matched with the outer diameter of the limiting rod 20. When the limiting rod 20 is inserted into the limiting hole 13, the U-shaped plate 5 and the fixing block 4 are firmly connected to prevent the U-shaped plate 5 from shaking or falling off the fixing block 4.

[0028] As shown in Figures 1-4, one end of the spring 17 is fixedly connected to the end wall of the strip groove 15 by welding, and the other end of the spring 17 is fixedly connected to one end surface of the movable sleeve 18 by welding. When the movable sleeve 18 slides in the strip groove 15, the spring 17 is compressed or stretched, generating elastic force. When the external force disappears, the elastic force of the spring 17 causes the movable sleeve 18 to reset, thereby driving the sliding plate 19 and the limit rod 20 to reset, realizing the automatic reset function of the quick disassembly and assembly mechanism.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
