Description

Technical Field

[0001] The utility model relates to the technical field of deep hole forming, and particularly relates to a thin-wall discontinuous deep hole forming device. Background Technique

[0002] So-called deep hole machining refers to holes where the ratio of the hole length to the hole diameter is greater than 6. In general deep hole machining, in most cases, the depth-diameter ratio L / d ≥ 100. Among these holes, some require high machining accuracy and surface quality, and some of the machined materials have poor machinability, often becoming a major problem in production.

[0003] Application No. CN202321563937.0, a thin-wall discontinuous deep hole machining device, includes a base. Above the base, a machining motor is installed. At the output end of the machining motor, a fixed fixture is installed. On the right side of the fixed fixture, a slide rail is installed. Above the slide rail, a second moving block is installed. Above the second moving block, a limiting fixture is installed. On the right side of the second moving block, a first moving block is installed. Above the first moving block, a fixed cylinder is installed. Inside the fixed cylinder, a limiting hole is opened. A machining drill bit passes through the limiting hole. On the right side of the first moving block, a moving seat is installed. On the outer surface of the base, a limiting groove is opened; this device limits the machining drill bit through the setting of the fixed cylinder and the limiting hole, avoiding damage or deviation of the machining drill bit during machining due to the machining drill bit being too long and too thin; however, when performing deep hole machining on a workpiece, due to the vibration generated during the use of the motor, it is easy to cause loosening of the clamped and limited workpiece and the phenomenon of ineffective limiting.

[0004] Based on this, a thin-wall discontinuous deep hole forming device is proposed to solve the above-mentioned problems. Content of the Utility Model

If there is a description of first and second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0028] In the description of the present utility model, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0029] Please refer to Figures 1-4, the present utility model provides a technical solution: a thin-wall intermittent deep-hole forming device, including a workbench 1, a limit fixing component 7 arranged on the workbench 1, and a buffer component 10 located below the workbench 1. A processing motor 2 is fixedly installed on the top of the workbench 1, and a processing drill bit 3 is installed on the output shaft of the processing motor 2. It should be noted that the positions of the processing drill bit 3 and the workpiece are set flush.

[0030] A driving motor 4 is fixedly installed on the right side of the workbench 1. A chute is opened inside the workbench 1. A lead screw 5 is rotatably installed on the inner wall of the chute. A connecting block 6 is slidably installed in the chute. The lead screw 5 penetrates through the connecting block 6 and is in threaded connection with the connecting block 6. The output shaft of the driving motor 4 penetrates through the workbench 1 and is fixedly connected to the lead screw 5 through a coupling. Start the processing motor 2, and the processing motor 2 drives the processing drill bit 3 to rotate. Then start the driving motor 4, and the driving motor 4 drives the lead screw 5 to rotate. The rotation of the lead screw 5 drives the connecting block 6 to move horizontally. The horizontal movement of the connecting block 6 causes the limit fixing component 7 and the deep-hole part fixed on the limit fixing component 7 to move horizontally, thereby realizing the deep-hole operation.

[0031] The limit fixing component 7 is provided in two groups and is arranged correspondingly, including a mounting block 71, an upper clamping plate 72, a screw rod 73, a guide rod 74, an adjusting block 75, and a lower clamping plate 76. A groove is opened on the connecting block 6, and a mounting block 71 adapted to it is clamped and installed in the groove. The top of the mounting block 71 is connected by a mounting column to an upper clamping plate 72 adapted to the shape of the workpiece. The screw rod 73 is rotatably installed on the top of the mounting block 71. The guide rod 74 is fixedly installed on the top of the mounting block 71. The adjusting block 75 is in threaded connection with the screw rod 73. The guide rod 74 penetrates through the adjusting block 75 and is in sliding connection with the adjusting block 75. The bottom of the adjusting block 75 is connected by a mounting column to a lower clamping plate 76 adapted to the shape of the workpiece. Before the deep-hole operation, by placing the workpiece to be deep-hole between the upper clamping plate 72 and the lower clamping plate 76, rotating the screw rod 73, the screw rod 73 drives the adjusting block 75 to move longitudinally, and the longitudinal movement of the adjusting block 75 drives the lower clamping plate 76 to move longitudinally, so as to fit and fix with the deep-hole part.

[0032] In addition, it should be noted that when the deep-hole part is relatively long, the fixing position of the limit fixing component 7 is at the front end of the deep-hole part, and the fixing position is adjusted as the deep-hole position changes. This step can improve the fixing effect during deep-hole operation.

[0033] Support legs 8 are arranged on the outer walls on both sides of the workbench 1. Limit blocks 9 are slidably installed inside the two support legs 8. The two limit blocks 9 are fixedly connected to the outer walls on both sides of the workbench 1. With the use of the limit blocks 9, the workbench 1 can be limited, including the stable effect during shock absorption.

[0034] The buffer assembly 10 includes a sliding rod 101, sliding blocks 102, springs 103 and support rods 104. The sliding rod 101 is fixedly installed between two groups of support legs 8. Two groups of sliding blocks 102 are slidably installed on the sliding rod 101. The number of springs 103 is two. One end of each spring 103 is fixedly sleeved on the sliding rod 101, and the other end is fixedly connected to the sliding block 102. Two groups of support rods 104 are hingedly installed on the front side of the workbench 1. The free ends of the two groups of support rods 104 are respectively movably connected to the two groups of sliding blocks 102. When the workbench 1 vibrates, it will shake up and down. When it is pressed down, the angles of the two groups of support rods 104 will change, thereby pushing the two groups of sliding blocks 102. The sliding blocks 102 are stressed to squeeze the springs 103. With the cooperation of the damping device, the vibration can be weakened and slowed down, so as to ensure the fixing effect of the deep-hole parts and ensure the deep-hole operation.

[0035] It should be noted that a damping device is provided on the spring 103, which is not shown in the figure.

[0036] It should be noted that two groups of support rods 104 are also hingedly installed on the rear side of the workbench 1, and the support legs 8, limit blocks 9 and buffer assemblies 10 are correspondingly provided, which are not shown in the figure.

[0037] During use, before performing the deep-hole operation, place the deep-hole part to be processed between the upper clamping plate 72 and the lower clamping plate 76, rotate the screw rod 73, the screw rod 73 drives the adjusting block 75 to move longitudinally, and the longitudinal movement of the adjusting block 75 drives the lower clamping plate 76 to move longitudinally, so as to fit and fix with the deep-hole part. Start the processing motor 2, the processing motor 2 drives the processing drill bit 3 to rotate, and then start the driving motor 4, the driving motor 4 drives the lead screw 5 to rotate, the rotation of the lead screw 5 drives the connecting block 6 to move horizontally, and the horizontal movement of the connecting block 6 makes the limit fixing assembly 7 and the deep-hole part fixed on the limit fixing assembly 7 move horizontally, so as to realize the deep-hole operation;

[0038] In addition, it should be noted that when the deep-hole part is long, the fixing position of the limit fixing assembly 7 is at the front end of the deep-hole part, and the fixing position is adjusted as the position of the deep hole changes. This step can improve the fixing effect during deep-hole drilling;

[0039] During operation, since the above motors work to generate vibration, when the workbench 1 vibrates, it will shake up and down. When it is pressed down, the angles of the two groups of support rods 104 will change, thereby pushing the two groups of sliding blocks 102. The sliding blocks 102 are stressed to squeeze the springs 103. With the cooperation of the damping device, the vibration can be weakened and slowed down, so as to ensure the fixing effect of the deep-hole parts.

[0040] In addition, by snap-fitting the installation block 71, the limit fixing assembly 7 can be replaced, so as to replace the clamping plate adapted to the shape of the deep-hole part to adapt to the use of deep-hole parts with different shapes. That is to say, when processing the deep-hole part, the upper clamping plate 72 and the lower clamping plate 76 can always fix it.
