Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and more specifically to a boring machine tooling for the inner bore of a split-type pump body. Background Technology

[0002] A boring machine is a machine tool that primarily uses a boring bar to bore pre-drilled holes in a workpiece. Typically, the rotation of the boring bar is the primary motion, while the movement of the boring bar or workpiece is the feed motion. It is mainly used for machining high-precision holes or for finishing multiple holes in a single positioning operation. It can also perform machining of other surfaces related to hole finishing. Using different tools and accessories, it can also perform drilling, milling, and cutting operations with higher precision and surface finish than drilling machines. Boring machines are the main equipment for machining large box-shaped parts.

[0003] Currently, it is well known that boring, represented by the coaxial hole system of box-type parts, is one of the most important aspects of metal cutting. When a boring machine performs finishing on the pump body of a split-case pump, a lever dial indicator is used to align the pump body. After alignment, the pump body is fixed and clamped before cutting. However, using a lever dial indicator to align the pump body requires a lot of manual intervention, which demands high technical skills from the operator. In addition, the alignment time is long, requiring the operator to slowly rotate the lever dial indicator for alignment, which reduces the efficiency of the boring machine. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a boring machine fixture for the inner bore of a split-type pump body. A limiting rod limits the downward movement of the boring bar to be parallel to the center line of the semi-circular inner bore groove. Then, two sets of adjusting rods move outward synchronously to contact the inner wall of the semi-circular inner bore groove, thereby pushing the pump body to move. This aligns the center of the semi-circular inner bore groove with the center of the bidirectional lead screw, thus placing the boring bar at the center point of the semi-circular inner bore groove. This improves the accuracy and ease of center point alignment during boring and turning.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A boring machine fixture for boring the inner bore of a split-case pump body includes a base, on which a multi-directional sliding support plate and a left-right sliding machining table are mounted. A boring bar is mounted on the top of the support plate, and a limiting rod flush with the center line of the boring bar is mounted on one side of the support plate. A connecting plate is fixedly connected to the top of the support plate, and an adjusting component for adjusting the center point of the pump body and a dust removal component for removing boring chips are mounted at the bottom of the connecting plate.

[0007] As a further embodiment of the present invention: the adjustment assembly includes fixed plates fixedly connected to both sides of the bottom of the connecting plate, a bidirectional lead screw rotatably connected between the two sets of fixed plates, two sets of sliders threadedly connected to the outer wall of the bidirectional lead screw, and an adjustment rod fixedly connected to the bottom of each set of sliders, with the two sets of adjustment rods located on both sides of the boring bar respectively.

[0008] As a further aspect of the present invention: the dust removal assembly includes a fixed frame fixedly connected to the bottom of one end of the connecting plate, a dust suction hood fixedly connected inside the fixed frame, an air suction pump and a collection box fixedly connected to the top of the connecting plate, the air intake end of the air suction pump being connected to the collection box, the collection box being connected to the dust suction hood through a connecting pipe, and a filter plate fixedly connected inside the collection box.

[0009] As a further aspect of the present invention: a magnetic rod is rotatably connected inside the fixing frame, a drive motor is fixedly connected to the top outer wall of the fixing frame, one end of the drive motor passes through the fixing frame and is connected to one end of the magnetic rod, and a scraper is fixedly connected inside the fixing frame, one end of the scraper abutting against the outer wall of the magnetic rod.

[0010] As a further embodiment of the present invention: an adjusting slide rail is fixedly connected to the top of the base, a sliding plate is slidably connected to the top of the adjusting slide rail, a first driving part is provided inside the adjusting slide rail to drive the sliding plate to move, a support frame is fixedly connected to the top of the sliding plate, a lifting screw is rotatably connected inside the support frame, a support plate is threadedly connected to the outer wall of the lifting screw, and both ends of the support plate are respectively attached to the inner walls of both sides of the support frame, an adjusting motor is fixedly connected to the top of the support frame, and the output end of the adjusting motor passes through the support frame and is connected to the lifting screw.

[0011] As a further embodiment of the present invention: a movable slide rail is fixedly connected to the top of the base, the processing table is slidably connected to the top of the movable slide rail, and a second driving part is provided inside the movable slide rail to drive the processing table to move left and right.

[0012] As a further aspect of the present invention: clamping cylinders are fixedly connected to both sides of the bottom of the processing table, and connecting rods are fixedly connected to the output ends of the clamping cylinders, and clamping plates are fixedly connected to the opposite sides of the two sets of connecting rods.

[0013] As a further embodiment of the present invention: a mounting plate is fixedly connected to one side of the support plate, a square rod is fixedly connected to one side of the mounting plate, an adjusting block is slidably connected to the outer wall of the square rod, and a limiting rod is fixedly connected to one side of the adjusting block.

[0014] The beneficial effects of this invention are:

[0015] 1. In this invention, the downward movement of the boring bar is limited by a limiting rod to be parallel to the center line of the semi-circular inner groove. Then, two sets of adjusting rods move outward synchronously to contact the inner wall of the semi-circular inner groove, thereby pushing the pump body to move and aligning the center of the semi-circular inner groove with the center of the bidirectional lead screw. This places the boring bar at the center point of the semi-circular inner groove, improving the accuracy and ease of center point alignment during boring and turning.

[0016] 2. In this invention, a negative pressure suction is generated inside the dust collection hood by the air intake end of the air pump. The iron filings produced by the boring machine are sucked into the dust collection hood by the negative pressure suction, and then enter the collection box. They are intercepted and stored in the collection box by the filter plate. At the same time, the drive motor is started, and the drive motor drives the magnetic rod to rotate. The magnetic rod attracts the iron filings from the boring machine, which further improves the iron filings cleaning effect and avoids iron filings flying. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1-7 As shown, the boring machine fixture for boring the inner bore of a split-type pump body includes a base 1, on which a multi-directional sliding support plate 3 and a left-right sliding machining table 2 are provided. The top of the support plate 3 is provided with a boring bar 301 for boring the pump body. On one side of the support plate 3, a limiting rod 302 flush with the center line of the boring bar 301 is provided for the pump body. A connecting plate 303 is fixedly connected to the top of the support plate 3. The bottom of the connecting plate 303 is provided with an adjusting component 4 for adjusting the center point of the pump body and a dust removal component 5 for removing iron filings from the boring hole.

[0028] Among them, such as Figure 5 and Figure 6As shown, the aforementioned adjustment assembly 4 includes fixed plates 401 fixedly connected to both sides of the bottom of the connecting plate 303. A bidirectional lead screw 402 is rotatably connected between the two sets of fixed plates 401. The aforementioned boring bar 301 is located at the center of the bidirectional lead screw 402. At the same time, a positioning motor 405 is fixedly connected to one side of one set of fixed plates 401. The output end of the positioning motor 405 passes through the fixed plate 401 and is connected to one end of the bidirectional lead screw 402 for driving. The two sets of threaded grooves with opposite directions on the outer wall of the bidirectional lead screw 402 are respectively screwed... The boring bar 301 is connected to two sets of sliders 403, and each set of sliders 403 is fixedly connected to an adjusting rod 404 at its bottom. The two sets of adjusting rods 404 are located on both sides of the boring bar 301. By moving the two sets of adjusting rods 404 outward synchronously and contacting the inner wall of the semi-circular inner hole groove, the pump body is pushed to move, so that the center of the semi-circular inner hole groove is aligned with the center of the double-acting lead screw 402. This makes the boring bar 301 located at the center point of the semi-circular inner hole groove, improving the accuracy and ease of center point alignment of the boring bar 301 during boring and turning.

[0029] Among them, such as Figure 1 , Figure 5 and Figure 7 As shown, in order to facilitate the collection of iron filings generated by the boring machine, the dust removal assembly 5 includes a fixed frame 501 fixedly connected to the bottom of one end of the connecting plate 303. A dust suction hood 502 is fixedly connected inside the fixed frame 501. An air suction pump 503 and a collection box 504 are fixedly connected to the top of the connecting plate 303. The air inlet of the air suction pump 503 is connected to the collection box 504. The collection box 504 is connected to the dust suction hood 502 through a connecting pipe. A filter plate 5041 is fixedly connected inside the collection box 504.

[0030] like Figure 5 and Figure 7 As shown, in order to improve the collection effect of iron filings, a magnetic rod 505 is rotatably connected inside the aforementioned fixing frame 501. The magnetic rod 505 attracts and collects the iron filings. At the same time, a drive motor 506 is fixedly connected to the top outer wall of the fixing frame 501. One end of the drive motor 506 passes through the fixing frame 501 and is connected to one end of the magnetic rod 505. A scraper 507 is fixedly connected inside the fixing frame 501. One end of the scraper 507 abuts against the outer wall of the magnetic rod 505 to scrape off the iron filings attracted to the outer wall of the magnetic rod 505. Then, the iron filings are sucked up and collected by the dust collection hood 502.

[0031] like Figure 1 and Figure 3As shown, in order to facilitate the adjustment of the position of the boring bar 301, an adjusting slide rail 6 is fixedly connected to the top of the base 1. A sliding plate 601 is slidably connected to the top of the adjusting slide rail 6. A first driving part 605 is provided inside the adjusting slide rail 6 to drive the sliding plate 601 to move left and right. At the same time, a support frame 602 is fixedly connected to the top of the sliding plate 601. A lifting screw 603 is rotatably connected inside the support frame 602. A support plate 3 is threadedly connected to the outer wall of the lifting screw 603 to move up and down. The two ends of the support plate 3 are respectively attached to the inner walls of the two sides of the support frame 602 to limit the position of the support plate 3. An adjusting motor 604 is fixedly connected to the top of the support frame 602. The output end of the adjusting motor 604 passes through the support frame 602 and is connected to the lifting screw 603.

[0032] like Figure 2 and Figure 4 As shown, in order to facilitate the adjustment of the initial position of the pump body, a movable slide rail 201 is fixedly connected to the top of the base 1. The processing table 2 slides on the top of the movable slide rail 201. At the same time, a second drive unit 202 is provided inside the movable slide rail 201 to drive the processing table 2 to move left and right to adjust the position.

[0033] like Figure 2 and Figure 4 As shown, in order to facilitate the clamping and fixing of the pump body, clamping cylinders 203 are fixedly connected to both sides of the bottom of the above-mentioned machining table 2. Connecting rods 204 are fixedly connected to the output end of the clamping cylinders 203. Clamping plates 205 are fixedly connected to the opposite side of the two sets of connecting rods 204. By activating the two sets of clamping cylinders 203, the clamping plates 205 on the two sets of connecting rods 204 are moved to clamp and fix the pump body on both sides of the machining table 2, so as to prevent the pump body from moving during boring.

[0034] like Figure 2 , Figure 3 and Figure 6 As shown, in order to facilitate the adjustment of the position of the limiting rod 302, a mounting plate 3021 is fixedly connected to one side of the support plate 3, and a square rod 3022 is fixedly connected to one side of the mounting plate 3021. An adjusting block 3023 is slidably connected to the outer wall of the square rod 3022. The limiting rod 302 is fixedly connected to one side of the adjusting block 3023. By sliding the adjusting block 3023 on the square rod 3022, the limiting rod 302 is moved, thereby adjusting the position of the limiting rod 302 at the top of the pump body at the distance from the side of the semi-circular inner hole groove. This makes it easier for the boring bar 301 to be positioned parallel to the center line of the semi-circular inner hole grooves of different diameters.

[0035] The first drive unit 605 and the second drive unit 202 in this application are driven by a motor lead screw moving block.

[0036] The working principle of this invention is as follows: When using the pump, the user places the pump body on the machining table 2, and then the second drive unit 202 moves the machining table 2 to adjust the position of the pump body so that the semi-circular inner hole groove to be bored on the pump body is directly below the boring bar 301. Then, the adjustment motor 604 is started, which drives the lifting screw 603 to rotate. The support plate 3, which is threaded to the outer wall of the lifting screw 603, drives the boring bar 301 and the limiting rod 302 to move downward. When the limiting rod 302 is in contact with the top of the side wall of the inner hole groove, the adjustment motor is stopped. Machine 604, at this time, the boring bar 301 is parallel to the center line of the semi-circular inner groove. Then, the positioning motor 405 is started, which drives the double-acting lead screw 402 to rotate. The two sets of threaded grooves with opposite directions on the double-acting lead screw 402 drive the two sets of sliders 403 to move outward synchronously. The two sets of sliders 403 drive the two sets of adjusting rods 404 to move to both sides. When one set of adjusting rods 404 abuts against the inner wall of the semi-circular inner groove, the other set of adjusting rods 404 pushes the pump body to move and adjust the position of the pump body, so that the center point of the semi-circular inner groove on the pump body is aligned with the boring bar 301. The position of the center is moved. When the two sets of adjusting rods 404 are in contact with the inner walls on both sides of the semi-circular inner groove, the center point of the adjusted semi-circular inner groove coincides with the center line of the boring bar 301, thus centering the boring bar 301. The positioning motor 405 is stopped, completing the alignment of the boring bar 301 with the center point of the semi-circular inner groove, improving the accuracy and convenience of alignment. Then, the boring bar 301 drives the boring tool to bore the inner wall of the semi-circular inner groove. At the same time as boring, the suction pump 503 is started. The air intake end of the suction pump 503, through the collection box 504, draws air into the dust collection hood 502. A negative pressure suction is generated, and the iron filings produced by the boring machine are sucked into the dust collection hood 502 and then into the collection box 504. They are intercepted and stored in the collection box 504 by the filter plate 5041. At the same time, the drive motor 506 is started, which drives the magnetic rod 505 to rotate. The magnetic rod 505 adsorbs the iron filings from the boring machine, further improving the iron filings cleaning effect and preventing iron filings from flying. The iron filings adsorbed by the magnetic rod 505 are scraped off by the scraper 507 as it rotates. The scraped iron filings are then sucked up and collected by the dust collection hood 502.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
