Description

Technical Field

[0001] This invention relates to the field of rear axle drive housing manufacturing technology, specifically to a square aluminum cutting device for rear axle drive housing and its cutting process. Background Technology

[0002] The manufacturing process of the rear axle drive housing includes cutting square aluminum and forming. It can be seen that the square aluminum needs to be cut using cutting equipment before the rear axle drive housing can be formed.

[0003] The principle of existing cutting equipment is as follows: the cutting head is moved by a drive device, such as a linear module slide, to achieve cutting at different locations. This has the following problems: First, the cutting blade is generally fixed by multiple fastening devices. When replacing it, each fastening device must be disassembled individually before a new blade can be installed, making blade replacement inconvenient. Second, the cutting blade will accumulate debris during cutting, which is difficult to collect and results in debris remaining inside the machine housing.

[0004] Based on this, the present invention designs a rear axle drive housing square aluminum cutting device and its cutting process to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rear axle drive housing square aluminum cutting device and its cutting process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] The waste collection assembly includes an air jet pipe, a collection hood, and a collection box. The collection hood is fixedly installed on the lower outer wall of the C-shaped box, and the lower end of the collection hood is inserted into the upper end of the collection box. One end of the air jet pipe is fixedly connected to the collection hood.

[0012] The lower end of the cutting assembly is connected to a translation component for driving the cutting assembly and the waste collection assembly to move back and forth.

[0013] Furthermore, the base is installed at the lower end of the support platform, and the waste collection assembly is installed between the support platform and the base.

[0014] Furthermore, one end of the jet pipe is located on one side of the blade tooth groove, and the upper end of the support platform is provided with a blade movable groove to facilitate the back-and-forth movement of the blade.

[0015] Furthermore, the material collection hood is located on one side of the straight groove at the lower end of the C-shaped box.

[0016] Furthermore, the tensioning structure includes a cylinder, a second wedge block, and a first wedge block; the cylinder is fixedly connected to a mounting plate, the mounting plate is fixedly connected to the inner wall of the C-shaped housing, the output end of the cylinder is connected to the first wedge block, the inclined surface at the lower end of the first wedge block is in contact with the inclined surface at the upper end of the second wedge block, two sets of connecting frames are installed at the end of the second wedge block near the driven roller, one set of connecting frames is fixedly connected to the second wedge block, and two sets of upper and lower rotating shafts are rotatably connected between the two sets of connecting frames, and the two driven rollers are respectively fixedly installed on the upper and lower sets of rotating shafts.

The second wedge block is fixedly connected to a second slider at one end near the inner wall of the C-shaped box, and the second slider is slidably connected to a horizontally arranged second guide rail.

[0018] Furthermore, the middle part of the jet pipe is fixedly mounted on the cable chain, the cable chain is mounted on the cable tray, and the lower end of the cable tray is fixedly connected to the base.

[0019] Furthermore, the cables for the drive motor and cylinder are also installed inside the cable chain, and the movable end of the cable chain is fixedly connected to the C-shaped housing.

[0020] Furthermore, the translation component includes a linear module slide, several sets of third guide rails, and several sets of third sliders; the linear module slide and the third guide rails are both fixedly installed on the upper end of the base, and several sets of third sliders are fixedly connected to the lower end of the C-shaped box. The third sliders are slidably connected to each set of third guide rails, and the side of the C-shaped box is fixedly connected to the slider of the linear module slide; the linear module slide and the third guide rails are both arranged in the front-back direction.

[0021] This invention also provides a cutting process for a rear axle drive housing square aluminum cutting device, which includes the following steps:

[0022] Step 1: Activate the cylinder. The cylinder drives the first wedge block to move vertically downward along the first guide rail. The first wedge block drives the second wedge block to move horizontally along the second guide rail. The second wedge block drives the two driven rollers on the connecting frame to move closer to the drive roller. The driven rollers further press the blade belt, thereby achieving the purpose of tensioning the blade belt.

[0023] Step 2: Turn on the drive motor. The drive motor drives the drive roller to rotate, and the drive roller drives the blade belt to rotate.

[0024] Step 3: When replacing the blade belt, remove the C-shaped cover plate from the C-shaped housing. The C-shaped cover plate will drive the second connecting rod and the second guide plate to be removed together for material feeding. At this time, the second guide plate will be separated from the middle column, making it easier to remove the blade belt from the middle column. Then, place the new blade belt on the middle column, and then insert the second guide plates of each part into the middle column. At the same time, connect the C-shaped cover plate to the C-shaped housing.

[0025] Step 4: Activate the linear module slide. The linear module slide drives the C-shaped housing to move back and forth along the third guide rail. The C-shaped housing drives the cutter belt to cut the square aluminum of the rear axle drive housing.

[0026] Step 5: Turn on the air jet pipe. The debris attached to the blade belt is blown off by the air jet pipe into the tooth grooves of the blade belt. The debris falls into the collection hood below under the action of gravity and is then collected by the collection box. Beneficial effects

[0027] This invention uses a drive motor to drive a drive roller to rotate, which in turn drives the blade belt to rotate. A driven roller, in cooperation with the drive roller, guides the movement of the blade belt. A tensioning structure changes the position of the driven roller, thereby tensioning the blade belt. When the blade belt needs to be replaced, the C-shaped cover plate is removed from the C-shaped housing. The C-shaped cover plate, along with the second connecting rod and the second guide plate, is removed and unloaded. At this time, the second guide plate is disengaged from the intermediate column, making it easy to remove the blade belt from the intermediate column. Then, the new blade belt is placed on the intermediate column, and the second guide plates at each part are inserted into the intermediate column. At the same time, the C-shaped cover plate is connected to the C-shaped housing, thus realizing the quick disassembly and replacement of the blade belt.

[0028] This invention uses a blade belt to cut the square aluminum of the rear axle drive housing. After cutting, the blade belt moves through the blade belt's movable groove into the lower end of the support platform. Debris adhering to the blade belt is blown off by air through an air jet pipe into the blade belt's tooth grooves, simultaneously cooling the blade belt. The debris falls into the collection hood below under gravity and is then collected by a collection box. After a period of time, the collection box can be disassembled, cleaned, and then reinstalled at the lower end of the collection hood. This invention solves the problem of debris being difficult to collect, resulting in debris residue inside the chassis. Attached Figure Description

[0046] Straight grooves 43 are provided at the two opposite ends of the C-shaped box 41 to allow the tool belt 42 to pass through.

[0047] The drive motor 45 is fixedly installed on one side of the outer wall of the C-shaped box 41. The output end of the drive motor 45 is fixedly connected to the drive roller 411. The drive roller 411 is located inside the C-shaped box 41. The drive roller 411 is in close contact with one side of the blade belt 42. The other side of the blade belt 42 is in close contact with two driven rollers 412. The driven rollers 412 are connected to the tensioning structure.

[0048] The drive roller 411 is driven to rotate by the drive motor 45, which in turn drives the blade belt 42 to rotate. The driven roller 412, in cooperation with the drive roller 411, guides the movement of the blade belt 42. The tensioning structure changes the position of the driven roller 412, thereby tensioning the blade belt 42. When the blade belt 42 needs to be replaced, the C-shaped cover plate 44 is removed from the C-shaped housing 41. The C-shaped cover plate 44 drives the second connecting rod 49 and the second guide plate 48 to be removed and unloaded together. At this time, the second guide plate 48 is disengaged from the intermediate column 414, making it easy to remove the blade belt 42 from the intermediate column 414. Then, the new blade belt 42 is placed on the intermediate column 414, and the second guide plates 48 at each part are inserted into the intermediate column 414.

The debris attached to the blade belt 42 is blown off by the air jet pipe 31 through the tooth groove of the blade belt 42. At the same time, the blade belt 42 is cooled down. The debris falls into the collection hood 32 below under the action of gravity, and is then collected by the collection box 34. After a period of time, the collection box 34 can be disassembled and cleaned, and then reinstalled at the lower end of the collection hood 32. This invention can solve the problem of debris being difficult to collect and causing debris to remain in the machine housing.

At this time, the second guide plate 48 will be separated from the intermediate column 414, making it easier to remove the blade belt 42 from the intermediate column 414. Then, place the new blade belt 42 on the intermediate column 414, and then insert the second guide plates 48 of each part into the intermediate column 414. At the same time, connect the C-shaped cover plate 44 to the C-shaped housing 41.

[0064] Step 4: Turn on the linear module slide 51. The linear module slide 51 drives the C-shaped housing 41 to move back and forth along the third guide rail 52. The C-shaped housing 41 drives the blade belt 42 to cut the square aluminum of the rear axle drive housing.

[0065] Step 5: Turn on the jet pipe 31. The debris attached to the blade belt 42 is blown off by the jet pipe 31 into the tooth groove of the blade belt 42. The debris falls into the collection hood 32 below under the action of gravity and is then collected by the collection box 34.

[0066] This invention enables the tensioning, quick disassembly and replacement of the blade belt 42, as well as the cleaning and collection of debris attached to the blade belt 42, and the cooling treatment of the blade belt 42.
