Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a horizontal boring machine for automotive parts processing. Background Technology

[0002] A boring machine is a machine tool that mainly uses a boring bar to bore pre-drilled holes in a workpiece. Typically, the rotation of the boring bar is the main motion, and 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 one positioning. In addition, it can also perform machining of other surfaces related to hole finishing. With different tools and accessories, it can also perform drilling, milling, and cutting. The machining accuracy and surface quality are higher than those of drilling machines. Boring machines are the main equipment for machining large box-shaped parts, such as threads, outer diameters, and end faces.

[0003] However, in the existing technology, the machining of automotive parts by existing horizontal boring machines is accomplished by cutting tools on the spindle box. Therefore, before operation, the automotive parts to be machined need to be placed on the worktable. There are many types of automotive parts, some of which are large in size and weight. When placing such parts on the worktable, the state of the worktable is not easy to change, which is very inconvenient in actual operation. It is easy for the parts to collide with the boring machine, resulting in wear and tear on the parts. In addition, when the horizontal boring machine is machining, various debris is scattered all over the worktable, which is inconvenient for subsequent cleaning. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. When installing some large or bulky parts, it is only necessary to fix one side of the part to the lowest side of the main body of the workbench, and then return the entire workbench to a horizontal state. In addition, the tiltable design allows the residue on the surface of the workbench to slide off to the side, thereby speeding up the subsequent cleaning process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal boring machine for processing automotive parts, comprising a spindle box, a boring machine body, and a worktable. The spindle box is fixedly installed at one end of the boring machine body, and the worktable is movably installed on the upper surface of the boring machine body. The spindle box is located on one side of the worktable. The worktable includes a support device, a locking device support platform, a partition shell, and a worktable body. The locking device is fixedly installed on both sides of the support device, the support platform is movably installed on the top of the support device, the worktable body is fixedly installed on the top of the support platform, and the partition shell is fixedly installed at the junction of the worktable body and the support platform.

[0006] In a preferred embodiment, the support device includes a drive motor, a reversing device, a synchronous support ring, a limiting slide, a widening panel, and a reinforcing support column. The drive rod of the drive motor is movably connected inside the reversing device. The synchronous support ring is installed on both sides of the reversing device. The limiting slide is fixedly installed inside the synchronous support ring. The widening panel is movably installed at both ends of the reversing device. Both ends of the reinforcing support column are fixedly connected to the outer wall of the widening panel.

[0007] The beneficial effects of adopting the above-mentioned further solution are: by reducing the cross-sectional area of ​​the bottom of the workbench body through the support platform, the workbench body angle can be changed, and its maximum rotation range and angle can be limited to avoid affecting the normal balance of the workbench. The support device uses a synchronous support ring to synchronously determine the state of both ends of the workbench, thus avoiding inconsistent rotation amplitude at both ends when adjusting the direction.

[0008] In a preferred embodiment, the reversing device includes a reversing turntable, a central reversing shaft, closed ports, a fixing buckle, and a positioning ring. The closed ports are fixedly installed at both ends of the central reversing shaft, the reversing turntable is fixedly installed on one side of one of the closed ports, one end of the fixing buckle is movably connected to the inside of the positioning ring, and the other end of the fixing buckle is movably connected to one side of the other closed port.

[0009] The advantages of adopting the above-mentioned further solution are: the reversing turntable is connected to the drive motor, and the angle is adjusted by rotating the central reversing shaft. The positioning ring is used to cooperate with the reversing turntable at the other end to determine the position of the central reversing shaft. The connection tightness between the ring and the central reversing shaft is improved by fixing buckles and sealing ports.

[0010] In a preferred embodiment, triangular support plates are movably mounted at both the upper and lower ends of the central reversing shaft. An anti-slip groove is provided at the junction of the central reversing shaft and the triangular support plate. A through hole is provided at the center of the central reversing shaft. A connecting rod is provided inside the through hole. The connecting rod passes through the central reversing shaft and the triangular support plate. A limit ring is threadedly connected at the junction of the connecting rod and the triangular support plate.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the triangular support plate helps to reduce the overall mass of the entire steering device without affecting the support effect, and helps to reduce the load on the drive motor.

[0012] In a preferred embodiment, one end of the widened panel is fixedly connected to one side of the triangular support plate, the deflector is fixed in the shape of a rod inside the synchronous support ring, and the deflector is located at the center point of the synchronous support ring.

[0013] The advantages of adopting the above-mentioned further solution are: determining the center of rotation to avoid instability of the center of gravity, and at the same time using the widened panel to increase the support area of ​​the triangular support plate to ensure the overall structural strength.

[0014] In a preferred embodiment, the locking device includes a limiting frame, an extension support plate, a support base, and an electric telescopic column. The extension support plate is fixedly installed on both sides of the limiting frame, the support base is fixedly installed on one end of the extension support plate, and one end of the electric telescopic column is movably installed on the top of the support base.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the locking device can lock the horizontal state of the device while determining the horizontal line of the device, so as to prevent the worktable from swaying left and right during normal processing.

[0016] In a preferred embodiment, a limiting shell is fixedly installed on both sides of the limiting frame, a lock is movably installed at the other end of the electric telescopic column, and an arc-shaped groove is provided on the inner wall of the limiting frame.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the bolt lock is controlled by an electric telescopic column, and the movement direction of the bolt lock is limited a second time by the limiting shell, so as to lock the horizontal state of the device.

[0018] In a preferred embodiment, the arc-shaped groove is slidably connected to one end of the limiting slide, and the other end of the locking pin is engaged with the outer wall of the reinforcing support column.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the arc groove can be used in conjunction with the limiting slide to determine the direction change route of the direction change device, and the insertion of the lock into the gap between the reinforcing support column can lock the horizontal state of the device.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0021] 1. In this invention, the cross-sectional area of ​​the bottom of the workbench body is reduced by using a support platform, thereby providing room for changing the angle of the workbench body and limiting its maximum rotation range and angle to avoid affecting the normal balance of the workbench. The support device uses a synchronous support ring to synchronously determine the state of both ends of the workbench, avoiding inconsistent rotation amplitudes at both ends when adjusting the direction. Both sides are reinforced with support columns and widened panels to obtain a more stable support effect, while also determining the horizontal line of the device.

[0022] 2. In this invention, the angle adjustment of the reversing device is mainly achieved by the central reversing shaft. The triangular support plate helps to reduce the overall weight of the reversing device and does not affect the support effect. It also reduces the difficulty of changing the angle of the entire workbench. When installing some accessories with large weight or volume, it is only necessary to fix one side of the accessory to the lowest side of the main body of the workbench, and then return the entire workbench to a horizontal state. In addition, the tiltable design allows the residue on the surface of the workbench to slide to one side, thereby speeding up the subsequent cleaning. Attached Figure Description

[0036] 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.

[0037] Example 1

[0038] like Figure 1-2 As shown, the present invention provides a technical solution: a horizontal boring machine for processing automotive parts, including a spindle box 1, a boring machine body 2, and a worktable 3. The spindle box 1 is fixedly installed at one end of the boring machine body 2, and the worktable 3 is movably installed on the upper surface of the boring machine body 2. The spindle box 1 is located on one side of the worktable 3. The worktable 3 includes a support device 31, a locking device 32, a support platform 33, a partition shell 34, and a worktable body 35. The locking device 32 is fixedly installed on both sides of the support device 31, the support platform 33 is movably installed on the top of the support device 31, the worktable body 35 is fixedly installed on the top of the support platform 33, and the partition shell 34 is fixedly installed at the junction of the worktable body 35 and the support platform 33.

[0039] In this embodiment, the spindle box 1 controls the operation of the cutting tool, while the worktable 3 can move on the boring machine body 2 to approach or move away from the spindle box 1. The support platform 33 at the bottom of the worktable 3 has a smaller cross-sectional area than the worktable body 35, thereby providing room for changing the angle of the worktable body 35. With the larger edge size of the partition shell 34, the maximum rotation range and angle of the worktable body 35 can be limited. The support device 31 is mainly used to change the angle of the worktable body 35, and the locking devices 32 on both sides can lock the horizontal state of the support device 31 to avoid affecting the normal balance of the worktable 3 and prevent the worktable 3 from shaking during normal processing.

[0040] Example 2

[0041] like Figure 3-4As shown, the support device 31 includes a drive motor 311, a reversing device 312, a synchronous support ring 313, a limiting slide 314, a widened panel 315, and a reinforcing support column 316. The drive rod of the drive motor 311 is movably connected inside the reversing device 312. The synchronous support ring 313 is installed on both sides of the reversing device 312. The limiting slide 314 is fixedly installed inside the synchronous support ring 313. The widened panel 315 is movably installed at both ends of the reversing device 312. Both ends of the reinforcing support column 316 are fixedly connected to the outer wall of the widened panel 315.

[0042] In this embodiment, the support device 31 is directly driven by the drive motor 311 to operate the reversing device 312. During the reversing process, the synchronous support rings 313 on both sides can synchronously determine the state of both ends of the worktable 3, avoiding the situation where the rotation amplitude of both ends is inconsistent when adjusting the direction. The limiting slide 314 can perform secondary limiting on the rotation path to prevent misalignment. At the same time, both sides of the reversing device 312 are used in combination with the reinforced support column 316 and the widened panel 315 to obtain a more stable support effect, and can also determine the horizontal line of the device.

[0043] Example 3

[0044] like Figure 5-6 As shown, the reversing device 312 includes a reversing turntable 3121, a central reversing shaft 3122, a closed port 3123, a fixing buckle 3124, and a positioning ring 3125. The closed ports 3123 are fixedly installed at both ends of the central reversing shaft 3122. The reversing turntable 3121 is fixedly installed on one side of one of the closed ports 3123. One end of the fixing buckle 3124 is movably connected to the inside of the positioning ring 3125, and the other end of the fixing buckle 3124 is movably connected to one side of the other closed port 3123. Triangular support plates 3126 are movably installed at both the upper and lower ends of the central reversing shaft 3122. An anti-slip groove 3129 is provided at the junction with the triangular support plate 3126. A through hole 31210 is provided at the center of the central reversing shaft 3122. A connecting rod 3127 is provided inside the through hole 31210. The connecting rod 3127 passes through the central reversing shaft 3122 and the triangular support plate 3126. A limit ring 3128 is threadedly connected at the junction of the connecting rod 3127 and the triangular support plate 3126. One end of the widened panel 315 is fixedly connected to one side of the triangular support plate 3126. The reversing turntable 3121 is fixed in the shape of a rod inside the synchronous support ring 313. The reversing turntable 3121 is located at the center point of the synchronous support ring 313.

[0045] In this embodiment, the reversing device 312 uses a positioning ring 3125 in conjunction with a reversing turntable 3121 at the other end to determine the position of the central reversing shaft 3122. A fixing buckle 3124 enhances the connection tightness with the closed port 3123, thereby fixing the central reversing shaft 3122. During reversing, the drive motor 311 directly drives the reversing turntable 3121 to rotate. As the turntable 3121 rotates, it drives the entire central reversing shaft 3122 to rotate through the closed port 3123, thus changing the angle of the triangular support plate 3126. This, in turn, changes the angle of the workbench body 35. The contact area between the triangular support plate 3126 and the central reversing shaft 3122 is increased by an anti-slip groove 3129, and is further secured by a separate connecting rod 3127. Secondary reinforcement is achieved by limiting the connecting rod 3127 through the limiting ring 3128, connecting the two triangular support plates 3126 to the central reversing shaft 3122. This improves the overall structural strength and prevents excessive weight on one side of the triangular support plate 3126 from damaging the central reversing shaft 3122. The triangular support plate 3126 also reduces the overall weight of the reversing device 312 without affecting the support effect, reducing the difficulty of changing the angle of the workbench 3. When installing some heavy or bulky accessories, it is only necessary to fix one side of the accessory to the lowest position of the workbench body 35, and then return the entire workbench 3 to a horizontal state. The tiltable design allows residue on the surface of the workbench 3 to slide off to one side, speeding up subsequent cleaning.

[0046] Example 4

[0047] like Figure 7 As shown, the locking device 32 includes a limiting frame 321, an extension support plate 322, a support base 323, and an electric telescopic column 324. The extension support plate 322 is fixedly installed on both sides of the limiting frame 321, the support base 323 is fixedly installed on one end of the extension support plate 322, one end of the electric telescopic column 324 is movably installed on the top of the support base 323, the limiting frame 321 is fixedly installed on both sides of the limiting frame 325, the other end of the electric telescopic column 324 is movably installed with a latch 326, the inner wall of the limiting frame 321 is provided with an arc-shaped groove 327, the arc-shaped groove 327 is slidably connected to one end of the limiting slide plate 314, and the other end of the latch 326 is engaged with the outer wall of the reinforcing support column 316.

[0048] In this embodiment, the locking device 32 not only determines the horizontal line of the device but also locks its horizontal state to prevent the worktable 3 from swaying left and right during normal processing. The locking device 32 is powered by an electric telescopic column 324, and the entire device is connected to the support device 31 via a limiting frame 321. The extension support plate 322 and the support base 323 determine the position of the electric telescopic column 324, and the limiting housing 325 accommodates the latch 326. When the movable latch 326 moves, the limiting housing 325 can also calibrate the movement path of the latch 326 to prevent deviation. After the latch 326 is engaged with the gap between the reinforcing support column 316, the widened panel 315 can be restricted to prevent it from rotating. When a change of direction is required, the electric telescopic column 324 drives the latch 326 to move out of the reinforcing support column 316 to release the direction changing device 312. The arc groove 327 is used to cooperate with the limiting slide 314 to determine the rotation path.

[0049] Working principle:

[0050] like Figure 1-7As shown, the spindle box 1 controls the operation of the cutting tool, while the worktable 3 can move on the boring machine body 2 to approach or move away from the spindle box 1. The support platform 33 at the bottom of the worktable 3 has a smaller cross-sectional area than the worktable body 35, thus providing room for changing the angle of the worktable body 35. Combined with the larger edge size of the partition shell 34, the maximum rotation range and angle of the worktable body 35 can be limited. The support device 31 is directly driven by the drive motor 311 to operate the reversing device 312. During the reversing process, the synchronous support rings 313 on both sides can synchronously determine the state of both ends of the worktable 3, avoiding the two ends from being in the same position when adjusting the direction. In cases of inconsistent rotation amplitude, the limiting slide 314 can provide secondary limiting for the rotation path to prevent misalignment. Simultaneously, both sides of the reversing device 312 utilize a combination of reinforced support columns 316 and widened panels 315 to achieve a more stable support effect. The locking device 32 is powered by the electric telescopic column 324, and the entire unit is connected to the support device 31 via the limiting frame 321. The extended support plate 322 and support base 323 determine the position of the electric telescopic column 324. The limiting housing 325 accommodates the latch 326. When the electric telescopic column 324 pushes the latch 326 to move, the limiting housing 325... 25 can also calibrate the movement path of the latch 326 to prevent deviation. After the latch 326 is engaged with the gap between the reinforcing support column 316, the widened panel 315 can be restricted to prevent rotation. When a change of direction is required, the electric telescopic column 324 drives the latch 326 to move out of the reinforcing support column 316 to release the direction-changing device 312. The arc groove 327 is used to cooperate with the limit slide 314 to determine the rotation path. During the change of direction, the drive motor 311 directly drives the direction-changing turntable 3121 to rotate. When the direction-changing turntable 3121 rotates, it will drive the entire center through the closed port 3123. The reversing shaft 3122 rotates, thereby changing the angle of the triangular support plate 3126, which in turn changes the angle of the main body of the worktable 35. The contact area between the triangular support plate 3126 and the central reversing shaft 3122 is increased by the anti-slip groove 3129, and is further reinforced by a separate connecting rod 3127. This connecting rod 3127 is limited by the limiting ring 3128, so that the two triangular support plates 3126 and the central reversing shaft 3122 are connected together. This helps to improve the overall structural strength and prevents the central reversing shaft 3122 from being damaged due to excessive mass on one side of the triangular support plate 3126.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
