A surface cutting device for machining automotive parts

Abstract

This utility model relates to the field of automotive parts processing technology, specifically to a surface cutting device for automotive parts processing. A first slide table is bolted to the bottom of the housing, and first slide rails are installed on both sides of its top. A first internally threaded block with a first sliding clamp is slidably mounted on the slide rails. The internally threaded block is embedded in the inner cavity of the first slide table and threadedly engages with a first threaded rod. Both ends of the first threaded rod are supported by bearings on the inner wall of the slide table, and one end of the rod passes through the slide table and the rear wall of the housing before connecting to a first motor fixed externally to the housing. A mold table is bolted to the top of the internally threaded block. When the first motor drives the threaded rod to rotate, the internally threaded block drives the mold table to move laterally along the slide rails. This design, by placing the drive motor outside the housing and utilizing the bearing support structure through the threaded rod to achieve dynamic sealing isolation, completely blocks the erosion of the motor by cutting fluid, moisture, and debris in the processing area, thereby significantly extending the service life of the equipment and ensuring the workpiece feeding accuracy under humid and cold conditions.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a surface cutting device for automotive parts processing. Background Technology

[0002] ① In traditional automotive parts cutting equipment, a three-axis slide system is used inside the housing to position the tool. The X-axis and Y-axis slides are horizontally arranged at the bottom of the housing, while the Z-axis slide is vertically installed on the side. During the cutting process, the continuous spraying of cutting fluid causes water to accumulate and vaporize in the bottom area of ​​the housing for a long time. Since the drive motors of the X-axis and Y-axis slides are integrated inside the slide structure at the bottom of the housing, the motor body and its transmission components are directly exposed to the water and vapor environment, which leads to faults such as coil moisture short circuit, bearing corrosion and slide rail lubrication failure, significantly shortening the service life of the equipment.

[0003] ② To address the need for bottom motor protection, some improved solutions raise the mounting positions of the X-axis and Z-axis slides to the side wall of the housing: the X-axis slide is horizontally fixed to the side wall to drive the tool's forward and backward displacement, and the Z-axis slide is vertically mounted on the X-axis slide to control the tool's lifting and lowering; this structure raises the X-axis and Z-axis motors away from the water accumulation area at the bottom of the housing, using the height difference to form a physical isolation layer, effectively reducing the probability of both coming into contact with the cutting fluid, thereby reducing motor failures caused by liquid corrosion.

[0004] ③However, the Y-axis slide table needs to support the workpiece carrier platform and must remain at the bottom of the housing; although its drive motor uses a sealed housing, the transmission components such as the threaded rod, internal threaded block and sliding clamp are completely submerged in the liquid at the bottom of the housing; after long-term operation, the cutting fluid seeps into the gaps in the transmission structure, causing the threaded pair to rust and jam, and the slide rail to wear more rapidly, forcing the equipment to be frequently stopped for disassembly and maintenance; this kind of reliability decline caused by the full immersion loss of the transmission mechanism urgently needs to be solved by combining the external motor and the physical isolation structure. Utility Model Content

[0005] The purpose of this invention is to provide a surface cutting device for processing automotive parts, which solves the problem that traditional cutting devices are susceptible to corrosion from water vapor and cutting fluid when processing in humid and cold environments or using coolant, resulting in shortened equipment life and reduced operational stability.

[0006] To achieve the above objectives, this utility model provides a surface cutting device for processing automotive parts, including a first slide table. The first slide table is bolted to the bottom surface inside a housing. First slide rails are bolted to both sides of the top of the first slide table. First sliding clamps are slidably mounted on the outer sides of the first slide rails. A first internal threaded block is fixedly mounted between the first sliding clamps. The first internal threaded block is slidably disposed inside the first slide table, and a first threaded rod is threadedly mounted in its middle. The two ends of the first threaded rod are respectively mounted to the two ends inside the first slide table via bearings. One end of the first threaded rod extends through the first slide table and the rear side wall of the housing and is connected to a first motor. The first motor is bolted to the outer side of the first slide table. A mold table is bolted to the top of the first internal threaded block.

[0007] The box has a window on one side, and a second slide is bolted to the rear wall inside the box. A second slide rail is bolted to both sides of the top of the second slide, and a second sliding clamp is slidably installed on the outer side of the second slide rail.

[0008] A second internal threaded block is fixedly installed between the second sliding clamps. The second internal threaded block is slidably disposed in the second slide table, and a second threaded rod is installed in the middle of it by means of threads. The two ends of the second threaded rod are respectively installed at both ends inside the second slide table by bearings.

[0009] The second threaded rod has one end that passes through and extends to the outside of the second slide table and is connected to the output end of the second motor. The second motor is installed on the outside of the second slide table by bolts. The top of the second internal threaded block is fitted with a vertically arranged third slide table by bolts.

[0010] The length extension direction of the third slide is perpendicular to the length extension direction of the first slide. The top two sides of the third slide are respectively bolted with third slide rails, and third sliding clamps are slidably installed on the outer side of the third slide rails.

[0011] A third internal threaded block is fixedly installed between the third sliding clamps. The third internal threaded block is slidably disposed inside the third slide table, and a third threaded rod is installed in the middle of it through a thread. The two ends of the third threaded rod are respectively installed inside the third slide table through bearings.

[0012] The third threaded rod has one end that passes through and extends to the outside of the third slide table and is connected to the third motor. The third motor is connected to the outside of the third slide table by bolts. The top of the third internal threaded block is fitted with an L-shaped plate by bolts.

[0013] The L-shaped plate has a drive motor bolted to its top. The output end of the drive motor passes through the L-shaped plate and is equipped with a chuck. A cutting tool is held in the chuck.

[0014] This utility model discloses a surface cutting device for processing automotive parts. A first slide table is bolted to the bottom surface of the housing. First slide rails are symmetrically arranged on both sides of the top of the slide table. A first internally threaded block with a first sliding clamp is slidably mounted on the two slide rails. The internally threaded block is embedded in the internal cavity of the first slide table and is connected to a first threaded rod that passes horizontally through it via threaded engagement. The two ends of the threaded rod are supported by bearings at both ends of the first slide table cavity. One end extends and penetrates the first slide table and the rear side wall of the housing, connecting to the output end of a first motor fixed to the outside of the first slide table. A mold table for supporting the workpiece is rigidly mounted on the top of the first internally threaded block via bolts.

[0015] Once the workpiece is fixed on the mold table, the first motor drives the first threaded rod to rotate, forcing the first internal threaded block to slide along the first slide rail in a directional manner. Simultaneously, this drives the mold table and the workpiece to move horizontally (Y-axis) along the bottom surface of the housing. During this process, the first motor is not placed in the humid environment inside the housing, but is completely placed outside the dry area on the rear side wall of the housing. At the same time, the threaded rod penetrating the housing forms a sealed isolation structure with the housing wall through the bearing. This arrangement isolates the motor's electromagnetic coil from the precision bearings, preventing cutting fluid splashes, moisture corrosion, and metal shavings from intrusion, eliminating the risk of short circuits, leakage, or bearing corrosion failure caused by moisture in traditional built-in motors.

[0016] In addition, the rigid connection structure between the first internal thread block and the mold table ensures that there is no mechanical backlash during the workpiece translation process, thus guaranteeing the positioning accuracy of the Y-axis feed; and the installation method in which the first slide is fixed to the bottom of the box forms a stable basic support platform, avoiding displacement deviation caused by processing vibration.

[0017] In this structure, on the basis of the basic protection of the sealed box, the external power transmission design of the Y-axis drive system allows the key drive unit to be removed from the high humidity and high pollution processing environment, which significantly improves the durability and operational reliability of the equipment when processing under long-term wet and cold conditions or using coolant, while ensuring the repeatability and positioning accuracy of the workpiece feed motion.

[0026] This utility model provides a surface cutting device for machining automotive parts. The device's main body is a housing 108, with a window 125 on one side for workpiece installation and observation. A second slide 109 is bolted to the rear sidewall of the housing 108. Second slide rails 110 are bolted to both sides of the top of the second slide 109. Second sliding clamps 111 are slidably mounted on the outer sides of the second slide rails 110. A second internally threaded block 112 is fixedly installed between the second sliding clamps 111. The second internally threaded block 112 is slidably disposed within the internal space of the second slide 109. A second threaded rod 113 is threadedly installed in the middle of the second internally threaded block 112. The two threaded rods 113 are respectively mounted at both ends inside the second slide table 109 via bearings. One end of the second threaded rod 113 passes through and extends to the outside of the second slide table 109. This extended end is connected to the output end of the second motor 114. The second motor 114 is bolted to the outside of the second slide table 109 to achieve precise linear displacement of the second internal threaded block 112 and its associated components along the track of the second slide table 109. A vertically arranged third slide table 115 is bolted to the top of the second internal threaded block 112. Third slide rails 116 are bolted to both sides of the top of the third slide table 115. Third sliding clamps 117 are slidably mounted on the outside of the third slide rails 116. A third internal threaded block 118 is fixedly mounted between the third sliding clamps 117. The threaded block 118 is slidably disposed within the internal space of the third slide table 115. A third threaded rod 119 is threadedly mounted in the middle of the third internal threaded block 118. The two ends of the third threaded rod 119 are respectively mounted inside the third slide table 115 via bearings. One end of the third threaded rod 119 passes through and extends to the outside of the third slide table 115. This extended end is connected to a third motor 120, which is bolted to the outside of the third slide table 115 to achieve horizontal displacement of the third internal threaded block 118 and its associated components. An L-shaped plate 121 is bolted to the top of the third internal threaded block 118. A drive motor 122 is bolted to the top of the L-shaped plate 121. The output end of the drive motor 122 passes through the L-shaped plate 121 and is connected to a chuck 12. 3. A cutting tool 124 is clamped inside the chuck 123 to achieve cutting power output; a first slide 101 is bolted to the bottom surface of the housing 108. The length extension direction of the first slide 101 is perpendicular to the length extension direction of the third slide 115. A first slide rail 102 is bolted to both sides of the top of the first slide 101. A first sliding clamp 103 is slidably installed on the outer side of the first slide rail 102. A first internal thread block 104 is fixedly installed between the first sliding clamps 103. The first internal thread block 104 is slidably disposed in the internal space of the first slide 101. A first threaded rod 105 is threadedly installed in the middle of the first internal thread block 104. The two ends of the first threaded rod 105 are respectively installed inside the first slide 101 by bearings.One end of the first threaded rod 105 extends through the first slide table 101 and the rear side wall of the housing 108. This through end is connected to the first motor 106, which is bolted to the outside of the first slide table 101 to ensure that the drive components are isolated from the processing environment. A mold table 107 is bolted to the top of the first internal threaded block 104. The mold table 107 is used to support and fix the automotive part to be processed.

[0027] Working principle: The entire device is placed inside a sealed box (108), with an operation window (125) on one side for easy installation of workpieces and observation of the processing. During operation, the operator fixes the automotive parts to be processed onto the mold table (107) on the bottom surface inside the box (108). Subsequently, the mold table (107) begins to move under the drive of the first slide (101): the first motor (106) installed on the outside of the box (108) starts, driving the first threaded rod (105) that penetrates the rear wall of the box (108) to rotate. This rotational motion drives the first internal threaded block (104) that is threaded to it to slide smoothly along the first slide rail (102), and finally the first internal threaded block (104) installed on the top of the first internal threaded block (104) slides smoothly. The mold table (107) and the workpiece on it are horizontally translated along the width direction (Y-axis) of the bottom surface inside the box (108); this movement realizes the lateral positioning of the workpiece; the design of the first motor (106) in the dry environment outside the box (108) prevents the corrosion of water vapor and splash liquid generated during cutting inside the box, significantly improving the durability of key drive components; after the workpiece is positioned, the cutting unit starts to work; the second slide (109) mounted on the side wall of the rear of the box (108) is the first to move: the second motor (114) mounted on its outer side drives the second threaded rod (113) that passes through the slide to rotate, driving the second internal threaded block (112) along the second slide rail (110) on the top of the second slide (109). Sliding; Since the top surface of the second internal thread block (112) is vertically fixed to the third slide (115) by bolts, this movement drives the entire third slide (115) and all cutting components on it (including the third slide (115), L-shaped plate (121), drive motor (122) and tool (124)) to move horizontally back and forth along the length direction (X-axis) parallel to the side wall of the box (108) to adjust the cutting starting position; The design of the second slide (109) and its associated third slide (115) being suspended and fixed to the side wall of the box (108) completely lifts it off the ground, effectively avoiding the water accumulation and debris accumulation areas common in the processing area, and greatly reducing the risk of moisture damage; Then, vertical The cutting assembly on the third slide (115) starts to move: the third motor (120) on the outside of the third slide (115) drives the third threaded rod (119) inside to rotate, and through thread engagement, drives the third internal threaded block (118) to slide along the third slide rail (116) on the top of the third slide (115), driving the L-shaped plate (121), drive motor (122), chuck (123) and tool (124) fixed on its top to move up and down along the vertical direction of the third slide (115) (i.e., the Z-axis direction perpendicular to the bottom surface of the box (108)), thereby accurately setting the cutting depth of the tool (124); the drive component is in a side-mounted position and also benefits from the structural isolation protection of the lifting installation;Once the tool (124) height is set, the drive motor (122) mounted on the L-shaped plate (121) starts, and the high-speed rotating output end drives the chuck (123) and the clamped tool (124) to perform cutting. At this time, the X, Y, and Z axes work together to precisely control the machining trajectory: the second slide (109) drives the entire cutting assembly to move horizontally along the length of the housing (108) (X-axis movement); the third slide (115) drives the tool (124) to feed vertically (Z-axis lifting and lowering, adjusting the cutting depth); the first slide (101) drives the workpiece to move laterally (Y-axis feeding, realizing the workpiece's feeding motion). The directions of these three movements are perpendicular to each other, allowing the tool (124) to cover any position on the workpiece surface and complete complex cutting paths. Compared with traditional technology, the second slide (109) and the third slide (115) of this device are all fixed to the rear side wall inside the housing (108) by bolts, rather than the traditional ground. In this integrated configuration, the key transmission mechanisms are elevated to the side wall of the housing (108), keeping them away from the area on the ground where cutting fluid, moisture, and debris are most likely to accumulate, effectively blocking moisture from rising upwards. The first motor (106) of the first slide (101) that drives the workpiece to translate along the Y-axis is specifically designed to operate in a dry environment outside the housing (108). This completely isolates the sensitive parts of the drive motor from the moisture-filled machining housing (108), avoiding the potential for coil short circuits and bearing corrosion caused by sealing failures or humid environments that can occur with traditional internally mounted motors. The layout adjustment of the three slide drive systems (the X-axis and Z-axis drive mechanisms are elevated and suspended on the side, and the Y-axis driver is externally mounted) creates a synergistic sealing and protection effect, significantly improving the reliability and service life of the entire device in wet and cold cutting environments or when using coolant. Combined with the sealed environment of the housing (108), this ensures a smooth and precise machining process.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
