Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts processing equipment, and particularly to a horizontal milling groove device for automobile parts. Background Technique

[0002] Automobile parts are various units that make up an automobile as a whole and products that serve the automobile. There is a wide variety of automobile parts. With the improvement of people's living standards, people's consumption of automobiles is increasing, and the market for automobile parts has become larger and larger. In recent years, automobile parts manufacturing plants have also been developing rapidly. Automobile parts that require milling groove processing mainly include engine blocks, transmission housings, chassis components, wheels, etc.

[0003] For milling groove processing, there are fixed requirements for the groove size. By setting a positioning structure in the milling groove direction, the horizontal movement of the workpiece during processing can be avoided. However, the control in the vertical direction is more difficult. For shell-like parts, the vibration generated during the milling groove process easily causes the parts to have a vertical displacement, resulting in an uneven bottom wall of the milled groove and difficult error control. Therefore, we have proposed a horizontal milling groove device for automobile parts. Summary of the Invention

To ensure synchronous movement, the linear guide rails within the group can be synchronously driven through a gear belt. The two linear guide rails 2 15 are driven by a motor 2. A gantry 3 is arranged between the two linear guide rails 2 15. An electric drive rail 4 is arranged on the gantry 3, and a milling groove mechanism 5 is arranged on the electric drive rail 4 for milling groove processing of workpieces. Two sliding components 6 are arranged between the two linear guide rails 1 2 for workpiece positioning, and a multi-point positioning mechanism 7 is arranged on the inner bottom wall of the processing table 1 for supporting the bottom of the workpiece.

[0023] The sliding component 6 includes a sliding rod 61, a positioning groove 62, a spring groove 63, a compression spring 64, an installation groove 65, a pressure sensor 66, and a positioning plate 67. The two ends of the sliding rod 61 are respectively fixedly connected to the sliders of the two linear guide rails 1 2. Positioning grooves 62 are formed on the opposite sides of the two sliding rods 61. Two spring grooves 63 are symmetrically formed on the bottom wall of the positioning groove 62. A positioning plate 67 is inserted into the positioning groove 62. The positioning plate 67 is movably connected to the bottom wall of the spring groove 63 through a compression spring 64. An installation groove 65 is formed in the middle of the bottom wall of the positioning groove 62, and a pressure sensor 66 is fixedly installed in the installation groove 65. The detection end of the pressure sensor 66 extends out of the installation groove 65 and contacts the positioning plate 67.

[0024] The multi-point positioning mechanism 7 includes a positioning table 71, a hydraulic cylinder 1 72, a hanging plate 73, a through hole 74, a positioning rod 75, a positioning ring 76, a tension spring 77, and a through hole 78. The positioning table 71 is fixedly connected to the inner bottom wall of the processing table 1 through a support rod. The hydraulic cylinder 1 72 is fixedly installed on the lower surface of the positioning table 71. The output end of the hydraulic cylinder 1 72 is fixedly connected to the hanging plate 73. A through hole 74 is formed on the hanging plate 73. The positioning rod 75 is inserted into the through hole 74. The bottom end of the positioning rod 75 is fixedly connected to the positioning ring 76. The upper surface of the positioning ring 76 is movably connected to the lower surface of the hanging plate 73 through a tension spring 77. A through hole 78 is formed on the positioning table 71 corresponding to the position of the positioning rod 75. The positioning rod 75 passes through the through hole 78 and extends to the upper side of the positioning table 71. A plurality of limiting rods 711 are provided and arranged in a matrix. The limiting rods 711 can be divided into multiple groups according to regions. Each group corresponds to a hanging plate 73 driven by a hydraulic cylinder 1 72. During actual operation, when fixing the workpiece, only the limiting rods 711 in the corresponding region are driven to move upward to support.

[0025] The multi-point positioning mechanism 7 further includes a positioning hole 79, a positioning cavity 710, a limiting rod 711, a cylinder 712, and a limiting block 713. The positioning cavity 710 is opened in the positioning table 71 and communicates with the through hole 78. The positioning hole 79 is opened in the side wall of the positioning table 71 and communicates with the inside of the positioning cavity 710. The limiting rod 711 is inserted into the positioning hole 79 and extends into the positioning cavity 710. The cylinder 712 is fixedly installed on the side wall of the positioning table 71 and fixedly connected to one end of the limiting rod 711. A limiting block 713 is fixedly connected to the limiting rod 711 at a position corresponding to the positioning rod 75. The cylinder 712 drives the limiting rod 711 to enable the limiting block 713 to press against the positioning rod 75 to fix it.

[0026] In the middle of the upper surface of the positioning table 71, a support plate 9 is fixedly connected through a second hydraulic cylinder 8. A hole for the positioning rod 75 to pass through is opened in the support plate 9.

[0027] At the top of the positioning rod 75, a support block 10 is provided for supporting the workpiece. The support block 10 is a hard block. The main purpose is to adapt to the shape of the bottom of the workpiece to ensure there are contact points and avoid unstable support points caused by the edge of the positioning rod 75 contacting the workpiece.

[0028] A number of buffer cavities 11 are opened in the positioning rod 75. An installation hole 12 is opened at the top of the positioning rod 75 and communicates with the buffer cavity 11. An absorption vibration block 13 is inserted into the installation hole 12. The top of the absorption vibration block 13 extends above the positioning rod 75. The bottom of the absorption vibration block 13 extends into the buffer cavity 11 and is fixedly connected to one end of a spiral rod 14. The other end of the spiral rod 14 contacts the bottom wall of the buffer cavity 11. The buffer cavity 11 is filled with hydraulic oil. The vibration during the processing is transmitted to the hydraulic oil through the absorption vibration block 13 and the spiral rod 14, converting the kinetic energy into the internal energy of the hydraulic oil.

[0029] When the equipment works, the second hydraulic cylinder 8 rises to the height of the sliding assembly 6. The workpiece to be processed is placed on the upper surface of the support plate 9. The first motor drives the first linear guide 2 to drive the two sliding assemblies 6 to move towards the workpiece. The two positioning plates 67 clamp the workpiece. The pressure applied to the positioning plates 67 is transmitted to the pressure sensor 66 until the positioning plates 67 contact the bottom wall of the positioning groove 62. When the pressure monitored by the pressure sensor 66 reaches the preset value, the first motor stops to lock the positions of the two sliding rods 61.

[0030] The first hydraulic cylinder 72 drives the hanging plate 73 to move upward, so that the top of the positioning rod 75 contacts the bottom of the workpiece. The tension spring 77 is compressed. Multiple positioning rods 75 contact the bottom of the workpiece to complete multi-point support. The first hydraulic cylinder 72 stops to lock the position. The cylinder 712 works to push the limiting rod 711 to make the limiting block 713 press on the side wall of the positioning rod 75 to complete the fixation of the position of the positioning rod 75. Subsequently, the second hydraulic cylinder 8 drives the support plate 9 to move downward to separate from the workpiece.

[0031] The linear guide rail two 15 drives the gantry 3 to move horizontally, and the electric drive guide rail 4 drives the milling groove mechanism 5 to adjust up and down, so as to machine the fixed workpiece with a milling groove.

The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
