Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and more specifically, to a worktable structure for a multi-head grinding machine. Background Technology

[0002] Currently, in the grinding of linear guideways, the linear guideway needs to be clamped onto a worktable. During the grinding process, the linear guideway moves with the worktable in the Y direction, while the grinding head can move in the X and Z directions, thus completing the grinding of the linear guideway surface. To improve the grinding efficiency of linear guideways, many grinding machines are now equipped with vertical and horizontal grinding heads to achieve multi-face grinding in one operation. However, existing grinding machine worktables cannot simultaneously mount vertical and horizontal grinding heads, nor can they simultaneously dress the vertical and horizontal grinding heads. For example, Chinese patent application number 2005100608893 discloses a grinding machine for processing linear guideways, consisting of a bed, a worktable mounted on the bed, and a fixture on the worktable. This worktable cannot simultaneously mount vertical and horizontal grinding heads, nor can it simultaneously dress the vertical and horizontal grinding heads. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a multi-head grinding machine worktable structure, on which vertical grinding heads and horizontal grinding heads can be installed simultaneously, and the vertical grinding heads and horizontal grinding heads can be dressed at the same time.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-head grinding machine worktable structure, including a fixed base and a slide table, the slide table being slidably mounted on the fixed base, a horizontal grinding support and two vertical grinding supports being provided on the fixed base, the two vertical grinding supports being arranged opposite to each other on both sides of the fixed base, a vertical dresser and a horizontal dresser being mounted on the slide table, the vertical dresser being provided with a vertical dressing wheel, and the horizontal dresser being provided with a horizontal dressing wheel.

[0005] The slide table is slidably mounted on the fixed base. The linear guide rail is mounted on the slide table during grinding, and slides together with the slide table for grinding. The fixed base is equipped with a horizontal grinding support and two vertical grinding supports, facilitating the installation of both horizontal and vertical grinding heads. A vertical dresser and a horizontal dresser are mounted on the slide table, facilitating the dressing of both vertical and horizontal grinding heads.

[0006] The multi-head grinding machine worktable structure of this patent application allows for the simultaneous mounting of vertical and horizontal grinding heads on the worktable, and enables the simultaneous dressing of both vertical and horizontal grinding heads.

[0007] Preferably, limit buffer rods are installed at both ends of the fixed base, and the limit buffer rods limit and buffer the slide.

[0008] The limit buffer rod plays a limiting and buffering role for the slide table, preventing the slide table from sliding too far and helping to ensure the safety of the grinding machine.

[0009] Preferably, a mounting cylinder corresponding to the limiting buffer rod is installed on the fixed base, a buffer spring is installed inside the mounting cylinder, one end of the limiting buffer rod is movably inserted into the mounting cylinder, and the buffer spring abuts against the limiting buffer rod.

[0010] When the limiting buffer rod is impacted by the slide, it moves and compresses the buffer spring, thus limiting and buffering the slide. The end of the limiting buffer rod is installed in the mounting cylinder, ensuring smooth and reliable movement.

[0011] Preferably, a contact sensor is installed on the mounting cylinder, and the limit buffer rod is engaged with the contact sensor.

[0012] In the initial state, the limit buffer rod is close to the contact sensor. When the limit buffer rod is impacted and moves, it separates from the contact sensor. At this time, the contact sensor detects the signal and transmits it to the grinding machine's control system so that the grinding machine control system can take emergency braking measures.

[0013] Preferably, an impact block is installed at the end of the slide, and the impact block is set in correspondence with the limit buffer rod.

[0014] Impact blocks are installed on the slide to strike the limit buffer rod, thus protecting the slide.

[0015] Preferably, a fixture seat can be detachably installed on the slide, an electromagnetic chuck is installed on the fixture seat, a magnetic strip is installed on the electromagnetic chuck, and a linear guide rail is mounted on the magnetic strip.

[0016] The clamp base is detachably mounted on the slide for easy replacement. The electromagnetic chuck provides magnetic attraction, and through the magnetic conduction of the magnetic strip, it achieves reliable engagement and positioning of the linear guide rail.

[0017] Preferably, a linear motor is installed at the bottom of the slide table, and several spaced magnetic plates are installed on the fixed base; two linear slide rails are provided on the fixed base, and several linear sliders are installed on the linear slide rails, with the linear sliders being securely connected to the slide table.

[0018] The linear motor and magnetic plate work together to move the slide, which in turn drives the slide table to slide. The slide table is fixedly connected to the linear slider and moves along the linear guide rail, ensuring the accuracy and stability of the slide table's movement.

[0019] Preferably, both the horizontal mill support and the vertical mill support are hollow structures, and positioning slots are provided on the upper surface of both the horizontal mill support and the vertical mill support.

[0020] Hollow horizontal and vertical mill supports save materials and reduce the weight of the fixed base, while the positioning slots facilitate the installation and positioning of other components.

[0021] Preferably, the vertical dresser is equipped with a vertical motor, the output shaft of which is connected to the vertical dressing wheel, and a sealing cover is fitted over the output shaft of the vertical motor, which is connected to the end of the vertical motor.

[0022] The vertical motor drives the vertical dressing wheel to rotate, and the sealing cover protects the vertical motor, preventing grinding and grinding fluid from entering the vertical motor.

[0023] Preferably, the horizontal dresser is equipped with a horizontal motor, the output shaft of which is connected to the horizontal dressing wheel, and a protective cover is fitted over the output shaft of the horizontal motor, which is connected to the end of the horizontal motor.

[0024] The horizontal motor drives the horizontal dressing wheel to rotate, and the protective cover protects the horizontal motor, preventing grinding and grinding fluid from entering the interior of the horizontal motor.

[0025] Compared with the prior art, the beneficial effects of this utility model are: (1) The multi-head grinding machine worktable structure of this patent application enables vertical grinding heads and horizontal grinding heads to be installed on the worktable at the same time, and can simultaneously achieve the dressing of vertical grinding heads and horizontal grinding heads; (2) The limiting buffer rod plays a limiting buffer role on the slide table, preventing the slide table from sliding too far, which is conducive to ensuring the safety of the grinding machine; (3) The impact block is installed on the slide table, and the impact block hits the limiting buffer rod, which plays a protective role on the slide table.
