Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a workbench of a milling machine. Background Art

[0002] In the hardware workpiece processing industry, milling machines that use milling cutters to process various surfaces of workpieces are very common equipment. During processing, it is necessary to use a workpiece fixture to clamp the workpiece on the workbench surface to keep the workpiece stable during processing in the specified position and prevent the workpiece from moving during the processing. When the workpiece fixture is installed on the workbench surface, it needs to be calibrated and positioned so that the edges of the workpiece fixture are parallel to the horizontal and vertical directions, and the workpiece fixture is completely facing the processing position of the milling machine without skewing or deflection to ensure the processing accuracy.

[0003] When calibrating and positioning the workpiece fixture, it is necessary to first lock the workpiece fixture to the T-shaped locking slot on the workbench table with a bolt, and then rotate the workpiece fixture with the bolt as the center point. It is necessary to use a calibration table to repeatedly adjust until the edge of the workpiece fixture is parallel to the horizontal and vertical directions. This process is relatively time-consuming, and the efficiency of calibration and positioning needs to be improved. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a workbench of a milling machine to solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the present invention shown in and described with reference to the accompanying drawings are merely exemplary, and the present invention is not limited to these embodiments.

[0029] Here, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solutions according to the present invention are shown in the drawings, and other less relevant details are omitted.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a workbench of a milling machine, which includes a workbench table 1, a workpiece fixture 2 and an auxiliary alignment seat 3.

[0031] The workbench surface 1 is provided with a plurality of equally spaced and parallel locking grooves 101, wherein the locking grooves 101 extend horizontally from one end of the workbench surface 1 to the other end of the workbench surface 1;

[0032] The workpiece fixture 2 is provided with a plurality of bolt holes 20 for being fastened to the fastening grooves 101 of the workbench table 1 by bolts, so that the workpiece fixture 2 is fixed to the workbench table 1;

[0033] The auxiliary alignment seat 3 includes a transverse ruler seat 31 and a longitudinal ruler seat 32 arranged perpendicular to each other, one end of the transverse ruler seat 31 and the longitudinal ruler seat 32 are connected to each other, the longitudinal ruler seat 32 extends longitudinally, perpendicular to the length direction of the locking groove 101, the transverse ruler seat 31 and the longitudinal ruler seat 32 are each provided with a length scale on the top surface thereof, and the bottom of the longitudinal ruler seat 32 is downwardly connected to a plurality of transfer clamps 321 corresponding to the locking groove 101 one by one, the transfer clamps 321 are embedded in the locking groove 101, and the transfer clamps 321 can slide along the locking groove 101, so that the auxiliary alignment seat 3 can be laterally translated along the workbench surface 1.

[0034] When the workbench provided by the embodiment of the present invention is used and the workpiece fixture 2 needs to be calibrated and positioned, the auxiliary alignment seat 3 can be horizontally translated along the workbench surface 1 to the required position on the workbench surface 1, so that the longitudinal ruler seat 32 of the auxiliary alignment seat 3 abuts against the workpiece fixture 2, and then the workpiece fixture 2 is rotated so that its edge is aligned with the longitudinal ruler seat 32 to ensure that the four edges of the workpiece fixture 2 are parallel to the horizontal and vertical directions respectively without being skewed. Subsequently, the workpiece fixture 2 is moved longitudinally along the longitudinal ruler seat 32, and the width of the locking groove 101 is matched according to the pre-designed position layout of the bolt holes 20 of the workpiece fixture 2. As long as it is ensured that the workpiece fixture 2 does not have an angular deviation, the multiple bolt holes 20 of the workpiece fixture 2 can be aligned with the locking groove 101 at the same time. At this time, the bolts are locked one by one, and the calibration, positioning and fixation of the workpiece fixture 2 on the workbench surface 1 can be quickly completed without the need for repeated adjustment using a calibration meter, and the operation efficiency is higher.

[0035] The scale markings on the horizontal ruler seat 31 and the vertical ruler seat 32 not only facilitate the workpiece fixture 2 to determine its position, but also facilitate the operator to determine the structural dimensions of the workpiece clamped by the workpiece fixture 2. Because a lot of metal scraps are generated during milling and other processing operations, before placing the workpiece fixture 2 on the workbench table 1, the auxiliary alignment seat 3 is moved horizontally across the workbench table 1 to sweep away the scraps on the workbench table 1, keeping the workbench table 1 clean and tidy, and preventing the scraps from affecting the calibration and positioning of the auxiliary alignment seat 3. In addition, since the transfer clamp 321 slides along the locking groove 101, the scraps in the locking groove 101 can be swept out at the same time.

[0036] Furthermore, the workbench includes a waste chip receiving groove 4. A mounting socket 102 is provided at one end of the workbench surface 1. The waste chip receiving groove 4 is removably inserted into the workbench surface 1 and fixed thereto via a strip 41 corresponding to the mounting socket 102. One side wall of the waste chip receiving groove 4 abuts the workbench surface 1. Thus, the auxiliary alignment seat 3 can be laterally translated from the end of the workbench surface 1 away from the waste chip receiving groove 4 to the end abutting the waste chip receiving groove 4, sweeping waste chips generated during processing into the waste chip receiving groove 4 for collection, facilitating subsequent removal of the waste chip receiving groove 4 for cleaning.

[0037] Specifically, in order to allow the waste chips in the high locking groove 101 to fall into the low waste chip receiving groove 4 , the side wall edge of the waste chip receiving groove 4 is attached to the workbench surface 1 at a height lower than the bottom of the locking groove 101 .

[0038] Combine Figure 3 and Figure 4 As shown, the bottom of the transfer clamp 321 is connected to a sleeve pin 322, and the sleeve pin 322 is outer-connected with an elastic brush head 323. The locking groove 101 is a T-shaped groove, and ordinary cleaning methods are difficult to clean deeply into the groove. The elastic brush head 323 fits well with the inner wall of the locking groove 101, which can avoid leaving dead corners and achieve a cleaner and more thorough cleaning effect.

[0039] Exemplarily, the elastic brush head 323 is a sponge block or a silicone block. Such materials fit more closely with the locking groove 101 and are less likely to scratch the inner wall of the locking groove 101. They are common cleaning tool materials.

[0040] A slide groove 310 is formed on the transverse ruler seat 31, and one end of the longitudinal ruler seat 32 is slidably connected to the slide groove 310 of the transverse ruler seat 31, so that the transverse ruler seat 31 can be slid as needed and moved relatively to the left or right side of the longitudinal ruler seat 32.

[0041] A ball screw 5 is connected to the bottom of the workbench surface 1, and a rotating handle 51 is provided at one end of the ball screw 5. The ball screw 5 drives the entire workbench surface 1 to move horizontally to adjust the processing position of the workpiece in the horizontal direction.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0043] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
