Description

Processing device for large and long rollers of treadmill

【Technical field】

The utility model relates to a mechanical device, in particular to a processing device specially used for processing large and long treadmill rollers.

【Background technique】

We know that many large and long rollers are often used on a treadmill. When the current processing equipment is processing a workpiece with a large and long roller, because the workpiece is relatively long, it is necessary for the sub-spindle to clamp 95% of the outer diameter of the workpiece. contact surface, so that when the workpiece is clamped, the workpiece crosses the sub-spindle located in the middle of the machine tool to make the spindle clamp support the inner hole of the workpiece. Machining is done. This type of product is traditionally supported by a center frame. The spindle clamps the workpiece to rotate. After the workpiece rotates, the three support points of the center frame are fixed, so the high-speed rotation of the workpiece will easily wear the three support points of the center frame. Manual adjustment, when the adjustment is not good, the rejection rate is particularly high, so the current processing equipment has low work efficiency, high production cost, and is not easy to control.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a processing device for large and long rollers of treadmills with reasonable structure, convenient operation and low production and use costs, so as to realize high precision, high quality and high efficiency of products.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A processing device for a large and long drum of a treadmill, comprising a bed, on the upper part of the bed a slant platform inclined to the operator is provided, at the front end of the bed a head box and a drive on the head box are arranged. The main shaft motor that the main shaft rotates is respectively provided with a sub main shaft seat for installing a sub main shaft and a ejector seat for installing a hydraulic ejector pin on the middle and tail parts below the inclined table. The main shaft is coaxial, and the sub-spindle seat and the ejector rod seat can slide along the Z-axis lower track of the inclined table; the sub-spindle rotates in the shaft hole of the sub-spindle seat, and the workpiece is clamped by the hydraulic system; The middle part above the ramp is provided with a workbench for installing cutting tools, and the workbench includes a lower slide that slides along the Z-axis upper track of the ramp and an upper slide that slides along the lower slide in the X-axis direction; The upper and lower tables are driven by the X-axis screw and the Z-axis screw respectively.

In an improved solution to the processing device for the above-mentioned large and long drum of the treadmill, the cutting tool is installed on the workbench through a turret that can rotate 360 degrees on the workbench.

Compared with the prior art, the beneficial effects of the utility model are: 1) When the auxiliary spindle is clamped in the middle of the workpiece to assist clamping, it is clamped by a hydraulic system, and the auxiliary spindle can be clamped in the auxiliary spindle. The shaft hole of the main shaft seat rotates with the workpiece, so that the workpiece will not be pinched, and the wear of the sub-spindle is relatively small, so there is no need for frequent maintenance of the sub-spindle, so the utility model has a reasonable structure and low production and use costs; 2) , Moreover, since the sub-spindle seat for installing the sub-spindle and the ejector seat for installing the hydraulic ejector rod are installed obliquely on the inclined table of the operator, this can make the workpiece lean towards the operator greatly, so that they don't have to spend so much time Bend your body vigorously to clamp the workpiece, so that the operation of the whole processing device is more convenient and reasonable; 3) At the same time, the inclined installation of the workbench is also more conducive to the falling of iron filings, so as to reduce the impact of iron filings on the workpiece. scratches and damages, so as to achieve the purpose of convenient chip removal and improving the yield of workpieces.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

【Description of drawings】

Fig. 2 is the perspective view two of the utility model embodiment.

【Detailed ways】

The utility model relates to a processing device for a large and long roller of a treadmill, comprising a bed 1, an inclined platform 2 inclined to the operator is arranged on the upper part of the bed 1, and a front end of the bed 1 is provided with The headstock 3 and the main shaft motor 5 that drives the main shaft 4 on the headstock 3 to rotate are respectively provided with a sub-spindle seat 7 for installing the sub-spindle 6 and a hydraulic ejector rod on the middle and rear parts below the inclined platform 2. The ejector seat 9 of 8, the sub-spindle 6 and the hydraulic ejector 8 are coaxial with the main shaft 4, and the sub-main shaft 7 and the ejector seat 9 can slide along the Z-axis lower track 10 of the ramp 2; The sub-spindle rotates in the shaft hole 71 of the sub-spindle seat 7, and is controlled by a hydraulic system (not shown in the figure) to clamp the workpiece; a workbench 11 for installing cutting tools is provided in the middle above the inclined table 2 , the workbench 11 includes a lower slide 13 that slides along the Z-axis upper rail 12 of the ramp 2 and an upper slide 14 that slides along the lower slide 13 in the X-axis direction; the upper and lower slides 14, 13 are respectively Driven by the X-axis screw rod 15 and the Z-axis screw rod 16 .

When the utility model is processing the large and long drum of the treadmill, the workpiece to be processed——the drum is first inserted through the sub-spindle 6, and then the ejector rod 9 is pushed to slide forward along the Z-axis lower track 10, so that the hydraulic ejector rod 8 on it is When the workpiece is pressed against the main shaft 4 and clamped between the main shaft 4 and the hydraulic ejector rod 8, the clamping of the workpiece is completed; then, the hydraulic system starts to work to clamp the sub-spindle 7 in the middle of the workpiece; at this time, the main shaft motor 5 Start to work, so that it can drive the workpiece to rotate through the spindle 4 on the head box 3, and make the sub-spindle rotate with the workpiece; next, the workbench 11 starts to work, so the servo motor passes the X and Z axis screw rods respectively 15 and 16 drive the sliding of the upper and lower tables 14 and 13 so that the cutter on the workbench is aligned with one end of the workpiece for processing.

It can be seen from the above that when the utility model uses the sub-spindle 6 to clamp the middle of the workpiece to assist clamping, it uses a hydraulic system to clamp, and the sub-spindle can be followed in the shaft hole 71 of the sub-spindle seat 7. The workpiece rotates together, so that the workpiece will not be pinched, and the wear of the sub-spindle is relatively small, so that the sub-spindle does not need to be maintained frequently. Therefore, the utility model has a reasonable structure and low production and use costs; The main shaft seat 7 and the ejector seat 9 used to install the hydraulic ejector rod 8 are obliquely installed on the inclined table 2 of the oblique operator, so that the workpiece can be greatly leaned against the operator, so that they do not have to bend their body so hard The workpiece is clamped, so that the operation of the whole processing device is more convenient and reasonable; at the same time, the inclined installation of the workbench is also more conducive to the falling of iron filings, so as to reduce the scraping and damage of iron filings on the workpiece, so as to achieve The chip removal is convenient, the purpose of improving the yield of the workpiece, and realizing the high precision, high quality and high efficiency of the product.

In this embodiment, the cutting tool is installed on the workbench through a turret 17 that can rotate 360 degrees on the workbench, so that any tool on the turret can be replaced as required without the need to Frequent disassembly and assembly of tools can improve production efficiency.
