Description

Technical Field

[0001] The utility model relates to the technical field of machine tool turntables, in particular to a five-axis machine tool turntable with a shock-absorbing structure. Background Art

[0002] The machine tool turntable is generally driven by a servo motor. The power is transmitted through the transmission structure of the mechanical system (pulley, turbine, worm, etc.) to drive the worktable to rotate, and the worktable on it is used to fix the processed parts.

[0003] When existing machine tools are in operation, the parts will inevitably vibrate as the cutting progresses, and then the vibration is transmitted to the workbench. However, the vibration of the workbench will more or less affect the processing accuracy of the parts, and thus affect the processing quality. Even if some machine tool turntables adopt high-strength connection structures, they will gradually wear out as the use time increases. Therefore, we proposed a five-axis machine tool turntable with a shock-absorbing structure. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0009] In a preferred example, the present invention can be further configured as follows: the retaining mechanism includes an electric telescopic rod fixed to both ends of the support plate, a connecting plate fixed to the driving end of the electric telescopic rod and attached to the outside of the rotating shaft, and a baffle vertically fixed to the connecting plate.

[0010] In a preferred example, the present invention can be further configured as follows: a slot for the card block to be mounted is provided on the support plate, and a buffer pad is fixed to the end of the card block.

[0011] In a preferred example, the present invention can be further configured as follows: a sealing sleeve is connected between the support plate and the hydraulic rod.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] 1. The utility model uses a shock-absorbing component to utilize a hydraulic pump to provide hydraulic power to the hydraulic rod, thereby supporting the support plate to lift and reinforce the rotating shaft, thereby improving the shock-absorbing effect of the rotating shaft. In addition, the setting of the support plate does not affect the rotation operation of the rotating shaft, and the practicality is high.

[0014] 2. The utility model uses a shock-absorbing component and can use an electric telescopic rod to drive the connecting plate to extend and retract, thereby moving the baffle to the side of the fixed table.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] A five-axis machine tool turntable with a shock-absorbing structure provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] Combine Figure 1-3 As shown, the utility model provides a five-axis machine tool turntable with a shock-absorbing structure, comprising: a turntable assembly 100 and a shock-absorbing assembly 200 installed on the turntable assembly 100;

[0026] Among them, the shock absorbing assembly 200 includes a driving mechanism installed at the bottom of the turntable assembly 100, a shock absorbing mechanism connected to both sides of the driving mechanism and a retaining mechanism arranged on the shock absorbing mechanism; the shock absorbing mechanism includes a fixed rail 210 embedded in the turntable assembly 100, a block 220 clamped in the fixed rail 210, a support plate 230 connected to the outer end of the block 220, a piston rod 240 fixed to the bottom of the support plate 230 and a hydraulic rod 250 sleeved on the outside of the piston rod 240. Through the shock absorbing assembly 200, the hydraulic pump 260 can be used to provide hydraulic power to the hydraulic rod 250, thereby supporting the support plate 230 to support and reinforce the rotating shaft 120, thereby improving the shock absorbing effect of the rotating shaft 120, and the setting of the support plate 230 does not affect the rotation operation of the rotating shaft 120, and is highly practical.

[0027] Furthermore, the turntable assembly 100 includes a base 110 , a rotating shaft 120 assembled in the middle of the base 110 , and a fixing platform 130 installed on the rotating shaft 120 .

[0028] Specifically, the driving mechanism includes a hydraulic pump 260 installed in the middle of the pedestal 110, a hydraulic pipe 270 connected between the hydraulic pump 260 and the hydraulic rod 250, and a vibration sensor 280 installed on the rotating shaft 120. The vibration sensor 280 can be used to monitor the vibration amplitude of the rotating shaft 120, and then the hydraulic pump 260 increases or decreases the oil pressure in the hydraulic rod 250 through the hydraulic pipe 270, thereby improving the stability of the rotating shaft 120.

[0029] Furthermore, the retaining mechanism includes an electric telescopic rod 310 fixed to both ends of the support plate 230, a connecting plate 320 fixed to the driving end of the electric telescopic rod 310 and attached to the outside of the rotating shaft 120, and a baffle 330 vertically fixed on the connecting plate 320. The electric telescopic rod 310 can be used to drive the connecting plate 320 to extend and retract, thereby causing the baffle 330 to move to the side position of the fixed platform 130. In this way, cutting fluid can be retained around the fixed platform 130, and the liquid can be used to absorb vibration energy and then overflow and slide down, thereby further improving the shock absorption effect of the turntable.

[0030] On the other hand, a card slot 231 for the card block 220 to be mounted is provided on the support plate 230, and a buffer pad 232 is fixed to the end of the card block 220. The buffer pad 232 can play a buffering role when the card block 220 is subjected to vibration, thereby preventing the card block 220 from being hard damaged, and does not affect the normal use of the card block 220.

[0031] Furthermore, a sealing sleeve 233 is connected between the support plate 230 and the hydraulic rod 250 , and the sealing sleeve 233 can seal the end of the hydraulic rod 250 to prevent the cutting fluid from contacting the piston rod 240 .

[0032] The working principle and usage process of the present invention are as follows: first, the part to be processed is fixed on the fixed table 130, and the driving part in the rear base 110 drives the rotating shaft 120 to rotate. At the same time, the driving part in the rotating shaft 120 can drive the fixed table 130 to rotate, and the angle of the part is adjusted in many aspects. When the vibration sensor 280 detects that the vibration of the rotating shaft 120 exceeds the preset range, the hydraulic pump 260 provides hydraulic power to the hydraulic rod 250, and then supports the support plate 230 to support and reinforce the rotating shaft 120, thereby improving the shock absorption effect of the rotating shaft 120. At the same time, the extension of the connecting plate 320 can be controlled by the electric telescopic rod 310, so that the baffle 330 is blocked on the side of the fixed table 130, thereby retaining the cutting fluid around the fixed table 130, using the liquid to absorb the vibration energy, and then overflowing and sliding down.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
