Abstract
A broach lifting and feeding device comprises a transitional plate and guide rails. The transitional plate is vertically fixed onto a body of a broaching machine, the guide rails are fixedly vertically disposed on the transitional plate, a ball screw parallel to the guide rails is further arranged on the transitional plate, a nut capable of vertically moving along the ball screw is sleeved on the ball screw, a carriage is fixed onto the nut, matches with the guide rails and is driven by the nut to vertically move along the guide rail, one end of the ball screw is connected with a servo motor by a coupler, the servo motor can drive the ball screw to rotate so as to further drive the nut and the carriage on the nut to move vertically, and a broach lifting device for fixing a broach hilt is fixed on the carriage. The servo motor, the ball screw and the nut match with each other so as to drive the broach lifting device to move along the guide rails vertically, automatic lifting and feeding of a broach can be realized, and the broach lifting device can be adjusted only by means of changing numerical-control programs according to broaches with different lengths.
Description
Technical field
The utility model relates to a kind of knife lifting and delivering device, particularly relates to the knife lifting and delivering device of using on a kind of broaching machine.
Background technology
Vertical broaching machine is a kind of process equipment of Mechanical Manufacturing Enterprises extensive use; In the broaching process for the use of the broaching tool that satisfies different length; Usually utilize the broaching tool guiding mechanism to adjust the height up and down of broaching tool; This broaching tool guiding mechanism adopts the feed screw nut to cooperate and realizes the adjustment of height up and down, and this adjustment process adopts manual mode usually, and labour intensity is big.And submitting by hydraulic drive mechanism of broaching tool accomplish, and realize the adjustment of broaching tool height and submit, and two mechanisms just need be set to realize respectively, and therefore, complex structure, assembling is difficult, manufacturing cost is high.
Summary of the invention
The utility model technical problem to be solved provide a kind of simple in structure, be easy to assemble, the knife lifting and delivering device of low cost of manufacture.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of knife lifting and delivering device; Comprise the rebound that vertically is fixed on the broaching machine lathe bed; And be fixed on the rebound guide rail that is provided with up and down; Also be provided with the ball screw parallel on the said rebound, be with the nut that can move up and down along this ball screw on the said ball screw, be fixed with slide carriage on the said nut with guide rail; And said slide carriage matches with guide rail, and guide rail moves up and down in the drive lower edge of nut; One end of said ball screw is connected with servomotor through shaft coupling, and said servomotor can drive that ball screw rotates and then drive nut and move up and down with slide carriage on it, is fixed with the device of griffing of fixing broaching tool shank on the said slide carriage.This knife lifting and delivering device utilizes servomotor and ball screw nut to match to drive griffes device and moves up and down along guide rail; Not only can realize the automatic knife lifting and delivering of broaching tool, and only need change numerical control program to the broaching tool of different length can be to griffing device adjustment.
For the stationarity that guarantees that slide carriage moves up and down, said guide rail is two, and lays respectively at the ball screw both sides, matches with said two guide rails respectively in the both sides of said slide carriage.
Preferably, the top chock and the step at two ends are fixed on the rebound said ball screw up and down through it.
Compared with prior art; The advantage of the utility model is that this knife lifting and delivering device utilizes servomotor and ball screw nut to match to drive and griffes device and move up and down along guide rail; Not only can realize the automatic knife lifting and delivering of broaching tool, and only need change numerical control program to the broaching tool of different length can be to griffing device adjustment, not only simple in structure, be easy to assembling, low cost of manufacture; And reduced labour intensity, improved the production efficiency of broaching machine.
Description of drawings
Fig. 1 is the front schematic view (part is analysed and observe) of the utility model knife lifting and delivering device.
Fig. 2 is the side schematic view (part is analysed and observe) of the utility model knife lifting and delivering device.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-2, the knife lifting and delivering device of the utility model comprises servomotor 1, shaft coupling 2, ball screw 3, nut 4, slide carriage 5, guide rail 6, rebound 7, griffe device 8, top chock 9 and step 10.Said rebound 7 is arranged on up and down on the lathe bed of broaching machine vertically, and rebound 7 is provided with guide rail 6, and said guide rail 6 is at least one, and is as shown in Figure 1, preferably, and be provided with for parallel vertical side by side two.The ball screw 3 that laterally arranges with guide rail 6 also is housed on the rebound 7, and this ball screw 3 is positioned in the middle of two guide rails 6, and said ball screw 3 is through the top chock 9 and the step 10 at two ends are fixed on the rebound 7 up and down.Be with nut 4 on the said ball screw 3, thereby said nut 4 can move up and down along the screw thread on the ball screw 3 with respect to ball screw 3.Being fixed with slide carriage 5 on this nut 4, matches with guide rail 6 in the both sides of this slide carriage 5, so this slide carriage 5 can move up and down by guide rail 6 in the drive lower edge of nut 4, be installed with on this slide carriage 5 fixing broaching tool shank griffe device 8.Servomotor 1 is connected with an end of ball screw 3 through shaft coupling 2; Driving ball screw 3 motion drive nuts 4 and slide carriage 4 moves up and down; And then make this griffe device 8 to move up and down along guide rail 6, accomplish submitting of broaching tool, when using the different broaching tool of length; Only need the adjustment of change numerical control program to griffe the range of movement and the position of device, just can realize this and griffe the adjustment of device.
Therefore this knife lifting and delivering device utilizes the drive that matches of servomotor and ball screw nut to griffe device and move up and down along guide rail; Not only can realize the automatic knife lifting and delivering of broaching tool; And only need change numerical control program to the broaching tool of different length can be to griffing device adjustment; Not only simple in structure, be easy to assembling, low cost of manufacture, and labour intensity is also low, has improved the production efficiency of broaching machine.
Except that the foregoing description, the utility model also includes other embodiments, and the technical scheme that all employing equivalents or equivalent substitute mode form all should fall within the protection domain of the utility model claim.
