Description

Technical Field

[0001] The utility model relates to the technical field of CNC machine tool transmission, in particular to a feed transmission tooling of a ram type milling head for a CNC machine tool. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. The milling head is one of the machine tool accessories installed on the milling machine and connected to the spindle to drive the milling cutter to rotate. It is an important part of the machine tool accessories.

[0003] After processing, the milling head is usually transferred in the form of a conveyor belt. Due to the different arrangement orders of the milling heads, it is easy to cause collision and separation when reaching the end of the conveyor belt, which is easy to cause damage to the surface of the milling head. In addition, the existing conveying mechanism cannot transport a single milling head, which will increase the phenomenon of milling head collision and separation.

[0004] Therefore, we designed a feed transmission fixture for a ram-type milling head for CNC machine tools. Utility Model Content

[0005] The utility model aims to solve the problems of collision and separation of the milling head in the prior art and proposes a feed transmission tooling for a ram type milling head used in a numerically controlled machine tool.

[0008] Preferably, a slope is provided on one side of the discharge chute to cushion the fall of the milling head.

[0009] Preferably, a first support plate for supporting a lifting rod is provided on the frame, and the lifting rod is symmetrically arranged at one end of the first support plate.

[0012] Preferably, the adjustment groove is in a slope shape, with a gentle slope at one end, and the adjustment groove is adapted to the bottom of the special-shaped abutment.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model arranges a fixed plate and a special-shaped resisting device so that when the lifting rod drives the milling head to move forward, the position of the first supporting plate on the fixed plate can be changed according to the change of the discharge chute, thereby realizing the function of adjusting the lifting rod backward longitudinally, which can effectively avoid the milling head from colliding with multiple milling heads and causing damage. The special-shaped resisting device can effectively increase the strength of the lifting rod's backward longitudinal adjustment and effectively avoid the lifting rod from rebounding.

[0015] 2. The utility model arranges the adjusting shaft and the adjusting groove so that the special-shaped resist can push the lifting rod under the guidance of the adjusting groove and move synchronously with the lifting rod, which can effectively ensure that the milling head moves from the discharge chute under the guidance of the lifting rod, thereby reducing the phenomenon of the milling head detaching.

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 A feed transmission tooling for a sliding-type milling head for a CNC machine tool includes a frame 1. The frame 1 is a supporting member of a transmission mechanism in the prior art, and the frame 1 only shows a right-angle bend of the transmission mechanism. The right-angle bend of the frame 1 is connected to a milling head processing equipment, and the milling head falls evenly into the front end of the frame 1. A slide groove is opened on the side wall of the frame 1 for arranging a conveyor belt 3. The conveyor belt 3 is a prior art for conveying the milling head. A transmission gear 2 is fixed in the slide groove and driven by an external power supply. The frequency of the external power supply is the same as the discharge frequency of the milling head processing equipment, to ensure that the milling head can fall safely onto a lifting rod 7.

[0022] A discharge chute 8 for guiding the milling head to discharge materials is provided on the frame 1. The discharge chute 8 is provided on one side of the frame 1 and is not in the area where the milling head falls. The discharge chute 8 is mainly used to pull the lifting rod 7 to change the sliding direction, thereby changing the discharge position of the milling head. The discharge chute 8 is connected to the milling head collecting component, and the milling head collecting component is provided with a gentle slope sliding component to facilitate the milling head to slide into the inside. A slope is provided on one side of the discharge chute 8 to cushion the fall of the milling head. The slope is provided on the left side of the discharge chute 8, and is mainly used to cushion the movement of the lifting rod 7 after adjustment, thereby reducing the separation of the milling head from the lifting rod 7 due to vibration.

[0023] A lifting rod 7 for supporting the milling head is provided on the frame 1. The lifting rod 7 is the main load-bearing and transportation component of the milling head. After the milling head falls directly into the load-bearing range of the lifting rod 7, it can enter the discharge trough 8 through the operation of the conveyor belt 3. A first support plate 6 for supporting the lifting rod 7 is provided on the frame 1. The first support plate 6 is used to balance the lifting rod 7 to reduce horizontal instability during movement. The lifting rod 7 is symmetrically arranged at one end of the first support plate 6. There are two lifting rods 7 in total, which can effectively provide a bottom cover for the milling head.

[0024] The conveyor belt 3 is provided with a first connecting plate 4 for guiding the movement of the lifting rod 7. The first connecting plate 4 is the basic component for the synchronous movement of the lifting rod 7 and the conveyor belt 3. One end of the first connecting plate 4 is fixedly connected to the conveyor belt 3 by a fastener, and the fastener can realize the disassembly and replacement function of the first connecting plate 4. The first connecting plate 4 is fixedly connected to the first support plate 6 through a fixed plate 5. The fixed plate 5 is mainly used for the longitudinal adjustment of the first support plate 6 and the function of connecting the first connecting plate 4. A slideway for changing the length of the lifting rod 7 is provided on the fixed plate 5, and the slideway is adapted to the first support plate 6. A slide groove with the same diameter as the slideway is provided in the first support plate 6. When the lifting rod 7 is subjected to thrust, the first support plate 6 can slide on the slideway, thereby changing the range of the lifting rod 7 entering the discharge trough 8.

[0025] A special-shaped resist 12 for limiting the extension length of the lifting rod 7 is provided on the conveyor belt 3. The special-shaped resist 12 is in the shape of a "human" and has a forked end. One end thereof resists against the lifting rod 7, while the other end resists against the side wall of the frame 1, and resists against the adjustment groove 13 according to the transmission distance of the conveyor belt 3. The special-shaped resist 12 is a longitudinal adjustment component of the lifting rod 7. A second support plate 10 for supporting the special-shaped resist 12 is provided on the conveyor belt 3. The second support plate 10 is a horizontal fixing component of the special-shaped resist 12, and the second support plate 10 is fixedly connected to the conveyor belt 3 through a second connecting plate 9. The second connecting plate 9 is a basic component for the synchronous movement of the second support plate 10 and the conveyor belt 3. The special-shaped resist 12 is fixedly connected to the second support plate 10 through a spring shaft 11. The spring shaft 11 is a compression component that can help the special-shaped resist 12 generate thrust.

[0026] The frame 1 is provided with an adjustment groove 13 for extending the special-shaped resist 12. The adjustment groove 13 is a sliding groove for maintaining the current adjustment action after the special-shaped resist 12 is adjusted. The adjustment groove 13 is sloped and has a gentle slope at one end. The adjustment groove 13 is adapted to the bottom of the special-shaped resist 12.

[0027] The working principle of the utility model is as follows: the conveyor belt 3 is driven by the transmission gear 2, so that the lifting rod 7 is located in the milling head falling area under the guidance of the conveyor belt 3, and then the milling head falls on the lifting rod 7, and then enters the discharge trough 8 under the transportation of the conveyor belt 3, and the lifting rod 7 always maintains the current position under the thrust of the special-shaped resisting device 12, and the special-shaped resisting device 12 is under the action of the conveyor belt 3, so that it continuously applies thrust to the lifting rod 7 according to the length of the adjustment groove 13, to ensure that the milling head can safely enter the milling head collecting component.
