Description

A special drilling and milling machine for auto parts

technical field

The invention belongs to the technical field of tooling for auto parts, and relates to a special drilling and milling machine for auto parts.

Background technique

In the automotive field, the door frame, which is the main part of the car, generally needs milling equipment and special fixtures when milling the holes on it. During the use of the fixtures, the first problem to be faced is the production capacity of the product. Finally, the convenience of picking up parts will affect the production capacity of the product; when the fixture is replaced, the convenience of changing the fixture will affect the processing of the product in the next process, and will also affect the production capacity of the product. One is the existing traditional drilling and milling special machine, the structure of its pick-up device is a vertical ejecting mechanism: the supporting rod is directly installed on the cylinder through the mounting block, and it reciprocates up and down along with the piston rod of the cylinder. The disadvantage of the structure is that the support rod cannot be turned over, which makes it necessary to remove the pick-up device in advance when the fixture on the equipment needs to be replaced, and then the fixture can be replaced. This method not only wastes the operator's time, but also increases the difficulty of the operation At the same time, it affects the mass production capacity of the product; the second is the existing traditional drilling and milling machine, the way of picking up the parts is only the cylinder lifts the product vertically upwards, and then the product is moved along the supporting material through the inclination of the blanking rod itself. The rod slides down. However, in the actual operation process, due to the complexity of the structure of the product itself, the product does not slide down along the drag bar every time, which makes the pick-up mechanism meaningless and not only wastes the time for the operator to pick up the piece manually again , and more importantly, it affects the mass production capacity of the product.

Here, when the compression cylinder 13 drives the right end of the compression member 15 When moving, the compression mask 151 at the left end of the compression member 15 is pressed against the product, thereby facilitating the subsequent precise drilling and milling process.

This patent is mainly used to carry out the drilling and milling process to the automobile door frame products. In order to fix the door frame products, it is necessary to install the fixture 5 on the drilling and milling table 3. The existing mode here is that the supporting rod of the turning and ejecting mechanism 7 is located at On the fixture 5, when producing other products, the fixture 5 needs to be dismantled as a whole after the supporting rod of the flipping and ejecting mechanism 7 is removed. The mold changing process is cumbersome. After pressing, the drilling and milling process can be carried out through the power drilling and milling device 4. After the drilling and milling, it is necessary to automatically pick up the parts. Here, the flipping and ejecting mechanism 7 is used to lift the product upwards when picking up the parts. The horizontal push-out mechanism 8 pushes the product out horizontally to make it in the hopper 9 so as to completely realize the pick-up.

Specifically, there are two main functions of the turning and ejecting mechanism 7, one is to carry out upward ejection, so that the supporting rod has an inclination during the process of lifting the product, and the other function is to facilitate the quick change of the fixture process, as follows Step-by-step description, as shown in Figure 2 and Figure 5, the turning and ejecting mechanism 7 includes a turning support rod 17, a ejecting cylinder 18, a first turning installation plate 19, a second turning installation plate 20 and a hinge pin 21, the first turning An overturning mounting plate 19 is fixed on the output end of the ejection cylinder 18, a second overturning mounting plate 20 is fixed on the first overturning mounting plate 19, there is an overturning space in the second overturning mounting plate 20, and the overturning material rod 17 passes through the hinge pin 21 is hingedly connected to the second overturning mounting plate 20, and the overturning material support rod 17 can be turned upwards in the overturning space to avoid the fixture 5. Here, when the ejection process is realized, the ejection cylinder 18 drives the first overturning installation plate 19 to move upwards, Again because the second overturning mounting plate 20 is fixedly connected with the first overturning mounting plate 19, so just drive the second overturning mounting plate 20 to move upwards, and because the overturning material rod 17 is connected to the second overturning mounting plate 20, so it can Drive the flipping support rod 17 to move upwards, so as to realize the process of lifting the product upwards. The lower side of the second flipping mounting plate 20 is provided with a lower limit block 22. Lean on the lower limit block 22, here through the lower limit block 22, the flipping support rod 17 can be kept in a raised state, thereby supporting the entire product and then pushing upwards. When the fixture 5 needs to be changed, it is mainly completed by the following structure. Due to the flipping A hinged connection block 23 is provided between the support rod 17 and the hinged end of the second overturned mounting plate 20. The hinged connection block 23 includes a hinged fixing portion 231 and an upper overturning limit portion 232. The upper side of the second overturned mounting plate 20 is provided with There is an upper limit block 24, and the upper flip limiter 232 of the flipping support rod 17 is abutted against the upper limit block 24 after being overturned and the flip support rod 17 is opened. Because it is hinged, the flip support rod 17 It can be rotated, so that when the support rod 17 is flipped up and leans against the upper limit block 24, the clamp 5 can be in an open state, and the flip support rod 17 will not interfere with the clamp 5, so that it is convenient and fast to replace , avoiding the fixture 5, the mold can be changed, which will save the operator's time and reduce the difficulty of the operation.

In order to realize automatic pick-up, as shown in Figure 6, the horizontal push-out mechanism 8 here includes a horizontal cylinder 25 and a horizontal support rod 26. The horizontal support rod 26 is connected to the horizontal cylinder 25.
