Description

Shaper

Technical field

The utility model relates to a mechanical processing equipment, in particular to a planer.

Background technique

Existing bull planers, whether they are mechanically or hydraulically driven, plan in one direction, that is, in a reciprocating motion of the ram, only one direction is useful (that is, planing) stroke, and the return stroke is Empty stroke, no planing work. Although the time of idle travel can be shortened by the quick return characteristic of the transmission, it is only an improvement and does not fundamentally solve the problem of low processing efficiency.

Utility model content

The purpose of the utility model is to provide a planer with high processing efficiency.

The purpose of this utility model is achieved in that the utility model comprises a body, a main mechanical transmission system, a ram, a fixed knife rest, a movable knife rest, a planer, a follow-up device, a workbench and an electric control system. The main mechanical transmission system includes a motor, a pinion and a gear, the motor is installed on the body, and the pinion and the gear are installed in the body. There is a ram on the top of the body, and the rack and pinion transmission is formed under the ram through the rack and the large gear in the body. One end of the ram is equipped with a fixed tool holder, and two movable tool holders are installed on the fixed tool holder through the rotating shaft. A planer is respectively installed under each movable knife rest, and the upper ends of the two movable knife rests are fixed by connecting rods so that they become one. Below the planer is the workbench. The follow-up device includes an arm lever, a transition link, a connecting rod and an elastic coupling. The lower end of the arm is hinged with the bottom of the machine body, the upper part of the arm is connected with the large gear through the rocker, the upper end of the arm is connected with one end of the connecting rod through a transition link, the middle part of the connecting rod is installed on the ram through the intermediate shaft, and the connecting rod The other end is hinged with the movable tool holder through an elastic coupling.

Since the utility model is equipped with a follow-up device, the device can control the two planers on the movable tool holder to complete two-way planing in one reciprocating motion of the ram, eliminating idle travel, thereby greatly improving production efficiency.

Detailed ways

See Fig. 1 and Fig. 2, the utility model comprises body 1, main mechanical transmission system, ram 10, fixed knife rest 17, movable knife rest 15 and 20, planer 14 and 22, follow-up device, workbench 24 and electric control system. The main mechanical transmission system includes a motor 5 , a pinion 6 and a bull gear 3 , the motor 5 is installed on the body 1 , and the pinion 6 and the bull gear 3 are installed in the body 1 . The motor 5 and the pinion 6 form a belt transmission, and the pinion 6 and the bull gear 3 form a gear transmission. A ram 10 is installed on the top of the body 1, and the bottom of the ram 10 forms a rack and pinion transmission through the rack 9 and the large gear 3 in the body 1. One end of the ram 10 is equipped with a fixed knife rest 17, and two movable knife rests 15 And 20 are installed on the fixed knife rest 17 by rotating shaft 19, respectively install a planer 14 and 22 below each movable knife rest, and the upper ends of two movable knife rests 15 and 20 are fixed by connecting rod 18 so that they become one. Below the planer 14 and 22 is a workbench 24 on which the workpiece 23 is placed. The follower device includes an arm lever 2 , a transition link 8 , a link 12 and an elastic coupling 13 . The lower end of the arm 2 is hinged with the bottom of the body 1, the upper part of the arm 2 is connected with the large gear 3 through the rocker 7, the upper end of the arm 2 is connected with one end of the connecting rod 12 through the transition link 8, and the middle part of the connecting rod 12 passes through the middle The rotating shaft 11 is installed on the ram 10, and the other end of the connecting rod 12 is hinged with the movable knife rest 15 through the elastic coupling 13.

The working cycle of the utility model includes the planing motion, the displacement follow-up motion of the two planing knives and the lateral feed motion of the workbench.

The planing motion drives the ram 10 to make a reciprocating linear motion through the main mechanical transmission system in the body 1, so that the planer installed on the top of the ram 10 makes a planing motion.

The follow-up movement of the displacement of the two planers is the technical core of the utility model. When the large gear 3 in the body 1 rotates, the rocker 7 on the large gear 3 (connected with the large gear 3 as a rotating pair) drives the arm bar 2 to swing around its lower end; when the ram 10 moves linearly in the forward direction ( That is, moving to the right in Fig. 1), driving the connecting rod 12 connected with it through the intermediate shaft 11 to move in the forward direction (moving to the right in Fig. 1); The speed at which the rotating shaft 11 moves in the forward direction is faster than the speed at which the lower end point of the connecting rod 12 moves in the forward direction. Due to the influence of the speed difference between the upper middle rotating shaft point 11 and the lower end point of the connecting rod 12, under the action of unbalanced force, it will eventually cause The connecting rod 12 will rotate clockwise around the intermediate shaft 11 (take Fig. 1 as an example), and then through the elastic connector 13, the movable tool holders 15 and 20 will rotate clockwise around the shaft 19, and the planer 22 will be turned downward. Enter working position, and planer 14 lifts, leaves working position. In the same way, see Figure 2, when the ram 10 moves in the return direction (moving to the left in Figure 2), the connecting rod 12 will rotate counterclockwise around the intermediate shaft 11 (take Figure 2 as an example), so that, through the elastic The connector 13 rotates the movable tool holders 15 and 20 counterclockwise around the axis of rotation 19, causing the planer 14 to move down into the working position and the planer 22 to lift out of the working position. Therefore, when the ram 10 completes a reciprocating linear motion (that is, two motions of forward and backward), the two planers work alternately (planing) to eliminate idle strokes and improve processing efficiency.

Rotating the handle 16 can control the lifting of the fixed knife rest 17, and by turning the cam 21, the planer in working condition can be kept vertical.
