Description

Profiling trimming device

Technical Field

The invention relates to the technical field of plate processing, in particular to a profiling trimming device.

Background

The profiling deburring device may also be referred to as a tracking deburring device. In the technical field of plate processing, after an edge banding machine connects an edge banding to a plate, the right-angled edge of the edge banding is required to be cut into an arc angle through a profiling trimming device.

In large-scale plate edge sealing production, edge sealing belts with different thicknesses are required to be trimmed. Therefore, it is necessary to adjust the position of the deburring cutter of the copying deburring device. The position of the trimming cutter is generally manually adjusted at present, and the adjusting efficiency is low. Accordingly, there has been proposed a copying and deburring apparatus having a pneumatic adjustment mechanism capable of rapidly driving a deburring tool forward or backward to adjust the position of the deburring tool. However, the adjustment accuracy is low, thereby reducing the yield of the sheet material profiling trimming.

Therefore, it is necessary to provide a copying and deburring device with high positional accuracy of the deburring tool.

Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

Fig. 1 is an overall configuration diagram of a copying/trimming apparatus 100 according to an embodiment of the present invention. FIG. 2 is a perspective view of a copying and trimming device 100 in accordance with an embodiment of the present invention. For convenience of description, the present application takes the X direction as the front and the opposite direction as the back in the drawings. The front is consistent with the transverse direction and the rear.

As shown in fig. 1 and 2, the present embodiment discloses a profiling deburring device 100, wherein the profiling deburring device 100 comprises a fixed base 10, a first power mechanism 51, a movable base 20, a lateral guide wheel 31, a second power mechanism 52, a cutter assembly 40 and a limit assembly. The movable seat 20 is transversely slidably disposed on the fixed seat 10 and is driven by the first power mechanism 51 to slide back and forth. The lateral guide wheel 31 is fixedly mounted to the movable base 20. The cutter assembly 40 is transversely slidably disposed on the movable base 20 and is driven by the second power mechanism 52 to slide back and forth. The cutter assembly 40 includes a cutter 41 and a motor 42 driving the cutter 41 to cut the sheet material 200. The cutter 41 is mounted on an output shaft of the motor 42. The position of the fixed seat 10 is fixed, and the fixed seat 10 can be installed on a frame of the edge bonding machine through the installation frame 11.

The first power mechanism 51 may be a cylinder, which is installed on the movable seat 20, and a piston rod of the cylinder is connected to the fixed seat 10. Because fixing base 10 is fixed, the fixing base 10 is located to sliding 20 transversely, consequently, the piston rod of cylinder stretches out, can drive sliding 20 and transversely move backward, and the piston rod shrink of cylinder can drive sliding 20 and transversely move forward. Since the lateral guide wheel 31 and the cutter assembly 40 are both mounted on the movable base 20, the lateral guide wheel 31 and the cutter assembly 40 can move laterally rearward or laterally forward with the movable base 20. Lateral guide wheel 31, and thus knife assembly 40, can be laterally rearward away from sheet material 200 and laterally forward toward sheet material 200.

The lateral guide wheels 31 serve to guide the lateral sides of the sheet 200. As shown in fig. 1, the present embodiment preferably further includes a bottom guide wheel 32 mounted to the movable base 20, wherein the bottom guide wheel 32 is used for guiding the bottom surface of the plate material 200.

As shown in fig. 2, the second power mechanism 52 may be an air cylinder, which is mounted on the movable base 20, and a piston rod of the air cylinder is connected to the cutter assembly 40. Since the cutter unit 40 is laterally slidably provided on the movable base 20, the cutter unit 40 can move forward when the piston rod of the air cylinder is contracted, and the cutter unit 40 can move backward when the piston rod of the air cylinder is extended. I.e. the cutter assembly 40 is driven forward or backward with respect to the lateral guide wheel 31 by the second power mechanism 52.

Specifically, as shown in fig. 1 and 2, the cutter assembly 40 further includes a motor mounting block 43, a bearing seat 44, an optical axis 45, a first connecting block 46, a connecting rod 47, and a second connecting block 48, and the motor 42 is mounted to the motor mounting block 43. The motor mounting block 43 is mounted to the bearing housing 44. The bearing housing 44 is connected to the outer end of the piston rod of the second power mechanism 52 through the first connection block 46, the connection rod 47, and the second connection block 48 in order. The bearing holder 44 is mounted on the optical axis 45 and can move back and forth along the optical axis 45 by means of a linear bearing. The second power mechanism 52 can drive the bearing seat 44 to move back and forth relative to the lateral guide wheel 31, and further drive the motor 42 to move back and forth relative to the lateral guide wheel 31, so as to drive the cutter 41 to move back and forth relative to the lateral guide wheel 31.

FIG. 3 is a comparison of the positional relationship between the cutter 41 and the lateral guide wheel 31 when the profiling trimming device 100 of the embodiment of the present invention is replacing the banding strips 300 of different thicknesses.

For example, when the thickness of the edge sealing tape 300 is changed from h to 2h, the side guide wheel 31 is always in close contact with the side surface of the plate material 200 by the first power mechanism 51, and therefore, the cutter 41 needs to be moved forward h relative to the side guide wheel 31. At this time, in order to ensure the positional accuracy of the forward movement h of the cutter 41, the front stopper assembly 60a is required to stop the cutter 41. The specific structure of the front check assembly 60a will be described below.

For example, when the thickness of the edge sealing tape 300 is changed from 2h to h, the side guide wheel 31 is always in close contact with the side surface of the plate material 200 by the first power mechanism 51, and therefore, the cutter 41 needs to be moved backward h with respect to the side guide wheel 31. At this time, in order to ensure the positional accuracy of the backward movement h of the cutter 41, the rear stopper assembly 60b is required to stop the cutter 41. The structure of the rear check assembly 60b will be described below.

When the existing edge banding strips 300 with different thicknesses are replaced, the position precision of the adjusting cutter is low. In the present embodiment, in order to improve the position accuracy of the adjustment tool 41, the following measures are adopted:

the contouring trimming apparatus 100 also includes a stop assembly that is divided into a front stop assembly 60a and a rear stop assembly 60 b. The present embodiment may only include the front limiting assembly 60a, or only include the rear limiting assembly 60 b. Preferably, the present embodiment includes both a front stop assembly 60a and a rear stop assembly 60 b. Generally speaking, the limiting component comprises a support fixedly installed on the movable seat 20, a rotating shaft installed on the support and capable of moving transversely through self rotation, and a counter connected with the rotating shaft and rotating synchronously with the rotating shaft. The shaft has a limiting portion that limits the cutter assembly 40 in a transverse forward or backward direction.

The profiling trimming device 100 of the present invention has the following advantageous effects: when the edge sealing strips 300 with different thicknesses are replaced, the rotating shaft is rotated and the limiting part is transversely adjusted to a preset position by combining the display numerical value of the counter. Then, the second power mechanism 52 drives the cutter 41 assembly to move transversely until the cutter assembly is limited by the limiting part, and the position adjustment of the cutter assembly 40 is completed. As described above, the copying/trimming apparatus 100 according to the present invention can improve the accuracy of adjusting the position of the cutter unit 40 when the selvage edges 300 having different thicknesses are switched.

Fig. 4 is a cross-sectional view of a front limiting assembly 60a according to an embodiment of the present invention. As shown in fig. 4, the specific structure of the front limiting component 60a is as follows:

the front limit assembly 60a includes a support 61a fixedly installed on the movable base 20, a rotating shaft 62a installed on the support 61a and capable of moving back and forth in a transverse direction by rotating itself, and a counter 63a connected to the rotating shaft 62a and rotating synchronously with the rotating shaft 62 a. The rotating shaft 62a has a limiting portion 621a, and the limiting portion 621a limits the cutter assembly 40 in the transverse forward direction.

Specifically, the rotating shaft 62a has an external thread, the seat 61a has an internal threaded hole therein, and the rotating shaft 62a is threadedly engaged with the seat 61 a. The rotation of the shaft 62a enables a forward and backward movement with respect to the support 61a, i.e. with respect to the mobile platform 20, i.e. with respect to the lateral guide wheel 31. The rotation shaft 62a moves forward and backward to adjust the stopper 621a to a predetermined position.

During the rotation of the rotating shaft 62a, the counter 63a can display the position of the rotating shaft 62a moving back and forth, so that the limiting portion 621a can be accurately located at the predetermined position, and finally the cutter assembly 40 can be accurately located at the predetermined position.

Preferably, the front limit component 60a further includes a shaft sleeve 64a and a limit plate 65a, and the shaft sleeve 64a is sleeved on the rotating shaft 62a and rotates synchronously with the rotating shaft 62 a. The limit plate 65a is connected with the support 61a and limits the shaft sleeve 64a in the transversely opposite direction, so that the shaft sleeve 64a can only rotate and cannot move back and forth. The sleeve of the counter 63a is connected to the sleeve 64 a. The arrangement of the bushing 64a has the advantages that: the installation of the counter 63a is facilitated.

Specifically, the rotating shaft 62a is disposed laterally, and the counter 63a, the stopper plate 65a, and the holder 61a are arranged in this order from the rear to the front. The rear end of the rotating shaft 62a extends out of the sleeve 64a and the counter 63a, and the rear end of the rotating shaft 62a forms an operating end 623a, and the end surface of the operating end 623a is polygonal, so that an operator can conveniently rotate the rotating shaft 62 a.

Preferably, the front end surface 641a of the boss 64a is retained by the holder 61a, and the outer surface of the front end of the boss 64a has a flange 642a, and the flange 642a is retained by the retaining plate 65a in the rearward direction. The limiting structure of the shaft sleeve 64a is simple.

Preferably, the position-limiting plate 65a has a through hole and is disposed on the shaft sleeve 64a, the hole wall of the through hole is configured with a position-limiting surface 651a, and the position-limiting surface 651a limits the flange 642a, so that the shaft sleeve 64a cannot move backwards. The stopper plate 65a of the present embodiment has a simple structure.

Preferably, the sleeve of the counter 63a has a through hole and is fitted over the sleeve 64 a. The sleeve of the counter 63a is connected with the sleeve 64a through a connecting piece so as to rotate synchronously.

Preferably, the rotating shaft 62a is provided with a first mounting hole 622a extending laterally, and the bushing 64a is provided with a second mounting hole. The pin 66a sequentially passes through the second mounting hole and the first mounting hole 622a in the longitudinal direction and is transversely slidably disposed in the first mounting hole 622a, so that the shaft sleeve 64a and the rotating shaft 62a rotate synchronously, and the rotating shaft 62a can move transversely back and forth.

Preferably, the front limiting assembly 60a further includes a locking block 67a, and the locking block 67a is disposed on the rotating shaft 62a adjacent to the support 61a and is in threaded engagement with the rotating shaft 62 a. The rotation shaft 62a can be locked by the locking block 67a, so that the limiting portion 621a is reliably located at a predetermined position, and the position of the limiting portion is not changed in the process of cutting the plate 200 by the cutter 41. Specifically, the locking block 67a is located on the front side of the seat 61 a.

Preferably, the front limiting assembly 60a further includes a locking nut 68a extending transversely, and the locking nut 68a connects the locking block 67a and the support 61a, so as to facilitate eliminating a thread gap between the rotating shaft 62a and the support 61a, thereby further improving the forward and backward movement precision of the rotating shaft 62a and achieving the effect of further improving the position precision of the adjusting tool 41.

Preferably, the stopper 621a is formed at the front end of the rotation shaft 62 a. The front limit component 60a further includes a sliding block 69a slidably disposed on the rotating shaft 62a and limited by the limit portion 621a in the forward direction, and the sliding block 69a is connected to the cutter component 40. Specifically, as shown in fig. 2, the slide block 69a is connected to the bearing housing 44. The stopper 621a restricts the position of the cutter 41 by restricting the slide block 69 a.

As shown in fig. 2, the rear limiting unit 60b is spaced apart from the front limiting unit 60 a. Fig. 5 is a cross-sectional view of a rear limiting assembly 60b in accordance with an embodiment of the present invention. As shown in fig. 5, the specific structure of the rear limiting unit 60b is as follows:

the rear limiting assembly 60b has substantially the same principle and structure as the front limiting assembly 60a, and like the front limiting assembly 60a, the rear limiting assembly 60b also includes a support 61b, a rotating shaft 62b, a limiting portion 621b, a first mounting hole 622b, an operating end 623b, a counter 63b, a shaft sleeve 64b, a front end surface 641b, a flange 642b, a limiting plate 65b, a limiting surface 651b, a pin 66b, a locking block 67b, and a locking nut 68 b. The positions and connection relationships among the holder 61b, the rotating shaft 62b, the stopper 621b, the first mounting hole 622b, the operating end 623b, the counter 63b, the boss 64b, the front end face 641b, the flange 642b, the stopper plate 65b, the stopper face 651b, the pin 66b, the lock block 67b, and the lock nut 68b are also identical to those of the front stopper assembly 60 a.

The rear limiting assembly 60b is different from the front limiting assembly 60a in that: 1. the limiting portion 621b of the rear limiting assembly 60b is different from the limiting portion 621a of the front limiting assembly 60a, and the rear limiting assembly 60b does not include a sliding block. 2. The support 61b is of unitary construction with the movable seat 20.

The limiting portion 621b of the rear limiting component 60b is an end surface of the front end of the rotating shaft 62b, and the limiting portion 621b limits the cutter component 40 in the backward direction.

When the cutter assembly 40 needs to move backward, it is directly limited by the front end surface of the rotating shaft 62b (i.e., the limiting portion 621b) when moving backward to a predetermined position.

In the invention, under the condition that the limiting part 621a is accurately adjusted to the preset position and the limiting part 621b is accurately adjusted to the preset position, the position of the cutter 41 can be quickly switched by the second power mechanism 52 so as to quickly adapt to the edge sealing belt 300 with new thickness.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
