Description

Technical Field

[0001] The invention relates to the technical field of semitrailer rod cutting, in particular to a cutting device for semitrailer manufacturing. Background Art

[0002] A semitrailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. A semitrailer is generally a three-axle semitrailer, and is divided into many types such as 11-meter warehouse rail semitrailer, 13-meter warehouse rail, low-bed semitrailer, etc. It is a heavy-duty transport vehicle connected to the semitrailer head by a traction pin. When manufacturing the semitrailer, the rods for manufacturing the warehouse rail need to be cut.

[0003] The existing rod cutting device of the semi-trailer cargo rail needs to use two or more sets of clamping devices to firmly clamp the rod when cutting the rod. When cutting the rod, the clamping devices need to be separated first, and then the rod is placed between the clamping devices, and then the clamping devices are assembled to clamp the rod before cutting. After the cutting is completed, the clamping devices still need to be manually separated before the cut rod can be manually removed, which is a cumbersome operation during cutting. Summary of the invention

[0004] In view of this, the present invention provides a cutting device for manufacturing a semitrailer to solve the problem that the existing rod cutting device for the semitrailer bar needs to frequently manually operate the clamping device during cutting, which makes the operation complicated.

[0005] The present invention provides a cutting device for manufacturing a semi-trailer, which specifically comprises: a bottom plate; a side baffle is fixedly arranged on the left side of the top of the bottom plate by welding; two electric cylinders are fixedly arranged on the front side of the top of the bottom plate; a length measuring plate is fixedly installed on the top of the two electric cylinders; a first support block is fixedly arranged on the right side of the top of the bottom plate; a second support block is also fixedly arranged on the left side of the top of the bottom plate; a third support block is slidably installed at the middle position of the top of the bottom plate; an auxiliary support block is rotatably installed on the left side of the second support block and the third support block; a push block support frame is fixedly connected to the front side of the second support block and the third support block; a push block support rod is slidably installed on the push block support frame; a material unloading push block is fixedly arranged at the rear end of the push block support rod; a support sleeve is slidably installed on the outer side of the length measuring plate; a push rod is fixedly arranged on the top of the support sleeve and the top of the length measuring plate; a motor is fixedly installed on the top of the rear side of the support sleeve; and a cutting wheel is fixedly arranged on the right side of the main shaft of the motor.

[0006] Further, the support sleeve can slide left and right on the outside of the length measuring plate. The top of the length measuring plate is provided with scale lines that increase sequentially from left to right. The left side surface of the length measuring plate and the right side surface of the side baffle are in the same vertical plane. The right side surface of the top of the support sleeve and the left side surface of the cutting wheel are in the same vertical plane. Moreover, a knob is screwed to the right side of the top of the support sleeve.

[0007] Further, a guide rail is provided on the top of the bottom plate. A corresponding guide groove is provided at the bottom of the third support block. A round rod is provided at the rear of the support sleeve. A vertically penetrating vertical groove with a width equal to the diameter of this round rod is also provided in the lower part of the third support block. The round rod at the rear of the support sleeve can slide up and down in this vertical groove.

[0008] Further, a circular hole is provided in the middle of each of the first support block, the second support block, the third support block, and the auxiliary support block. The inner diameter of the circular hole is equal to the outer diameter of the rod to be cut. Moreover, an opening with a width equal to the inner diameter of the circular hole in the middle is provided on one side of each of the second support block, the third support block, and the auxiliary support block.

[0009] Further, a spring is provided on the outside of each of the push block support rods. The spring can push the blanking push block and the push block support rod to slide backward under the support of the push block support frame.

[0010] Further, twelve protruding teeth are provided at the upper rear position of the rear side of the push rod. Twelve corresponding tooth grooves are provided on the outside of each of the auxiliary support blocks. These twelve tooth grooves account for one-fourth of the outer circumference of the auxiliary support block.

[0011] Further, the rear side of each of the blanking push blocks is a wedge-shaped block structure. When the blanking push block slides to the rearmost side, the rear right side of it will be in front of the foremost position of the circular holes in the middle of the first support block, the second support block, the third support block, and the auxiliary support block.

[0012] Further, the openings on the outside of the second support block and the third support block both face backward. When the push rod moves down to the lowest point, the opening on the outside of the auxiliary support block faces upward. When the push rod moves up to the highest point, the opening on the outside of the auxiliary support block also faces backward.

[0013] Beneficial effects

[0014] 1. In the present invention, the second support block, the third support block and the auxiliary support block cooperate to support and fix the part of the rod to be cut. Before cutting, the opening on the outside of the auxiliary support block faces upward, so that the rod can be prevented from detaching from these support blocks. When cutting, the length measuring plate needs to drive the motor and the cutting wheel to move upward. At the same time, the two push rods also move upward. When the push rods move upward, they can drive the auxiliary support block to rotate, and finally the opening on its outside also faces backward. Therefore, the blanking push block can push the cut rod backward to make it detach from the second support block, the third support block and the auxiliary support block, and there is no need to manually remove the cut rod, making the operation more convenient when cutting the rod.

[0015] 2. The rear sides of the blanking push blocks in the present invention are all wedge-shaped block structures. When the rod needs to be cut, first pass the left end of the rod through the round holes in the middle of the first support block, the third support block and the second support block in sequence and press it against the right side of the side baffle. In this process, the left end of the rod will first contact the inclined surface on the rear side of the blanking push block, so that the blanking push block and the push block support rod can be automatically pushed forward to slide. When fixing the rod, there is no need to manually pull the blanking push block and the push block support rod forward, so the operation is also very convenient when fixing the rod.

[0028] In order to make the purpose, scheme and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention.

[0029] Example: Please refer to Figures 1 to 8 As shown:

[0030] The present invention provides a cutting device for semi-trailer manufacturing, including a bottom plate 1; a side baffle 2 is fixedly arranged on the left side of the top of the bottom plate 1 by welding. The bottom plate 1 is used to support the upper part structure of the device, and the side baffle 2 is used to position the left end of the rod to be cut; two electric cylinders 3 are fixedly arranged on the front side of the top of the bottom plate 1. The electric cylinders 3 are used to adjust the up and down position of the length measuring plate 4. During use, the length measuring plate 4 is pushed upward by the electric cylinders 3. Thus, the motor 14 behind the support sleeve 13 and the cutting wheel 15 can be synchronously lifted to cut the rod. At the same time, the two push rods 9 can also be synchronously lifted, so that the two auxiliary support blocks 8 rotate to make the openings on their outer sides face backward. Then, after the rod is cut, it can be automatically released and pushed backward; a length measuring plate 4 is fixedly installed on the top of the two electric cylinders 3. The length measuring plate 4 is used to slidably support the support sleeve 13. Moreover, the support sleeve 13 and the scale on the top of the length measuring plate 4 can be used to adjust the distance between the cutting wheel 15 and the side baffle 2. Thus, rods of different lengths can be cut; a first support block 5 is fixedly arranged on the right side of the top of the bottom plate 1. The first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8 cooperate together to support and position the rod to be cut, avoiding the rod from shaking during cutting; a second support block 6 is also fixedly arranged on the left side of the top of the bottom plate 1. The first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8 cooperate together to support and position the rod to be cut, avoiding the rod from shaking during cutting; the openings on the outer sides of the second support block 6 and the third support block 7 both face backward. When the push rod 9 moves down to the lowest point, the opening on the outer side of the auxiliary support block 8 faces upward. When the push rod 9 moves up to the highest point, the opening on the outer side of the auxiliary support block 8 also faces backward. Before cutting the rod, the push rod 9 is at the lowest point. At this time, the opening on the outer side of the auxiliary support block 8 faces upward. Therefore, the auxiliary support block 8 can cooperate with the second support block 6 and the third support block 7 to fix the rod in the circular hole in the middle. During the process of cutting the rod, the push rod 9 moves up to drive the auxiliary support block 8 to rotate. After cutting is completed, the opening on the outer side of the auxiliary support block 8 faces backward. Thus, the cut rod can be released; a third support block 7 is slidably installed at the middle position of the top of the bottom plate 1. The first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8 cooperate together to support and position the rod to be cut, avoiding the rod from shaking during cutting; an auxiliary support block 8 is rotatably installed on the left side of each of the second support block 6 and the third support block 7. Before cutting the rod, the push rod 9 is at the lowest point. At this time, the opening on the outer side of the auxiliary support block 8 faces upward. Therefore, the auxiliary support block 8 can cooperate with the second support block 6 and the third support block 7 to fix the rod in the circular hole in the middle. During the process of cutting the rod, the push rod 9 moves up to drive the auxiliary support block 8 to rotate. After cutting is completed, the opening on the outer side of the auxiliary support block 8 faces backward. Thus, the cut rod can be released;A push block support frame 10 is fixedly connected to the front side of both the second support block 6 and the third support block 7. The push block support frame 10 is used for slidingly supporting the push block support rod 11 and the blanking push block 12. A push block support rod 11 is slidably installed on each of the push block support frames 10. The push block support rod 11 is used for supporting the blanking push block 12. A blanking push block 12 is fixedly provided at the rear end of each of the push block support rods 11. When the rod needs to be cut, the left end of the rod is first passed through the round holes in the middle of the first support block 5, the third support block 7, and the second support block 6 in sequence and closely abuts against the right side surface of the side baffle 2. During this process, the left end of the rod will first contact the inclined surface at the rear side of the blanking push block 12. Therefore, the blanking push block 12 and the push block support rod 11 can be pushed to slide forward. When the rod cutting is completed, the opening on the outside of the auxiliary support block 8 will face the rear side. At this time, the spring on the outside of the push block support rod 11 can push the blanking push block 12 to quickly move backward. Therefore, the cut rod can be pushed backward to disengage from the second support block 6, the third support block 7, and the auxiliary support block 8, without manually removing the cut rod. A support sleeve 13 is slidably installed on the outside of the length measuring plate 4. The support sleeve 13 is used for supporting the motor 14 and the cutting wheel 15. A push rod 9 is fixedly provided at the top of both the support sleeve 13 and the length measuring plate 4. When the push rod 9 moves up and down, it can drive the auxiliary support block 8 to rotate through the engagement of the convex teeth on its rear side with the tooth grooves on the outside of the auxiliary support block 8, so as to change the orientation of the opening on the outside of the auxiliary support block 8. A motor 14 is fixedly installed at the top rear side of the support sleeve 13. The motor 14 is used for driving the cutting wheel 15 to rotate. A cutting wheel 15 is fixedly provided on the right side of the main shaft of the motor 14. The cutting wheel 15 is used for cutting the rod.

[0031] Among them, the support sleeve 13 can slide left and right on the outside of the length measuring plate 4. Scale lines that increase sequentially from left to right are provided on the top of the length measuring plate 4. The left side surface of the length measuring plate 4 and the right side surface of the side baffle 2 are located in the same vertical plane. The right side surface of the top of the support sleeve 13 and the left side surface of the cutting wheel 15 are located in the same vertical plane. And a knob is screwed on the top right side of the support sleeve 13. When using this device to cut a rod, make the left end of the rod closely abut against the right side surface of the side baffle 2, and then the position of the support sleeve 13 can be adjusted by sliding left and right. The cooperation between the support sleeve 13 and the scale on the top of the length measuring plate 4 can adjust the distance between the cutting wheel 15 and the side baffle 2. After the adjustment is completed, tighten the knob on the top right side of the support sleeve 13 to fix the position, and then rods of different lengths can be cut.

[0032] Among them, a guide rail is arranged on the top of the bottom plate 1, a corresponding guide groove is arranged at the bottom of the third support block 7, a round rod is arranged at the rear side of the support sleeve 13, and a vertical groove running through from front to back with a width equal to the diameter of this round rod is also arranged in the lower part of the third support block 7. The round rod at the rear side of the support sleeve 13 can slide up and down in this vertical groove. Therefore, when the support sleeve 13 is slid left and right for adjustment, the third support block 7 will be driven to slide left and right synchronously through the round rod at its rear side, which is convenient for stably supporting the rod to be cut, and it will not affect the normal up and down movement of the length measuring plate 4 driving the support sleeve 13.

[0033] Among them, a round hole is arranged in the middle of each of the first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8. The inner diameter of the round hole is equal to the outer diameter of the rod to be cut, and an opening with a width equal to the inner diameter of the round hole in the middle is arranged on one side of each of the second support block 6, the third support block 7 and the auxiliary support block 8. When cutting the rod, the first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8 cooperate together to support and position the rod to be cut, avoiding the rod from shaking during cutting. After cutting is completed, the rod will be pushed backward through the openings on the outer sides of the second support block 6, the third support block 7 and the auxiliary support block 8.

[0034] Among them, a spring is arranged on the outer side of each of the push rod supports 11, and the spring can push the blanking push block 12 and the push rod supports 11 to slide backward under the support of the push block support frame 10. When the rod cutting is completed, the opening on the outer side of the auxiliary support block 8 will face backward. At this time, the spring on the outer side of the push rod supports 11 can push the blanking push block 12 to move backward rapidly. Therefore, the cut rod can be pushed backward to separate it from the second support block 6, the third support block 7 and the auxiliary support block 8, and there is no need to manually remove the cut rod, making the operation more convenient when cutting the rod.

[0035] Among them, twelve convex teeth are arranged at the upper position at the rear side of each of the push rods 9, twelve corresponding tooth grooves are arranged on the outer side of each of the auxiliary support blocks 8, and these twelve tooth grooves account for one quarter of the outer circumference of the auxiliary support block 8. When the push rod 9 moves up and down, it can drive the auxiliary support block 8 to rotate through the cooperation of the convex teeth at its rear side and the tooth grooves on the outer side of the auxiliary support block 8, so as to change the orientation of the opening on the outer side of the auxiliary support block 8. Before cutting the rod, the push rod 9 will be at the lowest point. At this time, the opening on the outer side of the auxiliary support block 8 faces upward. Therefore, the auxiliary support block 8 can cooperate with the second support block 6 and the third support block 7 to fix the rod in the round hole in the middle. During the process of cutting the rod, the push rod 9 moves up to drive the auxiliary support block 8 to rotate. After cutting is completed, the opening on the outer side of the auxiliary support block 8 will face backward. Therefore, the cut rod can be released.

[0036] Among them, the rear sides of the blanking push blocks 12 are all wedge-shaped block structures, and when the blanking push blocks 12 slide to the rearmost side, the rear right side thereof will be located in front of the foremost position of the middle circular holes of the first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8. When cutting a rod, first pass the left end of the rod through the circular holes in the middle of the first support block 5, the third support block 7 and the second support block 6 in sequence and press it against the right side surface of the side baffle 2. During this process, the left end of the rod will first contact the inclined surface at the rear of the blanking push block 12, so that the blanking push block 12 and the push block support rod 11 can be automatically pushed forward to slide, and there is no need to manually pull the blanking push block 12 and the push block support rod 11 forward when fixing the rod.

[0037] Specific usage method and function of this embodiment: In the present invention, when using this device to cut a rod, first place this device on a suitable position through the bottom plate 1 for support, and then control the electric cylinder 3 to contract to drive the length measuring plate 4 to move down to the lowest point. At this time, the push rod 9 will be at the lowest point, and then the opening on the outside of the auxiliary support block 8 can be made to face upward. Then, adjust the position of the cutting knife wheel 15 according to the length of the rod to be cut. When adjusting, just loosen the knob on the right side of the top of the support sleeve 13 first, and then the position of the support sleeve 13 can be adjusted by sliding left and right. The cooperation between the support sleeve 13 and the scale on the top of the length measuring plate 4 can adjust the distance between the cutting knife wheel 15 and the side baffle 2. After the adjustment is completed, tighten the knob on the right side of the top of the support sleeve 13 to position it, so that rods of different lengths can be cut. Then, pass the left end of the rod through the circular holes in the middle of the first support block 5, the third support block 7 and the second support block 6 in sequence and press it against the right side surface of the side baffle 2. During this process, the left end of the rod will first contact the inclined surface at the rear of the blanking push block 12, so that the blanking push block 12 and the push block support rod 11 can be automatically pushed forward to slide, and there is no need to manually pull the blanking push block 12 and the push block support rod 11 forward when fixing the rod. The first support block 5, the second support block 6, the third support block 7 and the auxiliary support block 8 cooperate together to support and position the rod to be cut, avoiding the rod from shaking during cutting. At this time, then power on and start the motor 14 to drive the cutting knife wheel 15 to rotate at a high speed, and control the electric cylinder 3 to extend to push the length measuring plate 4 to move upward. Therefore, the motor 14 at the rear of the support sleeve 13 and the cutting knife wheel 15 can move upward synchronously to cut the rod, and at the same time, the two push rods 9 can move upward synchronously, so that the two auxiliary support blocks 8 rotate. After the cutting is completed, the opening on the outside of the auxiliary support block 8 will face backward, so that the cut rod can be released. At this time, the spring on the outside of the push block support rod 11 can push the blanking push block 12 to move backward quickly, so that the cut rod can be pushed backward to disengage from the second support block 6, the third support block 7 and the auxiliary support block 8, and there is no need to manually remove the cut rod, making the operation more convenient when cutting the rod.
