Description

Technical Field

[0001] The utility model belongs to the technical field of blanking devices, and particularly relates to a new type of blanking power head. Background Art

[0002] At present, in the existing blanking devices, pneumatic grippers are mostly used for blanking. During the blanking process of pneumatic grippers, when the pneumatic gripper clamps the material (generally metal parts), a clamping cylinder is required, and when lifting the material, a lifting cylinder is needed to drive it. When the material is stored in the collector, a conveying cylinder is also required. The structure of the whole device is complex and the working process is cumbersome. Moreover, during the working process of the cylinders, each cylinder consumes a certain amount of time, the action is slow, and the working efficiency is low.

[0003] Therefore, the utility model provides a blanking power head to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a new type of blanking power head, which solves the problems of complex structure, time-consuming and low efficiency, and has the technical effects of simple structure and improved working efficiency.

[0005] A new type of blanking power head includes a spring collet, a movement mechanism for driving the spring collet to perform linear up and down movement. The movement mechanism is connected to a conveying mechanism for conveying materials. A power cylinder is sleeved outside the conveying mechanism, and a thimble for blanking is sleeved inside the power cylinder.

[0006] The movement mechanism includes a main shaft cylinder. One end of the main shaft cylinder is coaxially sleeved and fixedly connected to the outside of one end of the spring collet. The other end of the main shaft cylinder passes through a through hole one at one end of the bracket and is fixedly connected. The inner side of the main shaft cylinder is coaxially sleeved on the outside of the thimble. The outside of the main shaft cylinder is coaxially sleeved with a power cylinder. One end of the power cylinder is provided with two parallel long blocks.

[0007] One end of the main shaft cylinder is conical.

[0008] The power cylinder is connected to the conveying mechanism.

[0009] On the outside of the other end of the spring collet along the axial direction of the spring collet, a plurality of long strip through slots are provided and form a wide-mouth structure.

[0010] Two linear bearings and a bushing are coaxially sleeved on the outside of the main shaft cylinder.

[0011] The bushing is located between the two linear bearings.

[0012] The two linear bearings and the bushing are located between the main shaft cylinder and the power cylinder.

[0013] The conveying mechanism includes two clamping jaws. One end of each of the two clamping jaws is respectively passed through the two ends of the two rectangular blocks through a control shaft, and the other ends of the two clamping jaws are in separable contact.

[0014] Two spring shafts are respectively passed through the sides of the two clamping jaws. Rolling bearings are respectively sleeved on the outer sides of the coaxial centers of the two spring shafts. One end of each of the two spring shafts is fixed by a snap ring, and the other ends of the two spring shafts are connected by a tension spring;

[0015] The two rolling bearings are slidably connected to the main shaft cylinder;

[0016] The other ends of the two clamping jaws are respectively provided with inclined surfaces with the same slope.

[0017] One end of the ejector pin is in separable contact with the material inside the spring collet. The other end of the ejector pin passes through the through hole two on the side of the limit plate and is connected to an adjusting bolt. The through holes three and four at both ends of the limit plate are respectively connected to one end of a support rod through bolt one and bolt two. The other ends of the two support rods are passed through the surface of the power cylinder.

[0018] The utility model achieves the following remarkable effects:

[0019] (1) One end of the main shaft cylinder is coaxially sleeved on the outside of one end of the spring collet, and the other end of the main shaft cylinder passes through the through hole one at one end of the bracket and is fixedly connected. The spring collet is driven to move up and down by the movement of the bracket to clamp the material, and the structure is simple.

[0020] (2) The adjusting bolt provided at one end of the ejector pin can adjust the height of the ejector pin according to the size of the material.

[0021] (3) One end of each of the two clamping jaws is provided with a rolling bearing and a tension spring. The other ends of the two clamping jaws are respectively provided with inclined surfaces with the same slope, and one end of the main shaft cylinder is conical. When the spring collet moves down, the rolling bearing drives the clamping jaws to be located at the position with a larger diameter of the main shaft cylinder. At this time, the other ends of the clamping jaws open. When the spring collet clamps the material and moves up, due to the pulling force of the tension spring, the rolling bearing drives the two clamping jaws to move down. As the diameter of the main shaft cylinder slowly decreases, the other ends of the two clamping jaws close. After closing, they form a relatively large inclined surface. When the main shaft cylinder drives the spring collet to continue to move up, the ejector pin inside the main shaft cylinder ejects the material out of the spring collet and falls onto the inclined surface and then enters the collector. The rolling bearing can make the movement of the clamping jaws smooth, and the inclined surface can prevent the material from being damaged due to too high a height. The device is simple and has high working efficiency. Description of the Drawings

Specific embodiments

[0027] In order to more clearly illustrate the technical features of the present solution, the present solution will be elaborated below through specific embodiments.

[0028] See Figures 1-4 , a new type of blanking power head, including a spring collet 10, a motion mechanism for driving the spring collet 10 to perform linear up and down motion, the motion mechanism is connected to a conveying mechanism for conveying materials, the outside of the conveying mechanism is sleeved with a power cylinder 17, and the inside of the power cylinder 17 is provided with an ejector pin 19 for blanking.

[0029] The motion mechanism includes a main shaft cylinder 20. One end of the main shaft cylinder 20 is coaxially sleeved on the outside of one end of the spring collet 10 and fixedly connected. The other end of the main shaft cylinder 20 passes through a through hole 1 in one end of the bracket 15 and is fixedly connected. The inside of the main shaft cylinder 20 is coaxially sleeved on the outside of the ejector pin 19. The outside of the main shaft cylinder 20 is coaxially sleeved with a power cylinder 17. One end of the power cylinder 17 is provided with two parallel long blocks 21, and the two long blocks 21 are used to connect the two jaws 11.

[0030] One end of the main shaft cylinder 20 is tapered. When the jaws 11 move up and down on the main shaft cylinder 20 by relying on the rolling bearings 112 on the jaws 11, at the same time relying on the tension of the tension spring 12, when the jaws 11 are at the thicker end of the main shaft cylinder 20, the opening angle of the jaws 11 is the largest. When the main shaft cylinder 20 moves up, the rolling bearings 112 slide along the inclined surface of the main shaft cylinder 20, and the jaws 11 are slowly closed by relying on the tension of the tension spring 12.

[0031] The power cylinder 17 is connected to the conveying mechanism, and the power cylinder 17 can protect internal components such as the linear bearing 172 and the bushing 171.

[0032] The other end of the spring chuck 10 is provided with a plurality of long through grooves along the axial direction of the spring chuck 10 to form a wide-mouth structure. The spring chuck 10 itself has a certain elasticity. The inner diameter of the chuck is slightly smaller than the maximum outer diameter of the clamped part. When the clamped part is squeezed into the chuck, the chuck is stretched open a little and the material is clamped by elastic force and friction.

[0033] Two linear bearings 172 and a bushing 171 are coaxially sleeved on the outer side of the main shaft cylinder 20. The bushing 171 plays a supporting role. The linear bearing 172 can reduce wear, vibration and noise between components when in use, and has an anti-corrosion effect.

[0034] The bushing 171 is located between two linear bearings 172;

[0035] The two linear bearings 172 and the bushing 171 are located between the main shaft cylinder 20 and the power cylinder 17 .

[0036] The conveying mechanism includes two clamping jaws 11 , one end of the two clamping jaws 11 is respectively penetrated through the two ends of the two rectangular blocks 21 through the control shaft 113 , and the other ends of the two clamping jaws 21 are in separate contact.

[0037] The two spring shafts 111 are respectively passed through the sides of the two clamping jaws 11, and rolling bearings 112 are respectively sleeved on the coaxial outer sides of the two spring shafts 111. One ends of the two spring shafts 111 are respectively fixed by retaining springs, and the other ends of the two spring shafts 111 are connected by tensioning springs 12. The rolling bearings 112 make the clamping jaws 11 move smoothly on the main shaft cylinder 20, and the tensioning springs 12 can provide power for the closing of the two clamping jaws 11.

[0038] The two rolling bearings 112 are slidably connected to the main shaft cylinder 20 . When the main shaft cylinder 20 moves up and down, the rolling bearings 112 will contact positions of different outer diameters of the main shaft cylinder 20 , thereby driving the clamping jaws 11 to close and open.

[0039] The other ends of the two clamping jaws 11 are respectively provided with inclined surfaces of the same slope. When the main shaft cylinder 20 moves upward and the rolling bearing 112 moves downward along the conical surface, the two clamping jaws 11 are brought closer together by relying on the tension of the tension spring 12. After being brought closer together, the inclined surfaces at one end of the two clamping jaws 11 will form a larger inclined surface, which is convenient for the transportation of materials.

[0040] One end of the thimble 19 is in separable contact with the material inside the spring collet 10. The other end of the thimble 19 passes through the second through hole on the side of the limit plate 13 and is connected to the adjusting bolt 18. The third through hole and the fourth through hole at both ends of the limit plate 13 are respectively connected to one end of the support rod 16 through the first bolt and the second bolt. The other ends of the two support rods 16 are arranged on the surface of the power cylinder 17. According to the size of the material, turn the adjusting bolt 18 to fix the thimble 19 at a suitable position. The thimble 19 is coaxially sleeved inside the main shaft cylinder 20. When the main shaft cylinder 20 drives the spring collet 10 to move upward, the thimble 19 ejects the material on the spring collet 10. At this time, the material falls onto the inclined plane formed by the two jaws 11, and then slides out along the inclined plane and falls into the prepared collector.

[0041] The specific working process of the present utility model:

[0042] See Figures 1-4 , one end of the thimble 19 is in separable contact with the material inside the spring collet 10. The other end of the thimble 19 passes through the second through hole on the side of the limit plate 13 and is connected to the adjusting bolt 18. The third through hole and the fourth through hole at both ends of the limit plate 13 are respectively connected to one end of the support rod 16 through the first bolt and the second bolt. The other ends of the two support rods 16 are arranged on the surface of the power cylinder 17. According to the size of the material, turn the adjusting bolt 18 to fix the thimble 19 at a suitable position.

[0043] One end of the main shaft cylinder 20 is coaxially sleeved and fixedly connected to the outside of one end of the spring collet 10. The other end of the main shaft cylinder 20 passes through the first through hole at one end of the bracket 15 and is fixedly connected. When the lever on the station machine provides power to the bracket 15, the bracket 15 can drive the spring collet 10 to move up and down.

[0044] Two linear bearings 172 and a bushing 171 are coaxially sleeved on the outside of the main shaft cylinder 20. The linear bearings 172 play a supporting role. The bushing 171 can reduce the wear, vibration and noise between components during use, and has an anti-corrosion effect. The two linear bearings 172 and the bushing 171 are located between the main shaft cylinder 20 and the power cylinder 17, and the power cylinder 17 plays a role in protecting the internal components.

[0045] One end of the main shaft cylinder 20 is set to be conical. One end of each of the two jaws 11 passes through the two ends of the two long blocks 21 through the control shaft 113 respectively. The other ends of the two jaws 21 are in separable contact. Two spring shafts 111 pass through the two ends of the two jaws 11 respectively. Rolling bearings 112 are sleeved on the coaxial outside of the two spring shafts 111 respectively. One end of each of the two spring shafts 111 is fixed by a circlip. The other ends of the two spring shafts 111 are connected by a tension spring 12. When the bracket 15 drives the main shaft cylinder 20 to move upward, the rolling bearings 112 move downward along the conical surface of the main shaft cylinder 20, and the two jaws 11 are brought closer together by the tension of the tension spring 12.

[0046] One end of each of the two clamping jaws 11 is set as an inclined surface, and a larger inclined surface is formed after they come closer. When the collet chuck 10 clamps the material and moves upward, the material is ejected by the ejector pin 19 inside the main shaft cylinder 20. The material falls on the inclined surface at one end of the clamping jaw 11 and then falls into a pre-prepared collector along the inclined surface, completing the discharging work of the material.

Of course, the above description is not a limitation on the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present utility model should also fall within the protection scope of the present utility model.
