Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a device for drilling holes in a barrier block. Background Technology

[0002] In projectile launching experiments, the projectile is first fixed to the sabot. Compressed high-pressure air is used to propel the test projectile forward to a certain speed. To avoid the sabot affecting the projectile's trajectory, multiple arresting blocks are usually installed in the gun barrel with bolts. The arresting blocks block the sabot. After the sabot collides with the arresting block, the bolts are sheared, and the arresting block flies out of the gun barrel along with the sabot. To increase shearing force, one end of the barrier block is usually triangular, and multiple threaded holes evenly spaced along its length need to be machined on its surface. In the prior art, the barrier block is usually placed directly in a limiting fixture, and drilling is performed on it using a drilling machine. After machining one threaded hole, the barrier block is moved until all threaded holes are machined. In actual processing, only one barrier block can be machined at a time, and after one threaded hole is machined, the barrier block needs to be manually moved, resulting in low processing efficiency and hindering the improvement of production efficiency. Furthermore, different sizes and specifications of barrier blocks require different fixtures, which increases the cost of the fixtures. Summary of the Invention

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a barrier block drilling device that can process multiple barrier blocks at the same time, improve production efficiency, and can also adapt to barrier blocks of different sizes, with high versatility and strong practicality.

[0004] To achieve the above objectives, the present invention employs the following techniques: A blocking block drilling device includes: a base, a clamping mechanism, and a drilling mechanism.

[0005] The top surface of the base has concentric first and second annular grooves arranged sequentially from the center outwards. The clamping mechanism includes a rotating ring rotatably mounted at the center of the base and multiple side frames located around the base. The outer side of the rotating ring has multiple equally spaced limiting plates that move radially. The limiting plates are L-shaped and located in the first annular groove, used to support the flat end of the blocking block. The side frames rotate synchronously with the rotating ring, and the inner side has two support plates located in the second annular groove, symmetrically arranged and moving towards each other. The support plates move along their width direction to support the tip of the blocking block. The support plates have positioning rods for limiting the side of the blocking block. The drilling mechanism includes a lifting plate located above the base and moving vertically. The lifting plate has multiple moving blocks that move radially along the base along the circumference. Below the moving blocks is a drill bit that rotates around its own axis for drilling holes in the blocking block.

[0006] Furthermore, a push rod is provided on the side of the limiting plate. The push rod passes through the rotating ring and has a retaining ring at its end. A first spring is sleeved on the push rod. The two ends of the first spring abut against the rotating ring and the retaining ring respectively, and are always in a compressed state.

[0007] Furthermore, the outer wall of the rotating ring is provided with multiple spaced top plates along the circumferential direction. The ends of the top plates are flush with the vertical surface of the limiting plate away from the axis of the rotating ring, and are used to abut against the flat end of the blocking block.

[0008] Furthermore, the base surface is provided with multiple spaced and vertically connected long grooves along the circumferential direction. The long grooves are arranged radially along the base, and one end of each long groove is located in the second annular groove. The other end of one of the long grooves is located in the first annular groove for passing through the blocking block. The remaining long grooves are spaced apart from the first annular groove.

[0009] Furthermore, the inner wall of the first annular groove is provided with a notch, which is aligned and connected with one of the long grooves. When one of the limiting plates is located in the notch, one of the limiting plates is located on the outside of the long groove, and the inner side of the other limiting plates is always in contact with the inner wall of the first annular groove.

[0010] Furthermore, a support plate is rotatably installed on both sides of one of the long grooves along its length. The support plate is located in the area between the first and second annular grooves. A support rod is provided below the support plate and is movable along its width direction. The support rod contacts the bottom surface of the support plate and is used to lift the support plate. When lifted, the support plate is flush with the top surface of the base.

[0011] Furthermore, the upper end of the positioning rod is provided with a screw perpendicular to its axis. The screw passes through the vertical plate and is locked with a nut. The upper and lower ends of the vertical plate are respectively fitted onto two slide rods that are vertically spaced and installed on the side frame.

[0012] Furthermore, the slide rod is provided with retaining rings, which are arranged alternately. One retaining ring is attached to the upper end of one of the vertical plates, and the other retaining ring is attached to the lower end of another vertical plate. A second spring is sleeved on the slide rod between the two vertical plates. The two ends of the second spring abut against the inner side of the retaining ring and the vertical plate, respectively, and are always in a compressed state.

[0013] Furthermore, the side frame is provided with a horizontal plate that moves vertically. Both ends of the horizontal plate are provided with two limiting rods. The limiting rods include two vertical sections and an inclined transition section connecting the two vertical sections. The upper vertical section is connected to the horizontal plate, and the distance between the lower vertical section and the center of the side frame is greater than the distance between the upper vertical section and the center of the side frame. In application, the limiting rods contact the vertical plate.

[0014] Furthermore, the top surface of the horizontal plate is provided with a locking block, which is inverted L-shaped. Above one of the long slots is a locking plate that moves vertically. When in use, the locking plate engages with the locking block.

[0015] Furthermore, the drill bit is detachably installed at the end of the rotating shaft, which is rotatably installed in the moving block and one end is connected to the output end of the power equipment. The top surface of the lifting plate has multiple spaced elongated holes along its circumference. The moving block is slidably fitted in the elongated holes and locked with bolts. The lifting plate is connected to the moving end of the vertical lifting mechanism, which is installed on the support frame, which is installed on the base.

[0016] The advantages of this invention are as follows: multiple blocking blocks can be moved simultaneously by rotation, and multiple drilling stations are set up, so that multiple blocking blocks can be processed at the same time, improving production efficiency; the limiting plate provides support and limitation for the flat end of the blocking block, while the movable support plate and positioning rod support and limit the tip of the blocking block; thus, blocking blocks of different sizes can be clamped, improving versatility.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0026] like Figures 1-7As shown in the figure, this application provides a blocking block drilling device, including: a base 100, a clamping mechanism 200, and a drilling mechanism 300.

[0027] The top surface of the base 100 is provided with concentric first annular grooves 101 and second annular grooves 102 from the center outwards. The clamping mechanism 200 includes a rotating ring 201 rotatably mounted at the center of the base 100 and multiple side frames 203 located around the base 100. Multiple equally spaced limiting plates 202 are provided on the outer side of the rotating ring 201 and are radially movable. The limiting plates 202 are L-shaped and located in the first annular groove 101, used to support the flat end of the blocking block 400, and the flat end of the blocking block 400 abuts against the vertical surface of the limiting plate 202. The side frames 203 rotate synchronously with the rotating ring 201, and each side has two corresponding side frames located in the second annular groove 102. The support plates 204 are symmetrically arranged and move towards each other. The support plates 204 are movable along their width direction to support the tip of the blocking block 400. The support plates 204 are provided with positioning rods 205, which contact the inclined surface of the blocking block 400 to support and limit the blocking block 400. The drilling mechanism 300 includes a lifting plate 301 located above the base 100 and moving in the vertical direction. The lifting plate 301 is provided with a plurality of moving blocks 302 that move radially along the base 100 in the circumferential direction. A drill bit 303 is provided below the moving blocks 302 and rotates around its own axis to drill holes in the blocking block 400.

[0028] Specifically, the surface of the base 100 is provided with a plurality of spaced-apart elongated grooves 103 that run vertically through the circumference. The elongated grooves 103 are arranged radially along the base 100, and one end of each groove is located in the second annular groove 102. The other end of one of the elongated grooves 103 is located in the first annular groove 101 for passing through the blocking block 400. The other ends of the remaining elongated grooves 103 are spaced from the first annular groove 101 for passing through the waste chips generated during drilling. When the blocking block 400, after drilling is completed, moves above one of the elongated grooves 103, the limiting plate 202 located above one of the elongated grooves 103 moves toward the axis of the rotating ring 201 until the limiting plate 202 is located outside the elongated groove 103. At the same time, the support plates 204 are moved away from each other, and the blocking block 400 can fall from the elongated groove 103.

[0029] Specifically, in order to enable the limiting plate 202 to automatically move away from the top of the long groove 103, a notch is provided on the inner wall of the first annular groove 101. The notch is aligned and connected with one of the long grooves 103. When one of the limiting plates 202 is rotated to the outside of the notch, the limiting plate 202 moves toward the center of the rotating ring 201. The blocking block 400 will not move due to the obstruction of the top plate 218. The blocking block 400 is always located above the long groove 103. At this time, the blocking block 400 can fall from the long groove 103. The inner side of the remaining limiting plates 202 is always in contact with the inner wall of the first annular groove 101 to ensure the supporting effect on the blocking block 400.

[0030] Specifically, the limiting plate 202 has a push rod 206 on its side, which passes through the rotating ring 201 and has a retaining ring 207 at its end. A first spring 208 is sleeved on the push rod 206. The two ends of the first spring 208 abut against the rotating ring 201 and the retaining ring 207 respectively, and are always in a compressed state. At this time, the limiting plate 202 is limited by the first ring groove 101. Under the action of the first spring 208, the limiting plate 202 always tends to move toward the axis of the rotating ring 201. When it is necessary to let the blocking block 400 fall from one of the long grooves 103, the limiting plate 202 is moved to the outside of the notch. The limiting plate 202 will move toward the axis of the rotating ring 201 under the action of the first spring 208 until it is completely inserted into the notch. At this time, the limiting plate 202 no longer provides support for the blocking block 400 and moves the two support plates 204 away from each other, so that the blocking block 400 can fall from the long groove 103.

[0031] Specifically, the outer wall of the rotating ring 201 is provided with a plurality of spaced top plates 218 along the circumferential direction. The ends of the top plates 218 are flush with the vertical surface of the limiting plate 202 away from the axis of the rotating ring 201, and are used to abut against the flat end of the blocking block 400. When the limiting plate 202 moves toward the center of the rotating ring 201, the blocking block 400 will not move synchronously with the limiting plate 202 under the blocking action of the top plates 218, ensuring that the blocking block 400 can fall smoothly from the long groove 103.

[0032] The rotation of the rotating ring 201 can be mounted on a drive shaft, which is rotatably mounted at the center of the base 100. The side frame 203 is also connected to the drive shaft via a bracket. When the drive shaft rotates, the rotating ring 201 and the side frame 203 can be driven to rotate synchronously at the same time. For the rotation of the drive shaft, only one end needs to be connected to the output end of the rotating motor.

[0033] Specifically, since the movement of the limiting plate 202 and the support plate 204 is not synchronous, in order to ensure that the blocking block 400 can fall smoothly from the long groove 103, a support plate 104 is rotatably installed on both sides of the length direction of one of the long grooves 103. The support plate 104 is located in the area between the first annular groove 101 and the second annular groove 102. A support rod 105 is provided below the support plate 104 and is movable along its width direction. The support rod 105 contacts the bottom surface of the support plate 104 and is used to lift the support plate 104. When lifted, the top surface of the support plate 104 is flush with the top surface of the base 100. When the blocking block 400 is above one of the long slots 103, the two support rods 105 are moved away from each other until they are located outside the long slot 103. The support plate 104 will then rotate downwards under its own weight. At this time, the blocking block 400 can fall from the long slot 103. Then, the two support rods 105 are moved towards each other, and the support plate 104 will be lifted up and reset. The movement of the support rods 105 can be driven by a horizontal linear mechanism. The horizontal linear mechanism is arranged along the width direction of the long slot 103. The horizontal linear mechanism can be a cylinder or a motor screw structure.

[0034] Specifically, the upper end of the positioning rod 205 is provided with a screw 209 perpendicular to its axis. The screw 209 passes through the vertical plate 210 and is locked with a nut. Both the upper and lower ends of the vertical plate 210 are fitted onto the slide rod 211, which is installed on the side frame 203. When it is necessary to support and limit the blocking blocks 400 of different sizes, the nut is loosened and the screw 209 is moved. Then, the nut is used to lock the screw 209, thereby adjusting the position of the positioning rod 205.

[0035] Specifically, the slide rod 211 is provided with retaining rings 212, which are arranged alternately. The outer side of one retaining ring 212 is attached to the upper end of one of the vertical plates 210, and the outer side of the other retaining ring 212 is attached to the lower end of the other vertical plate 210. A second spring 213 is sleeved on the slide rod 211 between the two vertical plates 210. The two ends of the second spring 213 abut against the inner side of the retaining ring 212 and the vertical plate 210 respectively, and are always in a compressed state. Under the action of the second spring 213, the two vertical plates 210 always tend to move away from each other. When it is necessary to support and limit the blocking block 400, a force is applied to the vertical plate 210 toward the center of the side frame 203, which further compresses the second spring 213 until the two support plates 204 come into contact with each other. At this time, the positioning rod 205 just contacts the inclined surface of the blocking block 400, realizing the support and limitation of the tip of the blocking block 400.

[0036] Specifically, the side frame 203 is provided with a horizontal plate 214 that moves vertically. Both ends of the horizontal plate 214 are provided with two limiting rods 215. The limiting rods 215 include two vertical sections and a transition section connecting the two vertical sections. The distance between the lower vertical section and the center of the side frame 203 is greater than the distance between the upper vertical section and the center of the side frame 203. The upper vertical section is connected to the horizontal plate 214. When it is necessary to support the tip of the blocking block 400, the upper vertical section contacts the side of the vertical plate 210. When it is necessary to release the support of the blocking block 400, the horizontal plate 214 is moved upward. The vertical plate 210 will move under the action of the second spring 213 until it contacts the lower vertical section. Then the two support plates 204 move away from each other, and the blocking block 400 can fall smoothly.

[0037] Specifically, the top surface of the horizontal plate 214 is provided with a locking block 216, which is inverted L-shaped. Above one of the long slots 103, there is a locking plate 217 that moves vertically. When one of the side frames 203 rotates to the outer end of one of the long slots 103, the locking plate 217 engages with the locking block 216. Then, the locking plate 217 is moved upward, which drives the horizontal plate 214 to move upward synchronously, releasing the limit applied to the vertical plate 210. The two support plates 204 can then move away from each other under the action of the second spring 213. After the blocking block 400 falls, the locking plate 217 is moved downward, which drives the horizontal plate 214 to move downward, reapplying force to the vertical plate 210, so that the two support plates 204 come into contact with each other to provide support for the blocking block 400. The movement of the locking plate 217 can be achieved by connecting it to the moving end of a vertical lifting mechanism, such as a cylinder or motor screw structure.

[0038] Specifically, the drill bit 303 is detachably mounted on the end of the rotating shaft 304. For threaded holes of different diameters, the drill bit 303 can be replaced. The rotating shaft 304 is rotatably mounted in the moving block 302, and one end is connected to the output end of the power equipment. The power equipment can be a rotary motor. The top surface of the lifting plate 301 has multiple spaced elongated holes 305 along its circumference. The moving block 302 is slidably fitted in the elongated holes 305 and locked with bolts. The lifting plate 301 is connected to the moving end of the vertical lifting mechanism. The vertical lifting mechanism is mounted on the support frame 306, and can be a telescopic cylinder or a motor screw mechanism. The support frame 306 is mounted on the base 100. When drilling is required on the block 400 at different drilling positions, the bolts are loosened, the moving block 302 is moved, and then the bolts are tightened. Afterwards, the vertical lifting mechanism drives the lifting plate 301 to move downward, and the rotating shaft 304 rotates synchronously, so that multiple block 400 can be drilled at the same time, improving production efficiency.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
