Description

Technical Field

[0001] This utility model relates to a drilling device, specifically an automatic drilling device for a vibration table surface. Background Technology

[0002] A vibration table is a device that generates controllable mechanical vibrations in a laboratory using principles such as electric, electro-hydraulic, mechanical, or piezoelectricity. Vibration excitation is applied to specimens fixed to the table surface to assess their vibration resistance, reliability, and structural integrity. The vibration table surface typically has various slots and holes to facilitate the fixed connection between the specimen and the table surface; these holes are usually drilled using a milling machine.

[0003] A typical milling machine consists of a worktable and a machining module. After the sheet metal is placed on and clamped on the worktable, the machining module performs drilling operations on the sheet metal. Generally, the drilling position is controlled by controlling the relative position of the machining module, which can improve machining accuracy and reduce the machine's footprint.

[0004] The surface of a typical vibration table is relatively large, making it difficult to position the sheet material after it is placed on the worktable. It is often necessary to move the sheet material repeatedly to adjust its position. During the adjustment process, the sheet material rubs against the worktable repeatedly, which inevitably reduces the surface quality of the sheet material. Moreover, after long-term use, the friction wear of the worktable is large, which can easily affect the subsequent processing accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic drilling device for a vibration table surface to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic drilling device for a vibration table surface includes a housing; the housing is equipped with a mounting plate, a worktable, and a processing module. It also includes clamping components, which are disposed on the worktable and include multiple sets of clamping plates, which are symmetrically arranged; and the multiple sets of clamping plates can move closer to each other along the width direction of the worktable to clamp the material. A support frame is mounted on the mounting plate, and a roller is rotatably mounted on the support frame; a brake shaft is mounted on one end of the roller. It also includes a braking component that cooperates with the clamping component, which is disposed on the support frame and includes a sliding clamping plate that radially compresses the brake shaft.

[0007] The automatic drilling device for the vibration table surface as described above includes a clamping component that further includes a motor mounted on the worktable. A main shaft, multiple clamping shafts, and a transmission shaft are rotatably mounted on the worktable. The transmission shaft is connected to the clamping shafts and the main shaft via a bevel gear set. The main shaft is connected to the output end of the motor via a belt. Multiple sets of threaded grooves are symmetrically formed on the clamping shafts. Threaded sleeves that are threadedly connected to the threaded grooves are respectively fitted onto both ends of the clamping shafts. The threaded sleeves are slidably fitted into the worktable and fixedly connected to the clamping plate.

[0008] The automatic drilling device for the vibration table surface as described above: an inclined positioning plate is installed on the clamping plate.

[0009] The automatic drilling device for the vibration table surface as described above includes a braking component that further includes a fixing block mounted on the support frame; a fixing clamp plate rotatably connected to the brake shaft is installed inside the fixing block; the fixing block and the sliding clamp plate are slidably engaged; a spring is provided inside the fixing block, and the two ends of the spring respectively abut against the fixing block and the sliding clamp plate.

[0010] The automatic drilling device for the vibration table surface as described above: a wedge is installed on the sliding clamp; an abutting plate that abuts against the wedge is installed on the threaded sleeve; and a groove is opened on the abutting plate.

[0011] The automatic drilling device for the vibration table surface as described above: an inclined ramp is installed on the mounting plate; and a chip removal groove that cooperates with the ramp is provided on the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: During the drilling process on the vibrating table, the rolling friction between the rollers and the plate reduces the feeding resistance during the loading and positioning of the plate (manual rough adjustment and clamping positioning). This effectively increases the feeding rate and reduces frictional wear between the plate and the worktable, thus improving both product quality and the lifespan of the device. Before processing begins after the plate is centered, the rollers are locked by a brake, transforming the rolling friction between the plate and the rollers into static friction. This increases the rigidity of the entire device, reduces vibration during processing, and results in smoother drilling and better hole wall quality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-6 As an embodiment of the present utility model, the automatic drilling device for the vibration table surface includes a housing 1; the housing 1 is equipped with an mounting plate 101, a worktable 3 and a processing module 2; It also includes clamping components, which are disposed on the worktable 3, including multiple sets of clamping plates 4, which are symmetrically arranged; and the multiple sets of clamping plates 4 can move closer to each other along the width direction of the worktable 3 to clamp the plate. A support frame 102 is mounted on the mounting plate 101, and a roller 5 is rotatably mounted on the support frame 102; a brake shaft 501 is mounted on one end of the roller 5. It also includes a braking component that cooperates with the clamping component, which is disposed on the support frame 102 and includes a sliding clamping plate 13 that radially compresses the brake shaft 501.

[0022] In this embodiment, the processing module 2 is used to drill holes in the sheet metal.

[0023] When drilling holes in the vibrating table surface, place the pre-treated plate on workbench 3 and adjust its approximate position.

[0024] The plate is then clamped and positioned by clamping components. This is achieved by moving multiple clamping plates 4 closer together, gradually shortening the distance between them. During this process, the clamping plates 4 come into contact with the plate and move it after contact, causing the plate's centerline (including the transverse and longitudinal centerlines) to gradually coincide with the centerline of the worktable 3. After the centerlines coincide, the clamping plates 4 exert pressure on the plate, increasing the difficulty of the plate's movement on the worktable 3. This prevents large processing errors caused by plate displacement during drilling operations.

[0025] In the initial state, the sliding clamp 13 is not in contact with the brake shaft 501, so both the brake shaft 501 and the roller 5 can rotate freely.

[0026] During the clamping and positioning of the sheet metal, the rolling action between the roller 5 and the sheet metal reduces the friction between the sheet metal and the worktable 3, thereby reducing the frictional wear of the worktable 3 or the sheet metal.

[0027] After the plate is clamped and positioned, the roller 5 is locked by the brake, that is, the brake shaft 501 is radially squeezed by the sliding clamp 13, thereby increasing the resistance of the rotation of the brake shaft 501 and the roller 5, so as to further increase the resistance of the plate displacement when the processing module 2 processes the plate.

[0028] During the drilling process on the vibrating table, the rolling friction between the roller 5 and the plate reduces the feeding resistance during the plate loading and position adjustment (manual rough adjustment and clamping positioning). This effectively increases the feeding rate and reduces the frictional wear between the plate and the worktable 3, thus improving both product quality and the lifespan of the device. Before processing begins after the plate is centered, the roller 5 is locked by a brake, which transforms the rolling friction between the plate and the roller 5 into static friction. This increases the rigidity of the entire device, reduces vibration during processing, and results in smoother drilling and better hole wall quality.

[0029] As a further embodiment of this utility model, the clamping component also includes a motor 16 mounted on the worktable 3. A main rotating shaft 6, multiple sets of clamping rotating shafts 7, and a transmission rotating shaft 8 are rotatably mounted on the worktable 3. The transmission rotating shaft 8 is connected to the clamping rotating shafts 7 and the main rotating shaft 6 via a bevel gear set. The main rotating shaft 6 is connected to the output end of the motor 16 via a belt. Multiple sets of threaded grooves 701 are symmetrically formed on the clamping rotating shafts 7. Threaded sleeves 9 that are threadedly connected to the threaded grooves 701 are respectively sleeved at both ends of the clamping rotating shaft 7. The threaded sleeves 9 are slidably fitted into the worktable 3 and fixedly connected to the clamping plate 4.

[0030] In this embodiment, after the plate is placed on the workbench 3 and roughly adjusted, the motor 16 is started, which drives the main shaft 6 to rotate via the belt, and drives the transmission shaft 8 and the clamping shaft 7 to rotate via the bevel gear set, thereby driving the multiple sets of threaded grooves 701 to rotate.

[0031] The threaded grooves 701 on both ends of the clamping shaft 7 have opposite thread directions. Therefore, when the clamping shaft 7 rotates, the multiple sets of threaded grooves 701 and threaded sleeves 9 can be driven to move closer to each other through the threaded engagement of the threaded grooves 701 and the threaded sleeves 9, thereby driving the clamping plates 4 to move closer to each other along the width direction of the worktable 3.

[0032] During the approach process, the clamping plate 4 will come into contact with the plate and drive the plate to move after contact, so that the center line of the plate (including the horizontal center line and the vertical center line) gradually coincides with the center line of the worktable 3. After the center line coincides, the clamping plate 4 can increase the difficulty of the plate to move on the worktable 3 through the squeezing action of the plate, thereby avoiding large processing errors caused by the displacement of the plate during drilling operations.

[0033] As a further embodiment of this utility model, an inclined positioning plate 401 is installed on the clamping plate 4.

[0034] In this embodiment, the inclined positioning plate 401 will first come into contact with the corner of the plate as the clamping plates 4 approach each other. Through the squeezing action of the positioning plate 401 on the corner of the plate, the plate can be moved inward (the center line of the plate in the longitudinal direction gradually approaches the center line of the worktable 3 in the longitudinal direction). At the same time, through the squeezing action of the clamping plates 4 on the plate, the center line of the plate in the transverse direction gradually coincides with the center line of the worktable 3 in the transverse direction. This can effectively reduce the positioning difficulty of the processing module 2, thereby improving the processing accuracy.

[0035] As a further embodiment of this utility model, the braking component also includes a fixing block 11 mounted on the support frame 102; a fixing clamping plate 12 rotatably connected to the brake shaft 501 is installed inside the fixing block 11; the fixing block 11 is slidably engaged with the sliding clamping plate 13, and a spring 14 is provided inside the fixing block 11, with both ends of the spring 14 abutting against the fixing block 11 and the sliding clamping plate 13 respectively.

[0036] As a further embodiment of this utility model, a wedge block 15 is installed on the sliding clamp 13; an abutting plate 10 that abuts against the wedge block 15 is installed on the threaded sleeve 9; and a groove 1001 is provided on the abutting plate 10.

[0037] In this embodiment, in the initial state, the sliding clamp 13 is not in contact with the brake shaft 501, so both the brake shaft 501 and the roller 5 can rotate freely; at this time, the compression of the spring 14 is relatively large; and at this time, the wedge block 15 is in contact with the abutment plate 10.

[0038] During the clamping and positioning of the sheet metal, the rolling action between the roller 5 and the sheet metal reduces the friction between the sheet metal and the worktable 3, thereby reducing the frictional wear of the worktable 3 or the sheet metal.

[0039] When the plate is clamped and positioned, the threaded sleeves 9 will move closer to each other, thereby driving the abutment plate 10 to move, so that the wedge block 15 slides on the abutment plate 10 and the wedge block 15 will gradually move closer to the groove 1001.

[0040] When the longitudinal centerline of the plate coincides with the longitudinal centerline of the worktable 3 (the positioning plate 401 disengages from the plate), the continuing-moving clamping plate 4 will contact the plate. During this process, the wedge 15 will gradually approach the slot 1001. When the wedge 15 is aligned with the slot 1001, the elastic force of the spring 14 will drive the sliding clamp 13 to gradually approach the brake shaft 501 and abut against it. At this time, the brake shaft 501 is radially clamped by the fixed clamp 12 and the sliding clamp 13, thereby increasing the resistance to the rotation of the brake shaft 501 and locking the roller 5. During this process, the compression of the spring 14 gradually decreases, and the elastic force of the spring 14 provides a squeezing force to the sliding clamp 13.

[0041] During the drilling process on the vibrating table, the rolling friction between the roller 5 and the plate reduces the feeding resistance during the plate loading and position adjustment (manual rough adjustment and clamping positioning). This effectively increases the feeding rate and reduces the frictional wear between the plate and the worktable 3, thus improving both product quality and the lifespan of the device. Before processing begins after the plate is centered, the roller 5 is locked by a brake, which transforms the rolling friction between the plate and the roller 5 into static friction. This increases the rigidity of the entire device, reduces vibration during processing, and results in smoother drilling and better hole wall quality.

[0042] As a further embodiment of this utility model, an inclined ramp 17 is installed on the mounting plate 101; and a chip removal groove 103 that cooperates with the ramp 17 is provided on the mounting plate 101.

[0043] In this embodiment, the waste chips generated when the processing module 2 drills the plate will fall onto the ramp 17 and be guided into the chip discharge groove 103 by the ramp 17, which can improve the cleanliness of the workbench 3 and avoid the waste chips from interfering with the processing accuracy.

[0044] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
