Description

Technical Field

[0001] This utility model relates to the technical field of fixing devices, and in particular to a fixing device for machining irregularly shaped flat CNC machine tools. Background Technology

[0002] Currently, in some CNC machining processes, clamping is achieved by fixing the plate with bolts and then using calipers to measure and confirm its position. However, for irregularly shaped small flat plates, positioning and clamping are more difficult, resulting in low clamping efficiency and inaccurate positioning, which can easily lead to machining failure. Utility Model Content

[0003] To address the difficulty in positioning and clamping irregularly shaped small flat plates during CNC (Computer Numerical Control) machining, this invention provides a fixing device for CNC machining of irregularly shaped flat plates.

[0004] The present invention provides a fixing device for machining irregularly shaped flat CNC machine tools, which adopts the following technical solution:

[0005] A CNC machine tool fixing device for machining irregularly shaped flat plates includes a base plate, a clamping device, several bolts (first type), several bolts (second type), and several irregularly shaped flat plates. Each irregularly shaped flat plate is located between the base plate and the clamping device. The clamping device is movably connected to the top of the base plate by a corresponding bolt (first type). The clamping device includes a pad assembly, a pressure plate assembly, and several barrier plates. The pad assembly is located between each irregularly shaped flat plate and the base plate. The bottom of the pressure plate assembly is snapped onto the top of the corresponding irregularly shaped flat plate by a corresponding bolt (first type). The top of the base plate has several threaded holes (first type) and several threaded grooves. Each bolt (first type) is fixedly connected to the interior of the corresponding threaded hole (first type).

[0006] By adopting the above technical solution, the irregularly shaped plate is detachably connected to the top of the base plate through the cooperation of bolt one, several bolts two, and the clamping device. At the same time, the pad assembly has direct data, which facilitates quick and accurate positioning of the irregularly shaped plate after clamping it.

[0007] Preferably, the pad assembly includes two end pads and several knife pads. The two end pads are located at the two ends of the top of the base plate, and the several knife pads are divided into two groups. One group of knife pads is located between the bottom inner side and the corresponding irregular flat plate, and the other group of knife pads is located between the two corresponding irregular flat plates.

[0008] Preferably, the pressure plate assembly includes several long pressure plates and several short pressure plates. Each long pressure plate and each short pressure plate has three through holes. Each long pressure plate and each short pressure plate is located above a corresponding knife pad. One end of each long pressure plate overlaps the top of a corresponding irregularly shaped flat plate. The other end of each long pressure plate is near the end with a threaded groove on the bottom plate. Each short pressure plate is located above two corresponding knife pads.

[0009] Preferably, one end of the bottom of each of the irregularly shaped flat plates overlaps the top of the corresponding end pad, and the top of each of the two end pads is provided with eight through holes.

[0010] Preferably, each of the several knife pads has three stepped cylindrical holes and two corner slots at its top, and each of the corner slots has a cylindrical through hole near the middle end. One end of the bottom of each irregular plate overlaps the interior of the corresponding corner slot. Some of the bolts pass through the stepped cylindrical holes and are threaded into the interior of the corresponding threaded holes. The top of some of the bolts is engaged with the interior of the stepped cylindrical holes.

[0011] By adopting the above technical solution, the bottom of the irregularly shaped flat plate is clamped by the corner grooves of the two knife-shaped pads, and the top of the irregularly shaped flat plate is locked by the long pressure plate and the short pressure plate. This completes the clamping and positioning of the irregularly shaped flat plate, which helps to solve the problem of difficult positioning and clamping of irregularly shaped small flat plates.

[0012] Preferably, a portion of the bolt one penetrates the corresponding through hole two and the corresponding stepped cylindrical hole and is threaded into the interior of the corresponding threaded hole one, and the top of a portion of the bolt one is engaged with the top of the corresponding long pressure plate and the corresponding short pressure plate.

[0013] By adopting the above technical solution, once the bolt passes through the long pressure plate, the short pressure plate and the corresponding knife pad, and is threaded into the inside of the base plate, the irregularly shaped flat plate can be locked between the knife pad and the long pressure plate and the short pressure plate, making it convenient and quick to lock the knife pad.

[0014] Preferably, a portion of the bolts 1 penetrate the interior of the corresponding through hole 1 and are threadedly connected to the interior of the corresponding threaded hole 1, and the top of a portion of the bolts 1 is engaged with the top of the corresponding end pad, and each bolt 2 penetrates the corresponding through hole 2 and is threadedly connected to the interior of the corresponding threaded groove.

[0015] By adopting the above technical solution, the end pad is locked to the base plate by bolt one, which prevents the end pad from sliding relative to the bottom during processing. Bolt two cooperates with bolt one, so that the long pressure plate will not rotate when pressing the irregular plate, and can firmly cooperate with the knife pad to clamp the irregular plate.

[0016] Preferably, one side of each of the several barrier plates has an arc-shaped surface, and one side of each barrier plate is snapped onto the side of a corresponding irregularly shaped flat plate, wherein the top of a portion of the bolts is snapped onto the arc-shaped surface of the corresponding barrier plate.

[0017] By adopting the above technical solution, the barrier plate is fastened by bolts, thereby locking one side of the irregularly shaped flat plate. The barrier plate and the knife pad together separate the different irregularly shaped flat plates.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] 1. This device is equipped with a clamping mechanism. Through the cooperation of multiple end pads, a knife pad, long pressure plates, short pressure plates, and barrier plates with bolts one and two, it can quickly and accurately position irregularly shaped small flat workpieces and accurately position the processing range. Under the pressure of bolts one and two, the multiple long and short pressure plates form a vertically downward force to fix the irregularly shaped small flat workpieces, effectively avoiding workpiece displacement or vibration during processing, ensuring consistent processing quality, eliminating the need for repeated measurements with vernier calipers, and reducing human error.

[0020] 2. This device is equipped with a knife pad and a barrier plate. The knife pad and barrier plate are connected by bolt one, thereby locking different sides of the irregularly shaped flat plate. The barrier plate and the knife pad together separate different irregularly shaped flat plates, realizing the fixation of the irregularly shaped flat plate around its perimeter. This effectively avoids workpiece displacement or vibration during processing. It can firmly cooperate with long pressure plates and short pressure plates to clamp irregularly shaped flat plates, which helps to solve the problem of difficult positioning and clamping of small irregularly shaped flat plates. The modular long pressure plates, short pressure plates and other small pressure plates are linked with bolt one, bolt two and their nuts. Multi-directional fixation can be completed in a single operation, greatly shortening the clamping time. Attached Figure Description

[0033] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0034] This utility model discloses a fixing device for machining irregularly shaped flat CNC machine tools.

[0035] Reference Figure 1 , Figure 3The system includes a base plate 100, a clamping device 200, several bolts 400, several bolts 600, and several irregularly shaped flat plates 300. The irregularly shaped flat plates 300 include small irregularly shaped flat plates. Each irregularly shaped flat plate 300 is located between the base plate 100 and the clamping device 200. The clamping device 200 is movably connected to the top of the base plate 100 via corresponding bolts 400. The clamping device 200 includes a pad assembly 210, a pressure plate assembly 220, and several barrier plates 700. The pad assembly 210 is located between each irregularly shaped flat plate 300 and the base plate 100. The bottom of the pressure plate assembly 220 is connected via corresponding... Bolt 400 is snapped onto the top of the corresponding irregular plate 300. The top of the base plate 100 has several threaded holes 410 and several threaded grooves 450. Each bolt 400 is fixedly connected to the inside of the corresponding threaded hole 410. The clamping device 200 can generate an upward and downward squeezing force to fix the irregular plate 300. At the same time, the clamping device 200 is installed in a precise position, which can realize the rapid and accurate positioning of irregular small plate workpieces and accurately position the processing range. It can effectively avoid workpiece displacement or vibration during processing, ensure consistent processing quality, and reduce human error by eliminating the need for repeated measurement with vernier calipers.

[0036] Reference Figure 2 , Figure 3 The pad assembly 210 includes two end pads 211 and several knife pads 212. The two end pads 211 are located at the two ends of the top of the base plate 100, and the several knife pads 212 are divided into two groups. One group of knife pads 212 is located between the bottom inner side and the corresponding irregular plate 300, and the other group of knife pads 212 is located between the two corresponding irregular plates 300. The modular long pressure plate 221, short pressure plate 222 and other small pressure plates are linked with bolt 1 400, bolt 2 600 and their nuts. In a single operation, multiple irregular plates 300 in multiple directions can be fixed, which greatly shortens the clamping time.

[0037] Reference Figure 3The pressure plate assembly 220 includes several long pressure plates 221 and several short pressure plates 222. The long pressure plates 221 and short pressure plates 222 cooperate to apply pressure to the top of the irregularly shaped flat plate 300, forming a locking and fixing mechanism with the base plate 100 to prevent large displacement of the irregularly shaped flat plate 300 during processing. Each long pressure plate 221 and each short pressure plate 222 has three through holes 440. Each long pressure plate 221 and each short pressure plate 222 is located above the corresponding knife pad 212. One end of each long pressure plate 221 overlaps the top of the corresponding irregularly shaped flat plate 300, and the other end of each long pressure plate 221 is close to the base plate 100. At one end with a threaded groove 450, each short pressure plate 222 is located above the corresponding two knife pads 212. The short pressure plate 222 is fixed above the knife pad 212 by bolts 400. The height of the top of the knife pad 212 is lower than the height of the bottom of the short pressure plate 222. Only one or two threads of bolts 400 are needed to tighten the irregular plate 300 more securely. At the same time, only one or two threads of bolts 400 are needed to loosen the irregular plate 300 to push it out of the pressure range of the short pressure plate 222 and replace it with a new irregular plate 300. There is no need to unscrew all the bolts 400, which helps to save the clamping time of the clamping device 200.

[0038] Reference Figure 1 , Figure 7 One end of the bottom of each irregularly shaped plate 300 overlaps the top of the corresponding end pad 211. The top of each of the two end pads 211 is provided with eight through holes 420. After the bolts 400 are screwed into the eight through holes 420, the end pads 211 can be fixed on the base plate 100. At the same time, the head of the bolts 400 restricts the movement trajectory of the irregularly shaped plate 300, preventing the irregularly shaped plate 300 from detaching from the edge of the base plate 100.

[0039] Reference Figure 2 , Figure 3 Each of the several knife pads 212 has three stepped cylindrical holes 430 and two corner grooves 500 on its top. Due to the presence of the two corner grooves 500, the irregular plate 300 does not directly overlap with the base plate 100, thus facilitating drilling operations without worrying about damaging the base plate 100. At the same time, the bottom of the irregular plate 300 is not completely fitted with the corner groove 500, making it easy to push and finely adjust its position when placing the irregular plate 300. Also, even if it is squeezed excessively, the irregular plate 300 can be easily removed. Each corner groove 500 has a cylindrical through hole near the middle end. One end of the bottom of each irregular plate 300 overlaps with the inside of the corresponding corner groove 500. Some of the bolts 400 pass through the stepped cylindrical holes 430 and are threaded into the inside of the corresponding threaded holes 410. The top of some of the bolts 400 is engaged with the inside of the stepped cylindrical holes 430.

[0040] Reference Figure 5 , Figure 6 One portion of the bolts 400 penetrates the corresponding through hole 440 and the corresponding stepped cylindrical hole 430 and is threaded into the interior of the corresponding threaded hole 410. The top of one portion of the bolts 400 is engaged with the top of the corresponding long pressure plate 221 and the corresponding short pressure plate 222. The two irregularly shaped plates 300 are separated by the knife pad 212. Through the cooperation of a short pressure plate 222 and the bolts 400, pressure can be applied to the irregularly shaped plates 300 on both sides of the knife pad 212 at the same time. Thus, one short pressure plate 222 fixes two irregularly shaped plates 300 at a time, saving the number of short pressure plates 222 and improving the efficiency of clamping the irregularly shaped plates 300.

[0041] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 One portion of the bolts 400 penetrates the interior of the corresponding through hole 420 and is threaded into the interior of the corresponding threaded hole 410. The top of one portion of the bolts 400 is engaged with the top of the corresponding end pad 211. Each bolt 600 penetrates the interior of the corresponding through hole 440 and is threaded into the interior of the corresponding threaded groove 450. The bolt 600 is inserted into the through hole 440 of the long pressure plate 221. The bolts 400 penetrate the through hole 420 and are screwed into the threaded hole 410. The two points determine a straight line, so that the long pressure plate 221 determines the direction of pressure and prevents the long pressure plate 221 from rotating around the bolts 400 or 600, thereby better fixing and locking the irregular plate 300 in conjunction with the knife pad 212.

[0042] Reference Figure 1 , Figure 3 Several baffles 700 have an arc-shaped surface on one side. The baffles 700 are blocks with one side being an irregular arc shape. The baffles 700 cooperate with the knife pad 212 to surround the irregular flat plate 300 in the middle. The baffles 700, the end pads 211 and the knife pad 212 cooperate to surround the irregular flat plate 300 near the edge of the base plate 100. After the bolts 400 and 600 are screwed in, the long pressure plate 221 and the short pressure plate 222 squeeze the irregular flat plate 300 to form a vertical downward force, thereby completing the fixation and effectively preventing workpiece displacement or vibration during processing. One side of several baffles 700 is snapped onto one side of the corresponding irregular flat plate 300. The top of some of the bolts 400 is snapped onto the arc-shaped surface of the corresponding baffles 700. The end pads 211, the knife pad 212, the long pressure plate 221, the short pressure plate 222 and the baffles 700 all serve as positioning blocks.

[0043] The implementation principle of the fixing device for machining irregular flat CNC machine tools according to this utility model embodiment is as follows:

[0044] By using multiple end pads 211, knife pads 212, long pressure plates 221, short pressure plates 222, and barrier plates 700, along with bolts 400 and 600, the workpieces are quickly and accurately positioned, and the processing range is precisely defined. Under the pressure of bolts 400 and 600, the multiple long pressure plates 221 and short pressure plates 222 form a downward vertical force to fix the workpieces, effectively preventing workpiece displacement or vibration during processing, ensuring consistent processing quality, eliminating the need for repeated measurements with calipers, and reducing human error.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
