DETAILED DESCRIPTION

[0015] See also Figure 1-Figure 10 , a mechanical cutting processing equipment for ultra-deep cavities of precision molds, comprising a workbench 1 and a clamping device 2, the workbench 1 comprising a table 11, a plurality of support columns 12 are symmetrically fixedly connected to the bottom side surface of the table 11, and a pad 13 is fixedly connected to the bottom ends of the plurality of support columns 12; The clamping device 2 includes a first clamping plate 21 and a second clamping plate 22, and the first clamping plate 21 and the second clamping plate 22 are connected by two connecting mechanisms 23. The first limiting rods 211 are fixedly installed on both ends of the first clamping plate 21, and the second limiting rods 221 are fixedly installed on both ends of the second clamping plate 22. The connecting mechanism 23 includes a first connecting seat 231 and a second connecting seat 232. The first connecting seat 231 is fixedly connected to the table top 11, and the second connecting seat 232 is slidably connected to the table top 11. A first limiting groove 233 and a second limiting groove 234 are formed on the first connecting seat 231 and the second connecting seat 232. The first limiting groove 233 and the second limiting groove 234 are staggered in position. The two first limiting rods 211 are respectively slidably connected in the two first limiting grooves 233, and the two second limiting rods 221 are respectively It is slidably connected in the two second limit grooves 234, a double-end synchronous drive mechanism 3 is installed on the first connecting seat 231, and a closing component is installed on the first clamping plate 21, the closing component includes an empty groove 212 opened on the bottom side surface of the first clamping plate 21 and the first limit rod 211, and the first connecting seat 231 and the second connecting seat 232 are fixedly connected with a closing plate 213 on the side surface facing the empty groove 212, and the closing plate 213 is slidably connected in the empty groove 212, and the two first limit rods 211 are respectively slidably connected in a first limit groove 233 on the first connecting seat 231 and a first limit groove 233 on the second connecting seat 232, and the two second limit rods 221 are respectively slidably connected in a second limit groove 234 on the first connecting seat 231 and a second limit groove 234 on the second connecting seat 232.

[0016] When using the existing ultra-deep cavity mechanical cutting processing equipment for precision molds, it is necessary to first clamp and fix the mold material to be cut on the workbench, and then identify and locate the position of the mold material before controlling the tool to cut it. Since the existing clamping and fixing of the mold material usually requires clamping and fixing it in the horizontal and vertical directions, the waiting time is long, which reduces the overall processing efficiency, and a set of driving mechanisms needs to be set in each of the two directions; In order to solve the above problems, the present invention is provided with a clamping device 2 and a double-end synchronous driving mechanism 3. The first clamping plate 21, the second clamping plate 22 and the two connecting mechanisms 23 cooperate to enclose a rectangular placement groove in the middle for placing the mold raw material. With the help of the double-end synchronous driving mechanism 3, the first limiting rod 211 can be driven to move along the first limiting groove 233 to the side away from the first clamping plate 21 and the second limiting rod 221 can be driven to move along the second limiting groove 234 to the side away from the second clamping plate 22. The first limiting groove 233 on the first connecting seat 231 has a limiting effect on the first limiting rod 211 and the second limiting groove 234 has a limiting effect on the second limiting rod 221, so that the first clamping plate 21 and the second clamping plate 22 are close to each other. Since the first connecting seat 231 is fixedly connected to the table top 11 Therefore, as the first clamping plate 21 and the second clamping plate 22 approach each other, the placement groove will shrink toward the first connecting seat 231 until the inner side wall of the placement groove is finally attached to and pressed against the surrounding side walls of the mold material. The mold material placed in the placement groove is clamped and fixed with the help of the first clamping plate 21 and the second clamping plate 22. Because the double-end synchronous driving mechanism 3 can drive the first clamping plate 21 and the second clamping plate 22 at the same time, the time required for clamping and fixing can be significantly shortened, thereby improving the overall cutting processing efficiency, and only one set of driving mechanism needs to be set. Because the first connecting seat 231 is fixed on the table 11, after the clamping and fixing is completed, one end of the mold material will automatically be aligned with the first connecting seat 231, which can save the positioning process of the cutting tool before cutting, thereby further improving the processing efficiency.

[0017] like Figure 8 and Fig. 9 As shown, the double-end synchronous drive mechanism 3 includes two mounting plates 31, one end of the two mounting plates 31 close to the first connecting seat 231 is fixedly connected to the first limiting rod 211 and the second limiting rod 221 respectively, the two mounting plates 31 are perpendicular to each other, and a second transfer groove 32 is provided in one end of the mounting plate 31 away from the first connecting seat 231, and a second rotating shaft 33 penetrating the mounting plate 31 is rotatably connected on the inner surface of the second transfer groove 32, a sliding sleeve 34 is fixedly connected between the two second rotating shafts 33, and a transmission rod is slidably connected in the two sliding sleeves 34. 35, a first adapter ring 36 is fixedly connected to the transmission rod 35, a first adapter groove 235 is opened on the first connecting seat 231, a first rotating shaft 236 is rotatably connected in the first adapter groove 235, a second adapter ring 37 is fixedly connected to the first rotating shaft 236, a multi-stage electric telescopic rod 38 is fixedly installed on the outer surface of the second adapter ring 37, a fixing frame 39 is fixedly connected to the output end of the multi-stage electric telescopic rod 38, a third rotating shaft 391 is rotatably connected in the fixing frame 39, and the third rotating shaft 391 is fixedly connected to the first adapter ring 36.

[0018] As for how the double-end synchronous driving mechanism 3 can simultaneously drive the first clamping plate 21 and the second clamping plate 22, its working principle is that since the two mounting plates 31 are respectively fixedly connected to the first limiting rod 211 and the second limiting rod 221, the two mounting plates 31 can only move in the horizontal and longitudinal directions due to the limiting effect of the connecting mechanism 23 on the first limiting rod 211 and the second limiting rod 221, and the transmission rod 35 and the mounting plate 31 are rotatably connected through the second transfer groove 32, the second rotating shaft 33 and the sliding sleeve 34. The electric telescopic rod 38 and the first connecting seat 231 are also rotatably connected through the first adapter groove 235, the first rotating shaft 236 and the second adapter ring 37. The transmission rod 35 and the multi-stage electric telescopic rod 38 are rotatably connected through the first adapter ring 36, the fixing frame 39 and the third rotating shaft 391. With the cooperation of the above-mentioned rotatable connection, the entire double-end synchronous drive mechanism 3 forms a connecting rod structure. Based on the principle of composition and decomposition of motion, the connecting rod structure can be used to extend or shorten the multi-stage electric telescopic rod 38. The telescopic movement of the telescopic rod 38 is converted into the lateral movement and longitudinal movement of the two mounting plates 31 through the transmission of the connecting rod structure, that is, the telescopic movement of the multi-stage electric telescopic rod 38 is decomposed into the lateral movement and longitudinal movement of the two mounting plates 31 during the transmission process through the connecting rod structure, so that the multi-stage electric telescopic rod 38 can simultaneously drive the first clamping plate 21 and the second clamping plate 22 to move, and because the multi-stage electric telescopic rod 38 can rotate around the first rotating shaft 236, in the process of driving the first clamping plate 21 and the second clamping plate 22 to move and clamp and fix the mold raw material, the side wall of the mold raw material is used as feedback. When one of the first clamping plate 21 and the second clamping plate 22 completes the clamping of the mold raw material first, it stops moving due to the obstruction of the mold raw material. Thereafter, the connecting rod structure will adaptively adjust the angle of the multi-stage electric telescopic rod 38, so that the subsequent extension movement of the multi-stage electric telescopic rod 38 is completely distributed and converted to the clamping in another direction, thereby expanding the scope of application of the present invention so that it can be applied to mold raw materials of various sizes.

[0019] like Figure 2 and Fig.10 As shown, a waste chip shielding device 4 is installed on the outer side of the workbench 1, and the waste chip shielding device 4 includes an outer mounting frame 41, and the outer mounting frame 41 is fixedly connected to the upper surface of the pad 13, and an inner baffle plate 42 is slidably connected to the outer surface of the table top 11, and a slot 43 matching the first connecting seat 231 is opened on the inner baffle plate 42, and the first connecting seat 231 is slidably connected to the inner surface of the slot 43, and a fixed baffle plate 431 matching the slot 43 is installed on the first connecting seat 231.

[0020] Based on the characteristics of the clamping and fixing method adopted by the present invention, after the mold raw material is clamped and fixed, the first clamping plate 21 and the second clamping plate 22 are tightly attached to the outer surface of the mold raw material. On this basis, by arranging a waste chip shielding device 4 on the outer side of the workbench 1, with the help of the shielding effect of the inner baffle plate 42, the waste chips flying around generated during the cutting process can be blocked and restricted between the outer side of the clamping device 2 and the inner side of the waste chip shielding device 4. The advantage of such a setting is that after the cutting process is completed, the multi-stage electric telescopic rod 38 in the double-end synchronous drive mechanism 3 is controlled to shorten, and the first clamping plate 21 and the second clamping plate 22 in the clamping device 2 are driven to move and reset. The movement of the first clamping plate 21 and the second clamping plate 22 during the resetting process can be used to push the waste chips that fall on the table 11 due to being blocked to the outside, and pile them together in an "L" shape for subsequent unified cleaning.

[0021] like Figure 4 and Figure 5 As shown, an automatic lifting component is installed between the clamping device 2 and the waste chip shielding device 4, and the automatic lifting component includes a first groove 44 and a second groove 45 opened on the two inner surfaces of the inner baffle plate 42. The inner baffle plate 42 is slidably connected to the inner surface of the outer mounting frame 41, and one end of the second limiting rod 221 facing the first groove 44 and one end of the first limiting rod 211 facing the second groove 45 are fixedly connected with a boss 46, and the two bosses 46 are slidably connected in the first groove 44 and the second groove 45 respectively.

[0022] The automatic lifting component can utilize the movement of the first clamping plate 21 and the second clamping plate 22 in the process of clamping and fixing the mold raw material to drive the two bosses 46 to move in the first groove 44 and the second groove 45 respectively, and utilize the extrusion of the bosses 46 and the inclined side walls in the first groove 44 and the second groove 45 to produce an upward lifting effect on the inner baffle plate 42, thereby driving the inner baffle plate 42 to automatically rise, so as to prevent waste chips from splashing onto the ground during the subsequent cutting process. After the cutting process is completed, when the double-end synchronous drive mechanism 3 drives the clamping device 2 to reset, the inner baffle plate 42 can be driven to automatically descend and reset by virtue of its own gravity, so that the staff can conveniently take out the mold raw material after processing.

[0023] like Figure 3 As shown, a waste chip collecting device 5 is installed between the workbench 1 and the waste chip shielding device 4, and the waste chip collecting device 5 includes a collecting bin 51, and the collecting bin 51 is fixedly connected to two adjacent outer surfaces of the table top 11, and the outer surface of the collecting bin 51 is slidably connected to the inner surface of the inner baffle 42, and a filter screen 52 is fixedly installed in the collecting bin 51, and a storage tank 53 is fixedly installed on the bottom end of the collecting bin 51.

[0024] By setting up a waste chip collection device 5, it can cooperate with the waste chip shielding device 4. In the process of driving the first clamping plate 21 and the second clamping plate 22 in the clamping device 2 to move and reset through the double-end synchronous driving mechanism 3, the waste chips that fall onto the table 11 due to being blocked can be pushed into the collection bin 51 by means of the movement of the first clamping plate 21 and the second clamping plate 22 during the resetting process, thereby completing the collection of waste chips and facilitating subsequent cleaning. The setting of the filter screen 52 and the storage tank 53 can complete the filtering and separation of waste chips and coolant. The filtered coolant is stored in the storage tank 53 for recycling.

[0025] like Figure 5 As shown, a waste chip processing device 6 is installed between the clamping device 2 and the waste chip collection device 5, and the waste chip processing device 6 includes two groups of side plates 61. The two groups of side plates 6 are grouped in pairs, and the two groups of side plates 61 are respectively fixedly connected to one end of the first limiting rod 211 close to the second groove 45 and one end of the second limiting rod 221 close to the first groove 44. A fixed shaft is fixedly connected between the two side plates 61 of each group, and a third adapter ring 62 is rotatably connected to the fixed shaft. A scraper 63 is installed on the outer surface of the third adapter ring 62, and the scraper 63 is slidably connected in the collection bin 51. The scraper 63 is inclined, and a torsion spring 64 is fixedly connected between the two side surfaces of the third adapter ring 62 and the side plates 61.

[0026] By setting up a waste processing device 6, with the help of the movement of the first clamping plate 21 and the second clamping plate 22 during the clamping and resetting process, the side plate 61 is driven to move together through the first limit rod 211 and the second limit rod 221, and then the scraper 63 is driven to move in the collecting bin 51. Since the scraper 63 is arranged at an angle and a torsion spring 64 is installed between the third adapter ring 62 and the side plate 61, the elastic force of the torsion spring 64 can be used to gather the waste on the filter screen 52 in one direction with the help of the movement of the scraper 63 during the resetting process of the clamping device 2 for subsequent cleaning.

[0027] In the present invention, the mold raw material is first placed in a placement groove surrounded by the first clamping plate 21, the second clamping plate 22 and the two connecting mechanisms 23, and then the multi-stage electric telescopic rod 38 is started and controlled to extend, and the output end of the multi-stage electric telescopic rod 38 drives the transmission rod 35 to move through the fixed frame 39, the third rotating shaft 391 and the first adapter ring 36, and the transmission rod 35 then drives the first limiting rod 211 and the second limiting rod 221 to move longitudinally and transversely respectively through the sliding sleeve 34, the second rotating shaft 33, the second adapter groove 32 and the two mounting plates 31, so that the first clamping plate 21 and the second clamping plate 22 are close to each other. Since the first connecting seat 231 is fixedly connected to the table 11, as the first clamping plate 21 and the second clamping plate 22 are close to each other , the placement groove will shrink toward the first connecting seat 231 until the inner side wall of the placement groove is finally attached to and pressed against the surrounding side walls of the mold raw material, and the mold raw material placed in the placement groove is clamped and fixed by means of the first clamping plate 21 and the second clamping plate 22. Because the double-end synchronous driving mechanism 3 can drive the first clamping plate 21 and the second clamping plate 22 at the same time, the time required for clamping and fixing can be significantly shortened, thereby improving the overall cutting efficiency, and only one set of driving mechanism is required. Because the first connecting seat 231 is fixed on the table 11, after the clamping and fixing is completed, one end of the mold raw material will automatically align with the first connecting seat 231, which can save the positioning process of the cutting tool before cutting, thereby further improving the processing efficiency; Because the multi-stage electric telescopic rod 38 can rotate around the first rotating shaft 236, when the first clamping plate 21 and the second clamping plate 22 are driven to move and clamp the mold material, the side wall of the mold material is used as feedback. When one of the first clamping plate 21 and the second clamping plate 22 first completes clamping the mold material, it stops moving due to the obstruction of the mold material. After that, the connecting rod structure will adaptively adjust the angle of the multi-stage electric telescopic rod 38, so that the subsequent extension movement of the multi-stage electric telescopic rod 38 is fully distributed and converted to clamping in another direction, thereby expanding the scope of application of the present invention and making it applicable to mold materials of various sizes. By means of the movement of the first clamping plate 21 and the second clamping plate 22 in the process of clamping and fixing the mold raw material, the two protrusions 46 can be driven to move in the first groove 44 and the second groove 45 respectively, and the inner baffle plate 42 is pushed upward by the extrusion of the protrusions 46 and the inclined side walls in the first groove 44 and the second groove 45, thereby driving the inner baffle plate 42 to automatically rise, so as to prevent waste chips from splashing onto the ground during the subsequent cutting process. After the cutting process is completed, the multi-stage electric telescopic rod 38 is controlled to shorten and drive the clamping device 2 to reset. By means of the gravity of the inner baffle plate 42 itself, the inner baffle plate 42 is driven to automatically descend and reset, so that the staff can conveniently take out the mold raw material after processing; In the process of driving the first clamping plate 21 and the second clamping plate 22 in the clamping device 2 to move and reset through the double-end synchronous driving mechanism 3, the waste debris that is blocked and falls on the table 11 can be pushed into the collecting bin 51 with the help of the movement of the first clamping plate 21 and the second clamping plate 22 during the resetting process. At the same time, the side plate 61 is driven to move together through the first limit rod 211 and the second limit rod 221, and then the scraper 63 is driven to move in the collecting bin 51. Since the scraper 63 is arranged at an angle and a torsion spring 64 is installed between the third adapter ring 62 and the side plate 61, the elastic force of the torsion spring 64 can be used. During the resetting process of the clamping device 2, with the help of the movement of the scraper 63, the waste debris on the filter screen 52 can be gathered in one direction for subsequent cleaning.
