As shown in fig. 3, in the present embodiment, the clamping tightening screw 540 is provided with a tightening knob 541.
As shown in fig. 4 and 5, in the present embodiment, the fixed clamp 520 has a first clamping surface 521, and the second movable block 532 has a second clamping surface 537; the first clamping surface 521 is disposed opposite to the second clamping surface 537.
The working principle of the numerical control machining center 10 with the elastic clamping fixture is described below (please refer to fig. 1 to 5 together):
before processing the workpiece, the tightening knob 541 is rotated in a forward direction (the "forward direction" and the "reverse direction" are only opposite directions), so that the first movable block 531 drives the second movable block 532 to move away from the fixed clamping device 520; the workpiece is then placed between the first clamping surface 521 and the second clamping surface 537; then, the tightening knob 541 is rotated reversely, at this time, the first movable block 531 pushes the second movable block 532 to slide toward the direction close to the fixing clip 520 until the first clamping surface 521 and the second clamping surface 537 clamp the workpiece; when the clamping tightness of the workpiece needs to be further adjusted, the knob is further rotated to enable the first movable piece to slide towards the direction close to the second movable block 532 or away from the second movable block 532, so that the clamping tightness of the workpiece is adjusted; that is, the clamping of the fixed clamping piece 520 and the second movable block 532 to the workpiece belongs to flexible clamping;
the workpiece is elastically clamped, so that the workpiece is stably clamped and cannot be clamped too tightly; the processing fraction defective of the workpiece is reduced, and the processing efficiency of the workpiece is improved;
the adjusting spring 533 is disposed in the accommodating groove 535, and the other end of the guiding column 534 extends into the accommodating groove 535 and is connected with the adjusting spring 533; the design enables the first movable block 531 and the second movable block 532 to keep stable position relation in the horizontal transverse direction, so that the second movable block 532 can be ensured to stably move along the horizontal longitudinal direction without deflection in the horizontal longitudinal direction, stable clamping of the workpiece is ensured, and high-precision machining of the workpiece is ensured;
after the workpiece is clamped, inputting relevant information and processing parameters of the workpiece on the touch display screen 30; the control system outputs corresponding control instructions to the elastic clamping jig 50 and the processing tool bit system 40 after performing operation processing according to the information input by the touch display screen 30; the elastic clamping jig 50 adjusts the position of the workpiece according to the control instruction, and the machining tool bit system 40 machines the workpiece according to the control instruction;
specifically, the horizontal longitudinal translation mechanism 570 drives the movable base 560 to move in the horizontal longitudinal direction along the fixed base 550 according to the control instruction; the horizontal transverse translation mechanism 580 drives the elastic clamping mechanism 60 to move in the horizontal transverse direction along the movable base 560 according to the control instruction; therefore, the two-dimensional driving of the elastic clamping mechanism 60 on the horizontal plane is realized, so that the two-dimensional driving of the workpiece on the horizontal plane is realized, and the workpiece can accurately reach the corresponding horizontal plane position for processing;
after the workpiece is machined, the tightening knob 541 is rotated again, so that the first movable block 531 moves along the movable base 560 in a direction away from the fixed clamping member 520, and the second movable block 532 is driven to move in a direction away from the fixed clamping member 520, thereby loosening the workpiece; after the fixed clamping piece 520 and the second movable block 532 loosen the workpiece, the workpiece can be taken down from the elastic clamping jig 50, and a next workpiece to be processed is reloaded;
the matching design of the guide rail 511 and the clamping guide groove 536 ensures that the first movable block 531 stably slides along the clamping base 510 without deflection, thereby ensuring stable clamping of the workpiece.
Although the numerical control machining center 10 with the elastic clamping jig realizes elastic clamping on the workpiece, the elastic clamping ensures stable clamping on the workpiece and simultaneously cannot clamp the workpiece too tightly; however, when a specific control command is issued by the nc machining center 10, the command is input through the touch display 30, and the machining state of the workpiece and the state information of the nc machining center 10 itself are displayed in real time through the touch display 30. Therefore, whether the touch display screen 30 works normally or not directly affects whether the numerical control machining center can work normally or not.
However, the touch display screen 30 is exposed to the air in the workshop, and a large amount of dust and debris generated in the processing process are mixed in the air in the workshop; dust and debris are easily deposited on the touch display screen 30; moreover, the touch display screen 30 is easily scratched, and has no good waterproof effect. In order to better protect the touch display screen 30, the touch display screen 30 needs to be covered when the digital control processing center 10 is not in use, so that the touch display screen 30 is ensured not to be exposed in the air of a workshop any more, and therefore the effects of dust prevention, scratch prevention and water prevention are achieved on the touch display screen 30, and the touch display screen 30 is effectively protected.
As shown in fig. 1, the numerical control machining center 10 with the elastic clamping fixture of the present invention further includes a protection outer frame 70 and a protection panel 80. The touch display screen 30 is nested and installed on the upper portion of the protective outer frame 70. The protection panel 80 is matched with the protection outer frame 70, and when the numerical control machining center 10 operates, the protection panel 80 is opened by sliding downwards; when the numerical control machining center 10 is idle, the protection panel 80 slides up and covers the touch display screen 30, so that the touch display screen 30 is prevented from being exposed in the air of a workshop, the effects of dust prevention, scratch prevention and water prevention are achieved, and the touch display screen 30 is effectively protected.
As shown in fig. 1, the protective frame 70 is divided into an upper portion and a lower portion, the touch display screen 30 is nested and mounted on the upper portion of the protective frame 70, the protective panel 80 slides along the protective frame 70, and when the protective panel 80 slides to the upper portion of the protective frame 70, the protective panel 80 covers the touch display screen 30 to protect the touch display screen 30; when the protection panel 80 slides down to the lower portion of the protection frame 70, the touch display screen 30 is exposed.
In order to protect the touch display screen 30, when the numerical control machining center 10 is in an idle state, the protection panel 80 needs to cover the touch display screen 30 to protect the touch display screen 30. However, in practical applications, it is difficult to avoid the situation that the touch display screen 30 is exposed in the air of a workshop when a non-worker opens the protection panel 80; or the worker may open the protection panel 80 that should be in the closed state due to the misoperation, so that the touch display screen 30 is exposed in the workshop air. In order to avoid that a non-operator who is not familiar with the nc processing center 10 easily opens the protection panel 80 or that an operator mistakenly opens the protection panel 80, the present invention provides the following designs for the structures of the protection panel 80 and the protection frame 70, and the cooperation of the protection panel 80 and the protection frame 70:
as shown in fig. 6 and 7, a cylindrical guide post 100 is provided at a lower portion of the protection frame 70, and a cover return spring 200 is sleeved on the cylindrical guide post 100. The bottom surface of the protection panel 80 is provided with a through hole 300, and the protection panel 80 is slidably coupled to the cylindrical guide post 100 through the through hole 300.
As shown in fig. 8 and 9, the first and second balance springs 400 and 500 are symmetrically disposed on the bottom surface of the protection panel 80 around the through hole 300. The first balance spring 400 and the second balance spring 500 are both V-shaped. The first balance spring 400 comprises a first abutting portion 401 and a first clamping portion 402; the second balance spring 500 includes a second supporting portion 501 and a second engaging portion 502.
As shown in fig. 8, 9 and 10, the lower portion of the protection frame 70 has a support base plate 600, and the support base plate 600 is provided with a first covering maintaining protrusion 700 and a second covering maintaining protrusion 800 at two sides of the cylindrical guide column 100; the first covering maintaining protrusion 700 and the second covering maintaining protrusion 800 are staggered in height on the supporting base plate 600; the first abutting portion 401 of the first balance resilient piece 400 abuts against or is separated from the first covering maintaining bump 700; the second abutting portion 501 of the second balance resilient piece 500 abuts against or separates from the second covering and maintaining bump 800.
As shown in fig. 8, 9 and 10, the supporting base plate 600 is provided with a cover-closing prevention clamping groove 900, and the positions of the cover-closing prevention clamping groove 900 on the supporting base plate 600 are lower than the position of the first cover-closing maintaining bump 700 and the position of the second cover-closing maintaining bump 800; the first clamping portion 402 abuts against the supporting bottom plate 600 or is separated from the supporting bottom plate 600 or is clamped into the cover-closing-preventing clamping groove 900; the second engaging portion 502 is abutted against the supporting base plate 600 or separated from the supporting base plate 600.
As shown in fig. 10, in the present embodiment, a first vertical blocking surface 710 is disposed on a side of the first covering and maintaining bump 700 close to the touch display screen 30; a second vertical blocking surface 810 is arranged on one side, close to the touch display screen 30, of the second covering and maintaining bump 800; the first vertical blocking face 710 and the second vertical blocking face 810 are perpendicular to the support base 600.
As shown in fig. 9, in the present embodiment, a first arc-shaped guiding surface 720 is disposed on a side of the first covering maintaining protrusion 700 away from the touch display screen 30; a second arc-shaped guide surface 820 is disposed on a side of the second cover maintaining protrusion 800 away from the touch display screen 30.
As shown in fig. 8, in the present embodiment, the number of the cover-closing prevention clamping grooves 900 is plural, and the plural cover-closing prevention clamping grooves 900 form a multi-stage cover-closing prevention reset restriction.
The operation principle of opening and closing the protection panel 80 will be described below (see fig. 1, 6 to 12):
when the protection panel 80 covers the touch display screen 30 (as an initial covering state); at this time, the first clip portion 402 of the first balance resilient sheet 400 and the second clip portion 502 of the second balance resilient sheet 500 both abut against the support base plate 600, and the first balance resilient sheet 400 and the second balance resilient sheet 500 provide a balanced support force for the protection panel 80, so that the protection panel 80 is parallel to the support base plate 600; in addition, the first abutting portion 401 of the first balance resilient tab 400 abuts against the first vertical blocking surface 710 of the first lid maintaining protrusion 700; at this time, the cover return spring 200 provides an elastic force to the protection panel 80, so that the protection panel 80 is stably maintained right above the touch display screen 30; the first abutting part 401 abuts against the first vertical blocking face 710 and covers the reset spring 200 together, so that the touch display screen 30 is stably covered right above the touch display screen 30, and a stable covering effect is formed on the touch display screen 30;
if the protection panel 80 slides downwards directly, the protection panel 80 cannot slide downwards smoothly because the first abutting portion 401 of the first balance spring 400 abuts against the first vertical blocking surface 710 of the first covering and maintaining bump 700;
if the protection panel 80 is opened to expose the touch display screen 30, the protection panel 80 is pressed to a side close to the second covering and maintaining bump 800; in this process, the protection panel 80 rotates forward (the forward direction is opposite to the reverse direction) around the cylindrical guide post 100, so that the side of the protection panel 80 close to the second cover maintaining protrusion 800 sinks and the side close to the first cover maintaining protrusion 700 tilts upward; in the process that one side of the protection panel 80 close to the first covering maintaining bump 700 is tilted upwards, the first balance elastic sheet 400 is tilted upwards along with the protection panel 80, so that the first abutting part 401 is finally separated from the first vertical blocking surface 710;
when the first abutting portion 401 is separated from the first vertical blocking surface 710, the protection panel 80 slides down in the current posture until the second abutting portion 501 abuts against the second vertical blocking surface 810; at this time, the protection panel 80 cannot slide down continuously in the current posture; therefore, it is necessary to stop pressing the side of the protection panel 80 close to the second closure maintaining protrusion 800 and to press the side of the protection panel 80 close to the first closure maintaining protrusion 700; in this process, the protection panel 80 reversely rotates around the cylindrical guide post 100 as a central axis, so that one side of the protection panel 80 close to the second covering maintaining protrusion 800 is tilted upward and one side close to the first covering maintaining protrusion 700 is sunk; in the process that one side of the protection panel 80 close to the second covering and maintaining bump 800 is upwarped, the second balance elastic sheet 500 is continuously upwarped along with the protection panel 80, so that the second abutting portion 501 is finally separated from the second vertical blocking surface 810;
when the second abutting portion 501 is separated from the second vertical blocking surface 810, the protection panel 80 continues to slide downwards in the current posture; in the process that the protection panel 80 slides down, the covering return spring 200 is continuously compressed and accumulates elastic potential energy;
when the first balance spring 400 goes over at least one cover-closing prevention clamping groove 900, the protection panel 80 can be released, so that the protection panel 80 enters and is kept in an open state (at this time, the protection panel 80 is in an inclined state, namely is not parallel to the support base plate 600); specifically, at the moment of releasing the protection panel 80, the cover return spring 200 provides an elastic restoring force for the protection panel 80 to return to the direction close to the touch display screen 30 at a time, so that the protection panel 80 has a tendency of returning to the cover direction close to the touch display screen 30; meanwhile, on one hand, the first balance spring 400 is stretched due to the elastic force of the first balance spring and the first clamping portion 402 of the first balance spring is firmly clamped in one of the anti-cover clamping grooves 900; on the other hand, the elastic force of the second balance elastic sheet 500 acts to jack up the side, close to the second balance elastic sheet 500, of the protection panel 80, so that the protection panel 80 further rotates reversely, and the first clamping portion 402 is further firmly clamped in one of the cover-closing-preventing clamping grooves 900; in short, the cooperation of the cover return spring 200, the cylindrical guide post 100 and the through hole 300, the cooperation of the first balance spring 400 and the cover-closing-preventing clamping groove 900, and the elastic force of the second balance spring 500 cooperate with each other to firmly clamp the first clamping portion 402 in one of the cover-closing-preventing clamping grooves 900, so that the protection panel 80 is stably kept in the current opening state, and the touch display screen 30 is stably exposed;
to sum up, when the protection panel 80 is opened, a worker needs to press one side of the protection panel 80 first, then slide down the protection panel 80 for a certain distance, and then press the other side of the protection panel 80 and then slide down the protection panel 80 continuously; when the protection panel 80 slides down to the right position, the hand can be released; through a multi-step accurate operation mode, the phenomenon that the touch display screen 30 is exposed when the protective panel 80 is opened due to misoperation is effectively avoided, and meanwhile, the phenomenon that the touch display screen 30 in an idle state is easily opened by non-working personnel is prevented from being exposed;
when the touch display screen 30 needs to be covered, the protection panel 80 needs to be pressed to a side close to the second covering maintaining bump 800; in this process, the protection panel 80 rotates forward around the cylindrical guide post 100 as a central axis, so that one side of the protection panel 80 close to the second locking maintaining protrusion 800 sinks and one side close to the first locking maintaining protrusion 700 tilts upward; in the process that one side of the protection panel 80 close to the first covering maintaining bump 700 is upwarped, the first balance elastic sheet 400 is continuously upwarped along with the protection panel 80, so that the first clamping portion 402 is finally separated from the covering-prevention clamping groove 900;
when the first clamping portion 402 is separated from the cover-locking clamping grooves 900, the protection panel 80 is slid a certain distance in the current posture until the first clamping portion 402 is separated from the upper side of the cover-locking clamping grooves 900; at this time, the protection panel 80 is released, and on one hand, the protection panel 80 automatically rotates in the opposite direction under the elastic force of the first balancing elastic sheet 400 and the second balancing elastic sheet 500 until the protection panel 80 is parallel to the support base plate 600; on the other hand, the protection panel 80 automatically resets to a direction close to the touch display screen 30 under the action of the elastic restoring force of the cover reset spring 200 and finally covers the touch display screen 30 in parallel;
it should be further noted that, in the process of sliding the protection panel 80 onto the touch display screen 30 for resetting, the second balance elastic piece 500 and the first balance elastic piece 400 smoothly pass through the second covering maintaining bump 800 and the first covering maintaining bump 700 respectively;
when the second clamping portion 502 abuts against the second arc-shaped guiding surface 820, the protection panel 80 has a tendency of returning to a direction close to the touch display screen 30 under the action of the elastic restoring force of the reset spring 200, so that the second arc-shaped guiding surface 820 has an upward acting force on the second clamping portion 502; under the uplifting action force of the second arc-shaped guide surface 820, the protection panel 80 reversely rotates by taking the cylindrical guide column 100 as a central shaft; when the protection panel 80 rotates reversely, the second catching portion 502 gradually separates from the second arc-shaped guide surface 820, so that the second balance resilient piece 500 smoothly goes over the second covering maintaining protrusion 800;
after the second balancing elastic sheet 500 passes over the second covering and maintaining bump 800, the protection panel 80 is restored to be parallel to the support base plate 600 again under the action of the first balancing elastic sheet 400 and the second balancing elastic sheet 500, and continues to slide upwards in a state parallel to the support base plate 600 until the first clamping portion 402 abuts against the first arc-shaped guide surface 720;
the principle that the first balance spring 400 passes over the first covering and maintaining bump 700 is the same as the principle that the second balance spring 500 passes over the second covering and maintaining bump 800, and the description is omitted; after the first balance resilient sheet 400 passes over the first covering and maintaining bump 700, the protection panel 80 is restored to be parallel to the support base plate 600 again under the action of the first balance resilient sheet 400 and the second balance resilient sheet 500; at this time, the protection panel 80 remains covering the touch display screen 30;
in summary, the self-resetting of the protection panel 80 needs to be realized by the mutual cooperation of the first arc-shaped guide surface 720 of the first covering and maintaining projection 700, the second arc-shaped guide surface 820 of the second covering and maintaining projection 800, the first balance spring sheet 400, the second balance spring sheet 500, the protection panel 80, the covering and resetting spring 200 and the cylindrical guide column 100, and the structural components do not work independently;
in short, when the protection panel 80 is closed, the worker needs to press one side of the protection panel 80 close to the second closing maintaining protrusion 800, slide the protection panel 80 upward for a certain distance, and then release the protection panel 80, so that the protection panel 80 can slide upward and reset smoothly; through a multi-step accurate operation mode, the protection panel 80 is effectively prevented from being closed due to misoperation, and meanwhile, the touch display screen 30 in work is prevented from being easily closed by non-working personnel;
in the invention, the opening and closing of the protection panel 80 can be accurately, smoothly and quickly realized only by applying certain attention to the working personnel familiar with the numerical control machining center 10; due to the design, the touch display screen 30 is effectively prevented from being opened or closed by non-workers at will, and meanwhile, misoperation of the workers is also effectively avoided; the invention has certain complexity to the operation of opening and closing the touch display screen 30 to prevent other people from operating randomly and misoperation, but does not influence the normal production efficiency due to too complicated operation, namely, a proper balance point is found between the complexity and the simplicity;
the plurality of anti-cover-closing clamping grooves 900 are arranged, so that multi-stage anti-cover-closing reset limitation is formed, and clamping can be realized without strictly and accurately aligning the first abutting part 401 of the first balance elastic sheet 400 with the anti-cover-closing clamping grooves 900 when the protection panel 80 slides downwards; that is, the protection panel 80 does not need to slide down very accurately, and the protection panel 80 only needs to slide down to the position above the area formed by the first balance shrapnel 400 and the plurality of anti-cover-closing clamping grooves 900, so that the operation is more convenient and efficient;
here, the functions of the first and second balance springs 400 and 500 will be further described:
the first balance spring 400 functions as follows:
in one aspect, the first balancing resilient tab 400 is engaged with the second balancing resilient tab 500, so that the protection panel 80 is balanced (i.e. parallel to the support base 600) when in the closed state or the open state; at this time, the first and second balancing resilient tabs 400 and 500 stably abut against the supporting base plate 600 under the action of the elastic force, and since the first and second balancing resilient tabs 400 and 500 have the same structure and are symmetrically arranged, the supporting effect of the first and second balancing resilient tabs 400 and 500 on the protection panel 80 is symmetrical, thereby ensuring that the protection panel 80 is balanced;
on the other hand, when the protection panel 80 is kept in the open state, the first clamping portion 402 of the first balance elastic sheet 400 is clamped into the cover-closing-prevention clamping groove 900, so that the protection panel 80 is prevented from automatically returning to the cover-closing state;
on the other hand, the V-shaped structure of the first balance spring 400 makes the first abutting portion 401 firmly abut against the first vertical blocking surface 710; when the cover is closed and reset, the first clamping portion 402 abuts against the first arc-shaped guide surface 720; the first clamping portion 402 generates elastic deformation in the process of abutting against the first arc-shaped guide surface 720 and combines the guiding function of the first arc-shaped guide surface 720, so that the first balance elastic sheet 400 smoothly passes through the first covering maintaining bump 700;
the second balance dome 500 functions as:
in one aspect, the second balancing resilient piece 500 is engaged with the first balancing resilient piece 400, so that the protection panel 80 is balanced (i.e. parallel to the support base 600) when in the closed state or the open state; at this time, the second balancing resilient tab 500 and the first balancing resilient tab 400 stably abut against the supporting base plate 600 under the action of elastic force, and since the second balancing resilient tab 500 has the same structure as the first balancing resilient tab 400 and is symmetrically disposed, the supporting effect of the second balancing resilient tab 500 and the first balancing resilient tab 400 on the protection panel 80 is symmetrical, thereby ensuring that the protection panel 80 is balanced;
on the other hand, the V-shaped structure of the second balance elastic piece 500 enables the second abutting portion 501 to firmly abut against the second vertical blocking surface 810; when the cover is closed and reset, the second clamping portion 502 abuts against the second arc-shaped guide surface 820; the second clamping portion 502 generates elastic deformation in the process of abutting against the second arc-shaped guiding surface 820 and combines with the guiding function of the second arc-shaped guiding surface 820, so that the second balance elastic piece 500 smoothly crosses the second cover maintaining bump 800.
