As shown in fig. 5, in the present embodiment, the universal driving assembly 430 includes a cylinder 431 and a connecting rod 432, and one end of the connecting rod 432 is drivingly connected to the cylinder 431. The other end of the connecting rod 432 is provided with a universal ball head 433, the bottom surface of the processing platform 410 is provided with an arc-shaped groove (not shown), and the universal ball head 433 of the connecting rod 432 is rotatably accommodated in the arc-shaped groove.

As shown in FIG. 5, in this embodiment, there are multiple sets of gimbal drive assemblies 430. The plurality of sets of gimbal drive assemblies 430 are distributed in an annular array centered on a central axis of the processing platform 410.

As shown in fig. 2, 3 and 4, in the present embodiment, the debris collecting device 50 includes a debris collecting bucket 510 and a fan (not shown), the fan is disposed at the rear end of the debris collecting bucket 510; the rear end of the debris collection hopper 510 communicates with a debris collection frame (not shown). The processing platform 410 is disposed in a debris collection bucket 510.

As shown in fig. 2, in the present embodiment, a filter screen 520 is provided at the bottom of the debris collection hopper 510.

The operation of the numerically controlled grinding apparatus 10 with debris collection function is described below (see also fig. 1 to 5):

before the part is ground and machined, the part is placed on the top surface of the machining platform 410, and the plurality of clamping pieces 421 respectively slide towards the center of the machining platform 410 along the guide grooves 411, so that the plurality of clamping pieces 421 are close to each other and finally respectively contact with the part, and the part is stably clamped;

inputting relevant information and corresponding processing parameters of the part to be processed on the touch display screen 30; the touch display screen 30 transmits the received related information and the processing parameters to the control device, and the control device outputs corresponding control instructions to the polishing device 40 according to the received related information and the processing parameters so as to precisely control the polishing tool head 450 to polish the parts; the horizontal traversing driving assembly 461 indirectly drives the grinding cutter head 450 to reciprocate along the horizontal traversing direction, the horizontal vertical moving driving assembly 462 indirectly drives the grinding cutter head 450 to reciprocate along the horizontal vertical moving direction, and the longitudinal vertical moving driving assembly 463 indirectly drives the grinding cutter head 450 to reciprocate along the longitudinal vertical moving direction, so that the grinding cutter head 450 can move in the three-dimensional direction, and multi-direction high-precision grinding processing of parts is realized;

during the process of grinding the part by the grinding cutter head 450, the fan continuously works and continuously absorbs grinding debris of the debris collecting hopper 510 into the debris collecting frame; the scraps generated by the grinding of the parts by the grinding tool head 450 can be sucked into the scrap collecting frame, so that the scraps generated by grinding cannot float in the air, and a clean and safe working environment is provided for workers; it should be noted that, by arranging the filter screen 520 at the bottom of the debris collection hopper 510, the filter screen 520 blocks the excessive debris, so as to prevent the grinding debris with excessive volume from entering the fan and affecting the normal operation of the fan; if the debris with larger volume enters the debris collection frame through the fan, the debris is easy to collide with the fan blades of the fan when passing through the fan; when larger debris collides with the fan blades, the fan blades are easy to be broken, and on the other hand, the debris is easy to be ejected due to the collision, so that workers are injured by the debris or parts such as grinding parts or grinding tool bits 450 are hit;

in addition, the debris collecting bucket 510 has a wide front end and a narrow rear end, so that the debris collecting and absorbing effects are better.

Although the numerical control grinding apparatus 10 having the debris collection function of the present invention collects the debris generated by grinding in a timely manner. But the more efficient collection device also cannot collect 100% of the debris completely and therefore inevitably has a small amount of debris entrained in the air. However, the specific control command for the numerical control grinding device 10 is inputted through the touch display screen 30, and the grinding processing state of the part and the state information of the numerical control grinding device 10 itself are displayed in real time through the touch display screen 30. Therefore, whether the touch display screen 30 works normally or not directly affects whether the numerical control grinding device 10 can work normally or not.

During the polishing process, the touch display screen 30 is exposed to the air of a workshop, and dust and debris are inevitably mixed in the air of 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 numerical control polishing device 10 is used, so that the touch display screen 30 is ensured not to be exposed in the air of a workshop any more, and therefore the dustproof, scratch-resistant and waterproof effects are achieved on the touch display screen 30, and the touch display screen 30 is effectively protected.

As shown in fig. 1, 6 and 7, the numerical control grinding housing 20 of the present invention is further provided with a protective outer frame 60 and a protective panel 70, the touch display screen 30 is nested and installed on the upper portion of the protective outer frame 60, the protective panel 70 is matched with the protective outer frame 60, and when the numerical control grinding device 10 operates, the protective panel 70 is slid open; when the digital control grinding device 10 is idle, the protective panel 70 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 dustproof, scratch-resistant and waterproof effects are achieved, and the touch display screen 30 is effectively protected.

As shown in fig. 6 and 7, the protective frame 60 is divided into an upper portion and a lower portion, the touch display screen 30 is nested and installed on the upper portion of the protective frame 60, the protective panel 70 slides along the protective frame 60, and when the protective panel 70 slides to the upper portion of the protective frame 60, the protective panel 70 covers the touch display screen 30 to protect the touch display screen 30; when the protection panel 70 slides down to the lower portion of the protection frame 60, the touch display screen 30 is exposed.

As shown in fig. 6 and 7, in order to protect the touch display 30, when the digital controlled polishing apparatus 10 is in an idle state, the protection panel 70 needs to cover the touch display 30 to protect the touch display 30. However, in practical applications, it is difficult to avoid the situation that the non-working person opens the protection panel 70 and exposes the touch display screen 30 in the air of the workshop; or the worker may open the protection panel 70, which should be in the closed state, due to an incorrect operation, so that the touch display screen 30 is exposed to the air in the workshop. In order to prevent a non-worker who is not familiar with the present numerical control sanding apparatus 10 from easily opening the protective panel 70 or a worker from mistakenly opening the protective panel 70, the present invention provides the following designs for the structures of the protective panel 70 and the protective casing 60, and the cooperation of the protective panel 70 and the protective casing 60:

as shown in fig. 8, in detail, a rocker guide groove 610 is provided at a lower portion of the protection frame 60, and a rocker rotation column 710 is provided at a rear surface of the protection panel 70. The rocker-type rotation post 710 is rotatably inserted into the rocker-type guide groove 610 and slidably disposed along the rocker-type guide groove 610.

As shown in fig. 8, a first guide groove 620 is formed at one side of the protection frame 60, and a matching protrusion 720 is formed at one side of the back surface of the protection panel 70, wherein the matching protrusion 720 is slidably disposed along the first guide groove 620. And, the matching protrusion strip 720 is connected with the first guiding groove 620 through the cover return spring 100, and the cover return spring 100 provides elastic restoring force for the matching protrusion strip 720 so that the protection panel 70 has a tendency of covering the touch display screen 30.

As shown in fig. 8, the other side of the protection frame 60 is provided with a second guide groove 630, a sliding connection block 200 is slidably disposed in the second guide groove 630, and the sliding connection block 200 is connected to the back surface of the protection panel 70 through a rocker return spring 300.

As shown in fig. 8 and 9, the protection panel 70 is provided with a fitting latch 730, the lower portion of the protection outer frame 60 is provided with a cover holding protrusion 640 and a reset-preventing stopper 650, and the cover holding protrusion 640 and the reset-preventing stopper 650 are spaced apart from each other. The fitting latch 730 is engaged with or separated from the cover holding protrusion 640, and the fitting latch 730 is engaged with or separated from the anti-reset stopper 650. In a preferred embodiment, an arc-shaped guide surface 641 (shown in fig. 9) is disposed on a side of the cover holding protrusion 640 away from the touch display screen 30.

As shown in fig. 8 and 9, the rocker return spring 300 and the cover-holding protrusion 640 are respectively disposed at both sides of the rocker guide slot 610; the cover holding protrusion 640 and the anti-reset stopper 650 are disposed on the same side of the rocker guide slot 610.

As shown in fig. 8, in the present embodiment, the number of the anti-reset blocking blocks 650 is multiple, and the multiple anti-reset blocking blocks 650 are arranged at intervals to form a multi-stage anti-reset block for the mating latch 730.

As shown in fig. 8, in this embodiment, the back surface of the protection panel 70 is further provided with an in-position reminding block 740, and the in-position reminding block 740 is in contact with or separated from the bottom edge of the protection outer frame 60.

As shown in fig. 9, 10 and 11, in the present embodiment, the radial cross section of the rocker guide groove 610 is arc-shaped; the radial cross section of the portion of the rocker-type rotation post 710 received in the rocker-type guide slot 610 is an arc-shaped structure. Such cooperation enables, on one hand, the seesaw-rotating column 710 to reciprocally slide along the axial direction of the seesaw-guiding groove 610, and, on the other hand, the seesaw-rotating column 710 to reciprocally rotate along the radial direction of the seesaw-guiding groove 610; when the rocker rotary column 710 reciprocally rotates along the radial direction of the rocker guide slot 610, the protection panel 70 performs a rocker motion with the rocker rotary column 710 as a fulcrum; this enables the protective panel 70 to cover and uncover the touch display screen 30.

The operation principle of the opening and closing of the protection panel 70 will be described below (please refer to fig. 1, 6 to 11):

when the protection panel 70 is covered on the touch display screen 30 (at this time, as an initial covering state), under the elastic force of the rocker return spring 300, the side of the protection panel 70 connected to the rocker return spring 300 is tilted upward, and the side away from the rocker return spring 300 is lowered, so that the protection panel 70 is in an inclined state; at this time, the matching fixture block 730 is clamped with the covering and maintaining bump 640 at the side of the protection panel 70 pressed downwards, and the covering and returning spring 100 is in an extending state; in this initial state, since the fitting latch 730 is engaged with the covering and retaining projection 640, the protection panel 70 cannot be directly slid downward;

if the protection panel 70 is opened to expose the touch display 30, the upturned side of the protection panel 70 needs to be pressed first; when the side of the protection panel 70 that is tilted up is pressed, the rocker-type rotation column 710 rotates along the rocker-type guide slot 610, that is, the protection panel 70 rotates with the rocker-type guide slot 610 as a fulcrum; during this process, rocker return spring 300 is constantly compressing and accumulating elastic potential energy;

when the protection panel 70 rotates to the horizontal state, the matching fixture block 730 and the covering and keeping lug 640 are in a separated state; at this time, the protection panel 70 slides downwards, so that the touch display screen 30 is gradually exposed; in the process of sliding down the protection panel 70, the rocker-type rotation post 710 slides down along the rocker-type guide slot 610; when the protection panel 70 slides down, the rocker return spring 300 and the sliding connection block 200 are driven to slide down together, and at this time, the sliding connection block 200 slides along the second guide groove 630; meanwhile, the engagement rib 720 slides down along the protection panel 70 and continuously compresses the closing return spring 100 so that the closing return spring 100 continuously accumulates elastic potential energy;

when the protection panel 70 slides down to the proper position, the side of the protection panel 70 provided with the matching fixture block 730 is pressed down, and then the hand can be released; when the side of the protection panel 70 where the fitting latch 730 is provided is pressed down, the rocker-type rotation column 710 rotates along the rocker-type guide groove 610 again, that is, the protection panel 70 generates a rocker motion again with the rocker-type guide groove 610 as a fulcrum; at the same time, rocker return spring 300 continues to extend and release elastic potential energy; when the side of the protection panel 70 provided with the matching fixture block 730 sinks, the matching fixture block 730 is firmly clamped with one of the anti-reset blocking blocks 650; at this time, the hand is released, and the protection panel 70 is stably maintained in the current tilted state (in this case, the opened state); in short, when the protection panel 70 is opened, a worker needs to press the protection panel 70 first, then slide the protection panel 70 downwards, and after the protection panel 70 slides downwards to the proper position, press the protection panel 70 again, so that the protection panel 70 is firmly clamped with one of the anti-reset blocking blocks 650; through a multi-step accurate operation mode, the phenomenon that the touch display screen 30 is exposed when the protective panel 70 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;

when the protection panel 70 needs to be covered again, the upwarped side of the protection panel 70 is pressed again; when the side of the protection panel 70 that is tilted up is pressed, the rocker-type rotation column 710 rotates along the rocker-type guide slot 610, that is, the protection panel 70 rotates with the rocker-type guide slot 610 as a fulcrum; during this process, rocker return spring 300 is constantly compressing and accumulating elastic potential energy; when the protection panel 70 rotates to a horizontal state, the fitting latch 730 is separated from the reset prevention stopper 650; at this time, the protection panel 70 is slid upward for a certain distance, that is, after the matching fixture block 730 leaves the position right above the plurality of anti-reset blocking blocks 650, the hand can be released; after the hand is released, the protection panel 70 is rapidly reset to the direction close to the touch display screen 30 under the action of the elastic restoring force of the cover reset spring 100 until the touch display screen 30 is completely covered by the protection panel 70; when the touch display screen 30 is completely covered by the protection panel 70, the protection panel 70 is restored to the initial state; at this time, under the elastic force of the rocker return spring 300, the side of the protection panel 70 connected to the rocker return spring 300 is kept tilted upward, and the side away from the rocker return spring 300 is kept sunk, so that the protection panel 70 is kept in a tilted state;

in the process of sliding the protection panel 70 along the protection outer frame 60 to be restored, the protection panel 70 also generates the seesaw movement again under the elastic restoring force of the seesaw restoring spring 300; namely, the protection panel 70 slides up and rotates; when the protection panel 70 slides up to the matching fixture block 730 to contact with the covering and retaining bump 640, at the moment that the matching fixture block 730 contacts with the covering and retaining bump 640, the matching fixture block 730 contacts with the arc-shaped guide surface 641 of the covering and retaining bump 640 and smoothly passes over the covering and retaining bump 640 under the guidance of the arc-shaped guide surface 641; the arc-shaped guide surface 641 ensures that the mating latch 730 smoothly passes over the covering and retaining bump 640 during the sliding reset process, so as to ensure that the protection panel 70 is smoothly reset and finally covers the touch display screen 30; in short, when the touch display screen 30 is covered, the user needs to press, push up and release the hand, and through a multi-step accurate operation mode, misoperation is effectively avoided to cover the touch display screen 30, and meanwhile, non-working personnel are prevented from easily covering the touch display screen 30 in work;

it should be noted that, at the moment that the fitting latch 730 passes over the covering and retaining bump 640, the protection panel 70 generates the seesaw movement under the upward lifting force of the covering and retaining bump 640 again with the seesaw guide slot 610 as the fulcrum; when the engaging latch 730 passes over the covering maintaining protrusion 640, the protection panel 70 is restored to the tilted state by the seesaw movement again under the elastic restoring force of the seesaw return spring 300; in short, when the fitting latch 730 passes over the covering and retaining bump 640 and at two moments after passing over the covering and retaining bump 640, the protection panel 70 undergoes two times of tilting movements in opposite directions, so as to ensure that the protection panel 70 is smoothly reset and is finally stably retained in a state of covering the touch display screen 30;

therefore, the rocker-type rotation column 710, the rocker-type guide groove 610, the sliding connection block 200, the rocker return spring 300 and the fitting latch 730, the covering and retaining protrusion 640, the arc-shaped guide surface 641 of the covering and retaining protrusion 640, the anti-return blocking block 650, etc. are tightly fitted with each other and are not independent; in the invention, the opening and closing of the protective panel 70 can be accurately, smoothly and quickly realized only by applying certain attention to the working personnel familiar with the numerical control polishing equipment 10; due to the design, the touch display screen 30 is effectively prevented from being opened or closed randomly by non-workers, 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;

further, when the protective panel 70 is slid down to the proper position, the proper position reminder block 740 collides with the bottom edge of the protective outer frame 60 to thereby generate an impact sound and simultaneously generate a downward sliding resistance, thereby reminding the worker that the protective panel 70 is slid down to the proper position;

according to the invention, the plurality of anti-reset blocking blocks 650 are arranged, so that multi-stage anti-reset limitation is formed, and clamping connection can be realized without strict and accurate alignment of the matched clamping block 730 and the anti-reset blocking blocks 650 when the protection panel 70 slides downwards; that is, the sliding position of the protection panel 70 is not required to be very accurate, and the protection panel 70 only needs to slide to the position above the region formed by the plurality of anti-reset blocking blocks 650 by the matching fixture block 730, so that the operation is more convenient and efficient;

moreover, the covering and keeping lug 640 and the anti-reset blocking block 650 are arranged at intervals; with such a design, after the one side of the protection panel 70 that is tilted up is pressed, the protection panel 70 is slid down to a position between the covering maintaining bump 640 and the anti-reset blocking block 650, and then the protection panel 70 is released, and at this time, the protection panel 70 automatically resets to the covering state under the action of the elastic restoring force of the covering reset spring 100, so as to ensure that the touch display screen 30 is covered again by the protection panel 70; such a design effectively prevents a non-worker unfamiliar with the numerical control grinding apparatus 10 from easily opening the protective panel 70 to partially expose the touch display screen 30; meanwhile, the misoperation condition that the touch display screen 30 is partially exposed due to the fact that the protective panel 70 slides down for a certain distance after the upper side and the tilted side are pressed by mistake is also effectively avoided.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
