[0002] In the field of product design, structural display models play a vital role in the evaluation and optimization of design solutions, and the appearance finishing of the model is the key link to ensure that it can accurately present the design intent.

[0003] With the continuous advancement of science and technology and the development of the product design industry, the requirements for model appearance finishing are becoming higher and higher. Traditional finishing methods often rely on manual tools, such as hammers, sandpaper, etc., which are not only inefficient, but also difficult to guarantee the finishing effect. It is difficult to control the strength and frequency of manual knocking and hammering, which can easily lead to damage to the model or uneven finishing; manual polishing is time-consuming and labor-intensive, and it is difficult to achieve high-precision surface quality requirements; and manual spray painting is prone to problems such as uneven paint layer and inconsistent thickness.

[0004] In addition, using multiple single-function tools for trimming is not only cumbersome to operate, but also takes up a lot of working space and time. In the pursuit of efficient, precise and high-quality product design, traditional trimming methods can no longer meet the needs of modern design.

[0005] In order to solve these problems, there is an urgent need for a product design structure display model appearance finishing device that integrates multiple functions such as knocking, hammering, grinding and painting to improve the finishing efficiency and quality and meet the ever-changing needs of the product design industry.

[0011] Preferably, a bearing frame is installed on the outer diameter of one side of the transmission shaft, a bending rod is fixedly connected to the top of the bearing frame, a blocking plate is fixedly connected to the end of the bending rod, a magnetic coupler is fixedly installed on the middle outer diameter of the rotating shaft, a slide groove is opened on one side of the bottom of the shell, and the bottom end of the bearing frame passes through the interior of the slide groove through a lever and is fixedly connected to a toggle block.

[0012] Preferably, an outer cover is fixedly connected to one side of the top of the shell, a liquid storage tank is fixedly connected to one side of the top of the shell close to the outer cover, a first fixed plate is fixedly connected to the inner middle of the outer cover, a plurality of liquid inlets are evenly arranged inside the first fixed plate, a liquid outlet is arranged at the inner side of the middle of the first fixed plate close to each liquid inlet, a first rubber valve is installed inside the liquid inlet, a second rubber valve is installed at one side of the first fixed plate close to the liquid outlet, and a rubber piston is fixedly installed at the other side of the first fixed plate close to each liquid inlet.

[0013] Preferably, a second fixing plate is fixedly connected to the inner part of the outer cover at a position close to one side of the first fixing plate, a first liquid outlet pipe is fixedly connected to the middle part of the second fixing plate, a second liquid outlet pipe is fixedly connected to one side of the first liquid outlet pipe, a discharge channel is opened on the inner upper side of the shell, a terminal end of the second liquid outlet pipe passes through the outside of the outer cover and extends to the inside of the discharge channel, and a terminal end of the discharge channel extends to one end of the shell and is fixedly installed with an atomizing nozzle.

[0014] Preferably, a liquid inlet branch pipe is fixedly connected to one side of the first fixed plate near each liquid inlet, and the ends of the liquid inlet branch pipes are fixedly connected to one end of the multi-way pipe, and the other end of the multi-way pipe extends to the interior of the liquid storage tank through the liquid inlet pipe.

[0016] Working principle: When it is necessary to knock and hammer the shape of the gypsum product model, start the second motor, drive the lower half of the shaft to rotate through the second motor, and use the magnetic coupler to drive the upper half of the shaft to rotate together. When the upper half of the shaft rotates, it will drive the half gear to rotate, and the rotating half gear will mesh with the rack plates at the front and rear ends of the inner wall of the straight groove frame in turn, thereby driving the straight groove frame to reciprocate left and right. The moving straight groove frame will drive the striker to follow the left and right reciprocating motion. When the striker moves to the left, it will push the rotating rod to move to the left and stretch the reset spring. When the striker moves to the right, the reset spring will reset the rotating rod. The cycle is repeated to realize the left and right reciprocating motion of the rotating rod, and then the hammer pad at the end of the rotating rod is used to knock, hammer and trim the gypsum model.

[0017] When the plaster model needs to be polished in appearance, the toggle block is pulled to the right, and the toggle block will drive the transmission shaft to move accordingly, so that the engaging head at the end of the transmission shaft is stuck in the engaging groove wheel on the short shaft, and at the same time, the bending rod will be driven to move, and the blocking plate will be extended into the middle of the magnetic coupler. Then the second motor is started again, and the second motor drives the lower half of the rotating shaft to rotate. Since the blocking plate extends into the middle of the magnetic coupler, the upper and lower parts of the rotating shaft are disconnected from the transmission connection, so the upper half of the rotating shaft cannot rotate, and the knocking and hammering function of the device is lost. The rotating sleeve drives the rotating rod to rotate through the cooperation of the spline and the keyway, thereby driving the grinding rod at the head of the rotating rod to rotate, and the high-speed rotating grinding rod is used to grind and trim the appearance of the plaster model.

[0018] When the plaster model needs to be painted, the paint liquid is poured into the liquid storage tank. At this time, the first motor is started to drive the connecting shaft to rotate. When the connecting shaft rotates, the eccentric wheel is driven to rotate. The eccentric rod is used to drive the three-head clamp to deflect, thereby driving the three rubber pistons to rise and fall alternately. When the rubber piston is compressed, the volume in the cavity decreases, and the air pressure increases. The first rubber valve is pressed to close the liquid inlet, and the second rubber valve is pushed open, and the liquid outlet is opened. The paint liquid in the cavity is discharged from the cavity and enters the first liquid outlet pipe, and then enters the outlet through the second liquid outlet pipe. The liquid in the liquid channel is sprayed on the surface of the plaster model through the action of the atomizing nozzle. When the rubber piston recovers, the volume in the cavity increases and the air pressure decreases. The external air pressure will press the second rubber valve to close the liquid outlet and push open the first rubber valve, and the liquid inlet will open. The paint liquid in the liquid storage tank will enter the cavity of the rubber piston again through the liquid inlet pipe, the multi-way pipe and the liquid inlet branch pipe under the action of atmospheric pressure. The cycle is repeated, and the three rubber pistons are used to complete the functions of liquid absorption and liquid discharge in turn. The paint liquid in the liquid storage tank is continuously extracted and sprayed out through the atomizing nozzle, so as to realize the paint finishing on the appearance of the plaster model.

[0019] The present invention provides a device for trimming the appearance of a product design structure display model. It has the following beneficial effects:

[0020] The present invention integrates the three functions of hammering, polishing and painting, can meet the various needs of the gypsum product model in the process of appearance finishing, avoids the inconvenience caused by using multiple single-function equipment, improves work efficiency, and the three functions can be flexibly switched according to actual needs. The operation is simple and convenient, which greatly saves time and labor costs. The overall structure is compact, occupies a small space, and is easy to carry and store.

[0030] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a device for trimming the appearance of a product design structure display model, such as Figure 1As shown, it includes a shell 1, which protects the internal structure and provides support. A handle 2 is fixedly connected to one side of the bottom of the shell 1 to facilitate the operation of the handheld device. A sleeve 24 is movably installed on one side of the inner side of the shell 1 through a bearing seat. The end of the sleeve 24 is connected to the inner wall of the shell 1 through the bearing seat. A rotating rod 25 is movably connected inside the sleeve 24. A second motor 29 is fixedly installed inside the handle 2. The driving end of the second motor 29 extends to the inside of the shell 1 and is fixedly connected to a rotating shaft 30. The rotating shaft 30 is divided into upper and lower parts by a magnetic coupler. The inside of the shell 1 A straight groove frame 31 is movably installed on the other side, and the side of the straight groove frame 31 is connected to the inner wall of the shell 1 through a guide rail. One end of the straight groove frame 31 close to the rear sleeve 24 is fixedly connected to a striker 34 and the end of the striker 34 extends to the inside of the striker 34, which is the main structure for pushing the rotating rod 25 to move, and has no direct contact with the rotating rod 25. The end of the rotating rod 25 is fixedly connected to a grinding rod 49, which is used to complete the main structure of grinding. The outer end of the grinding rod 49 is fixedly connected to a hammer pad 50, which is used to complete the main structure of knocking and hammering. A controller 51 is fixedly installed at the front end of the handle 2.

[0033] In this embodiment, key grooves 26 are provided on both sides of the interior of the sleeve 24, and splines 27 are fixedly connected to both ends of the rotating rod 25. The outer walls of the splines 27 are movably connected to the interior of the corresponding side key grooves 26. The splines 27 and key grooves 26 are arranged so that when the sleeve 24 rotates, the rotating rod 25 will rotate along with it, and when the sleeve 24 does not rotate, it will not affect the left and right movement of the rotating rod 25. The inner end of the rotating rod 25 is connected to the inner wall of the sleeve 24 through a reset spring 28. When the rotating rod 25 is pushed outward, it will stretch and accumulate elastic potential energy, which is convenient for pulling the rotating rod 25 back to its original position.

[0034] Furthermore, rack plates 32 are fixedly connected to the front and rear sides of the inner wall of the straight groove frame 31, and a half gear 33 is fixedly installed on the upper outer diameter of the rotating shaft 30, and the half gear 33 is always meshed with the inner end of one of the rack plates 32. When the half gear 33 rotates, it will mesh with the two rack plates 32 in turn, thereby driving the straight groove frame 31 to reciprocate left and right.

[0035] Specifically, when it is necessary to knock and hammer the shape of the gypsum product model, start the second motor 29, and drive the lower half of the rotating shaft 30 to rotate by the second motor 29, and use the action of the magnetic coupler 46 to drive the upper half of the rotating shaft 30 to rotate together. When the upper half of the rotating shaft 30 rotates, it will drive the half gear 33 to rotate, and the rotating half gear 33 will mesh with the rack plate 32 at the front and rear ends of the inner wall of the straight groove frame 31 in turn, thereby driving the straight groove frame 31 to reciprocate left and right. The moving straight groove frame 31 will drive the striker 34 to follow the left and right reciprocating motion. When the striker 34 moves to the left, it will push the rotating rod 25 to move left and stretch the reset spring 28. When the striker 34 moves to the right, the reset spring 28 will reset the rotating rod 25. The cycle is repeated to realize the left and right reciprocating motion of the rotating rod 25, and then the hammer pad 50 at the end of the rotating rod 25 is used to knock, hammer and trim the gypsum model.

[0036] Furthermore, a transmission shaft 35 is movably mounted on the lower part of the housing 1 near the sleeve 24 through a bearing seat. The transmission shaft 35 can move left and right. A long gear 36 is fixedly mounted on the outer diameter of the transmission shaft 35. The long gear 36 is always meshed with the spur gear 37. A spur gear 37 is fixedly mounted on the middle outer diameter of the sleeve 24. The long gear 36 and the inner side ends of the spur gear 37 are meshed and connected. When the long gear 36 rotates, it drives the spur gear 37 to rotate. The inner side end of the transmission shaft 35 is fixedly connected with a bite head 38, which cooperates with the bite groove wheel 40 to complete the motion transmission. A short shaft 39 is movably installed on one side of the inner part of the shell 1 near the rotating shaft 30 through a bearing seat, and an engaging groove wheel 40 is fixedly installed on the end of the short shaft 39 near the transmission shaft 35, which cooperates with the engaging head 38 to complete the motion transmission. A driven bevel gear 42 is fixedly installed on the end of the short shaft 39 near the rotating shaft 30, and a driving bevel gear 41 is fixedly installed on the lower outer diameter of the rotating shaft 30, and the inner ends of the driving bevel gear 41 and the driven bevel gear 42 are meshed and connected. When the driving bevel gear 41 rotates, it will drive the driven bevel gear 42 to rotate, and then drive the short shaft 39 and the engaging groove wheel 40 to rotate.

[0037] Furthermore, a bearing frame 43 is installed on the outer diameter of one side of the transmission shaft 35. The bearing frame 43 does not affect the rotation of the transmission shaft 35. A bending rod 44 is fixedly connected to the top of the bearing frame 43, and a blocking plate 45 is fixedly connected to the end of the bending rod 44. A magnetic coupler 46 is fixedly installed on the middle outer diameter of the rotating shaft 30. The blocking plate 45 extends into the middle of the magnetic coupler 46, which will disconnect the upper and lower parts of the rotating shaft 30 from the transmission connection. A slide groove 47 is opened on one side of the bottom of the shell 1, and the bottom end of the bearing frame 43 passes through the interior of the slide groove 47 through a lever and is fixedly connected to a toggle block 48, which is convenient for manual toggle to control the usage mode of the device.

[0038] Specifically, when the plaster model needs to be polished in shape, the toggle block 48 is pulled to the right, and the toggle block 48 will drive the transmission shaft 35 to move accordingly, so that the engaging head 38 at the end of the transmission shaft 35 is stuck in the engaging groove wheel 40 on the short shaft 39, and at the same time, the bending rod 44 is driven to move, and the blocking plate 45 is extended into the middle of the magnetic coupler 46, and then the second motor 29 is started again, and the second motor 29 drives the lower half of the rotating shaft 30 to rotate. Since the blocking plate 45 is extended into the middle of the magnetic coupler 46, the upper and lower parts of the rotating shaft 30 are disconnected from the transmission connection, so the upper half of the rotating shaft 30 cannot rotate, and the knocking and hammering function of the device fails. At this time, the rotating lower part of the shaft 30 will drive the active bevel gear 41 to rotate. The active bevel gear 41 drives the short shaft 39 and the meshing groove wheel 40 to rotate through the meshing transmission with the driven bevel gear 42. Since the meshing head 38 is stuck in the meshing groove wheel 40, the meshing head 38 and the transmission shaft 35 will rotate accordingly, so that the long gear 36 rotates accordingly and meshes with the spur gear 37, driving the sleeve 24 to rotate. The rotating sleeve 24 drives the rotating rod 25 to rotate through the cooperation of the spline 27 and the keyway 26, thereby driving the grinding rod 49 at the head of the rotating rod 25 to rotate, and the high-speed rotating grinding rod 49 is used to grind and trim the plaster model in appearance.

[0039] Furthermore, an outer cover 3 is fixedly connected to one side of the top of the shell 1, and a liquid storage tank 23 is fixedly connected to one side of the top of the shell 1 near the outer cover 3, with paint liquid inside and an opening at the top. A first fixing plate 4 is fixedly connected to the inner middle part of the outer cover 3 for connection and fixing. A plurality of liquid inlets 5 are evenly arranged inside the first fixing plate 4 for the paint liquid to enter the rubber piston 9 cavity. A liquid outlet 6 is arranged at the inner side of each liquid inlet 5 in the middle of the first fixing plate 4 for convenient discharge of the paint liquid in the rubber piston 9 cavity. A first rubber valve 7 is installed inside the liquid inlet 5, and a second rubber valve 8 is installed at a position near the liquid outlet 6 on one side of the first fixing plate 4. Both rubber valves are one-way valves. A rubber piston 9 is fixedly installed at a position near each liquid inlet 5 on the other side of the first fixing plate 4. Contraction and expansion will cause changes in the air pressure in the cavity, thereby controlling the inflow and outflow of the paint liquid.

[0040] Furthermore, a second fixed plate 10 is fixedly connected to the inner part of the outer cover 3 at a position near one side of the first fixed plate 4, and the connection is fixed. A first liquid outlet pipe 11 is fixedly connected to the middle part of the second fixed plate 10, and a second liquid outlet pipe 12 is fixedly connected to one side of the first liquid outlet pipe 11. A discharge channel 21 is opened on the inner upper side of the shell 1. The end of the second liquid outlet pipe 12 passes through the outside of the outer cover 3 and extends to the inside of the discharge channel 21 to facilitate the discharge of the paint liquid. The end of the discharge channel 21 extends to one end of the shell 1 and is fixedly installed with an atomizing nozzle 22, which can spray and atomize the paint liquid at high speed to improve the painting effect.

[0041] Furthermore, a liquid inlet branch pipe 13 is fixedly connected to one side of the first fixed plate 4 near each liquid inlet 5, and the end of the liquid inlet branch pipe 13 is fixedly connected to one end of the multi-way pipe 14, and the other end of the multi-way pipe 14 extends to the interior of the liquid storage tank 23 through the liquid inlet pipe 15, so as to facilitate the extraction of the paint liquid from the liquid storage tank 23.

[0042] Furthermore, the outer diameter of one side of the rubber piston 9 is fixedly connected to the outside of the three-head clamp 16, the middle part of the three-head clamp 16 is recessed inward, and a first motor 20 is fixedly installed at one end of the outer cover 3, and the driving end of the first motor 20 extends to the inside of the outer cover 3 through the connecting shaft 17. The end of the connecting shaft 17 is fixedly connected to an eccentric wheel 18, and one side of the eccentric wheel 18 is fixedly connected to an eccentric rod 19, and the end of the eccentric rod 19 is fixedly connected to the middle part of the three-head clamp 16. The first motor 20 drives the connecting shaft 17 to rotate. When the connecting shaft 17 rotates, the eccentric wheel 18 is driven to rotate. The three-head clamp 16 is driven to deflect by the action of the eccentric rod 19, thereby driving the three rubber pistons 9 to alternately rise and fall.

[0043] Specifically, when it is necessary to spray paint the plaster model, the paint liquid is poured into the liquid storage tank 23, and the first motor 20 is started at this time. The connecting shaft 17 is driven to rotate by the first motor 20. When the connecting shaft 17 rotates, the eccentric wheel 18 is driven to rotate. The eccentric rod 19 is used to drive the three-head clamp 16 to deflect, thereby driving the three rubber pistons 9 to alternately rise and fall. When the rubber piston 9 is compressed, the volume in the cavity decreases, and the air pressure increases. The first rubber valve 7 is pressed to close the liquid inlet 5, the second rubber valve 8 is pushed open, and the liquid outlet 6 is opened, and the paint liquid in the cavity is discharged from the cavity and enters the first liquid outlet pipe 11, and then enters the second liquid outlet pipe 12. The paint liquid in the liquid storage tank 23 enters the cavity of the rubber piston 9 again through the liquid inlet pipe 15, the multi-way pipe 14 and the liquid inlet branch pipe 13 by the effect of atmospheric pressure, and the three rubber pistons 9 are used to complete the effects of liquid absorption and liquid discharge in turn, and the paint liquid in the liquid storage tank 23 is continuously extracted and sprayed out through the atomizing nozzle 22, so as to realize the paint finishing on the appearance of the plaster model.
