Description

TECHNICAL FIELD

[0001] The present application relates to the field of grinding processing, in particular to a grinding device for processing cuboid sheet. BACKGROUND

[0002] The slide sheet of an air conditioner compressor needs to grind mounting connecting parts at its end to realize subsequent assembly. The existing processing is generally manually clamped on a tool one by one, and then ground by a grinding head. However, since the air conditioner compressor slide sheet is a cuboid sheet with small volume, it is inconvenient for an operator to take, and only one workpiece can be processed in the process of one-time feeding, one-time grinding and one-time discharging, so the processing efficiency is very low. SUMMARY

[0003] In order to overcome the deficiencies in the prior art, the present application provides a grinding device for processing cuboid sheet, which has the advantage of improving production efficiency.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0005] A grinding device for processing cuboid sheet, the grinding device further comprises a grinding tool arranged on the sliding table; the grinding tool has a placement groove arranged in the length direction along the sliding direction of the sliding table, a pressing assembly and a gas pressure detection assembly; the placement groove is used for placing a batch of cuboid sheets, and the length direction of the cuboid sheet is the same as the length direction of the placement groove; the pressing assembly is used for applying pressure to the cuboid sheet in the placement groove, which is perpendicular to the length direction of the cuboid sheet; the grinding mechanism is used for grinding the batch of cuboid sheets on the grinding tool; and the gas pressure detection assembly is used for detecting whether the placement groove is out of stock.

[0006] By adopting the above technical scheme, a batch of cuboid sheets can be placed in the placement groove at one time, and then the pressing assembly applies pressure to the cuboid sheet in the placement groove, which is perpendicular to the length direction of the cuboid sheet, to fix the cuboid sheet. Then the grinding mechanism completes the grinding of the batch of cuboid sheets. In this way, the process of one-time feeding, one-time grinding and one-time discharging can complete the processing of the batch of cuboid sheets, improving the production efficiency. At the same time, the gas pressure detection assembly is used to detect whether the placement groove is out of stock, so as to replenish the material in time.

[0007] Optionally, the pressing assembly is provided with a first pressure and a second pressure, and the second pressure is greater than the first pressure; when the pressing assembly applies the first pressure, the batch of cuboid sheets are horizontally aligned; and when the pressing assembly applies the second pressure, the batch of cuboid sheets are ground.

[0008] By adopting the technical scheme, the first pressure of the pressing assembly can realize the pre-positioning of the batch of cuboid sheets, the position of the cuboid sheets can be adjusted in this state, the cuboid sheets are moved and aligned in the horizontal direction, and the processing positions are in the same horizontal plane by moving in the vertical direction, due to the accurate positioning of the cuboid sheets and the cooperation of the second pressure and the third pressure, the operator does not need to manually transfer the workpiece or reset the clamping force after alignment, the production cycle is greatly shortened, human intervention is reduced, and it is very suitable for batch automatic production.

[0009] Optionally, the alignment mechanism further comprises an alignment support arranged on the workbench, an alignment lifting assembly arranged on the alignment support, and an alignment abutting assembly; the alignment lifting assembly is used to drive the alignment abutting assembly to vertically lift; the alignment abutting assembly comprises an alignment roller; the alignment roller is in the same vertical plane as the cuboid sheet.

[0010] By adopting the technical scheme, the alignment roller will be in contact with the upper end faces of all the cuboid sheets in turn during the horizontal movement of the sliding table, the grinding tool and the batch of cuboid sheets, so that the batch of cuboid sheets are horizontally aligned, the subsequent grinding position is accurate, and the grinding quality is improved.

[0011] Optionally, the grinding mechanism comprises a pair of grinding assemblies distributed on both sides of the width direction of the arrangement groove; the grinding assembly comprises a grinding head component.

[0012] By adopting the technical scheme, since the rigidity of the cuboid sheet in the width direction is limited, if only one side is provided with the grinding head component, the deformation of the cuboid sheet will be caused when the grinding head component grinds, which affects the grinding quality; the symmetrical grinding head components are arranged on both sides of the cuboid sheet, and the grinding head components grind at the same time, so that the force balance of the cuboid sheet is achieved, the deformation of the cuboid sheet is avoided, and the grinding efficiency is improved.

[0013] Optionally, the grinding assembly further comprises a horizontal driving component; the horizontal driving component is used to drive the grinding head component to move along the width direction of the arrangement groove.

[0014] By adopting the technical scheme, the pair of grinding head components are driven by the pair of horizontal driving components to move away from or close to each other, so that the cuboid sheets with different thicknesses can be processed, and the feeding and discharging of the cuboid sheets are facilitated, and the feeding and discharging are more convenient.

[0015] Optionally, the device further comprises a warning light and a controller; the bottom of the accommodation groove is provided with a plurality of detection air holes which are uniformly distributed along the length direction of the accommodation groove; each detection air hole corresponds to one cuboid sheet; all the detection air holes are connected with an external air extraction device; the air pressure detection assembly comprises an air pressure sensor; the air pressure sensor is arranged between the air inlet of the air extraction device and the detection air hole; the air pressure sensor is electrically connected with the controller; the controller is used to control the warning light and the grinding mechanism.

[0016] By using the above technical scheme, when the number of the cuboid sheets in the accommodation groove is less than the set number, the detection air hole is in an unblocked state, at this time, when the external air extraction device works, the air pressure sensor at the air inlet of the air extraction device detects a pressure less than the set value, at this time, the air pressure sensor sends a signal to the controller, the controller controls the warning light to start and reminds the operator of the lack of parts, and controls the grinding mechanism to be unable to start, thereby preventing accidental start when the cuboid sheets are replenished.

[0017] Optionally, one end of the length direction of the accommodation groove is a closed end, and the other end is an open end; the grinding tool has a pushing assembly; the pushing assembly comprises a pushing plate matched with the accommodation groove and a pushing driving part; the pushing driving part is used to drive the pushing plate to reciprocate at the open end of the accommodation groove to push the cuboid sheets; the controller controls the pushing assembly to start after receiving the signal of the air pressure sensor.

[0018] By using the above technical scheme, when the number of the cuboid sheets in the accommodation groove is equal to the set number, the pushing assembly makes all the cuboid sheets abut against each other, in the grinding process, the abutting cuboid sheets form a rigid whole, thereby effectively preventing the cuboid sheets from producing slight displacement or vibration in the processing process, and improving the grinding quality; when the number of the cuboid sheets in the accommodation groove is less than the set number, the pushing driving part makes the existing cuboid sheets in the accommodation groove abut against each other, so that the part close to the open end of the accommodation groove forms a gap due to the small number of the cuboid sheets, at this time, the cuboid sheets can be replenished at this position, so that the number of the cuboid sheets is equal to the set number, thereby greatly improving the efficiency of the replenishment without checking the position of the lack of parts.

[0019] Optionally, one end of the pushing plate close to the closed end of the accommodation groove is provided with a pressure sensor; the pressure sensor is electrically connected with the controller; when the pressure between the pushing plate and the cuboid sheet is greater than the set value, the controller controls the pushing driving part to start to drive the pushing plate to return.

[0020] By adopting the technical scheme, all the cuboid sheets in the accommodation groove can be abutted against each other through one pushing, and the gaps caused by the lack of material are all concentrated in the part of the opening end of the accommodation groove, so that the pushing effect is better, and subsequent rapid replenishment is facilitated.

[0021] Optionally, the grinding tool has a replenishment mechanism; the replenishment mechanism is used for replenishing the cuboid sheets to the opening end of the accommodation groove.

[0022] By adopting the technical scheme, the existence of the replenishment mechanism can reduce manual replenishment, improve the convenience and safety of replenishment.

[0051] Referring to Figure 4 , in order to ensure the position accuracy of the cuboid sheet 100, the force applying member 45 is provided with a first pressure and a second pressure, and the second pressure is greater than the first pressure; when the force applying member 45 applies the first pressure, the batch of cuboid sheets 100 is horizontally aligned; and when the force applying member 45 applies the second pressure, the batch of cuboid sheets 100 is subjected to grinding processing.

[0052] Referring to Figures 2-4, the grinding mechanism 50 further comprises a pair of grinding assemblies 60 distributed on both sides of the width direction of the installation groove 420; the grinding assembly 60 comprises a grinding head component 66, a vertical driving component and a horizontal driving component; the horizontal driving component comprises a horizontal moving seat 61 horizontally arranged on the workbench 10 and a horizontal driving member 62 for driving the horizontal moving seat 61 to move along the width direction of the installation groove 420; the vertical driving component comprises a vertical moving seat 64 vertically arranged on the horizontal moving seat 61 and a vertical driving member 63 for driving the vertical moving seat 64 to move in the vertical direction; wherein the horizontal driving member 62 and the vertical driving member 63 can adopt a ball screw pair or a linear motor drive, and the structure of the ball screw pair and the linear motor adopts the existing structure, which will not be described here; the grinding head component 66 comprises a grinding servo motor 661 fixed on the vertical moving seat 64 and a grinding wheel 662 coaxially fixed on the output shaft of the grinding servo motor 661; the axis of the grinding servo motor 661 is vertically arranged and the grinding wheel 662 is located on the lower side of the grinding servo motor 661; the outer surface of the grinding wheel 662 is adapted to the shape of the mounting connecting part 102 of the air conditioner compressor vane 101, which will be described in detail below Figure 5 , that is, the two working surfaces 103 of the upper end of the air conditioner compressor vane 101 are adapted to the outer surface of the grinding wheel 662.

[0053] Embodiment two: Since the cuboid sheet 100 is batch clamped, the number of cuboid sheets 100 in the installation groove 420 may be less than the set number, that is, the workpiece is missing, which is referred to as material shortage in the following.

[0054] Reference Figure 7 , based on the above technical problems, the difference between embodiment two and embodiment one is that the grinding tool 40 further comprises a gas pressure detection assembly; the gas pressure detection assembly comprises a gas pressure sensor 46; the bottom of the installation groove 420 is provided with a plurality of detection gas holes 421 uniformly distributed along the length direction thereof; the detection gas hole 421 corresponds to the cuboid sheet 100 one by one; all the detection gas holes 421 are connected with an external air extraction device; the gas pressure sensor 46 is arranged at the air inlet of the air extraction device; the gas pressure sensor 46 is electrically connected with the controller; reference Figure 8 , in addition, the workbench 10 is provided with a warning lamp 90; the warning lamp 90 is electrically connected with the controller, and the controller is used for controlling the warning lamp 90. In other embodiments, the tool body 42 is formed with a total gas pipe 422 arranged along the length direction thereof; the total gas pipe 422 is in communication with all the detection gas holes 421, the outlet of the total gas pipe 422 is connected with the air inlet of the air extraction device through an external gas pipe 423, and the gas pressure sensor 46 is arranged on the external gas pipe 423.

[0055] When the number of cuboid sheets 100 in the installation groove 420 is less than the set number after the feeding is completed, the detection air hole 421 is in the unblocked state, at this time, when the external air extraction device works, the air pressure sensor 46 of the air inlet of the air extraction device detects a pressure less than the set value, at this time, the air pressure sensor 46 sends a signal to the controller, the controller controls the warning light 90 to start, reminding the operator that the workpiece is missing. In addition, in order to prevent the grinding mechanism 50 from starting suddenly when the workpiece is missing, the controller controls the grinding mechanism 50 so that it cannot start, preventing the operator from accidentally starting when replenishing the cuboid sheet 100.

[0056] Example three: the difference between example three and example two is that: reference Figure 7 In order to further improve the convenience of the operator to replenish the cuboid sheet 100, the grinding tool 40 is provided with a pushing assembly 48 near one end of the opening end of the installation groove 420. The pushing assembly 48 includes a pushing cylinder 481 fixed on the tool base 41, a connecting plate 482 fixed on the piston rod of the pushing cylinder 481, and a pushing plate 483 fixed on the connecting plate 482; the extension direction of the pushing cylinder 481 is parallel to the length direction of the installation groove 420; the length direction of the pushing plate 483 is the same as the length direction of the installation groove 420 and extends into the installation groove 420; the controller is used to control the pushing cylinder 481, and the stroke of the pushing cylinder 481 is the length of one cuboid sheet 100. In this way, when the workpiece is missing, the air pressure sensor 46 sends an electrical signal to the controller, and the controller controls the pushing cylinder 481 to start and drive the pushing plate 483 to move inwardly in the installation groove 420, thereby pushing the cuboid sheet 100 to move to eliminate the gap caused by the lack of cuboid sheet 100, so that the operator can replenish near the opening end of the installation groove 420, without having to find the position where the cuboid sheet 100 is missing, greatly improving the convenience of the operator to replenish.

[0057] In other embodiments, the pushing plate 483 can not be pushed by a cylinder with a fixed stroke, but by other pushing driving components, such as a gear and rack mechanism combined with a servo motor, and a pressure sensor is installed at the end of the pushing plate 483, which is electrically connected with the controller, when the pressure detected by the pressure sensor exceeds the set value, it indicates that all the cuboid sheets 100 are in contact with each other and there is no gap in between, so that when the number of missing materials exceeds one, the pushing efficiency is higher.

[0058] Example four: the difference between example four and example three is that: reference Figure 8 and Figure 10In order to further improve the safety of the operator when replenishing the cuboid sheet 100, the workbench 10 is provided with a replenishment mechanism 80 to realize automatic replenishment; the replenishment mechanism 80 is used to replenish the cuboid sheet 100 to the opening end of the accommodation groove 420; and the controller is used to control the replenishment mechanism 80.

[0059] With reference to Figure 10 The replenishment mechanism 80 comprises a gantry-shaped replenishment support 81 fixed on the workbench 10, a storage assembly 83 vertically penetrating the horizontal part of the replenishment support 81, and a replenishment lifting assembly used to drive the storage assembly 83 to vertically lift.

[0060] With reference to Figure 11 The storage assembly 83 comprises a vertically arranged rectangular frame column-shaped storage rack 831 and a limiting component; the space in the storage rack 831 is used for vertically stacking the cuboid sheets 100; and the limiting component is used to limit the cuboid sheet 100 at the lowermost end; and the specific structure is as follows: the limiting component comprises a limiting cylinder 833 fixed on the storage rack 831 and a limiting pressing column 834 fixed on the piston rod of the limiting cylinder 833; and the limiting pressing column 834 horizontally penetrates the side wall of the storage rack 831.

[0061] With reference to Figure 10 And Figure 11 The replenishment lifting assembly comprises a pair of replenishment lifting cylinders 82 fixed on the top surface of the replenishment support 81; the upper end of the storage rack 831 is fixed with a pair of extension connecting plates 832; the extension connecting plates 832 correspond to the replenishment lifting cylinders 82 one by one and are fixed on the upper end of the piston rod of the corresponding side replenishment lifting cylinder 82.

[0062] When replenishing, the pair of replenishment lifting cylinders 82 drives the storage assembly 83 to descend, so that the lower end of the storage rack 831 approaches the tool main body 42, then the limiting cylinder 833 is started, so that the limiting pressing column 834 is retracted, so that all the cuboid sheets 100 are moved downward together, the cuboid sheet 100 at the lowermost end falls into the accommodation groove 420, the second cuboid sheet 100 from bottom to top becomes the cuboid sheet 100 at the lowermost end in the storage rack 831, then the limiting cylinder 833 is started to make the limiting pressing column 834 extend to reset against the cuboid sheet 100 at the lowermost end in the storage rack 831, then the pair of replenishment lifting cylinders 82 drives the storage assembly 83 to ascend to reset, so that the replenishment of one cuboid sheet 100 is completed.

[0063] The working principle is as follows: firstly, the gas pressure sensor 46 detects whether the material is insufficient, if the material is insufficient, a signal is given to the controller, the controller controls the pushing assembly 48 to start, so that the installation groove 420 exposes the replenishment gap close to the open end, and the controller controls the replenishment mechanism 80 to replenish a cuboid sheet 100; then the gas pressure sensor 46 detects whether the material is insufficient again, if the material is insufficient, the above working principle is followed to replenish; when the material is sufficient, the controller controls the pressing assembly to apply pressure to the cuboid sheet 100.

[0064] In other embodiments, referring to Figure 8 , in order to facilitate the adjustment of the height of the cuboid sheet 100 when the force applying piece 45 applies a gear pressure, so that the upper end surfaces of all the cuboid sheets 100 are on the same horizontal plane, the workbench 10 is provided with an alignment mechanism 70; referring to Figure 9 , the alignment mechanism 70 includes a gantry-shaped alignment bracket 71 fixed on the workbench 10, an alignment lifting assembly 72 fixed on the alignment bracket 71, and an alignment abutting assembly; the alignment lifting assembly 72 adopts a gas cylinder, and the alignment abutting assembly includes an abutting seat 73 fixed on the lower end of the piston rod of the alignment lifting assembly 72 and an alignment roller 74 rotationally connected to the abutting seat 73; the alignment roller 74 is on the same vertical plane as the cuboid sheet 100.

[0065] In other embodiments, an automatic feeding mechanism can be provided, the structure of the automatic feeding mechanism can refer to the feeding mechanism 80, and the feeding function of the feeding mechanism 80 is used to realize feeding in cooperation with the horizontal movement function of the sliding table 30, the sliding table driving mechanism 20 and the grinding tool 40. However, the efficiency of this feeding mode is not very high; in other embodiments, the automatic feeding mechanism includes a feeding translation assembly, a feeding translation frame, a feeding lifting assembly, a feeding lifting frame and a feeding clamping tool. The feeding translation assembly drives the feeding translation frame to move along the parallel direction of the sliding table 30. The feeding lifting frame is vertically slidably arranged on the feeding translation frame. The feeding lifting assembly drives the feeding lifting frame to vertically lift. The feeding clamping tool is installed on the feeding lifting frame. The structure of the feeding clamping tool can refer to the grinding tool 40 in Embodiment 1. However, the feeding clamping tool is used to clamp the upper end of the batch of cuboid sheets 100. Both the feeding translation assembly and the feeding lifting assembly can be driven by a ball screw pair or a linear motor. The structure of the ball screw pair and the linear motor adopts the existing structure, which will not be described here. In order to facilitate the operator to feed the feeding clamping tool, a rotary driving assembly is arranged between the feeding lifting frame and the feeding clamping tool. The rotary driving assembly is used to drive the feeding clamping tool to rotate in the vertical plane. When manually feeding the feeding clamping tool, the opening of the accommodation groove 420 of the feeding clamping tool is inclined upward. When feeding the grinding tool 40 on the sliding table 30, the opening of the accommodation groove 420 of the feeding clamping tool is vertically downward. The connection structure of the feeding lifting frame and the feeding clamping tool is as follows: the feeding lifting frame and the feeding clamping tool are hinged, and the hinge shaft direction is horizontal and parallel to the sliding direction of the sliding table 30. The rotary driving assembly can be a pneumatic cylinder. The two ends of the pneumatic cylinder are hinged to the feeding lifting frame and the feeding clamping tool respectively.

[0066] In other embodiments, referring to Figure 12The side limiting module 49 is arranged on the side wall of the installation groove 420 away from the compression strip 44, and is uniformly distributed in a plurality of water levels. The side limiting module 49 corresponds to the cuboid sheet 100 one by one. The side limiting module 49 includes an extension top block 491, an electromagnet 492 and a pair of compression springs 493. The horizontal extension groove 424 is formed on the side wall of the installation groove 420 away from the compression strip 44. The extension top block 491 is arranged in the horizontal extension groove 424 and the extension direction is perpendicular to the compression strip 44. The horizontal extension groove 424 is formed with a plurality of spring installation grooves 425 and a plurality of electromagnet installation grooves 426 on the side wall away from the compression strip 44. The electromagnet 492 is installed in the electromagnet installation groove 426, and the extension top block 491 is embedded with an adsorption block matched with the electromagnet 492 on the end surface away from the compression strip 44. The spring installation groove 425 is screwed with a sealing seat 494 away from the opening of the horizontal extension groove 424. The compression spring 493 is located between the sealing seat 494 and the extension top block 491 and is used to provide the pressure of the extension top block 491 to the cuboid sheet 100. The end of the extension top block 491 close to the cuboid sheet 100 is isosceles trapezoidal, that is, the two vertical edge lines of the end surface of the extension top block 491 close to the cuboid sheet 100 are chamfered into inclined guide surfaces 4911. The extension top block 491 is opposite to the cuboid sheet 100, and the width of the sealing seat 494 is equal to the length of the cuboid sheet 100.

[0067] In order to ensure the accuracy of the extension direction of the sealing seat 494, translation guide strips 4912 are respectively formed on the upper and lower end surfaces of the sealing seat 494. The direction of the translation guide strip 4912 is perpendicular to the cuboid sheet 100. A plurality of translation guide grooves matched with the translation guide strip 4912 are respectively formed on the upper and lower side walls of the horizontal extension groove 424.

[0068] Before the cuboid sheet 100 is fed, the electromagnet 492 is energized to generate an adsorption force to adsorb the adsorption block of the extension top block 491, so that the extension top block 491 is retracted in the horizontal extension groove 424. When the cuboid sheet 100 is fed, the electromagnet 492 loses power and loses the adsorption force. Under the action of the pair of compression springs 493, the extension top block 491 is extended. If there is no shortage of materials, the extension top block 491 will abut against the corresponding cuboid sheet 100, further ensuring the position stability of the cuboid sheet 100. If there is a shortage of materials, the extension top block 491 will extend into the gap of the shortage. At this time, the extension top block 491 compensates for the gap, and the cuboid sheets 100 on both sides of the gap will be in contact with the vertical end surfaces of the extension top block 491. During subsequent grinding of the cuboid sheet 100, displacement along the length direction will not be caused due to the shortage of materials. At this time, it is actually unnecessary to pay attention to the shortage of materials, and the operator does not need to supplement the materials, thereby improving the production efficiency of the machining. The inclined guide surface 4911 on the extension top block 491 can facilitate the extension into the gap of the shortage.
