Description

Technical Field

[0001] This application belongs to the technical field of grinding equipment, specifically relating to a workpiece clamping device and grinding equipment. Background Technology

[0002] In existing technologies, the grinding of strip workpieces is often done manually. For example, welded parts (such as coiled metal strips and band saw blades) formed by flash welding will have a 3-5mm protrusion in the weld seam after welding, which needs to be ground flat. Currently, the grinding of the weld seam of the above-mentioned welded parts is done by manually grinding the upper surface and then turning the saw blade over to grind the lower surface. Because the grinding accuracy requirement is high, experienced professionals are needed to ensure the grinding accuracy. However, manual grinding is inefficient and the flatness of the grinding is inconsistent. Iron filings and dust are also generated during the grinding process, resulting in a harsh working environment. In other words, the above grinding method is not only labor-intensive, but also has the disadvantages of high operator professionalism requirements, low efficiency, and low grinding quality consistency.

Detailed Implementation

[0041] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0042] Embodiments of this application provide a workpiece clamping device, such as... Figures 1-4 As shown, the workpiece clamping device includes a mounting base module 1, several clamping and positioning modules 2, a lower support module 3, and an upper support module 4. The workpiece clamping device has a first working state and a second working state.

[0043] Several clamping and positioning modules 2 are all mounted on the mounting base module 1 and together form a workpiece placement area. The clamping and positioning modules 2 are in a clamping state.

[0044] The lower support module 3 is movably mounted on the mounting base module 1 and has a first support state and a first avoidance state. In the first avoidance state, a first grinding wheel receiving space 301 is formed on the lower support module 3.

[0045] The upper support module 4 is movably disposed on the mounting base module 1 and located above the lower support module 3. The upper support module 4 has a second support state and a second avoidance state. In the second avoidance state, a second grinding wheel receiving space 404 is formed on the upper support module 4.

[0046] In the first working state, the lower support module 3 is in the first support state and the upper support module 4 is in the second avoidance state; in the second working state, the lower support module 3 is in the first avoidance state and the upper support module 4 is in the second support state.

[0047] Specifically, in this embodiment, the workpiece clamping device is suitable for a grinding equipment, which also includes an upper grinding mechanism 10 and a lower grinding mechanism 11. The workpiece in this embodiment is a welded part 7, which includes a weld strip and two weld protrusions located on opposite sides of the weld strip. The two weld protrusions include a first weld protrusion and a second weld protrusion. The grinding equipment is used to grind the first weld protrusion and the second weld protrusion on the welded part 7. The mounting base module 1 includes a mounting base 103, a first mounting plate 104 and a second mounting plate 105. The first mounting plate 104 and the second mounting plate 105 are both vertically arranged on the mounting base 103 and distributed laterally at intervals. There are two clamping and positioning modules 2. The two clamping and positioning modules 2 include a first clamping and positioning module 2 located on the first mounting plate 104 and a second clamping and positioning module 2 located on the second mounting plate 105. In the clamping state of the clamping and positioning modules 2, the weld strip of the welded part 7 is clamped by the clamping and positioning modules 2.

[0048] Before the welded part 7 needs to be ground, the clamping and positioning module 2 is in the open state, the lower support module 3 is in the first support state (or in the first clearance state), and the upper support module 4 is in the second clearance state (or in the second support state) so that the operator can place the welded part 7 in the grinding placement area. At this time, the workpiece clamping device is in the second working state. After the welded part 7 is placed, the upper support module 4 supports the welding strip from the bottom. Then, the clamping and positioning module 2 is controlled to change from the open state to the clamping state so that the two clamping and positioning modules 2 clamp the welding strip on the welded part 7 from both sides. After the welding strip is clamped, the first welding protrusion and the second welding protrusion are both located between the first mounting plate 104 and the second mounting plate 105, and the first welding protrusion is located above the second welding protrusion. In this case, the upper grinding mechanism 10 is controlled to move to the second grinding wheel receiving space 404 and perform the upper grinding operation so as to grind the first welding protrusion.

[0049] After the first welding protrusion is ground, the upper grinding mechanism 10 withdraws from the second grinding wheel receiving space 404 and returns to its initial position. The lower support module 3 changes from the first support state to the first avoidance state (or from the first avoidance state to the first support state), and the upper support module 4 changes from the second avoidance state to the second support state (or from the second support state to the second avoidance state). At this time, the workpiece clamping device is in the first working state. Then, the lower grinding mechanism 11 is controlled to move to the first grinding wheel receiving space 301 and perform the lower grinding operation to grind the second welding protrusion. After the second welding protrusion is ground, the lower grinding mechanism 11 withdraws from the first grinding wheel receiving space 301 and returns to its initial position. The clamping and positioning module 2 changes from the clamping state to the open state so that the operator can take out the ground welded part 7.

[0050] The workpiece clamping device in this embodiment has a simple structure, strong versatility, and high operational stability. After the clamping and positioning module 2 clamps the welded part 7, the upper support module 4 and the lower support module 3 alternately move between the avoidance state and the support state to form a first grinding wheel accommodating space 301 or a second grinding wheel accommodating space 404. This allows the grinding mechanisms corresponding to the first grinding wheel accommodating space 301 and the second grinding wheel accommodating space 404 to enter and grind the two welding protrusions on the welded part 7. This eliminates the need for multiple installations of the welded part 7, prevents adverse effects on the grinding of the welded part 7 due to secondary positioning, reduces labor costs, improves the grinding efficiency of the welded part 7, and also helps to improve the consistency of the grinding quality of the welded part.

[0051] In one embodiment of this application, the clamping and positioning module 2 includes a support block assembly 201 and a pressing assembly 202;

[0052] The support block assembly 201 is disposed on the mounting base module 1 and forms a workpiece placement area;

[0053] The pressing component 202 is vertically mounted on the mounting base module 1 and forms a clamping engagement with the support block component 201.

[0054] Specifically, a workpiece placement area is formed on the top surface of the support block assembly 201, and the pressing assembly 202 includes an upward state and a downward state. In this embodiment, when the pressing assembly 202 is in the upward state, there is a sufficient gap between the support block assembly 201 and its corresponding pressing assembly 202 so that the operator can place the weldment 7 in the workpiece placement area; when the pressing assembly 202 is in the downward state, the pressing assembly 202 and its corresponding support block assembly 201 form a clamping engagement so as to clamp the weldment 7 in the workpiece placement area.

[0055] In one embodiment of this application, the support block assembly 201 includes first support blocks 2011 that are laterally spaced on the mounting base module 1, and the pressing assembly 202 includes a pressing member 2021 and a first telescopic member 2022, with the pressing member 2021 corresponding to the first support block 2011.

[0056] The first telescopic component 2022 is vertically telescopically mounted on the mounting base module 1;

[0057] The pressing member 2021 is connected to the telescopic end of the first telescopic member 2022 and forms a clamping fit with the first support block 2011.

[0058] Specifically, in this embodiment, the support block assembly 201 includes two first support blocks 2011, one of which is disposed on the vertical sidewall of the first mounting plate 104, and the other is disposed on the vertical sidewall of the second mounting plate 105. The top surfaces of the two first support blocks 2011 together form a workpiece placement area. There are two pressing components 202, which are respectively disposed on the first mounting plate 104 and the second mounting plate 105. A pressing block portion 2023 is formed on the pressing member 2021. Each of the two pressing blocks 2023 is located directly above the two first support blocks 2011. The first telescopic member 2022 can be a telescopic cylinder (such as a telescopic air cylinder or a hydraulic telescopic cylinder). When the first telescopic member 2022 is in the extended state, the pressing block portion 2023 and the first support block 2011 are open, and there is a gap between them so that the operator can place the welded part 7 in the workpiece placement area. When the first telescopic member 2022 is in the retracted state, the pressing member 2021 and the corresponding first support block assembly 201 form a clamping engagement so as to clamp the welded part 7 in the workpiece placement area.

[0059] In one embodiment of this application, a first support block 2011 is disposed on a first vertical sidewall 101 of the mounting base module 1, a first telescopic member 2022 is disposed on a second vertical sidewall 102 of the mounting base module 1, the second vertical sidewall 102 is distributed opposite to the first vertical sidewall 101, and the pressing component 202 further includes a connector 2024.

[0060] One end of the connector 2024 is connected to the telescopic end of the first telescopic member 2022, and the other end of the connector 2024 passes through the mounting base module 1 and is connected to the pressing member 2021.

[0061] Specifically, in this embodiment, both the first mounting plate 104 and the second mounting plate 105 have longitudinal through holes 106, that is, the through holes 106 connect the space where the first vertical sidewall 101 is located and the space where the second vertical sidewall 102 is located. The connecting plate passes through the through holes 106 and connects to the lower pressing block 2023. When the first telescopic member 2022 extends and retracts, it drives the connecting member 2024 and the lower pressing block 2023 to move up and down, thereby realizing the opening or pressing between the lower pressing block 2023 and the first support block 2011. The above structure is simple, and the layout of each component is reasonable and compact, which is conducive to realizing the miniaturization design of the workpiece clamping device.

[0062] In one embodiment of this application, the workpiece clamping device further includes a positioning module 6;

[0063] The positioning module 6 is mounted on the mounting base module 1 and forms a positioning engagement with the welded part 7. The positioning module 6 includes multiple positioning elements 601 that are distributed laterally at intervals. The positioning elements 601 are in line contact with the welded part 7.

[0064] Specifically, in this embodiment, there are two positioning elements 601, which are respectively disposed in the two through holes 106 of the first mounting plate 104 and the second mounting plate 105. Further, the positioning element 601 can be a bearing or a block structure. In this embodiment, the positioning element 601 is preferably a bearing. During the process of placing the welded part 7 in the workpiece placement area, the bearing positions the welded part 7 in the longitudinal direction, and the outer wall of the outer ring of the bearing can be in line contact with the side wall of the welding strip (on the horizontal plane, the outer wall of the outer ring of the bearing can be in point contact with the side wall of the welding strip). The above settings can ensure that the welded part 7 is in a horizontal state after being placed in the workpiece placement area, and also help to avoid the positioning element 601 being worn too quickly, which helps to extend the service life of the positioning element 601.

[0065] In one embodiment of this application, both the lower support module 3 and the upper support module 4 include a first support component 401 and a second support component 402 that are symmetrically distributed in the lateral direction. Both the first support component 401 and the second support component 402 include a second telescopic member 4021 and a second support block 4022.

[0066] The second telescopic component 4021 is mounted on the mounting base module 1 and has an extended state and a retracted state;

[0067] The second support block 4022 is disposed at the telescopic end of the second telescopic member 4021;

[0068] In the extended state, the first support component 401 and the second support component 402 together form a support state, and a welding protrusion clearance gap 403 is formed between the first support component 401 and the second support component 402; in the retracted state, the first support component 401 and the second support component 402 together form a clearance state.

[0069] Specifically, the first support component 401 of the lower support module 3 and the first support component 401 of the upper support module 4 are both movably disposed on the vertical sidewall of the first mounting plate 104, and the second support component 402 of the lower support module 3 and the second support component 402 of the upper support module 4 are both disposed on the vertical sidewall of the second mounting plate 105. The second telescopic member 4021 of the first support component 401 and the second telescopic member 4021 of the second support component 402 extend or retract simultaneously. During the movement of the second telescopic member 4021, the lateral position and the longitudinal position of the second support block 4022 both change. In the lower support module 3, after the second telescopic member 4021 of the first support component 401 and the second telescopic member 4021 of the second support component 402 are extended, the second support block 4022 of the first support component 401 and the second support block 4022 of the second support component 402 jointly support the bottom surface of the welding strip. At this time, the top surface of the second support block 4022 and the top surface of the first support block 2011 are on the same horizontal plane, and the second welding protrusion is located in the welding protrusion clearance gap 403 between the second support block 4022 of the first support component 401 and the second support block 4022 of the second support component 402. In the upper support module 4, after the second telescopic member 4021 of the first support component 401 and the second telescopic member 4021 of the second support component 402 are extended, the second support block 4022 of the first support component 401 and the second support block 4022 of the second support component 402 jointly support the top surface of the welding strip. At this time, the bottom surface of the second support block 4022 and the top surface of the first support block 2011 are on the same horizontal plane, and the first welding protrusion is located in the welding protrusion clearance gap 403 between the second support block 4022 of the first support component 401 and the second support block 4022 of the second support component 402.

[0070] In the upper support module 4, when the second telescopic member 4021 of the first support component 401 and the second telescopic member 4021 of the second support component 402 are in a retracted state (at this time, the upper support module 4 is in a second clearance state), a second grinding wheel receiving space 404 is formed between the second support block 4022 of the first support component 401 and the second support block 4022 of the second support component 402; similarly, in the lower support module 3, when the second telescopic member 4021 of the first support component 401 and the second telescopic member 4021 of the second support component 402 are in a retracted state (at this time, the lower support module 3 is in a first clearance state), a first grinding wheel receiving space 301 is formed between the second support block 4022 of the first support component 401 and the second support block 4022 of the second support component 402.

[0071] In one embodiment of this application, the second telescopic member 4021 is telescopically disposed on the vertical sidewall of the mounting base module 1, and the second telescopic member 4021 is obliquely distributed on the vertical sidewall of the mounting base module 1.

[0072] Specifically, in this embodiment, the second telescopic member 4021 can be a telescopic cylinder (such as a telescopic air cylinder or a hydraulic telescopic cylinder). In the upper support module 4, the bottom surface of the second support block 4022 is the support surface; in the lower support module 3, the top surface of the second support block 4022 is the support surface. The second telescopic member 4021 is distributed along the inclined side on the mounting component, which allows the lateral and longitudinal positions of the second support block 4022 to be changed simultaneously by its extension or contraction without adding any additional components. That is, the support module can be switched between the avoidance state and the support state simply by extending or contracting the second telescopic member 4021. This simplifies the structure of the workpiece clamping device, reduces the overall height of the workpiece clamping device, and further improves the compactness of the layout between the components in the workpiece clamping device.

[0073] In one embodiment of this application, the workpiece clamping device further includes a limiting module 5;

[0074] The limiting module 5 is installed on the vertical side wall of the mounting base module 1, and the second support block 4022 forms a limiting engagement with the limiting module 5.

[0075] Specifically, the limiting module 5 includes a first limiting member 501 and a second limiting member 502, both of which are block-shaped. The first limiting member 501 is disposed on the first mounting plate 104, and the second limiting member 502 is disposed on the second mounting plate 105. The second support block 4022 has a limiting step surface. In the upper support module 4, during the extension of the second telescopic member 4021, the limiting step surfaces of the two second support blocks 4022 can respectively abut against the top surface of the first limiting member 501 and the top surface of the second limiting member 502; in the lower support module 3, during the extension of the second telescopic member 4021, the limiting step surfaces of the two second support blocks 4022 can respectively abut against the bottom surface of the first limiting member 501 and the bottom surface of the second limiting member 502. The limiting module 5 can play a hard limiting role for the second support block 4022 (in this embodiment, the pre-set extension length of the second telescopic member 4021 can play a soft limiting role for the second support block 4022), further ensuring the movement accuracy of the second support block 4022.

[0076] In one embodiment of this application, the workpiece clamping device further includes an air nozzle mounting module 8 and an air nozzle module 9;

[0077] The air nozzle mounting module 8 is mounted on the mounting base module 1;

[0078] The air nozzle module 9 is tilted on the air nozzle mounting module 8 and faces the workpiece placement area.

[0079] Specifically, the air nozzle mounting module 8 includes a first air nozzle mounting component 801 and a second air nozzle mounting component 802 respectively disposed on the first mounting plate 104 and the second mounting plate 105. The air nozzle module 9 includes a first air nozzle 901, a second air nozzle 902, a third air nozzle 903 and a fourth air nozzle 904 all facing the workpiece placement area. The first air nozzle 901 and the second air nozzle 902 are disposed on the first air nozzle mounting component 801 and are vertically spaced apart, while the third air nozzle 903 and the fourth air nozzle 904 are disposed on the second air nozzle mounting component 802 and are vertically spaced apart. When the upper grinding mechanism 10 grinds the first welding protrusion, the first air nozzle 901 and the third air nozzle 903 perform the blowing function to blow away the metal debris generated during the grinding of the first welding protrusion and reduce the temperature of the welded part 7; when the lower grinding mechanism 11 grinds the second welding protrusion, the second air nozzle 902 and the fourth air nozzle 904 perform the blowing function to blow away the metal debris generated during the grinding of the second welding protrusion and reduce the temperature of the welded part 7.

[0080] The embodiments of this application provide a grinding device, which includes an upper grinding mechanism 10, a lower grinding mechanism 11, and the workpiece clamping device in the above embodiments;

[0081] The upper grinding mechanism 10 is movably mounted on the upper side of the workpiece clamping device;

[0082] The lower grinding mechanism 11 is movably disposed on the lower side of the workpiece clamping device.

[0083] Specifically, such as Figures 3-4 As shown, when the first welding protrusion needs to be ground, the upper grinding mechanism 10 moves to the second grinding wheel receiving space 404 and performs the upper grinding operation. After the first welding protrusion is ground, the upper grinding mechanism 10 withdraws from the second grinding wheel receiving space 404 and returns to its initial position. When the first welding protrusion is ground and the second welding protrusion needs to be ground, the lower grinding mechanism 11 moves to the first grinding wheel receiving space 301 and performs the lower grinding operation. After the second welding protrusion is ground, the lower grinding mechanism 11 withdraws from the first grinding wheel receiving space 301 and returns to its initial position.
