[0028] Due to reasons such as installation errors, the parallel relationship referred to in the embodiments of the present invention may actually be an approximate parallel relationship, and the vertical relationship may actually be an approximate vertical relationship.

[0029] The present utility model provides a load grinding test device, which is mainly used for performing grinding / polishing performance tests on existing handheld grinding / polishing devices, comparing and testing different models of devices under the premise of providing unified test conditions, etc. Preferably, in this embodiment, the grinding / polishing device is a handheld sander 34. Refer to Figure 1 , the load grinding test device includes an equipment cabinet 1, a pressing device 4, and a clamping assembly 3.

[0030] Refer to Figure 2 and Figure 3 , a horizontal workbench surface 11 is provided in the middle of the equipment cabinet 1. The workbench surface 11 is used to set test consumables 2 for grinding tests. The test consumables 2 are mainly plates, preferably wooden boards. The wooden boards are placed flat on the workbench surface 11. A pressing device 4 for fixing the test consumables 2 in the horizontal direction is provided on the side of the workbench surface 11.

[0031] A perforated plate is provided on the surface of the workbench surface 11. A dust collection hopper 12 and a vacuum cleaner assembly 13 are connected and provided below the perforated plate. The debris and dust generated during the grinding work of the test consumables 2 can fall downward through the perforated plate into the dust collection hopper 12. When the vacuum cleaner assembly 13 works, it can also generate suction on the surface of the dust collection hopper 12 to attract dust and debris.

[0032] Refer to Figure 3 and Figure 7 , the pressing device 4 includes a pressing plate 41 and a resisting plate 43 respectively arranged on opposite sides of the workbench surface 11. The resisting plate 43 is fixedly connected to the workbench surface 11. A pressing cylinder 42 is provided on the pressing plate 41. The pressing cylinder 42 is fixedly connected to the workbench surface 11. The pressing plate 41 is fixed to the telescopic end of the pressing cylinder 42. The telescopic movement of the pressing cylinder 42 drives the horizontal lateral movement of the pressing plate 41. When the test consumables 2 are placed on the workbench surface 11, one end of the test consumables 2 abuts against the resisting plate 43, and the other end is tightly pressed by the pressing plate 41, so as to realize the full fixation of the test consumables 2 on the workbench surface 11.

[0033] Refer to Figure 4 and Figure 5, the clamping assembly 3 is arranged above the workbench surface 11 and includes a connecting plate 31 and a positioning plate 33. The positioning plate 33 is used for fixedly installing the device to be tested, that is, the sander 34. The positioning plate 33 is installed at one end of the connecting plate 31. A translation module is arranged on one side of the workbench surface 11. The translation module includes a guide rail 321 and a bottom plate 322 slidably connected to the guide rail 321. The connecting plate 31 is fixedly connected to the bottom plate 322. The translational movement of the bottom plate 322 along the guide rail 321 drives the translation of the sander 34 clamping assembly 3, so that the sander 34 can travel and polish along the surface of the test consumable 2. Among them, the driving mode of the relative sliding translation between the bottom plate 322 and the guide rail 321 can adopt an electric form, that is, similar to the principle of a linear motor.

[0034] In this embodiment, the sander 34 includes a machine shell and a motor arranged in the machine shell. A grinding wheel is arranged at the bottom of the machine shell. The grinding wheel is driven by the motor to rotate and polish. After the sander 34 is installed on the positioning plate 33, the grinding wheel is arranged downward on the top surface of the test consumable 2. When the sander 34 is started, the surface of the test consumable 2 is polished. During the translation of the clamping assembly 3 along the guide rail 321, the sander 34 is translated and polished along the surface of the test consumable 2.

[0035] Refer to Figure 6 , the positioning plate 33 has a U-shaped structure and includes an opening for the horizontal installation of the sander 34 into the positioning plate 33. During installation, the inner peripheral wall of the U-shape of the positioning plate 33 is used to be clamped with the outer peripheral wall of the machine shell of the sander 34, and the grinding wheel of the sander 34 is placed horizontally downward on the surface of the test consumable 2.

[0036] In order to limit the position of the sander 34 in the positioning plate 33, a stop bar 331 is further arranged on the positioning plate 33. The stop bar 331 is horizontally arranged at the opening of the U-shaped structure of the positioning plate 33, so as to form a closure for the sander 34, ensure the stable position of the sander 34 during the translational polishing work, and avoid shaking.

[0037] The shift lever 331 and the positioning plate 33 are connected in a quickly detachable manner. On both sides of the opening of the U-shaped structure on the positioning plate 33, grooves 332 are respectively provided. When the shift lever 331 is installed, both ends of the shift lever 331 are respectively arranged in the two grooves 332, and the side walls of the grooves 332 form a restriction on the shift lever 331 to restrict the lateral movement of the shift lever 331. The shift lever 331 can be separated from the positioning plate 33 vertically, so as to achieve quick disassembly and assembly. Further, a magnet 333 is provided at the bottom of the groove 332. The shift lever 331 is made of magnetic metal material. When the shift lever 331 is installed on the positioning plate 33, the magnet 333 generates a certain suction force on the shift lever 331 to maintain it in the groove 332 and prevent the shift lever 331 from falling off under the action of some external forces or equipment vibrations.

[0038] Further, in order to adapt to the installation of different models of sanding machines 34, the positioning plate 33 and the connecting plate 31 are detachably connected by bolts, so that when installing different models of sanding machines 34, a positioning plate 33 with different U-shaped structure sizes can be selected for installation.

[0039] Further, a load module is further provided on the upper part of the connecting plate 31. The load module includes a gravity block 351 and a jacking cylinder 352. The gravity block 351 is fixedly connected to the jacking cylinder 352. A slide rail is arranged vertically on the connecting plate 31. The jacking cylinder 352 is slidably connected to the chute and can move up and down along the chute. The telescopic end of the jacking cylinder 352 is fixedly connected to the top of the connecting plate 31 upward. When the jacking cylinder 352 drives the telescopic end to expand and contract, it drives the jacking cylinder 352 to move up and down along the chute, and correspondingly drives the gravity block 351 to move up and down. When the gravity block 351 abuts against the top of the sanding machine 34 downward, the further expansion and contraction amount of the jacking cylinder 352 can be used to adjust the thrust applied by the gravity block 351 to the sanding machine 34, so as to realize the adjustment of the load of the grinding wheel on the surface of the test consumable 2 and achieve different grinding effects.

[0040] Above the equipment cabinet 1, there is a bracket 5. On the bracket 5, there is a downward-facing lighting lamp 52 to provide illumination to the workbench surface 11. The control operation module is fixedly installed on the bracket 5. The control operation module includes an operation panel 51, and a touch display screen, an emergency stop switch, a pressing switch, a lighting switch, a main switch, and a start switch integrated on the operation panel 51. The emergency stop switch is used to control the emergency stop of the sander 34 and the clamping assembly 3. The pressing switch is used to control the action of the pressing cylinder 42. The lighting switch is used to control the on / off of the lighting lamp 52. The main switch is used to control the total power supply of the sander 34 load grinding test equipment. The start switch is used to control the on / off of the motor of the sander 34. Multiple adjustable parameters are displayed in the touch display screen, including the maximum speed of the clamping assembly 3 moving along the guide rail 321 and the adjustable speed range, adjustable distance range for reciprocating movement, cumulative grinding time and start / stop cycle of the sander 34, input of the running time and intermittent time of the sander 34, input of the on / off time of the test power supply, input of the start / stop time for single work, the pressure exerted by the load module on the sander 34, etc.

[0041] The clamping assembly 3 and the control operation module are electrically connected through wires to achieve signal transmission control between each module. A wire chain 511 is provided outside the wires for protection.

[0042] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
