[0040] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0041] This embodiment proposes a multi-hole adjustable spacing worktable, such as... Figure 1-3 As shown, the system includes a frame 10, a platform unit 30 positioned above the frame 10, a drive unit 20 located inside the frame 10, and an adjustable unit positioned outside the frame 10. The frame 10 has a guide rail 11 and a slider 12 that cooperates with the guide rail 11 along its length. The drive unit 30 includes a motor 31 and a conveyor belt 32 parallel to the guide rail 11, with a pressure plate 33 mounted on the conveyor belt 32. The platform unit 20 includes a fixed plate 21 fixedly mounted on the frame 10 and a movable plate 22 positioned above the fixed plate 21. The movable plate 22 passes through the fixed plate 21 and is connected to the top surface of the slider 12 and the top and sidewall surfaces of the pressure plate 33, respectively. The adjustable unit includes a scale assembly 40 and a switch assembly 50 located on the outer edge of the frame 10. The motor 31 drives the transmission belt 32 through the pressure plate 33 to move the moving plate 22 and the slider 12 together along the guide rail 11, and moves on the scale assembly 40 based on the preset hole spacing adjustment conditions, so as to drive the binding material to perform corresponding single hole or multi hole operations.

[0042] like Figure 2 As shown, the frame 10 is a support made of several iron frames welded together. Its head is located near the scale assembly 40, and its tail is an open structure. The guide rail 11 is located at the top of the frame 10. The slider 12 has a U-shaped cross-section, and its open side is fixed to the guide rail 11 and faces the conveyor belt 32.

[0043] The conveyor belt 32 is located inside the guide rail 11, and the motor 31 is fixed to the frame 10 and located at one end of the width of the frame 10. The scale assembly 40 is fixed to the fixed plate 21, and the switch assembly 50 is located below the guide rail 11 and on one side of the bottom height of the frame 10. Part of the photoelectric switch of the switch assembly 50 is fixed to the frame 10, and part of the photoelectric switch is connected to the movable moving plate 22.

[0044] like Figure 1 and Figure 4 As shown, in the table unit 20, the fixing plate 21 is a flat surface for placing the binding material. It is positioned between the frame 10 and the movable plate 22 and is fixed to the top surface of the frame 10. The top of the fixing plate 21 has several parallel elongated circular holes arranged along the length of the guide rail 11, and the side closer to the guide rail 11 is mainly used to install the movable plate 22 and move the movable plate 22 horizontally along the length of the elongated circular holes; and the movable plate 22 passes through these elongated circular holes and is directly connected to the pressure plate 33 and the slider 12.

[0045] The fixing plate 21 is constructed as a zigzag surface, with its large section horizontally and straightly fixed to the top of the frame 10, and its small section vertically bent downwards and placed on one side of the location of the scale assembly 40, and the zigzag angle of the zigzag surface is 90°; the scale assembly 40 is fixedly installed on the vertical surface of the small section.

[0046] like Figure 4-5 As shown, the movable plate 22 is constructed as a planar L-shaped structure. One end of one section is connected to the top of the slider 12, and the other section has several elongated holes parallel to the guide rail 11. These elongated holes are located near the drilling or riveting side. The elongated holes and elongated circular holes are positioned on both sides of the width of the fixed plate 21. The fixed plate 21 also has elongated grooves that mate with the elongated holes. The driven movable plate 22 can slide horizontally along the length of the elongated grooves via connecting members. A positioning block 23 is constructed on the movable plate 22 that slides into the elongated holes. The elongated grooves that mate with the elongated holes allow the movable plate 22 to protrude from the fixed plate 21, so that the positioning block 23 and the movable plate 22 can move the binding material horizontally without obstruction on the fixed plate 11.

[0047] Preferably, on the side of the movable plate 22 near the slider 12, that is, near the extension 24 integrally bent downwards from the switch assembly 50, the extension 24 passes through the fixed plate 21 and is directly connected to the vertical side of the movable plate 12, and the width of the extension 24 is smaller than the width of the unidirectional segment of the movable plate 22.

[0048] like Figure 3 As shown, in the drive unit 30, the motor 31 and the switch assembly 50 are respectively placed at both ends of the length of the frame 10; the transmission belt 32 is a toothed belt, which is located inside the guide rail 11, and the motor 31 is located on the side of the transmission belt 32 away from the guide rail 11. The drive unit 30 also includes a main synchronous pulley and a driven synchronous pulley that cooperate with the transmission belt 32. The main synchronous pulley is directly connected to the output end of the motor 31, and the driven synchronous pulley is located on the side away from the motor 31. Both the main synchronous pulley and the driven synchronous pulley are located on the side facing the guide rail 11, and the diameter of the main synchronous pulley is larger than the diameter of the driven synchronous pulley, which can further reduce its installation area and increase the occupied area of ​​the internal space of the frame 10.

[0049] like Figure 6-7As shown, the scale assembly 40 includes a scale 41 and a guide groove 42 arranged parallel to the guide rail 11. The guide groove 42 is located below the scale 41 and is fixed to the outer side of a small section of the fixing plate 21. A left indicator plate 43 and a right indicator plate 44 for adjusting the hole spacing are provided outside the scale 41. Both the left and right indicator plates 43 and 44 are connected to a left bracket 45 and a right bracket 46 located on the back of the guide groove 42 via two independently disposed T-blocks within the guide groove 42. The left and right indicator plates 43 and 44 are fixed to the T-blocks by a fixing knob, which can be manually controlled to adjust the position of the two indicator plates. The positions of the left and right indicator plates 43 and 44 are manually adjustable and are independent of the position of the moving plate 22.

[0050] like Figure 8 The diagram shows a perspective view of the left bracket 45. The right bracket 46 has the same structure as the left bracket 45. The explanation will focus on the structural view of the left bracket 45. The left bracket 45 includes a right-angled folded plate body structure. Two fixing knob mounting holes are provided on one side near the guide groove 42. A horizontally arranged signal baffle is provided on the back side of the fixing knob mounting holes, mainly used to cooperate with the left photoelectric switch 51 and the right photoelectric switch 52 in the switch assembly 50, triggering the signal of the left photoelectric switch 51 and / or the right photoelectric switch 52. A vertically extending wing is provided at the top of the left bracket 45, mainly used to cooperate with the positioning photoelectric switch 54 fixedly connected to the extension section 24 to trigger the signal of the positioning photoelectric switch 54. The wing in the left bracket 45 and the wing in the right bracket 46 are located at adjacent ends of the folded plate body.

[0051] like Figure 5 As shown, the switch assembly 50 includes a left photoelectric switch 51 and a right photoelectric switch 52 that cooperate with the left bracket 45 and / or the right bracket 46, an initial photoelectric switch 53 and a positioning photoelectric switch 54 arranged vertically. The left photoelectric switch 51, the right photoelectric switch 52 and the initial photoelectric switch 53 are all fixed to the lower left side of the end of the frame 10 by a fixing plate, and all their positions are fixed. The positioning photoelectric switch 54 is fixed to the extension section 24 and can move with the movement plate 22. The positioning photoelectric switch 54 is arranged downwards and mainly cooperates with the wing strips in the left bracket 45 and the right bracket 46 to trigger the signal of the positioning photoelectric switch 54, the purpose of which is to determine the position of the second or third hole in the two-hole mode or the three-hole mode.

[0052] The left photoelectric switch 51 and the right photoelectric switch 52 are horizontally fixed to the frame 10 by a fixing plate, and both are set in the direction of the left bracket 45 and the right bracket 46.

[0053] The initial photoelectric switch 53 is fixed to the frame 10 by a vertical fixing plate, and is set vertically upward. The width of the extension section 24 is greater than the width of the mounting strip used to fix and position the photoelectric switch 54, and its height is also greater than the height of the slider 12. The overhang angle of the extension section 24 near the initial photoelectric switch 53 cooperates with the initial photoelectric switch 53 to trigger the signal of the initial photoelectric switch 53.

[0054] The workbench in this application can continuously operate under different binding modes, but users need to manually set the mode on the control panel. Specifically, they need to set the binding mode on-site: single-hole, double-hole, or triple-hole. If it's double-hole or triple-hole, the spacing between adjacent holes also needs to be set. After one mode is completed, the mode can be readjusted to operate on the next set of different modes. Alternatively, binding can be performed continuously using the same mode. Details are as follows:

[0055] When powered on, press the reset button on the operation panel (attached image omitted). Motor 31 will drive the moving plate 22 to move closer to the initial position until the extension section 24 touches the initial photoelectric switch 53, ending the reset. At this time, if... Figure 2 As shown, the left bracket 45 and the right bracket 46 are respectively matched with the left photoelectric switch 51 and the right photoelectric switch 52, and the right indicator plate 44 points to the zero position on the scale 41.

[0056] like Figure 1 As shown, place the binding material onto the movable plate 22, determine the position where the binding material needs to be drilled or riveted, adjust the positioning block 23, and lock it.

[0057] If the system is set to single-hole binding mode, meaning there is only one position for drilling or riveting on the binding material, then there is no need to move the binding material or the moving plate; drilling or riveting can be performed directly on the binding material. In this case, the left bracket 45 and right bracket 46 touch the left photoelectric switch 51 and right photoelectric switch 52 respectively without triggering, and the right indicator plate 44 remains stationary at the zero position of the scale 41. Simultaneously, the extension section 24 is embedded in the initial photoelectric switch 53 and does not trigger.

[0058] After this binding is completed, if you want to continue working in the double-hole binding mode, there is no need to adjust the positions of the left indicator plate 43 and the right indicator plate 44. Simply repeat the above steps. If you want to change the binding mode, simply adjust the positions of the left indicator plate 43 and / or the right indicator plate 44 using the fixing knob, and then perform drilling or riveting work on the next bound item.

[0059] If the system is set to a dual-hole binding mode, meaning there are two locations on the bound item where holes are drilled or riveted, first manually adjust the fixing knob on the right indicator plate 44, and move its position along the length of the scale 41 from 0mm to any position between 200mm and the second hole. The knob can be set arbitrarily, and stop when it reaches the location of the second hole.

[0060] When the right bracket 46 moves away from the right photoelectric switch 52, triggering the signal of the right photoelectric switch 52, and the left bracket 45 remains fixed and does not trigger its signal, the system knows that this operation is a dual-hole mode. After adjustment, press the start button on the control panel to directly perform drilling or riveting at the first position.

[0061] After the first drilling or riveting operation is completed, the motor 31 starts working automatically and drives the conveyor belt 32 to rotate. The belt pressure plate 33 drives the moving plate 22 to continue moving to the right, which in turn drives the positioning photoelectric switch 54 to move to the right along with the moving plate 22. When the positioning photoelectric switch 54 touches the right support 46, it triggers a signal, causing the motor to stop, the moving plate to stop, and the drilling or riveting operation for the second position on the bound item to begin.

[0062] After the drilling or riveting action at the second position is completed, the moving plate 22 is driven by the motor 31 through the pressure plate 33 to move to the left and in the opposite direction until the extension section 24 touches the initial photoelectric switch 53, triggering the initial photoelectric switch 60 signal, that is, resetting to the initial position, and the moving plate 22 stops.

[0063] After this binding is completed, if you want to continue working in the double-hole binding mode, there is no need to adjust the positions of the left indicator plate 43 and the right indicator plate 44. Simply repeat the above steps. If you want to change the binding mode, simply adjust the positions of the left indicator plate 43 and / or the right indicator plate 44 using the fixing knob, and then perform drilling or riveting work on the next bound item.

[0064] If the system is set to a three-hole binding mode, meaning there are three locations on the bound item for drilling or riveting, first manually adjust the fixing knobs on the right indicator plate 44 and the left indicator plate 43, and move their positions sequentially from 0mm to any position between 200mm and 0mm along the length of the scale 41. These positions can be freely set according to individual needs. Stop when the right indicator plate 44 is at the location of the third hole and the left indicator plate 43 is at the location of the second hole.

[0065] When the right bracket 46 moves away from the right photoelectric switch 52 and the left bracket 45 moves away from the left photoelectric switch 51, the signals of the right photoelectric switch 52 and the left photoelectric switch 51 are triggered respectively, and the system then knows that the current operation is in three-hole position mode. After the adjustment is completed, press the start button on the control panel to directly perform drilling or riveting in the first position.

[0066] After the first hole or riveting is completed, the motor 31 starts working automatically and drives the conveyor belt 32 to rotate. The belt pressing plate 33 drives the moving plate 22 to continue moving to the right, which in turn drives the positioning photoelectric switch 54 to move to the right along with the moving plate 22. The positioning photoelectric switch 54 will first touch the left bracket 45, i.e., the second hole position. At this point, the signal of the positioning photoelectric switch 54 is immediately triggered, the motor stops working, the moving plate stops, and the second hole or riveting operation begins on the bound item.

[0067] After the second drilling or riveting operation is completed, motor 31 starts working automatically and drives conveyor belt 32 to rotate. This drives moving plate 22 to the right via pressure plate 33, which in turn moves positioning photoelectric switch 54 to the right along with moving plate 22. Positioning photoelectric switch 54 finally touches the right bracket 45, i.e., the third hole position. At this point, the signal from positioning photoelectric switch 54 is immediately triggered, the motor stops working, the moving plate stops, and the drilling or riveting operation for the third position on the bound item begins.

[0068] After the drilling or riveting action at the third position is completed, the moving plate 22 is driven by the motor 31 through the pressure plate 33 to move to the left in the opposite direction until the extension section 24 touches the initial photoelectric switch 53, triggering the initial photoelectric switch 60 signal, that is, resetting to the initial position, and the moving plate 22 stops.

[0069] After this binding is completed, if you want to continue working in the three-hole binding mode, there is no need to adjust the positions of the left indicator plate 43 and the right indicator plate 44. Simply repeat the above steps. If you want to change the binding mode, simply adjust the positions of the left indicator plate 43 and / or the right indicator plate 44 using the fixing knob, and then perform drilling or riveting work on the next item to be bound.
