[0002] Grooving is the front process of some metal workpieces that require arc radius or right-angle bending. Grooving requires a groover. Existing groovers include single-head groovers, double-head groovers, and four-head groovers. Whether it is a groover with two or four cutter heads, the position between the cutter heads is generally fixed, that is, the cutter heads can only be adjusted up and down and left and right, and cannot be adjusted front and back. The cutter heads of this structure can either only open one groove or two grooves with non-adjustable distances during one movement. It is not suitable for workpieces with different groove opening requirements. In order to solve the above problems, , slotting machines with adjustable cutter head distance have gradually appeared on the market. One of the tool holders is fixed, and the other tool holder can be moved back and forth as needed.

The front tool holder mechanism 5 and the rear tool holder mechanism 6 and the rear driving guide component are both arranged in the mounting frame 12. The front tool holder mechanism 5 and the rear tool holder mechanism 6 can move forward and backward relative to the workbench 11 under the action of the front guide component and the rear guide component respectively. The mounting frame 12 is provided with a slider group matching the linear guide rail. In this embodiment, the linear guide rail on the upper guide rail seat 2 includes a first linear guide rail and a second linear guide rail. The first linear guide rail is arranged at the bottom of the upper guide rail seat, and the second linear guide rail is arranged on the side of the upper guide rail seat. The slider group includes tool holder sliders respectively matched with the first linear guide rail and the second linear guide rail, thereby ensuring the firmness of the tool holder assembly installation and the stability during movement.

[0027] The working principle of the slotting machine of the present invention is as follows: a workpiece to be slotted is placed on the workbench 11, the equipment is turned on, the fixed pressure plate group 8 is used to press the workpiece, the tool holder assembly 56 is adjusted to the processing starting position in the left and right directions by the driving part 23, the front driving guide component and the rear driving guide component are started, and the front tool holder mechanism 5 and the rear tool holder mechanism 6 are respectively moved forward and backward to above the position to be slotted, and then the height of the tool head in the front tool holder mechanism 5 and the rear tool holder mechanism 6 is adjusted according to the requirement of the slotting depth, and the follower pressure plate group 7 is moved forward and backward to the set position and then presses the workpiece, and the front tool holder mechanism 5 and the rear tool holder mechanism 6 start a slotting work of a stroke under the action of the driving force, and two grooves can be opened at one time. After one slotting is completed, if multiple grooves need to be opened on the same workpiece, there is no need to move the workpiece, and only the position of the tool holder assembly 56 and the follower pressure plate group 7 needs to be adjusted to perform slotting at another position.

[0028] The slotting machine of the present invention can realize the effect of opening two slots in one moving stroke through the front tool holder mechanism 5 and the rear tool holder mechanism 6 which can move forward and backward and adjust the front-to-back distance therebetween. It can be used for workpieces with different requirements for the distance between the two slots, and there is no need to change the tool holder assembly. Through cooperation with the follow-up pressure plate group 7, multiple grooves can be opened on the workpiece without moving the workpiece, which greatly improves work efficiency and saves labor costs.

[0029] In the prior art, the workbench is fixed to the base by several bolts. Such a connection method easily makes the workbench surface uneven. Especially after being used for a long time, it is easy to be uneven due to wear and tear and excessive compression, which can easily cause the accuracy of planing to be greatly reduced. In this embodiment, Figure 6-7 As shown, a plurality of adjustment holes 111 are provided at the bottom of the workbench 11, and a plurality of threaded holes 112 matching the adjustment holes 111 are provided on the base 1. When the surface of the workbench 11 is uneven, it can be adjusted by adjusting the bolts at the corresponding adjustment holes 111. No matter how long the equipment is used, the flatness of the surface of the workbench 11 can be adjusted to ensure the accuracy of the planing grooves.

[0030] Among them, a positioning block for limiting the workpiece is also arranged in front of the workbench 11. The positioning block includes a single workpiece positioning block 9 and a double workpiece positioning block 10. When the workpiece is placed, it is used to position the workpiece to ensure the accuracy of the planing position.

[0031] Among them, Figure 5 As shown, the follower pressure plate group 8 includes a base 81, a plurality of movable presser feet 82 and a driving assembly, wherein the driving assembly is fixed on the base 81, the driving assembly is connected to the movable presser foot 82 and drives the movable presser foot 82 to rise and fall, the longitudinal sliding assembly includes a longitudinal slide rail 88 and a longitudinal slider 89, the base 81 is fixed on the longitudinal slider 89, the longitudinal slide rail 88 is arranged on the base 1, and its setting direction is consistent with the direction of the movable presser foot 82, the base 81 moves forward and backward on the longitudinal slide rail 88 with the movable presser foot 82, ensuring that all the movable presser feet 82 move together, and a second driving member 16 for driving the follower pressure plate group 8 to move forward and backward is arranged on the base 1, when it is necessary to adjust the follower pressure plate group 8 to move, the second driving member 16 is started to make the longitudinal slider 89 on the base 81 slide on the longitudinal slide rail 88.

[0032] Among them, the movable presser foot 82 is connected with a presser foot connecting plate 83, and the presser foot connecting plate 83 is connected to the base 81 through a vertical sliding assembly. The presser foot connecting plate 83 drives the movable presser foot 82 to move straight up and down above the workpiece, that is, the movable presser foot 82 is no longer lifted up and pressed down by rotation like the previous presser foot. The straight up and down movement of the movable presser foot 82 can make it closer to the planing tool, which is suitable for the processing of small-sized workpieces.

[0033] In this embodiment, in order to further ensure the balance of the movable presser foot 82, the base 81 is a plate frame structure, and the plate frame structure is provided with a plurality of through holes through which the movable presser foot 82 passes. The vertical sliding assembly includes a vertical guide rail 85 arranged on the base 81 and a vertical slider 810 arranged on the pressure plate connecting plate 83 and matching the vertical guide rail 85. The driving assembly drives the lifting and lowering of the movable presser foot 82, and the pressure plate connecting plates 83 on both sides of the base 81 move vertically along the base plate 81, thereby ensuring the balance and stability of the movable presser foot 82 during the lifting process, and also ensuring the vertical movement of the movable presser foot 82, so that it can be closer to the planing tool.

[0034] Among them, the driving component includes a pressure cylinder 86 and an elastic element 87, and the pressure cylinder 86 and the elastic element 87 are both fixed in the base 81. The bottom of the pressure cylinder 86 abuts against the top of the movable presser foot 82. When the pressure cylinder 86 outputs pressure, it drives the movable presser foot to move downward to press the workpiece. The top of the elastic element 87 abuts against the bottom of the movable presser foot 82. When the pressure of the pressure cylinder 86 is eliminated, the elastic element 87 returns to its position upward under the action of the rebound force, and the workpiece is released.

[0035] Among them, Figure 3-4 As shown, the front tool holder mechanism 5 includes a front sliding base 52, a front base 51 and a front tool body 55. The front driving guide component includes a front driving screw 58 and a front sliding guide column 56 longitudinally arranged on the mounting frame 12. The front sliding guide column 56 plays a guiding and supporting role. The front driving screw 58 is arranged on the top of the front sliding base 52 through a nut fixing seat 59. The front sliding base 52 slides back and forth along the front sliding guide column 56 under the action of the front driving screw 58. The front base 51 is vertically arranged at the bottom of the front sliding base 52. The front tool body 55 is slidably arranged in the front base 51. When working, the front driving screw 58 drives the front sliding base 52 to move back and forth along the front sliding guide column 56.

[0036] During the grooving process, the workpiece will give a reaction to the front tool holder mechanism 5, which may easily cause the front sliding guide column 56 to deform, and easily lead to the front tool holder mechanism 5 not being able to grooving accurately enough, seriously affecting the product quality. To solve the above problem, a first guide rail 53 is also provided on the mounting frame 12. The first guide rail 53 can not only allow the front sliding base 52 to slide thereon, but also receive the reaction force given by the workpiece, thereby avoiding the deformation of the front sliding guide column 56 and improving the accuracy of the processed products.

[0037] In this embodiment, the structure of the rear tool holder mechanism 6 is the same as that of the front tool holder mechanism 5, including a rear sliding base 62, a rear base 61 and a rear tool body 65. The rear drive guide component includes a rear drive screw 68 and a rear sliding guide column 66 longitudinally arranged on the mounting frame 12. The rear drive screw 68 is arranged on the top of the rear sliding base 62 through a nut fixing seat 69. The rear sliding base 62 slides back and forth along the rear sliding guide column 66 under the action of the rear drive screw 68. The rear base 61 is vertically arranged at the bottom of the rear sliding base 62. The rear tool body 65 is slidably arranged in the rear base 61. During operation, the rear drive screw 68 drives the rear sliding base 62 to move back and forth along the rear sliding guide column 66. A second guide rail 63 for the sliding of the rear sliding base 62 is also arranged on the mounting frame 12.
