Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a quick positioning and locking device for a horizontal machining center worktable. Background Technology

[0002] In the field of machining, horizontal machining centers require extremely high positioning accuracy and locking stability of the worktable, directly affecting the machining quality and production efficiency. Traditional worktable positioning and locking devices have many shortcomings:

[0003] On the one hand, the positioning process often relies on manual adjustment or complex transmission mechanisms, resulting in slow positioning speed and low accuracy, making it difficult to meet the needs of high-efficiency processing. On the other hand, the locking mechanism often suffers from insufficient clamping force or uneven force, which makes the workpiece prone to displacement during processing. At the same time, some devices lack effective braking and heat dissipation structures, affecting the reliability and service life of operation.

[0004] A search revealed existing technology (application number: CN222971653U), which describes "a horizontal machining center." This utility model uses a fixture to fix mechanical parts, with an operator corresponding to the mechanical parts on the fixture. Simultaneously, the fixture box and related structures assist in fixing, ensuring the stability of the parts' position during machining.

[0005] However, the device lacks a rapid positioning and secure locking structure for the processed parts, resulting in deficiencies in processing accuracy and stability. Utility Model Content

[0032] Example 1:

[0033] like Figures 1 to 4 As shown, this embodiment provides a quick positioning and locking device for a horizontal machining center worktable, comprising: a base 1 with a sliding groove; an adjusting assembly 2 including a slider 24, which is slidably connected to the sliding groove of the base 1, and the slider 24 having four sliders and a through hole in the middle; and a fixing assembly 3 including a support shaft 31, a support sleeve 32, a connecting shaft 33, and a clamping plate 37. The support shaft 31 is welded to the slider 24, and two of them are threaded. The support sleeve 32 is threadedly connected to the threaded support shaft 31 and slidably connected to the other two support shafts 31. The bottom end of the connecting shaft 33 is rotatably connected to the support sleeve 32. The clamping plate 37 is slidably connected to the connecting shaft 33.

[0034] In addition, two of the support sleeves 32 are provided with anti-slip textures.

[0035] One side of the clamping plate 37 is connected to an elastic washer by bolts.

[0036] Specifically, mounting holes 11 are provided on the side wall of the base 1, a support column is welded to the bottom of the base 1, a mounting plate is welded to the bottom of the support column, and mounting holes 11 are provided on the mounting plate.

[0037] Specifically, a positioning block 12 is welded to the middle of the upper part of the base 1, and the positioning block 12 is used to place objects.

[0038] In some embodiments, the items that this device is suitable for processing can be box-type or shell-type workpieces, such as engine blocks and gearbox housings. Figure 1 In this embodiment, the processed item is described as a box-shaped workpiece. Of course, other types of processed items can also adopt a similar structure, which will not be repeated hereafter.

[0039] Understandable Figure 1 The diagram only schematically illustrates some of the components included in a horizontal machining center; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, horizontal machining centers can also include, compared to... Figure 1 More or fewer parts.

[0040] In this embodiment, the base 1, the adjustment component 2, and the fixing component 3 constitute a quick positioning and locking device for a horizontal machining center worktable according to this application.

[0041] Example 2:

[0042] Specifically, the adjustment component 2 also includes: a drive motor 21, which is connected to the bottom of the base 1 through a housing, and the bottom of the housing is provided with heat dissipation holes; a transmission gear 22, which is keyed to the output shaft of the drive motor 21; and a transmission rack 23, of which there are two, one end of which is welded to the slider 24 through a connecting block, and the connecting block is welded to the bottom of the two sliders 24 and meshes with the transmission gear 22.

[0043] Specifically, the adjustment assembly 2 also includes: an electromagnetic brake 25, which is shaft-connected to the output shaft of the drive motor 21; and a fan 26, which is bolted to the top of the housing.

[0044] It should also be noted that the controller is located on the side wall of the base 1 and is electrically connected to the drive motor 21, the electromagnetic brake 25 and the fan 26.

[0045] In this embodiment, the drive motor 21 drives the transmission gear 22 to rotate, the transmission gear 22 drives the transmission rack 23 to move, and then drives the slider 24 to move, so as to realize the automatic adjustment and movement of the slider 24. The electromagnetic brake 25 locks the output shaft when the drive motor 21 stops. The fan 26 dissipates heat inside the housing to prevent the slider 24 from moving accidentally and to ensure the normal operating temperature of the drive motor 21.

[0046] Example 3:

[0047] Specifically, the fixing component 3 also includes: a support spring 34, with its two ends welded to the support sleeve 32 and the clamping plate 37 respectively; a rotating rod 35, welded to the top of the connecting shaft 33 and located above the clamping plate 37; and wedge blocks 36, welded to both ends of the rotating rod 35.

[0049] In addition, arrows are provided on the guide post 38.

[0050] In this embodiment, rotating the rotating rod 35 drives the wedge block 36 to rotate, squeezing the clamping plate 37. The support spring 34 provides a reverse force to enhance the clamping force on the object. The guide post 38 slides along the through hole of the slider 24 and the pad 39 to limit the movement direction of the clamping plate 37, ensuring the stable movement of the clamping plate 37 and improving the clamping accuracy.

[0051] In actual use, the operator first places the object to be processed on the positioning block 12, and then starts the drive motor 21 and fan 26 through the controller. The drive motor 21 drives the transmission gear 22 to rotate, the transmission gear 22 drives the transmission rack 23 to move, and the transmission rack 23 drives the slider 24 to slide along the groove of the base 1 to adjust the distance between the two sliders 24, so that the pad 39 moves to the lower surface of the object. Then, the support sleeve 32 is rotated to lower the clamping plate 37 until the arrow is in contact with the upper surface of the object. Then, the rotating rod 35 is rotated, and the rotating rod 35 drives the wedge block 36 to rotate. The wedge block 36 presses the clamping plate 37 to the upper surface of the object to fix the object.

[0052] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power.
