Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a workpiece positioning auxiliary mechanism for vertical machining centers. Background Technology

[0002] Vertical machining centers are key metal cutting equipment in modern manufacturing, using high-speed rotating cutting tools to perform various precision machining operations on workpieces, such as milling, drilling, and boring. To ensure the machining accuracy of the final product, the workpiece must be accurately and reliably positioned and firmly clamped onto the machine tool's worktable before machining.

[0003] Currently, workpiece positioning typically relies on various specialized or general-purpose fixtures, such as manual vises, locating pins, and various adjustable stops or locating blocks. With the shift in manufacturing towards multi-variety, small-batch production, processing tasks frequently change, requiring repeated adjustments to positioning devices to accommodate workpieces of different sizes and shapes.

[0004] In traditional adjustment processes, operators typically need to use tools such as wrenches to first loosen the locking bolts of the positioning block, then manually tap or push it to its approximate position, perform fine-tuning and measurements, and finally tighten the bolts again after confirming the position is correct. This series of operations is not only cumbersome and time-consuming, but also completely dependent on manual operation, resulting in low adjustment efficiency and seriously affecting the effective processing time and overall production efficiency of the machine tool. Therefore, this utility model proposes a workpiece positioning auxiliary mechanism for vertical machining centers to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a workpiece positioning auxiliary mechanism for vertical machining centers, aiming to improve the problem of cumbersome operation when adjusting the positioning distance in some existing workpiece positioning mechanisms for vertical machining centers.

[0006] This utility model provides a workpiece positioning auxiliary mechanism for a vertical machining center, including: a sliding platform, and a modular positioning component detachably connected to the sliding platform; and a clamping mechanism slidably disposed on the inner wall of the modular positioning component.

[0007] The clamping mechanism includes a clamping block as the main operating component, a pinch block slidably connected to the inner wall of the clamping block, a locking plate fixedly connected to the bottom of the pinch block, and a reset component that provides reset force.

[0008] Furthermore, the spring in the reset assembly abuts against the locking plate. In its natural state, the elastic force of the spring pushes the locking plate to engage with the inner wall of the module positioning member to form a lock. When the pinch block is engaged, the locking plate is driven to overcome the reset force of the spring and move inward, thereby separating from the inner wall of the module positioning member, realizing unlocking, and allowing the clamping mechanism to slide and adjust along the inner wall of the module positioning member.

[0009] Preferably, the reset assembly further includes a limiting post, and a spring is fitted onto the outer wall of the limiting post. The limiting post provides a stable guide for the compression and reset process of the spring, preventing it from deflecting.

[0010] Preferably, the clamping block has two sets of mechanisms symmetrically arranged inside, consisting of pinch blocks, locking plates and reset components. The two sets of pinch blocks are arranged facing each other along the same horizontal line. This symmetrical structure makes the force more even when the operator pinches, ensuring the smoothness and synchronization of the unlocking and reset actions of the clamping mechanism.

[0011] Preferably, the inner wall of the module positioning component is also fixed with a sliding auxiliary groove, and the clamping mechanism also includes a sliding disk. The sliding disk is fixedly connected to the locking plate and slidably engaged in the sliding auxiliary groove. Through the cooperation of the guide rail and the slider, the smoothness and guiding accuracy of the clamping mechanism during sliding are further improved.

[0012] Preferably, the workpiece positioning auxiliary mechanism of the vertical machining center also includes a fixing mechanism, which is used to detachably lock the module positioning component to the sliding platform, thereby enabling rapid replacement of the entire positioning module.

[0013] In a further preferred embodiment, the fixing mechanism includes a handle, a slider fixedly connected to the handle, and a locking pin. The slider and the locking pin are connected in a transmission manner, so that the locking pin can be moved when the handle is pulled to release the locking of the module positioning component, thereby achieving tool-free unlocking.

[0014] Furthermore, the fixing mechanism also includes a main sliding column, a secondary sliding column, and a second spring. The main sliding column and the secondary sliding column are slidably disposed within the sliding platform and abut against the slider. The second spring is sleeved on the outer wall of the secondary sliding column and abuts against the slider, providing elastic force to automatically reset and lock the slider and locking column after the handle is released.

[0015] Preferably, the overall application environment of the workpiece positioning auxiliary mechanism of the vertical machining center also includes the machine tool housing and the machining platform. The machining platform is set inside the machine tool housing, and the table of the machining platform is equipped with slide rails. The sliding platform is slidably connected to the machining platform through the slide rails to realize the position adjustment of the entire auxiliary mechanism on the machine tool worktable.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a clamping mechanism, can drive the locking plate to overcome the spring force and unlock by squeezing the clamping block. After releasing, it will automatically reset and lock under the action of the spring. This solves the problems of cumbersome operation, reliance on tools and low efficiency of the positioning device in the prior art when adjusting the distance. It achieves the technical effect of quick and accurate fine adjustment of the positioning distance without tools, and significantly shortens the auxiliary time for changing workpieces.

[0018] 2. This utility model, by setting up a fixing mechanism, can drive the locking column to move by pulling the handle, so as to realize the quick disassembly and locking of the entire modular positioning component. It solves the problems of poor adaptability, limited adjustment range or complicated replacement process of traditional positioning devices when facing workpieces with huge size differences. It achieves the technical effect of modular quick replacement and greatly enhances the versatility and applicability of the device.

[0019] 3. This utility model combines a clamping mechanism with a small-range, rapid fine-tuning mechanism with a large-range, modularly replaceable fixing mechanism to achieve a dual adjustment mode. This solves the contradiction between adjustment efficiency and adjustment range that a single adjustment method cannot balance. It achieves the technical effect of compact overall structural design, flexible function, and intuitive operation, effectively reducing the skill requirements for operators.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Reference Figures 1 to 4 This utility model provides a workpiece positioning auxiliary mechanism for a vertical machining center, which aims to solve the problems of complex structure, cumbersome operation and low efficiency of existing workpiece positioning mechanisms for vertical machining centers when adjusting the positioning distance.

[0032] like Figure 1 As shown, the machine tool includes a machine tool housing 1 and a machining platform 2 disposed inside the machine tool housing 1. The table surface of the machining platform 2 is provided with a slide rail, and a sliding platform 3 is slidably connected to the machining platform 2 through the slide rail, thereby realizing coarse adjustment of the overall position. The sliding platform 3 is detachably connected to a modular positioning component 4, which serves as a replaceable functional base to adapt to positioning requirements of different specifications. The core innovation of this solution lies in the clamping mechanism 5, which is slidably disposed on the inner wall of the modular positioning component 4 to achieve rapid and precise positioning adjustment.

[0033] Reference Figure 2 and Figure 3 The clamping mechanism 5 includes a clamping block 51 as the main structure, and a pinching block 52 for the operator to pinch is slidably connected to the inner wall of the clamping block 51. A locking plate 55 is fixedly connected to the bottom of the pinching block 52. The locking plate 55 is used to engage or disengage with the inner wall of the module positioning member 4. The clamping mechanism 5 also includes a reset assembly 56, which includes a spring 562. The spring 562 abuts against the locking plate 55 and is used to always provide a reset force to move the locking plate 55 toward the module positioning member 4. In order to guide and limit the spring 562, the reset assembly 56 also includes a limiting post 561, and the spring 562 is sleeved on the outer wall of the limiting post 561.

[0034] The working process of the clamping mechanism 5 is as follows: In its naturally locked state, the restoring force of spring 562 pushes the locking plate 55, causing the locking plate 55 to engage with the inner wall of the module positioning member 4. At this time, the clamping mechanism 5 is locked and cannot slide. When the position needs to be adjusted, the operator pinches the pinch block 52 inward, and the pinch block 52 then drives the locking plate 55 to move inward synchronously. This movement process will overcome the restoring force of spring 562 and compress spring 562 until the locking plate 55 is completely separated from the inner wall of the module positioning member 4 and the lock is released. At this time, the entire clamping mechanism 5 can slide freely on the inner wall of the module positioning member 4 to adjust to the target position. To ensure the smooth and stable sliding process, a sliding auxiliary groove 53 is also fixed on the inner wall of the module positioning member 4. At the same time, the clamping mechanism 5 also includes a sliding disk 54 fixedly connected to the locking plate 55. The sliding disk 54 slides in the sliding auxiliary groove 53 to play a guiding and auxiliary role.

[0035] Reference Figure 1 and Figure 4 The fixing mechanism 6 includes a human-machine interface handle 61 for the operator to pull, and a slider 62 is fixedly connected to the handle 61. The slider 62 is slidably disposed inside the sliding platform 3. The fixing mechanism 6 also includes a locking post 66 for directly locking the module positioning component 4. The locking post 66 is connected to the slider 62 and moves synchronously under the drive of the slider 62. In order to provide reset capability and complete the entire linkage process, the fixing mechanism 6 also includes a main sliding post 63, a secondary sliding post 64 and a second spring 65. The main sliding post 63 and the secondary sliding post 64 are both slidably disposed inside the sliding platform 3 and abut against the outer end face of the slider 62. The second spring 65 is sleeved on the outer wall of the secondary sliding post 64 and abuts against the slider 62.

[0036] The process of unlocking the fixing mechanism 6 and replacing the module positioning component 4 is as follows: When the handle 61 is pulled outward, the handle 61 drives the slider 62 to slide outward synchronously; during the outward sliding process, the inner side of the slider 62 drives the locking pin 66 to move outward, so that the locking pin 66 disengages from the engagement state with the module positioning component 4, thereby releasing the lock; at the same time, the outer side of the slider 62 squeezes the main sliding pin 63 and the auxiliary sliding pin 64 to slide outward, and compresses the second spring 65 sleeved on the auxiliary sliding pin 64 to store energy for reset; when the handle 61 is released, the compressed second spring 65 releases its elastic force, pushes the slider 62 to reset inward, and then drives the locking pin 66 to re-insert and lock the new module positioning component 4. This structure realizes the function of quickly replacing the entire positioning module without tools, which greatly enhances the versatility and ease of operation of the device.

[0037] Reference Figure 3The reset assembly 56 also includes a limiting post 561, and a spring 562 is sleeved on the outer wall of the limiting post 561. The two ends of the limiting post 561 are respectively fixed to the inner wall of the clamping block 51, providing precise guidance for the compression and reset of the spring 562, and preventing it from lateral deflection or buckling when subjected to force.

[0038] Reference Figure 2 The clamping block 51 is symmetrically equipped with two sets of mechanisms consisting of pinch blocks 52, locking plates 55 and reset components 56. The two sets of pinch blocks 52 are arranged facing each other along the same horizontal line, so that when the operator pinches, the two locking plates 55 can retract inward or release outward synchronously, thereby avoiding motion jamming or mechanism deflection caused by unilateral force.

[0039] Reference Figure 2 and Figure 3 The inner wall of the module positioning component 4 is fixed with a sliding auxiliary groove 53. The clamping mechanism 5 also includes a sliding disk 54. The sliding disk 54 is fixedly connected to the locking plate 55 and its shape is adapted to the sliding auxiliary groove 53. The sliding disk 54 is slidably engaged inside the sliding auxiliary groove 53. When the clamping mechanism 5 slides as a whole, the sliding disk 54 moves in the sliding auxiliary groove 53, forming a cooperative relationship between the guide rail and the slider 62, which effectively reduces sliding resistance and ensures the straightness of the movement trajectory.

[0040] The implementation principle of this application embodiment is as follows: When a small-range precise positioning of the workpiece is required, the operator pinches the pinch block 52 set on the inner wall of the clamping block 51 inward. The pinch block 52 then drives the locking plate 55 fixedly connected to its bottom to move inward. This process will compress the spring 562 sleeved on the outer wall of the limiting post 561 and disengage the locking plate 55 from the inner wall of the module positioning member 4. At this time, the locking state of the entire clamping mechanism 5 is released, and the operator can push the clamping mechanism 5 to slide freely along the inner wall of the module positioning member 4 to the target position. After adjustment, the pinch block 52 is released, and the compressed spring 562 releases its elastic force, pushing the locking plate 55 to move in the opposite direction and re-engage with the inner wall of the module positioning member 4, thereby completing the positioning in a purely mechanical self-locking manner. The whole process does not require any tools and the operation is extremely fast.

[0041] When it is necessary to replace the modular positioning component 4 with a different specification to accommodate workpieces with large size differences, the operator pulls the handle 61 of the fixing mechanism 6 outward. The handle 61, through the slider 62 connected to it, drives the inner locking pin 66 to move outward, causing the locking pin 66 to disengage from the modular positioning component 4. As the slider 62 moves outward, it will squeeze the outer main sliding pin 63 and the secondary sliding pin 64, and compress the second spring 65 sleeved on the outer wall of the secondary sliding pin 64. At this time, the old modular positioning component 4 can be removed and replaced with the new modular positioning component 4. After the replacement is completed, the handle 61 is released, and the compressed second spring 65 pushes the slider 62 to return to its original position inward. The slider 62 then drives the locking pin 66 to re-insert and lock the new modular positioning component 4, realizing the rapid replacement of modular components.
