Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment manufacturing technology, and in particular to a fixture rack for quick tool change. Background Technology

[0002] In the field of machining, fixture racks are indispensable auxiliary equipment, playing a vital role in storing the tools required for machining. Whether it is milling or turning precision parts, or drilling or grinding heavy workpieces, all kinds of machining tools need to be stored in an orderly manner and easily accessible. From small tool racks next to CNC lathes to multi-layer three-dimensional fixture racks in large machining workshops, machining tools of different specifications and uses are classified and stored, enabling operators to quickly locate and obtain the required tools in complex machining processes, significantly improving production efficiency and reducing machining errors caused by tool disorder.

[0003] However, after the operator finishes machining the part, the cylindrical tools are placed directly on the shelf. Although these tools can remain relatively stable when stationary, avoiding the problem of tools being scattered randomly on the workbench and causing space disorder, the existing solution is to design grooves on the shelf to limit the position of the tools. However, although the grooves can limit the position of the tools, the vibration of the shelf caused by repeated handling will cause the tools to slip off the shelf without being fixed. At the same time, the friction and wobbling inertia between the tools and the shelf will cause the positions of adjacent tools to shift. As the number of operations increases, the tools on the entire fixture rack become disorderly, which seriously affects the efficiency of retrieval. Therefore, a fixture rack for quick tool replacement is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick tool change fixture rack, which aims to improve the problem in the prior art that cylindrical tools cannot be effectively placed, resulting in friction and wobbling inertia between the tool and the rack, causing the tool to shift and fall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-change tool clamp rack, comprising multiple rack plates, multiple placement cylinders fixedly connected to the top of the rack plates, mounting grooves opened on the left and right sides of the outer wall of the placement cylinders, a rotating shaft two rotatably connected to the inner side of the mounting grooves, a clamping plate fixedly connected to the outer wall of the rotating shaft two, rubber blocks fixedly connected to adjacent sides of two clamping plates, a pressing plate fixedly connected to the bottom end of two clamping plates, and torsion springs fixedly connected to the front and rear ends of the outer wall of the rotating shaft two. An anti-pickup component is provided on the top of the rack plate, and a splicing mechanism is provided at the bottom of the rack plate. The splicing mechanism is used to freely stack multiple sets of rack plates.

[0006] As a further description of the above technical solution:

[0007] The splicing mechanism includes multiple plug-in cylinders, which are fixedly connected to the four corners of the top of the frame plate. Each plug-in cylinder has a plug-in slot at its top and a support column at its bottom. Two rotating shafts are rotatably connected to the left and right sides of the frame plate. A locking plate is fixedly connected to the outer wall of the rotating shaft. Two locking columns are fixedly connected to the left and right sides of the frame plate. Bolts are threaded to the far ends of the locking columns, and reinforcing plates are fixedly connected to the outer walls of the bolts.

[0008] As a further description of the above technical solution:

[0009] The protective assembly includes multiple partitions, the bottoms of which are fixedly connected to the top of the frame plate.

[0010] As a further description of the above technical solution:

[0011] The splicing mechanism also includes a rubber pad, the bottom of which is fixedly connected to the bottom of the insertion slot.

[0012] As a further description of the above technical solution:

[0013] The partitions are arranged at equal intervals, and rubber strips are fixedly connected to the left and right sides of each partition.

[0014] As a further description of the above technical solution:

[0015] The bottom of the frame plate is equipped with casters at all four corners, and brakes are installed on the outer wall of the casters.

[0016] As a further description of the above technical solution:

[0017] Multiple label plates are fixedly connected to the top front side of the shelf, and a transparent window is fixedly connected to the top of the label plates.

[0018] As a further description of the above technical solution:

[0019] Handles are fixedly connected to both the left and right sides of the shelf, and anti-slip sleeves are fixedly connected to the outer walls of the handles.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the tool is placed between the extrusion plates, the extrusion plates will squeeze and rotate to both sides, while simultaneously driving the clamping plate to clamp inward, so that the rubber block fits into the surface of the tool, completing a quick clamping and fixing. When the tool is taken out, the clamping plate will return to its original position under the rebound of the torsion spring, which facilitates subsequent use, avoids tool shaking, and makes taking out more convenient.

[0022] 2. In this utility model, when stacking multiple sets of racks, the support column is inserted into the corresponding insertion slot to complete the initial splicing process. At the same time, the locking plate is rotated upward and locked onto the locking column.

Multiple placement cylinders 3 are fixedly connected to the top of each rack plate 1. The placement cylinders 3 are equidistantly fixed on the rack plates 1. The inner diameter of each placement cylinder 3 can be fixed on different rack plates 1 to accommodate tools of different diameters. Mounting grooves 4 are provided on the left and right sides of the outer wall of each placement cylinder 3. A rotating shaft 5 is rotatably connected to the inner side of each mounting groove 4. A clamping plate 6 is fixedly connected to the outer wall of the rotating shaft 5. The clamping plates 6 are installed in the corresponding mounting grooves 4 via the rotating shafts 25 on both sides. The clamping plates 6 are located on both sides of the placement cylinder 3. Rubber blocks 7 are fixedly connected to adjacent sides of two clamping plates 6. Extrusion plates 9 are fixedly connected to the bottom ends of two clamping plates 6. The clamping plates 6 and rubber blocks 7 are... The rubber block 7 and the extrusion plate 9 are integrally formed. The front and rear ends of the outer wall of the rotating shaft 5 are fixedly connected with torsion springs 8. At the same time, the torsion springs 8 can improve the clamping force. The clamping plate 6 will complete the reset under the rebound of the torsion springs 8. The top of the rack plate 1 is provided with an anti-pickup component, and the bottom of the rack plate 1 is provided with a splicing mechanism 2. The splicing mechanism 2 is used to freely stack multiple rack plates 1. The anti-pickup component includes multiple partitions 12. The bottom of the multiple partitions 12 is fixedly connected to the top of the rack plate 1. The multiple partitions 12 are arranged at equal intervals. Rubber strips 13 are fixedly connected to the left and right sides of the partitions 12. The partitions 12 are fixed on both sides of the placement cylinder 3. This not only improves the classification of tools, but also prevents the tools from being bumped during the handling process.

[0032] Specifically, the placement cylinders 3 are equidistantly fixed on the frame plate 1. The placement cylinders 3 have different inner diameters and are fixed on different frame plates 1 to accommodate tools of different diameters. The clamping plates 6 are installed in the corresponding mounting slots 4 via the two rotating shafts 5 on both sides. The clamping plates 6 are located on both sides of the placement cylinders 3. The clamping plates 6, rubber blocks 7, and extrusion plates 9 are integrally formed. When a tool is placed between the extrusion plates 9, the extrusion plates 9 rotate to both sides, simultaneously causing the top clamping plates 6 to clamp inwards, making the rubber blocks 7 fit against the surface of the tool, thus achieving rapid clamping and fixing. The outer wall of the rotating shaft 5... Torque springs 8 are fixed at both the front and rear ends. Torque springs 8 not only improve the clamping force but also make it easier to pick up. After picking up, the clamping plate 6 will be reset under the rebound force of the torsion springs 8, which is convenient for subsequent use. The anti-pickup component includes multiple partitions 12. The bottom of the multiple partitions 12 is fixed to the top of the frame plate 1. The multiple partitions 12 are arranged at equal intervals. Rubber strips 13 are fixed on the left and right sides of the partitions 12. The partitions 12 are fixed on both sides of the placement cylinder 3. This not only improves the classification of tools but also prevents the tools from being bumped during the picking process, thus protecting the tools from damage.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The splicing mechanism 2 includes multiple plug-in cylinders 201, which are fixedly connected to the four corners of the top of the frame plate 1. The plug-in cylinders 201 are distributed at the four corners of the frame plate 1 to provide stable support. Each plug-in cylinder 201 has a plug-in slot 203 at its top, and its bottom end penetrates the top of the frame plate 1 and is fixedly connected to a support column 202. The support column 202 supports the frame plate 1. When stacking multiple sets of frame plates 1, the support column 202 is inserted into the corresponding plug-in slot 203, thus completing the initial splicing process. The left side of the frame plate 1... Two rotating shafts 204 are rotatably connected on the right side. A locking plate 205 is fixedly connected to the outer wall of the rotating shaft 204. Two locking posts 206 are fixedly connected to the left and right sides of the frame plate 1. Bolts 207 are threaded to the far ends of the locking posts 206. A reinforcing plate 208 is fixedly connected to the outer wall of the bolt 207. The reinforcing plate 208, together with the bolt 207, can reinforce the locking plate 205, and the firmness between the frame plates 1 is also guaranteed. The splicing mechanism 2 also includes a rubber pad 209. The bottom of the rubber pad 209 is fixedly connected to the bottom of the inner side of the insertion groove 203, which can effectively reduce vibration.

[0034] Specifically, the plug-in cylinders 201 are evenly distributed at the four corners of the frame plate 1 to ensure stable support during subsequent use. Each plug-in cylinder 201 has a plug-in slot 203 at its top, and its bottom end penetrates the top of the frame plate 1 and is fixed to the support column 202. The support column 202 provides necessary support for the frame plate 1. When stacking multiple sets of frame plates 1, simply insert the support column 202 into the corresponding plug-in slot 203 to complete the initial splicing. To further enhance structural stability, two rotating shafts 204 are connected to the left and right sides of the frame plate 1, and locking plates 205 are fixed to the outer walls of the rotating shafts 204. Simultaneously, two locking columns 206 are also fixed to the left and right sides of the frame plate 1 to ensure the stability of the frame plate. To ensure the stability of the panels 1 and reduce wobbling, the locking plates 205 on both sides of the frame panel 1 need to be rotated upwards to lock onto the locking posts 206. In addition, to further enhance the stability of the splicing mechanism 2, bolts 207 are connected to the far end of multiple locking posts 206. Reinforcing plates 208 are fixed to the outer wall of the bolts 207. By rotating the bolts 207, the reinforcing plates 208 reinforce the locking plates 205, thereby achieving a quick and stable splicing. In this way, the stability of the frame panels 1 is also effectively guaranteed. The splicing mechanism 2 also includes rubber pads 209, which are placed between the insertion slots 203 and the support posts 202. They can effectively absorb and reduce vibration, thereby improving the stability and durability of the entire structure.

[0035] Reference Figure 1 , Figure 2 and Figure 4 All four corners of the bottom of the bottom shelf 1 are equipped with casters 10, and brakes 11 are installed on the outer wall of the casters 10. Multiple label plates 14 are fixedly connected to the top front side of the shelf 1. A transparent window 15 is fixedly connected to the top of the label plate 14. Handles 16 are fixedly connected to the left and right sides of the shelf 1. Anti-slip sleeves 17 are fixedly connected to the outer wall of the handles 16.

[0036] Specifically, casters 10 are provided at the four corners of the bottom shelf 1. Brakes 11 are installed on the outer side of these casters 10 so that users can quickly and stably fix the shelf 1 in position when needed. In addition, multiple label plates 14 are installed on the top front part of the shelf 1. These label plates 14 not only facilitate users to classify and label, but also effectively organize and manage items. Each label plate 14 has a transparent window 15 fixed on its top, so users can easily view the information on the label plate 14 without opening or moving any items. In order to facilitate users to move the shelf 1 in different positions, handles 16 are fixed on both the left and right sides of the shelf 1. These handles 16 allow users to comfortably grip and move the shelf 1.

[0037] Working principle: First, the inner diameter of the placement cylinder 3 varies, allowing it to be customized onto different rack plates 1 to accommodate tools of different diameters. When a tool is placed between the extrusion plates 9, the extrusion plates 9 rotate on both sides, simultaneously causing the top clamping plate 6 to clamp inward, making the rubber block 7 fit against the surface of the tool for quick clamping and fixing. At the same time, the torsion spring 8 not only increases the clamping force but also facilitates removal. After removal, the clamping plate 6 will return to its original position under the rebound of the torsion spring 8, facilitating subsequent use. The partition plate 12 is fixed on both sides of the placement cylinder 3, which not only improves the classification of tools but also prevents tools from bumping or knocking during handling.

[0038] Furthermore, the support column 202 supports the frame plate 1. When stacking multiple sets of frame plates 1, the support column 202 is inserted into the corresponding insertion slot 203 to complete the initial splicing process. In order to ensure the firmness between the frame plates 1 and reduce shaking, the locking plates 205 on both sides of the frame plate 1 are rotated upward and locked onto the locking column 206. The reinforcing plate 208 is used to reinforce the locking plate 205 by rotating the bolt 207, so as to achieve rapid splicing. The rubber pad 209 is placed between the insertion slot 203 and the support column 202, which can effectively reduce vibration.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
