Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a push-loading type metal block processing clamp. Background Art

[0002] A stylus (or styluspen) is a small pen-shaped tool used to assist users in inputting commands to devices with touch screens, such as conference interactive tablets, tablets, mobile phones, and drawing boards. Users can interact with the device by touching the touch screen with the stylus.

[0003] In related technology, a stylus typically consists of a body and a tip. The tip is mounted at one end of the body, enabling touch operations on touch devices. The tip is typically secured to the body using an interference fit or threaded assembly. The body also contains two metal discs, one large and one small, connected by a heavier metal block to determine the stylus's posture.

[0004] During actual production, the inventors discovered that due to the limited internal space of the pen body, the metal block also needed to be made small to fit within it. To prevent material waste, CNC machining of small metal blocks requires milling with small metal strips. However, using small metal strips for milling is difficult to clamp, and loading and unloading is time-consuming, severely impacting production efficiency. Furthermore, small metal strips are difficult to position, and any deviation in the clamping position can alter the size of the machined metal block, limiting the machining yield.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0006] In view of this, the present invention aims to address the shortcomings of the existing technology, and its main purpose is to provide a push-loading type metal block processing fixture to effectively solve the technical defects of low production efficiency and production yield in the existing technology when CNC processing metal blocks.

[0009] The push rod is movably mounted on the rear side of the first clamping plate. When the first clamping block stops clamping the metal strip, the push rod can push the metal strip forward so that the front end of the metal strip protrudes from the front end of the first clamping plate.

[0010] When processing a metal block, the metal bar is first inserted into the first clamping groove, and then the metal bar is pushed forward a certain distance by the push rod so that the front end of the metal bar protrudes from the front end of the first clamping plate; finally, the metal bar is clamped and fixed by the first clamping block, and the protruding front end part of the metal bar can be milled to process the metal block.

[0011] It can be seen that the beneficial effects of the push-loading metal block processing fixture provided by the present application are: compared with the existing technology; by setting the first clamping groove and the push rod, the first clamping groove can be used to limit the left and right position of the metal bar, and the push rod can be used to push the metal bar forward a certain distance each time to perform CNC milling operations; the metal bar clamping method is simple, and there is no need to repeatedly position the metal bar; it can not only shorten the time for loading and unloading, but also improve the yield of metal block processing.

[0012] As a preferred solution: the first clamping block can be rotatably mounted on the first clamping plate, the base is provided with a cylinder, the telescopic rod of the cylinder can abut against the first clamping block and cause the first clamping block to rotate to clamp the metal strip.

[0013] As a preferred solution: the first clamping plate is provided with a first groove, in which the first pivot shaft is rotatably installed; the bottom center of the first clamping block is provided with a first pivot protrusion, which is fixedly connected to the first pivot shaft.

[0015] As a preferred solution: a first spring is provided at the top front end of the first clamping plate, and the other end of the first spring abuts against the bottom front end of the first clamping block.

[0016] As a preferred solution: the cross-section of the first clamping groove is V-shaped, and the first clamping groove runs through the front and rear ends of the first clamping plate; the top of the first clamping groove is provided with a first opening running through the top of the first clamping plate, and the width of the first opening is smaller than the width of the first clamping groove.

[0017] As a preferred solution: it also includes a first actuator; the first actuator includes a movably mounted first movable seat, a first driving cylinder fixedly mounted on the first movable seat, and a first movable plate of a telescopic rod fixedly mounted on the first driving cylinder, and the push rod is fixedly mounted on the bottom of the first movable plate and extends downward.

[0018] As a preferred solution: a second clamping assembly is also included, and the second clamping assembly is installed on a side of the base away from the first clamping assembly, and the structure of the second clamping assembly is the same as that of the first clamping assembly.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Please also refer to Figures 1 to 8 The push-loading type metal block processing fixture 10 provided in the embodiment of the present application is now described. The push-loading type metal block processing fixture 10 includes: a base 11, a first clamping assembly 12 and a push rod 13.

[0039] The first clamping assembly 12 includes a first clamping plate 121 and a first clamping block 122. The first clamping plate 121 is fixedly mounted on the base 11, and the first clamping block 122 is movably mounted on the first clamping plate 121. The first clamping plate 121 is provided with a first clamping groove 1211, which is used for inserting the metal bar 20. When the metal bar 20 is loaded into the first clamping groove 1211, the first clamping block 122 can be inserted into the first clamping groove 1211 and abut against the metal bar 20, so as to fix the metal bar 20 in the first clamping groove 1211 for milling the metal block 30. The push rod 13 is movably mounted on the rear side of the first clamping plate 121. When the first clamping block 122 stops clamping the metal bar 20, the push rod 13 can push the metal bar 20 forward so that the front end portion of the metal bar 20 protrudes from the front end of the first clamping plate 121.

[0040] It should be noted that the protruding area at the front end of the metal strip 20 is used for milling the metal block 30 .

[0041] Specifically, when processing the metal block 30, the metal bar 20 is first inserted into the first clamping groove 1211, and then the push rod 13 is used to push the metal bar 20 forward a certain distance so that the front end portion of the metal bar 20 protrudes from the front end of the first clamping plate 121; finally, the metal bar 20 is clamped and fixed by the first clamping block 122, and the protruding front end portion of the metal bar 20 can be milled to process the metal block 30.

[0042] It can be seen that by setting the first clamping plate 121, the first clamping block 122 and the push rod 13, the first clamping groove 1211 can be used to limit the left and right position of the metal bar 20, and the push rod 13 can push the metal bar 20 forward a certain distance each time. The distance that the metal bar 20 moves forward each time is constant, and there is no need to re-perform the tool alignment operation after each forward movement; this loading method can simplify the clamping of the metal bar 20 during the CNC milling process, and there is no need to repeatedly position the metal bar 20; it can not only shorten the time spent on loading and unloading, but also improve the yield rate of the metal block 30 processing.

[0043] In some embodiments of the present application, the first clamping block 122 can be rotatably mounted on the first clamping plate 121 , and the base 11 is provided with a cylinder 111 , the telescopic rod of the cylinder 111 can abut against the first clamping block 122 and cause the first clamping block 122 to rotate to clamp the metal bar 20 .

[0044] Specifically, the first clamping plate 121 is provided with a first groove 1212, in which a first pivot shaft 1213 is rotatably mounted. A first pivoting protrusion 1221 is provided at the bottom center of the first clamping block 122, which is fixedly connected to the first pivot shaft 1213. A second pivot shaft 1222 is rotatably mounted at the front end of the first clamping block 122, to which a first abutting block 1223 is fixedly mounted. When the first clamping block 122 rotates along the first pivot shaft 1213, the first abutting block 1223 is driven into the first clamping groove 1211 and abuts against the metal bar 20.

[0045] More specifically, the cylinder is mounted on the bottom of the first clamping plate 121, which has a space for the cylinder's telescopic rod to move out of the way when it is extended or retracted. The cylinder's telescopic rod can extend upward, protruding above the top of the first clamping plate 121, or retract back into the top of the first clamping plate 121. When extended, the cylinder's telescopic rod abuts the bottom rear end of the first clamping block 122, driving the first clamping block 122 to rotate, causing the front end of the first clamping block 122 to swing downward, allowing the first abutting block 1223 to enter the first clamping groove 1211 and abut against the surface of the metal bar 20. The first abutting block 1223 then presses the metal block 30 into the first clamping groove 1211, thereby clamping the metal bar 20.

[0046] Next, a first spring 1214 is mounted at the top front end of the first clamping plate 121, the other end of which abuts against the bottom front end of the first clamping block 122. When the telescopic rod of the cylinder retracts, the abutting force on the first clamping block 122 is removed. The elastic force provided by the first spring 1214 causes the front end of the first clamping block 122 to swing upward, causing the first abutting block 1223 to exit the first clamping slot 1211, thereby removing the abutting force on the metal strip 20. At this point, the push rod 13 can continue to push the metal strip 20 forward a certain distance, allowing milling of the portion of the metal strip 20 protruding from the front end of the first clamping plate 121.

[0047] Preferably, the first clamping groove 1211 has a V-shaped cross-section, extending through the front and rear ends of the first clamping plate 121. A first opening 1215 is provided at the top of the first clamping groove 1211, extending through the top of the first clamping plate 121. The width of the first opening 1215 is smaller than that of the first clamping groove 1211. This structure enhances the ability of the first clamping groove 1211 to retain the metal strip 20, reducing the risk of flying parts during milling of the metal strip 20 and improving machining reliability.

[0048] More specifically, a plurality of first clamping grooves 1211 are spaced apart along the left-right extending direction of the first clamping plate 121. Each first clamping groove 1211 can be adapted to be provided with a first abutting block 1223. A first abutting block 1223 inserted into a first clamping groove 1211 abuts against and clamps the metal bar 20 in the first clamping groove 1211. This structure can reduce the time consumed by stopping the machine for loading materials.

[0049] In some other embodiments of the present application, a first actuator component 14 is further included; the first actuator component 14 includes a movably mounted first movable seat 141, a first driving cylinder 142 fixedly mounted on the first movable seat 141, and a first movable plate 143 of a telescopic rod fixedly mounted on the first driving cylinder 142, and the push rod 13 is fixedly mounted on the bottom of the first movable plate 143 and extends downward.

[0050] For example, the first movable base 141 is fixedly mounted on the spindle end 40 of the CNC machine tool, allowing it to move synchronously with the CNC spindle. The first drive cylinder 142 then drives the first movable plate 143 up and down to adjust the height of the telescopic rod, preferably so that the push rod 13 can push the metal bar 20. Each time the metal bar 20 is fed forward, the spindle moves, which in turn synchronizes with the push rod 13, thereby moving the metal bar 20 forward.

[0051] In other embodiments of the present application, a second clamping assembly 15 and a rotational actuator assembly 16 are further included. The second clamping assembly 15 is mounted on the side of the base 11 facing away from the first clamping assembly 12. The structure of the second clamping assembly 15 is the same as that of the first clamping assembly 12. The rotational actuator assembly 16 includes two rotating bases 161 and a first motor 162 for driving one of the rotating bases 161 to rotate. The base 11 is fixedly mounted on the two rotating bases 161. When the rotating bases 161 rotate, the first clamping assembly 12 or the second clamping assembly 15 can be switched to face upward.

[0052] Specifically, by setting up a second clamping assembly 15 with the same structure as the first clamping assembly 12, the rotary actuator can be used to switch the first clamping assembly 12 or the second clamping assembly 15 to be set upward for CNC milling of the metal block 30; the operator can load the metal bar 20 to the first clamping assembly 12 and the second clamping assembly 15 at the same time, reducing the time spent on repeated shutdowns to load the metal bar 20, and further improving production efficiency.

[0053] The above is merely a preferred embodiment of the present invention and only specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
