Description

Technical Field

[0001] The utility model relates to a marking device for machining mechanical parts, in particular to a marking device for a motor housing of a machine tool. Background Art

[0002] The motor housing, also known as the stator housing, is a basic component of the motor and is a single, inseparable part that makes up the stator assembly and the motor. After finishing the two end faces and inner and outer diameters of the motor housing, it is necessary to mill water-cooling ribs on the outer diameter of the motor housing. This machining step requires marking (marking) corresponding lines on the motor housing according to the cutting path. Existing marking operations generally use a marking needle. The marking needle is an integral rigid marking needle. Specifically, the marking needle is installed on the spindle of a machining center. The machining center uses the machine tool to mark the vertical end face where the water-cooling ribs need to be milled according to the drawing requirements. However, since each motor housing has machining errors, the following problems are prone to occur when using current marking needles for marking: the marking is too deep, resulting in the workpiece needing grinding for repair, or too shallow, resulting in unclear markings, which makes it difficult to meet actual application requirements. Utility Model Content

[0003] The purpose of the utility model is to provide a motor housing marking device for machine tools that can effectively solve the problem that when a motor housing is marked by a machining center machine tool, due to machining errors in the motor housing, the marking is too deep, resulting in the workpiece needing grinding for repair, or the marking is too shallow, resulting in unclear marking, which is difficult to meet actual application needs.

[0004] The technical solution of the utility model is:

[0005] A marking device for a motor housing for a machine tool comprises a marking sleeve rod, a spring and a marking needle rod slidably arranged in the inner hole of the marking sleeve rod, one end of the marking sleeve rod is provided with a threaded adjustment screw, the inner hole of the marking sleeve rod is provided with a limiting step, the marking needle rod is provided with a limiting portion that cooperates with the limiting step, the spring is arranged in the inner hole of the marking sleeve rod, the spring rests between the adjusting screw and the marking needle rod, one end of the marking needle rod is provided with a needle tip, the limiting portion rests on the limiting step under the action of the spring, and the needle tip of the marking needle rod extends from the other end of the marking sleeve rod to the outside of the marking sleeve rod under the action of the spring. The specific use of a motor housing marking device for a machine tool of the present invention is as follows: the motor housing marking device is installed on the spindle of a machining center machine tool through a marking sleeve rod, and the machining center machine tool marks the end face of the motor housing through the needle tip of the marking needle rod according to the requirements of the drawing. In this process, the machining error of the motor housing can be offset by the elastic deformation of the spring, so that the marking depth is not affected by the machining error of the motor housing, ensuring that the marking depth on each motor housing is consistent, thereby effectively solving the problem that when the motor housing is marked by a machining center machine tool, the marking is too deep due to the machining error of the motor housing, resulting in the workpiece needing to be repaired by grinding or the marking is too shallow, resulting in unclear marking, which is difficult to meet the actual application requirements; thereby reducing the cost of grinding and repair and the cost of unclear rework, and effectively improving work efficiency. In addition, the initial preload force of the spring acting on the marking needle rod can be adjusted by rotating the adjusting screw, thereby adjusting the force of the spring acting on the motor housing through the marking needle rod during the marking process, and then adjusting the depth of the marking.

[0006] Preferably, a locking nut is provided on the adjusting screw, the locking nut being located outside the marking sleeve and being locked to the end of the marking sleeve. Thus, after adjusting the initial preload force of the spring on the marking needle rod by rotating the adjusting screw, the locking nut is tightened to lock the position of the adjusting screw, thereby preventing the adjusting screw from loosening during use.

[0007] Preferably, one end of the adjusting screw outside the marking sleeve is provided with a bolt head or an inner polygonal hole. Thus, the adjusting screw can be conveniently rotated through the bolt head or the inner polygonal hole to adjust the initial preload force of the spring acting on the marking needle rod.

[0008] Preferably, a bolt head is provided at one end of the adjusting screw outside the marking sleeve rod, and the adjusting screw and the bolt head together form an adjusting bolt. In this way, the adjusting screw can be conveniently rotated by the bolt head to adjust the initial preload force of the spring acting on the marking needle rod.

[0009] Preferably, the marking needle rod is provided with an external thread, and the needle rod can rotate within the marking sleeve rod, and a limit nut is threadedly connected to the external thread of the marking needle rod, and the limit nut is located in the inner hole of the marking sleeve rod. The limit nut constitutes the limiting portion, and the limit nut and the inner hole of the marking sleeve rod cannot rotate relative to each other. The limit nut can slide along the inner hole of the marking sleeve rod, and one end of the spring abuts the end of the marking needle rod. In this way, the initial preload force of the spring acting on the marking needle rod can be adjusted by rotating the needle rod. Specifically, during the rotation of the needle rod, the limit nut does not rotate, thereby adjusting the distance between the end of the marking needle rod abutting the spring and the limit nut. When the distance between the end of the marking needle rod abutting the spring and the limit nut is larger, the initial preload force of the spring acting on the marking needle rod is also larger; conversely, the initial preload force of the spring acting on the marking needle rod is smaller. Thus, the initial preload force of the spring acting on the marking needle rod can be adjusted by rotating the needle rod.

[0010] Preferably, a slider is provided on the limit nut, and a limit slot is provided on the side wall of the inner hole of the marking rod. The limit slot extends axially along the marking rod, and the slider extends into the limit slot. In this way, the limit nut and the inner hole of the marking rod cannot rotate relative to each other, and the limit nut can slide along the inner hole of the marking rod.

[0011] Preferably, the end of the marking needle rod is provided with an end column, which can slide along the inner hole of the marking sleeve rod. The outer diameter of the end column is larger than the outer diameter of the marking needle rod, and one end of the spring rests on the end column.

[0012] Preferably, the marking needle rod and the needle tip are an integrally formed structure, which facilitates the actual processing and manufacturing of the marking needle rod and the needle tip.

[0013] Preferably, the marking needle rod and the needle tip are made separately, and the needle tip is detachably connected to one end of the marking needle rod. In this way, different needle tips can be selected as needed to meet different marking needs or to facilitate the replacement of worn needle tips.

[0014] Preferably, the needle tip and the marking needle rod are connected by a threaded connection or a male and female plug structure, so that the needle tip can be easily replaced and installed.

[0015] The beneficial effects of the utility model are: it can effectively solve the problem that when marking the motor housing by a machining center machine tool, due to the presence of machining errors in the motor housing, the marking is too deep, resulting in the workpiece needing grinding to repair or the marking is too shallow, resulting in unclear marking, which is difficult to meet actual application needs; thereby reducing the cost of grinding repair and the cost of unclear rework, and effectively improving work efficiency.

[0027] Specific embodiment 1, as Figure 1 As shown, a motor housing marking device for a machine tool comprises a marking sleeve rod 1, a spring 3 and a marking needle rod 2 slidably arranged in the inner hole of the marking sleeve rod 1.

A spring 3 is disposed within the inner bore of the marking rod 1, abutting between the adjustment screw 4 and the marking needle rod 2. A needle tip 2.2 is provided at one end of the marking needle rod 2. The stopper 2.1 abuts against the stop step 1.1 under the action of the spring 3. The needle tip 2.2 of the marking needle rod 2 extends from the other end of the marking rod 1 to the outside of the marking rod 1 under the action of the spring 3.

[0030] In this embodiment, the other end of the marking needle rod 2 is provided with an end post 2.0. That is, the end of the marking needle rod 2 located within the inner hole of the marking sleeve rod 1 is provided with an end post 2.0. The outer diameter of the end post 2.0 is larger than the outer diameter of the marking needle rod 2. This end post 2.0 constitutes the stopper 2.1.

[0031] In this embodiment, a bolt head 5 is provided on the end of the adjusting screw 4, located outside the marking sleeve 1. The adjusting screw 4 and the bolt head 5 together form an adjusting bolt. This facilitates practical manufacturing and allows the adjusting screw 4 to be easily rotated via the bolt head 5, thereby adjusting the initial preload force of the spring 3 on the marking needle rod 2.

[0032] The specific use of the motor housing marking device for machine tools in this embodiment is as follows: the motor housing marking device is installed on the spindle of the machining center machine tool through the marking sleeve rod 1, and the machining center machine tool marks the end face of the motor housing through the needle tip 2.2 of the marking needle rod 2 according to the requirements of the drawing. In this process, the processing error of the motor housing can be offset by the elastic deformation of the spring 3, so that the marking depth is not affected by the processing error of the motor housing, ensuring that the marking depth on each motor housing is consistent, thereby effectively solving the problem that when the motor housing is marked by the machining center machine tool, the marking is too deep due to the processing error of the motor housing, resulting in the workpiece needing to be repaired by grinding or the marking is too shallow, resulting in unclear marking, which is difficult to meet actual application needs; thereby reducing the cost of grinding repair and the cost of unclear rework, and effectively improving work efficiency.

[0033] On the other hand, the initial preload force of the spring 3 on the marking needle rod 2 can be adjusted by rotating the adjusting screw 4, thereby adjusting the force of the spring 3 acting on the motor housing through the marking needle rod 2 during the marking process, and then adjusting the depth of the marking.

[0034] Specific embodiment 2, as Figure 2 As shown, a motor housing marking device for a machine tool comprises a marking sleeve rod 1, a spring 3 and a marking needle rod 2 slidably arranged in the inner hole of the marking sleeve rod 1.

[0035] An end of the marking sleeve rod 1 is provided with an adjusting screw 4 which is threadedly connected.

[0036] A stop step 1.1 is provided within the inner bore of the marking rod 1. The marking needle rod 2 is provided with a stopper 2.1 that engages with the stopper 1.1. A spring 3 is disposed within the inner bore of the marking rod 1, abutting between the adjustment screw 4 and the marking needle rod 2. A needle tip 2.2 is provided at one end of the marking needle rod 2. The stopper 2.1 abuts against the stop step 1.1 under the action of the spring 3. The needle tip 2.2 of the marking needle rod 2 extends from the other end of the marking rod 1 to the outside of the marking rod 1 under the action of the spring 3.

[0037] In this embodiment, the other end of the marking needle rod 2 is provided with an end post 2.0. That is, the end of the marking needle rod 2 located within the inner hole of the marking sleeve rod 1 is provided with an end post 2.0. The outer diameter of the end post 2.0 is larger than the outer diameter of the marking needle rod 2. This end post 2.0 constitutes the stopper 2.1.

[0038] In this embodiment, a locking nut 6 is provided on the adjusting screw 4. The locking nut 6 is located outside the marking sleeve 1 and is locked to the end of the marking sleeve 1. In this way, the initial preload force of the spring 3 on the marking needle rod 2 can be adjusted by rotating the adjusting screw 4. On the other hand, after adjusting the initial preload force of the spring 3 on the marking needle rod 2 by rotating the adjusting screw 4, the position of the adjusting screw 4 can be locked by tightening the locking nut 6, thereby preventing the adjusting screw 4 from loosening during use.

[0039] The end of the adjusting screw 4 outside the marking sleeve rod 1 is provided with a bolt head 5 or an inner polygonal hole. In this way, the adjusting screw 4 can be easily rotated through the bolt head 5 or the inner polygonal hole to adjust the initial preload force of the spring 3 on the marking needle rod 2.

[0040] The specific use of the motor housing marking device for machine tools in this embodiment is as follows: the motor housing marking device is installed on the spindle of the machining center machine tool through the marking sleeve rod 1, and the machining center machine tool marks the end face of the motor housing through the needle tip 2.2 of the marking needle rod 2 according to the requirements of the drawing. In this process, the processing error of the motor housing can be offset by the elastic deformation of the spring 3, so that the marking depth is not affected by the processing error of the motor housing, ensuring that the marking depth on each motor housing is consistent, thereby effectively solving the problem that when the motor housing is marked by the machining center machine tool, the marking is too deep due to the processing error of the motor housing, resulting in the workpiece needing to be repaired by grinding or the marking is too shallow, resulting in unclear marking, which is difficult to meet actual application needs; thereby reducing the cost of grinding repair and the cost of unclear rework, and effectively improving work efficiency.

[0041] On the other hand, the initial preload force of the spring 3 on the marking needle rod 2 can be adjusted by rotating the adjusting screw 4, thereby adjusting the force of the spring 3 acting on the motor housing through the marking needle rod 2 during the marking process, and then adjusting the depth of the marking.

[0042] Specific embodiment three, as Figure 3 As shown, a motor housing marking device for a machine tool comprises a marking sleeve rod 1, a spring 3 and a marking needle rod 2 slidably arranged in the inner hole of the marking sleeve rod 1.

[0043] An end of the marking sleeve rod 1 is provided with an adjusting screw 4 which is threadedly connected.

[0044] A stop step 1.1 is provided within the inner bore of the marking rod 1. The marking needle rod 2 is provided with a stopper 2.1 that engages with the stopper 1.1. A spring 3 is disposed within the inner bore of the marking rod 1, abutting between the adjustment screw 4 and the marking needle rod 2. A needle tip 2.2 is provided at one end of the marking needle rod 2. The stopper 2.1 abuts against the stop step 1.1 under the action of the spring 3. The needle tip 2.2 of the marking needle rod 2 extends from the other end of the marking rod 1 to the outside of the marking rod 1 under the action of the spring 3.

[0045] In this embodiment, the marking needle rod 2 is provided with an external thread, and the needle rod can rotate within the marking sleeve rod 1. A limit nut 2.3 is threadedly connected to the external thread of the marking needle rod 2, and the limit nut 2.3 is located within the inner hole of the marking sleeve rod 1. This limit nut 2.3 constitutes the aforementioned limit portion 2.1. The limit nut 2.3 and the inner hole of the marking sleeve rod 1 cannot rotate relative to each other, but the limit nut 2.3 can slide along the inner hole of the marking sleeve rod 1. Specifically, the limit nut 2.3 is provided with a slider 2.4, and a limit groove 1.2 is provided on the side wall of the inner hole of the marking sleeve rod 1. The limit groove 1.2 extends axially along the marking sleeve rod 1. The slider 2.4 extends into the limit groove 1.2, thereby preventing the limit nut 2.3 from rotating relative to the inner hole of the marking sleeve rod 1, and allowing the limit nut 2.3 to slide along the inner hole of the marking sleeve rod 1. One end of the spring 3 abuts the end of the marking needle rod 2. In this way, the initial preload force of the spring 3 on the marking needle rod 2 can be adjusted by rotating the needle rod. Specifically, during the rotation of the needle rod, the limit nut 2.3 does not rotate, thereby adjusting the distance between the end of the marking needle rod 2 abutting against the spring 3 and the limit nut 2.3. The greater the distance between the end of the marking needle rod 2 abutting against the spring 3 and the limit nut 2.3, the greater the initial preload force of the spring 3 on the marking needle rod 2; conversely, the smaller the initial preload force of the spring 3 on the marking needle rod 2; thereby achieving the adjustment of the initial preload force of the spring 3 on the marking needle rod 2 by rotating the needle rod.

[0046] The specific use of the motor housing marking device for machine tools in this embodiment is as follows: the motor housing marking device is installed on the spindle of the machining center machine tool through the marking sleeve rod 1, and the machining center machine tool marks the end face of the motor housing through the needle tip 2.2 of the marking needle rod 2 according to the requirements of the drawing. In this process, the processing error of the motor housing can be offset by the elastic deformation of the spring 3, so that the marking depth is not affected by the processing error of the motor housing, ensuring that the marking depth on each motor housing is consistent, thereby effectively solving the problem that when the motor housing is marked by the machining center machine tool, the marking is too deep due to the processing error of the motor housing, resulting in the workpiece needing to be repaired by grinding or the marking is too shallow, resulting in unclear marking, which is difficult to meet actual application needs; thereby reducing the cost of grinding repair and the cost of unclear rework, and effectively improving work efficiency.

[0047] On the other hand, the initial preload force of the spring 3 on the marking needle rod 2 can be adjusted by rotating the needle rod, thereby adjusting the force of the spring 3 on the motor housing through the marking needle rod 2 during the marking process, and then adjusting the depth of the marking.

[0048] In one embodiment, Figure 3 As shown, one end of the adjusting screw rod 4 located outside the marking sleeve rod 1 is provided with a bolt head 5. The adjusting screw rod 4 and the bolt head 5 together constitute an adjusting bolt, and the bolt head 5 rests on the end face of the marking sleeve rod 1.

[0049] In another embodiment, referring to Figure 2 The adjusting screw 4 is provided with a locking nut 6, which is located outside the marking sleeve 1 and is locked to the end of the marking sleeve 1. A bolt head 5 or an inner polygonal hole is provided at one end of the adjusting screw 4, located outside the marking sleeve 1. This allows the initial preload force of the spring 3 on the marking needle rod 2 to be adjusted by rotating the adjusting screw 4. Furthermore, after adjusting the initial preload force of the spring 3 on the marking needle rod 2 by rotating the adjusting screw 4, the position of the adjusting screw 4 can be locked by tightening the locking nut 6, preventing the adjusting screw 4 from loosening during use.

[0050] In this embodiment, a terminal post 2.0 is provided at the end of the marking needle rod 2. The terminal post 2.0 is located within the inner hole of the marking sleeve rod 1. The terminal post 2.0 can slide along the inner hole of the marking sleeve rod 1. The outer diameter of the terminal post 2.0 is larger than the outer diameter of the marking needle rod 2. The terminal post 2.0 can rotate within the inner hole of the marking sleeve rod 1. One end of the spring 3 abuts against the terminal post 2.0.

[0051] Specific embodiment 4: The rest of the structure of this embodiment refers to specific embodiment 1, specific embodiment 2 or specific embodiment 3, the difference is that:

[0052] In one embodiment, Figure 1 、 Figure 2 As shown, the marking needle rod 2 and the needle tip 2.2 are an integrally formed structure, which facilitates the actual processing and manufacturing of the marking needle rod 2 and the needle tip 2.2.

[0053] In another embodiment, Figure 4 As shown, the marking needle rod 2 and the needle tip 2.2 are made separately, and the needle tip 2.2 is detachably connected to one end of the marking needle rod 2. In this way, different needle tips 2.2 can be selected as needed to meet different marking needs; or a worn needle tip 2.2 can be easily replaced.

[0054] In one example, the needle tip 2.2 is connected to the marking needle rod 2 via a thread, so that the needle tip 2.2 can be easily replaced and installed.

[0055] In another example, the needle tip 2.2 is connected to the marking needle rod 2 via a male-female plug structure.
