Description

Technical Field

[0001] The utility model belongs to the technical field of processing tooling, and in particular relates to a static contact processing tooling. Background Art

[0002] T-type static contacts are usually used in high-voltage electrical appliances such as power equipment and switchgear. As the contact part of the current path, they are responsible for carrying current and maintaining good conductivity when the equipment is turned on and off. Their structure and material requirements are high, so during the manufacturing process, they often need to use certain tooling and equipment to ensure their processing accuracy and quality.

[0003] The complex geometric shape, high-hardness material, strict precision requirements and multi-process processing characteristics of the T-type static contact lead to many difficulties in its processing. Without processing tooling, the processing of the T-type static contact is prone to problems such as inaccurate positioning, low processing accuracy, and poor surface quality. In addition, in the multi-process processing, the stability and consistency of the workpiece cannot be guaranteed. Ultimately, although some tooling costs may be saved in the short term, in the long run it may increase rework, scrap and production cycle, leading to increased production costs and process difficulty. Summary of the invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a static contact processing tooling, which solves the problems of difficult positioning, low processing accuracy and poor surface quality during the processing of T-type static contacts.

[0005] The technical solution of the utility model is as follows: a static contact processing tool, comprising a mounting base, an OK fixture and a driving device, wherein the OK fixture comprises a middle driving end and movable ends at both ends of the driving end, when the driving end moves downward, the movable ends at both ends are squeezed and move to both sides, a supporting workpiece is arranged on the mounting base, a tool is fixedly arranged on the supporting workpiece, a groove is provided on the top end surface of the tool, the OK fixture is arranged in the groove, a T-slot is also recessed downward on the top end surface of the tool, the T-slot comprises a transverse groove and a main groove, the transverse groove is a countersunk groove on the side surface of the groove, the main groove connects the outer side surface of the tool and the transverse groove, and the countersunk groove surface of the transverse groove is parallel to the end surface of the corresponding movable end for pushing the static contact;

[0006] The groove is provided with a channel connected to the bottom end, and the driving device controls the driving end to move downward through the channel, and the movable end pushes the T-shaped static contact to be squeezed onto the sinking groove surface of the transverse groove.

[0007] By adopting the above technical solution, a groove and T-slots on both sides of the groove are provided. The T-slot corresponds to the shape of the static contact and can be inserted into the T-slot, so that the two movable ends of the OK clamp provided on the groove can simultaneously push the static contact placed on the T-slot to press it against the groove surface. By driving the driving end of an OK clamp, the static contacts on both sides can be fixed, and the main groove connects the outer side surface of the tooling and the transverse groove, so that the part of the T-type static contact located in the main groove can extend beyond the outer side surface of the tooling, and can be suitable for T-type static contacts of more sizes.

[0008] The utility model is further configured as follows: a plurality of OK clamps are arranged on the groove, and both sides of the two movable ends of each OK clamp are provided with T-shaped grooves.

[0009] By adopting the above-mentioned further setting, the tooling can have multiple T-slots to install multiple T-type static contacts at the same time. At the same time, the position of the T-slot can be determined by controlling the position where each OK fixture is placed. After the static contact is fixed on each T-slot, the machine tool can process all the static contacts on the tooling with one positioning, which can speed up the processing efficiency of the static contacts.

[0010] The utility model is further configured as follows: the driving device is a bolt, an internal thread is arranged in the channel, a countersunk through hole is arranged on the driving end, the bolt passes through the countersunk through hole and is threadedly connected in the channel, and the bolt head abuts against the countersunk surface of the countersunk through hole.

[0011] By further setting the above, the upper and lower positions of the bolts in the hole can be changed by turning the bolts, so that the up and down movement of the driving end can be controlled. By tightening the bolts, the two movable ends can firmly squeeze the static contact on the groove surface of the transverse groove to complete the fixation.

[0012] The utility model is further configured as follows: the driving device is a cylinder and an air pump, the supporting workpiece is provided with a through hole connected to the channel, and the cylinder output end is fixedly connected to the driving end through the through hole on the supporting workpiece and the channel.

[0013] By further adopting the above-mentioned arrangement, the driving end is controlled by a pneumatic device connected through a cylinder and an air pump, so that the position of the driving end can be accurately controlled by the pneumatic device, and the movement of the cylinder output end is controlled by the pressure in the air pump, so that the driving end can move up and down to squeeze the static contact on the groove surface and fix it, and the position locking of the driving end is relatively stable and not easy to shake. The pneumatic device is simple as a whole and has a fast response speed.

[0014] The utility model is further configured as follows: a cushioning piece is fixedly provided at the bottom of the supporting workpiece, the cushioning piece is fixedly connected to the mounting base plate, the cylinder is fixedly provided at the bottom of the supporting workpiece, and the gap between the supporting workpiece and the mounting base plate can accommodate the cylinder.

[0016] The utility model is further configured as follows: each OK clamp has a corresponding cylinder at the bottom, and the air inlet of each cylinder is connected to the air pump through an air pipe.

[0017] With the above further configuration, each cylinder is controlled by an air pump, which can simultaneously control the synchronous movement of all OK fixtures on the entire tooling, without the need for individual control of each cylinder, and the overall control is simpler.

[0018] A further configuration of the utility model is that the T-shaped groove is a stepped structure as a whole, and the stepped surface thereof coincides with the bottom surface of the groove.

[0019] With the above further arrangement, the upper layer of the stepped structure is wider, which can facilitate the placement of the static contact into the T-slot, and the lower layer is narrower. After the static contact is placed in, the position is more precise. After the static contact is placed in contact with the step surface, fine-tuning can be performed to adjust it to be accurately placed therein, making it convenient to manually place the static contact in the T-slot.

[0030] Embodiment 1, as Figure 1-5 As shown, a static contact processing tooling includes a mounting base plate 1, an OK fixture 41 and a driving device 6. The OK fixture 41 is a prior art including a driving end 411 located in the middle and movable ends 412 at both ends of the driving end 411. When the driving end 411 moves downward, the movable ends 412 on both sides are squeezed and move toward both sides. In this embodiment, the driving device 6 includes a pneumatic device of a cylinder and an air pump.

[0031] A support workpiece 2 is arranged on the installation base plate 1, a tooling 3 is fixedly arranged above the support workpiece 2, a padding member 21 is fixedly arranged at the bottom of the support workpiece 2, and the padding member 21 is fixedly connected to the installation base plate 1, and the fixed connection method can be threaded connection and fixing with bolts;

[0032] The cylinder is fixedly arranged at the bottom of the supporting workpiece 2 so that the movement direction of the cylinder output end is adjusted to up and down movement. The spacer 21 allows the gap between the supporting workpiece 2 and the mounting base plate 1 to accommodate the cylinder, saving the overall occupied space.

[0033] A groove 4 is provided on the top end surface of the tool 3, and the OK fixture 41 is arranged in the groove 4. A plurality of OK fixtures 41 are arranged on the groove 4. In this embodiment, nine OK fixtures 41 are evenly distributed on the groove 4. A T-slot 5 is also recessed downward on the top end surface of the tool 3. A T-slot 5 is correspondingly provided on the movable ends 412 on both sides of each OK fixture 41. In this embodiment, the number of T-slots 5 is eighteen, and they are distributed in pairs on both sides of the movable ends 412 of the nine OK fixtures 41.

[0034] The tooling 3 can have multiple T-slots 5 to simultaneously install multiple T-shaped static contacts. At the same time, the position of the T-slot 5 can be determined by controlling the position where each OK fixture 41 is placed. After the static contact is fixed on each T-slot 5, the machine tool can process all the static contacts on the tooling 3 by positioning at one time, which can speed up the processing efficiency of the static contacts.

[0035] It should be noted that a plurality of tools 3 may be arranged on the mounting base plate 1 to increase the number of T-shaped static contacts that can be fixed and processed simultaneously.

[0036] Each T-slot 5 includes a transverse slot 51 and a main slot 52. The transverse slot 51 is a countersunk slot on the side of the groove 4, and its countersunk slot surface 511 is parallel to the end surface of the corresponding movable end 412 for pushing the static contact, so that the static contact is evenly stressed, avoiding the situation where there is excessive pressure at a certain point on the static contact. The main slot 52 connects the transverse slot 51 and the outer side of the tooling 3, so that the part of the T-type static contact located in the main slot 52 can extend beyond the outer side of the tooling 3, and can be suitable for T-type static contacts of more sizes;

[0037] The T-slot 5 is a stepped structure as a whole, and its stepped surface coincides with the bottom surface of the groove 4. The upper layer of the stepped structure is wider, which can facilitate the placement of the static contact into the T-slot, and the lower layer is narrower. After the static contact is placed in, the position is more precise. After the static contact is placed in contact with the stepped surface, it can be adjusted to be accurately placed therein by fine-tuning, which is convenient for manual placement of the static contact in the T-slot 5.

[0038] The groove 4 is provided with a hole 42 connected to the bottom end. The driving device 6 controls the driving end 411 to move downward through the hole 42 , and the movable end 412 pushes the T-shaped static contact to be squeezed on the sinking groove surface 511 of the transverse groove 51 .

[0039] In this embodiment, the driving device 6 is a cylinder and an air pump, the supporting workpiece 2 is provided with a through hole aligned and connected to the channel 42, and the cylinder output end is fixedly connected to the driving end 411 through the through hole on the supporting workpiece 2 and the channel 42.

[0040] By controlling the movement of the cylinder output end through the pressure inside the air pump, the driving end 411 can be moved up and down to squeeze the static contact on the groove surface 511 and fix it. The position locking of the driving end 411 is relatively stable and not easy to shake. The pneumatic device is simple as a whole, has a fast response speed and precise position control.

[0041] Furthermore, there is a corresponding cylinder at the bottom of each OK clamp 41, and the air inlet of each cylinder is connected to the air pump through an air pipe, so that each cylinder is controlled by an air pump, and all OK clamps 41 on the entire tooling 3 can be controlled to move synchronously at the same time, without the need for individual control of each cylinder, and the overall control is simpler.

[0042] Specifically, by providing the groove 4 and the T-slots 5 on both sides of the groove 4, the T-slots 5 correspond to the shape of the static contact and can be inserted into the T-slot 5, so that the two movable ends 412 of the OK clamp 41 provided on the groove 4 can simultaneously push the static contact placed on the T-slot 5 to press it against the recessed groove surface 511. By driving the driving end 411 of an OK clamp 41, the static contacts on both sides can be fixed, and the main groove 52 connects the outer side surface of the tooling 3 and the transverse groove 51. Example

[0043] In this embodiment, the driving device 6 is selected as a bolt, and there is no need to use a spacer 21. The driving device 6 is directly fixedly connected to the mounting base plate 1 through the supporting workpiece 2. The rest of the structure is the same as that of the embodiment 1.

[0044] Furthermore, an internal thread is provided in the channel 42, and a countersunk through hole is provided on the driving end 411. The bolt passes through the countersunk through hole and is threadedly connected in the channel 42, and the head of the bolt abuts against the countersunk surface of the countersunk through hole, thereby the upper and lower positions of the bolt in the channel 42 can be changed by turning the bolt, and the up and down movement of the driving end 411 can be controlled. By tightening the bolt, the two movable ends 412 firmly squeeze the static contact on the recessed groove surface 511 of the transverse groove 51 to complete the fixation, and further, the driving end 411 and the movable ends 412 on both sides are respectively fixed to a spring ring on the side. It should be noted that this structure is a prior art for resetting in the OK clamp 41, which is not shown in the accompanying drawings. After the driving end 411 moves, the spring ring portion fixed to the driving end 411 is deformed more than the fixed portion of the movable end 412. When the bolt is turned to reset, the driving end 411 is reset to the same horizontal plane as the movable end 412 by the action of the spring ring, so as to release the static contact for people to take out.
